cf0f779ad4 feat: introduce spec-workflow and upgrade frontend dependencies
This commit introduces the spec-workflow, a set of templates for creating design, product, requirements, and other specification documents. These templates are added to both the root directory and the `apps/frontend` workspace.

Additionally, this commit upgrades the frontend development dependencies for the Astro application. The key changes include:
- Migration from `@astrojs/tailwind` to `@tailwindcss/vite` for Tailwind CSS integration.
- Deletion of the `postcss.config.cjs` file, as it is no longer needed with the new setup.
- Updates to `astro.config.mjs` to use the new Vite plugin for Tailwind CSS.
- General upgrade of Astro and other related dependencies in `apps/frontend/package.json` and the corresponding `pnpm-lock.yaml` file.

# Repository Guidelines
Astro frontend + Payload CMS backend monorepo for website migration.
## Quick Reference
| Command | Purpose |
|---------|---------|
| `pnpm install` | Sync dependencies |
| `pnpm dev` | Start dev server (Astro at :4321) |
| `pnpm test:unit` | Run Vitest tests |
| `pnpm test:e2e` | Run Playwright tests |
| `pnpm build` | Production build |
## Module Locations
| Type | Location |
|------|----------|
| Frontend components | `frontend/src/components` |
| Frontend routes | `frontend/src/pages` |
| Frontend shared | `frontend/src/services` or `frontend/src/lib` |
| Backend collections | `backend/src/collections` |
| Backend auth/integrations | `backend/src` |
| Contract tests | `backend/tests` |
| Specs | `specs/001-users-pukpuk-dev/` |
## Coding Conventions
- **Frontend**: TypeScript/TSX with strict typing. `PascalCase` for Astro components, `camelCase` for variables/functions, `kebab-case` for file names.
- **Backend**: Payload collections use singular `PascalCase` with `kebab-case` slugs.
- **Testing**: Vitest suites beside modules (`*.spec.ts`), Playwright specs in `frontend/tests/e2e/`.
## Git Workflow
- **Conventional Commits**: `feat:`, `fix:`, `chore:`, etc.
- **PRs**: Include test results, screenshots for UX changes, schema updates.
## Security
- Store secrets in `.env` (never commit)
- Required: `PAYLOAD_CMS_URL`, `PAYLOAD_CMS_API_KEY`
## BMAD Agents & Tasks
This project uses BMAD-METHOD for structured development. Agent and task definitions
are managed in `.bmad-core/` and auto-generated into this file.
**Useful commands:**
- `npx bmad-method list:agents` - List available agents
- `npx bmad-method install -f -i codex` - Regenerate Codex section
- `npx bmad-method install -f -i opencode` - Regenerate OpenCode section
For agent/task details, see:
- `.bmad-core/agents/` - Agent definitions
- `.bmad-core/tasks/` - Task definitions
- `.bmad-core/user-guide.md` - Full BMAD documentation

# BMAD-METHOD Agents and Tasks
This section is auto-generated by BMAD-METHOD for Codex. Codex merges this AGENTS.md into context.
## How To Use With Codex
- Codex CLI: run `codex` in this project. Reference an agent naturally, e.g., "As dev, implement ...".
- Codex Web: open this repo and reference roles the same way; Codex reads `AGENTS.md`.
- Commit `.bmad-core` and this `AGENTS.md` file to your repo so Codex (Web/CLI) can read full agent definitions.
- Refresh this section after agent updates: `npx bmad-method install -f -i codex`.
### Helpful Commands
- List agents: `npx bmad-method list:agents`
- Reinstall BMAD core and regenerate AGENTS.md: `npx bmad-method install -f -i codex`
- Validate configuration: `npx bmad-method validate`

name: Confidence Check
description: Pre-implementation confidence assessment (≥90% required). Use before starting any implementation to verify readiness with duplicate check, architecture compliance, official docs verification, OSS references, and root cause identification.
allowed-tools: Read, Grep, Glob, WebFetch, WebSearch
---
# Confidence Check Skill
## Purpose
Prevents wrong-direction execution by assessing confidence **BEFORE** starting implementation.
**Requirement**: ≥90% confidence to proceed with implementation.
**Test Results** (2025-10-21):
- Precision: 1.000 (no false positives)
- Recall: 1.000 (no false negatives)
- 8/8 test cases passed
## When to Use
Use this skill BEFORE implementing any task to ensure:
- No duplicate implementations exist
- Architecture compliance verified
- Official documentation reviewed
- Working OSS implementations found
- Root cause properly identified
## Confidence Assessment Criteria
Calculate confidence score (0.0 - 1.0) based on 5 checks:
### 1. No Duplicate Implementations? (25%)
**Check**: Search codebase for existing functionality
```bash
# Use Grep to search for similar functions
# Use Glob to find related modules
```
✅ Pass if no duplicates found
❌ Fail if similar implementation exists
### 2. Architecture Compliance? (25%)
**Check**: Verify tech stack alignment
- Read `CLAUDE.md`, `PLANNING.md`
- Confirm existing patterns used
- Avoid reinventing existing solutions
✅ Pass if uses existing tech stack (e.g., Supabase, UV, pytest)
❌ Fail if introduces new dependencies unnecessarily
### 3. Official Documentation Verified? (20%)
**Check**: Review official docs before implementation
- Use Context7 MCP for official docs
- Use WebFetch for documentation URLs
- Verify API compatibility
✅ Pass if official docs reviewed
❌ Fail if relying on assumptions
### 4. Working OSS Implementations Referenced? (15%)
**Check**: Find proven implementations
- Use Tavily MCP or WebSearch
- Search GitHub for examples
- Verify working code samples
✅ Pass if OSS reference found
❌ Fail if no working examples
### 5. Root Cause Identified? (15%)
**Check**: Understand the actual problem
- Analyze error messages
- Check logs and stack traces
- Identify underlying issue
✅ Pass if root cause clear
❌ Fail if symptoms unclear
## Confidence Score Calculation
```
Total = Check1 (25%) + Check2 (25%) + Check3 (20%) + Check4 (15%) + Check5 (15%)
If Total >= 0.90: ✅ Proceed with implementation
If Total >= 0.70: ⚠️ Present alternatives, ask questions
If Total < 0.70: ❌ STOP - Request more context
```
## Output Format
```
📋 Confidence Checks:
✅ No duplicate implementations found
✅ Uses existing tech stack
✅ Official documentation verified
✅ Working OSS implementation found
✅ Root cause identified
📊 Confidence: 1.00 (100%)
✅ High confidence - Proceeding to implementation
```
## Implementation Details
The TypeScript implementation is available in `confidence.ts` for reference, containing:
- `confidenceCheck(context)` - Main assessment function
- Detailed check implementations
- Context interface definitions
## ROI
**Token Savings**: Spend 100-200 tokens on confidence check to save 5,000-50,000 tokens on wrong-direction work.
**Success Rate**: 100% precision and recall in production testing.

name: agent-browser
description: Automates browser interactions for web testing, form filling, screenshots, and data extraction. Use when the user needs to navigate websites, interact with web pages, fill forms, take screenshots, test web applications, or extract information from web pages.
allowed-tools: Bash(agent-browser:*)
---
# Browser Automation with agent-browser
## Quick start
```bash
agent-browser open <url> # Navigate to page
agent-browser snapshot -i # Get interactive elements with refs
agent-browser click @e1 # Click element by ref
agent-browser fill @e2 "text" # Fill input by ref
agent-browser close # Close browser
```
## Core workflow
1. Navigate: `agent-browser open <url>`
2. Snapshot: `agent-browser snapshot -i` (returns elements with refs like `@e1`, `@e2`)
3. Interact using refs from the snapshot
4. Re-snapshot after navigation or significant DOM changes
## Commands
### Navigation
```bash
agent-browser open <url> # Navigate to URL (aliases: goto, navigate)
# Supports: https://, http://, file://, about:, data://
# Auto-prepends https:// if no protocol given
agent-browser back # Go back
agent-browser forward # Go forward
agent-browser reload # Reload page
agent-browser close # Close browser (aliases: quit, exit)
agent-browser connect 9222 # Connect to browser via CDP port
```
### Snapshot (page analysis)
```bash
agent-browser snapshot # Full accessibility tree
agent-browser snapshot -i # Interactive elements only (recommended)
agent-browser snapshot -c # Compact output
agent-browser snapshot -d 3 # Limit depth to 3
agent-browser snapshot -s "#main" # Scope to CSS selector
```
### Interactions (use @refs from snapshot)
```bash
agent-browser click @e1 # Click
agent-browser dblclick @e1 # Double-click
agent-browser focus @e1 # Focus element
agent-browser fill @e2 "text" # Clear and type
agent-browser type @e2 "text" # Type without clearing
agent-browser press Enter # Press key (alias: key)
agent-browser press Control+a # Key combination
agent-browser keydown Shift # Hold key down
agent-browser keyup Shift # Release key
agent-browser hover @e1 # Hover
agent-browser check @e1 # Check checkbox
agent-browser uncheck @e1 # Uncheck checkbox
agent-browser select @e1 "value" # Select dropdown option
agent-browser select @e1 "a" "b" # Select multiple options
agent-browser scroll down 500 # Scroll page (default: down 300px)
agent-browser scrollintoview @e1 # Scroll element into view (alias: scrollinto)
agent-browser drag @e1 @e2 # Drag and drop
agent-browser upload @e1 file.pdf # Upload files
```
### Get information
```bash
agent-browser get text @e1 # Get element text
agent-browser get html @e1 # Get innerHTML
agent-browser get value @e1 # Get input value
agent-browser get attr @e1 href # Get attribute
agent-browser get title # Get page title
agent-browser get url # Get current URL
agent-browser get count ".item" # Count matching elements
agent-browser get box @e1 # Get bounding box
agent-browser get styles @e1 # Get computed styles (font, color, bg, etc.)
```
### Check state
```bash
agent-browser is visible @e1 # Check if visible
agent-browser is enabled @e1 # Check if enabled
agent-browser is checked @e1 # Check if checked
```
### Screenshots & PDF
```bash
agent-browser screenshot # Save to a temporary directory
agent-browser screenshot path.png # Save to a specific path
agent-browser screenshot --full # Full page
agent-browser pdf output.pdf # Save as PDF
```
### Video recording
```bash
agent-browser record start ./demo.webm # Start recording (uses current URL + state)
agent-browser click @e1 # Perform actions
agent-browser record stop # Stop and save video
agent-browser record restart ./take2.webm # Stop current + start new recording
```
Recording creates a fresh context but preserves cookies/storage from your session. If no URL is provided, it
automatically returns to your current page. For smooth demos, explore first, then start recording.
### Wait
```bash
agent-browser wait @e1 # Wait for element
agent-browser wait 2000 # Wait milliseconds
agent-browser wait --text "Success" # Wait for text (or -t)
agent-browser wait --url "**/dashboard" # Wait for URL pattern (or -u)
agent-browser wait --load networkidle # Wait for network idle (or -l)
agent-browser wait --fn "window.ready" # Wait for JS condition (or -f)
```
### Mouse control
```bash
agent-browser mouse move 100 200 # Move mouse
agent-browser mouse down left # Press button
agent-browser mouse up left # Release button
agent-browser mouse wheel 100 # Scroll wheel
```
### Semantic locators (alternative to refs)
```bash
agent-browser find role button click --name "Submit"
agent-browser find text "Sign In" click
agent-browser find text "Sign In" click --exact # Exact match only
agent-browser find label "Email" fill "user@test.com"

# Authentication Patterns
Patterns for handling login flows, session persistence, and authenticated browsing.
## Basic Login Flow
```bash
# Navigate to login page
agent-browser open https://app.example.com/login
agent-browser wait --load networkidle
# Get form elements
agent-browser snapshot -i
# Output: @e1 [input type="email"], @e2 [input type="password"], @e3 [button] "Sign In"
# Fill credentials
agent-browser fill @e1 "user@example.com"
agent-browser fill @e2 "password123"
# Submit
agent-browser click @e3
agent-browser wait --load networkidle
# Verify login succeeded
agent-browser get url # Should be dashboard, not login
```
## Saving Authentication State
After logging in, save state for reuse:
```bash
# Login first (see above)
agent-browser open https://app.example.com/login
agent-browser snapshot -i
agent-browser fill @e1 "user@example.com"
agent-browser fill @e2 "password123"
agent-browser click @e3
agent-browser wait --url "**/dashboard"
# Save authenticated state
agent-browser state save ./auth-state.json
```
## Restoring Authentication
Skip login by loading saved state:
```bash
# Load saved auth state
agent-browser state load ./auth-state.json
# Navigate directly to protected page
agent-browser open https://app.example.com/dashboard
# Verify authenticated
agent-browser snapshot -i
```
## OAuth / SSO Flows
For OAuth redirects:
```bash
# Start OAuth flow
agent-browser open https://app.example.com/auth/google
# Handle redirects automatically
agent-browser wait --url "**/accounts.google.com**"
agent-browser snapshot -i
# Fill Google credentials
agent-browser fill @e1 "user@gmail.com"
agent-browser click @e2 # Next button
agent-browser wait 2000
agent-browser snapshot -i
agent-browser fill @e3 "password"
agent-browser click @e4 # Sign in
# Wait for redirect back
agent-browser wait --url "**/app.example.com**"
agent-browser state save ./oauth-state.json
```
## Two-Factor Authentication
Handle 2FA with manual intervention:
```bash
# Login with credentials
agent-browser open https://app.example.com/login --headed # Show browser
agent-browser snapshot -i
agent-browser fill @e1 "user@example.com"
agent-browser fill @e2 "password123"
agent-browser click @e3
# Wait for user to complete 2FA manually
echo "Complete 2FA in the browser window..."
agent-browser wait --url "**/dashboard" --timeout 120000
# Save state after 2FA
agent-browser state save ./2fa-state.json
```
## HTTP Basic Auth
For sites using HTTP Basic Authentication:
```bash
# Set credentials before navigation
agent-browser set credentials username password
# Navigate to protected resource
agent-browser open https://protected.example.com/api
```
## Cookie-Based Auth
Manually set authentication cookies:
```bash
# Set auth cookie
agent-browser cookies set session_token "abc123xyz"
# Navigate to protected page
agent-browser open https://app.example.com/dashboard
```
## Token Refresh Handling
For sessions with expiring tokens:
```bash
#!/bin/bash
# Wrapper that handles token refresh
STATE_FILE="./auth-state.json"
# Try loading existing state
if [[ -f "$STATE_FILE" ]]; then
agent-browser state load "$STATE_FILE"
agent-browser open https://app.example.com/dashboard
# Check if session is still valid
URL=$(agent-browser get url)
if [[ "$URL" == *"/login"* ]]; then
echo "Session expired, re-authenticating..."
# Perform fresh login
agent-browser snapshot -i
agent-browser fill @e1 "$USERNAME"
agent-browser fill @e2 "$PASSWORD"
agent-browser click @e3
agent-browser wait --url "**/dashboard"
agent-browser state save "$STATE_FILE"
fi
else
# First-time login
agent-browser open https://app.example.com/login
# ... login flow ...
fi
```
## Security Best Practices
1. **Never commit state files** - They contain session tokens
```bash
echo "*.auth-state.json" >> .gitignore
```
2. **Use environment variables for credentials**
```bash
agent-browser fill @e1 "$APP_USERNAME"
agent-browser fill @e2 "$APP_PASSWORD"
```
3. **Clean up after automation**
```bash
agent-browser cookies clear
rm -f ./auth-state.json
```
4. **Use short-lived sessions for CI/CD**
```bash
# Don't persist state in CI
agent-browser open https://app.example.com/login
# ... login and perform actions ...
agent-browser close # Session ends, nothing persisted
```

# Proxy Support
Configure proxy servers for browser automation, useful for geo-testing, rate limiting avoidance, and corporate environments.
## Basic Proxy Configuration
Set proxy via environment variable before starting:
```bash
# HTTP proxy
export HTTP_PROXY="http://proxy.example.com:8080"
agent-browser open https://example.com
# HTTPS proxy
export HTTPS_PROXY="https://proxy.example.com:8080"
agent-browser open https://example.com
# Both
export HTTP_PROXY="http://proxy.example.com:8080"
export HTTPS_PROXY="http://proxy.example.com:8080"
agent-browser open https://example.com
```
## Authenticated Proxy
For proxies requiring authentication:
```bash
# Include credentials in URL
export HTTP_PROXY="http://username:password@proxy.example.com:8080"
agent-browser open https://example.com
```
## SOCKS Proxy
```bash
# SOCKS5 proxy
export ALL_PROXY="socks5://proxy.example.com:1080"
agent-browser open https://example.com
# SOCKS5 with auth
export ALL_PROXY="socks5://user:pass@proxy.example.com:1080"
agent-browser open https://example.com
```
## Proxy Bypass
Skip proxy for specific domains:
```bash
# Bypass proxy for local addresses
export NO_PROXY="localhost,127.0.0.1,.internal.company.com"
agent-browser open https://internal.company.com # Direct connection
agent-browser open https://external.com # Via proxy
```
## Common Use Cases
### Geo-Location Testing
```bash
#!/bin/bash
# Test site from different regions using geo-located proxies
PROXIES=(
"http://us-proxy.example.com:8080"
"http://eu-proxy.example.com:8080"
"http://asia-proxy.example.com:8080"
)
for proxy in "${PROXIES[@]}"; do
export HTTP_PROXY="$proxy"
export HTTPS_PROXY="$proxy"
region=$(echo "$proxy" | grep -oP '^\w+-\w+')
echo "Testing from: $region"
agent-browser --session "$region" open https://example.com
agent-browser --session "$region" screenshot "./screenshots/$region.png"
agent-browser --session "$region" close
done
```
### Rotating Proxies for Scraping
```bash
#!/bin/bash
# Rotate through proxy list to avoid rate limiting
PROXY_LIST=(
"http://proxy1.example.com:8080"
"http://proxy2.example.com:8080"
"http://proxy3.example.com:8080"
)
URLS=(
"https://site.com/page1"
"https://site.com/page2"
"https://site.com/page3"
)
for i in "${!URLS[@]}"; do
proxy_index=$((i % ${#PROXY_LIST[@]}))
export HTTP_PROXY="${PROXY_LIST[$proxy_index]}"
export HTTPS_PROXY="${PROXY_LIST[$proxy_index]}"
agent-browser open "${URLS[$i]}"
agent-browser get text body > "output-$i.txt"
agent-browser close
sleep 1 # Polite delay
done
```
### Corporate Network Access
```bash
#!/bin/bash
# Access internal sites via corporate proxy
export HTTP_PROXY="http://corpproxy.company.com:8080"
export HTTPS_PROXY="http://corpproxy.company.com:8080"
export NO_PROXY="localhost,127.0.0.1,.company.com"
# External sites go through proxy
agent-browser open https://external-vendor.com
# Internal sites bypass proxy
agent-browser open https://intranet.company.com
```
## Verifying Proxy Connection
```bash
# Check your apparent IP
agent-browser open https://httpbin.org/ip
agent-browser get text body
# Should show proxy's IP, not your real IP
```
## Troubleshooting
### Proxy Connection Failed
```bash
# Test proxy connectivity first
curl -x http://proxy.example.com:8080 https://httpbin.org/ip
# Check if proxy requires auth
export HTTP_PROXY="http://user:pass@proxy.example.com:8080"
```
### SSL/TLS Errors Through Proxy
Some proxies perform SSL inspection. If you encounter certificate errors:
```bash
# For testing only - not recommended for production
agent-browser open https://example.com --ignore-https-errors
```
### Slow Performance
```bash
# Use proxy only when necessary
export NO_PROXY="*.cdn.com,*.static.com" # Direct CDN access
```
## Best Practices
1. **Use environment variables** - Don't hardcode proxy credentials
2. **Set NO_PROXY appropriately** - Avoid routing local traffic through proxy
3. **Test proxy before automation** - Verify connectivity with simple requests
4. **Handle proxy failures gracefully** - Implement retry logic for unstable proxies
5. **Rotate proxies for large scraping jobs** - Distribute load and avoid bans

# Session Management
Run multiple isolated browser sessions concurrently with state persistence.
## Named Sessions
Use `--session` flag to isolate browser contexts:
```bash
# Session 1: Authentication flow
agent-browser --session auth open https://app.example.com/login
# Session 2: Public browsing (separate cookies, storage)
agent-browser --session public open https://example.com
# Commands are isolated by session
agent-browser --session auth fill @e1 "user@example.com"
agent-browser --session public get text body
```
## Session Isolation Properties
Each session has independent:
- Cookies
- LocalStorage / SessionStorage
- IndexedDB
- Cache
- Browsing history
- Open tabs
## Session State Persistence
### Save Session State
```bash
# Save cookies, storage, and auth state
agent-browser state save /path/to/auth-state.json
```
### Load Session State
```bash
# Restore saved state
agent-browser state load /path/to/auth-state.json
# Continue with authenticated session
agent-browser open https://app.example.com/dashboard
```
### State File Contents
```json
{
"cookies": [...],
"localStorage": {...},
"sessionStorage": {...},
"origins": [...]
}
```
## Common Patterns
### Authenticated Session Reuse
```bash
#!/bin/bash
# Save login state once, reuse many times
STATE_FILE="/tmp/auth-state.json"
# Check if we have saved state
if [[ -f "$STATE_FILE" ]]; then
agent-browser state load "$STATE_FILE"
agent-browser open https://app.example.com/dashboard
else
# Perform login
agent-browser open https://app.example.com/login
agent-browser snapshot -i
agent-browser fill @e1 "$USERNAME"
agent-browser fill @e2 "$PASSWORD"
agent-browser click @e3
agent-browser wait --load networkidle
# Save for future use
agent-browser state save "$STATE_FILE"
fi
```
### Concurrent Scraping
```bash
#!/bin/bash
# Scrape multiple sites concurrently
# Start all sessions
agent-browser --session site1 open https://site1.com &
agent-browser --session site2 open https://site2.com &
agent-browser --session site3 open https://site3.com &
wait
# Extract from each
agent-browser --session site1 get text body > site1.txt
agent-browser --session site2 get text body > site2.txt
agent-browser --session site3 get text body > site3.txt
# Cleanup
agent-browser --session site1 close
agent-browser --session site2 close
agent-browser --session site3 close
```
### A/B Testing Sessions
```bash
# Test different user experiences
agent-browser --session variant-a open "https://app.com?variant=a"
agent-browser --session variant-b open "https://app.com?variant=b"
# Compare
agent-browser --session variant-a screenshot /tmp/variant-a.png
agent-browser --session variant-b screenshot /tmp/variant-b.png
```
## Default Session
When `--session` is omitted, commands use the default session:
```bash
# These use the same default session
agent-browser open https://example.com
agent-browser snapshot -i
agent-browser close # Closes default session
```
## Session Cleanup
```bash
# Close specific session
agent-browser --session auth close
# List active sessions
agent-browser session list
```
## Best Practices
### 1. Name Sessions Semantically
```bash
# GOOD: Clear purpose
agent-browser --session github-auth open https://github.com
agent-browser --session docs-scrape open https://docs.example.com
# AVOID: Generic names
agent-browser --session s1 open https://github.com
```
### 2. Always Clean Up
```bash
# Close sessions when done
agent-browser --session auth close
agent-browser --session scrape close
```
### 3. Handle State Files Securely
```bash
# Don't commit state files (contain auth tokens!)
echo "*.auth-state.json" >> .gitignore
# Delete after use
rm /tmp/auth-state.json
```
### 4. Timeout Long Sessions
```bash
# Set timeout for automated scripts
timeout 60 agent-browser --session long-task get text body
```

# Snapshot + Refs Workflow
The core innovation of agent-browser: compact element references that reduce context usage dramatically for AI agents.
## How It Works
### The Problem
Traditional browser automation sends full DOM to AI agents:
```
Full DOM/HTML sent → AI parses → Generates CSS selector → Executes action
~3000-5000 tokens per interaction
```
### The Solution
agent-browser uses compact snapshots with refs:
```
Compact snapshot → @refs assigned → Direct ref interaction
~200-400 tokens per interaction
```
## The Snapshot Command
```bash
# Basic snapshot (shows page structure)
agent-browser snapshot
# Interactive snapshot (-i flag) - RECOMMENDED
agent-browser snapshot -i
```
### Snapshot Output Format
```
Page: Example Site - Home
URL: https://example.com
@e1 [header]
@e2 [nav]
@e3 [a] "Home"
@e4 [a] "Products"
@e5 [a] "About"
@e6 [button] "Sign In"
@e7 [main]
@e8 [h1] "Welcome"
@e9 [form]
@e10 [input type="email"] placeholder="Email"
@e11 [input type="password"] placeholder="Password"
@e12 [button type="submit"] "Log In"
@e13 [footer]
@e14 [a] "Privacy Policy"
```
## Using Refs
Once you have refs, interact directly:
```bash
# Click the "Sign In" button
agent-browser click @e6
# Fill email input
agent-browser fill @e10 "user@example.com"
# Fill password
agent-browser fill @e11 "password123"
# Submit the form
agent-browser click @e12
```
## Ref Lifecycle
**IMPORTANT**: Refs are invalidated when the page changes!
```bash
# Get initial snapshot
agent-browser snapshot -i
# @e1 [button] "Next"
# Click triggers page change
agent-browser click @e1
# MUST re-snapshot to get new refs!
agent-browser snapshot -i
# @e1 [h1] "Page 2" ← Different element now!
```
## Best Practices
### 1. Always Snapshot Before Interacting
```bash
# CORRECT
agent-browser open https://example.com
agent-browser snapshot -i # Get refs first
agent-browser click @e1 # Use ref
# WRONG
agent-browser open https://example.com
agent-browser click @e1 # Ref doesn't exist yet!
```
### 2. Re-Snapshot After Navigation
```bash
agent-browser click @e5 # Navigates to new page
agent-browser snapshot -i # Get new refs
agent-browser click @e1 # Use new refs
```
### 3. Re-Snapshot After Dynamic Changes
```bash
agent-browser click @e1 # Opens dropdown
agent-browser snapshot -i # See dropdown items
agent-browser click @e7 # Select item
```
### 4. Snapshot Specific Regions
For complex pages, snapshot specific areas:
```bash
# Snapshot just the form
agent-browser snapshot @e9
```
## Ref Notation Details

│ │ └─ Key attributes shown
│ └─ HTML tag name
└─ Unique ref ID
```
### Common Patterns
```
@e1 [button] "Submit" # Button with text
@e2 [input type="email"] # Email input
@e3 [input type="password"] # Password input
@e4 [a href="/page"] "Link Text" # Anchor link
@e5 [select] # Dropdown
@e6 [textarea] placeholder="Message" # Text area
@e7 [div class="modal"] # Container (when relevant)
@e8 [img alt="Logo"] # Image
@e9 [checkbox] checked # Checked checkbox
@e10 [radio] selected # Selected radio
```
## Troubleshooting
### "Ref not found" Error
```bash
# Ref may have changed - re-snapshot
agent-browser snapshot -i
```
### Element Not Visible in Snapshot
```bash
# Scroll to reveal element
agent-browser scroll --bottom
agent-browser snapshot -i
# Or wait for dynamic content
agent-browser wait 1000
agent-browser snapshot -i
```
### Too Many Elements
```bash
# Snapshot specific container
agent-browser snapshot @e5
# Or use get text for content-only extraction
agent-browser get text @e5
```

# Video Recording
Capture browser automation sessions as video for debugging, documentation, or verification.
## Basic Recording
```bash
# Start recording
agent-browser record start ./demo.webm
# Perform actions
agent-browser open https://example.com
agent-browser snapshot -i
agent-browser click @e1
agent-browser fill @e2 "test input"
# Stop and save
agent-browser record stop
```
## Recording Commands
```bash
# Start recording to file
agent-browser record start ./output.webm
# Stop current recording
agent-browser record stop
# Restart with new file (stops current + starts new)
agent-browser record restart ./take2.webm
```
## Use Cases
### Debugging Failed Automation
```bash
#!/bin/bash
# Record automation for debugging
agent-browser record start ./debug-$(date +%Y%m%d-%H%M%S).webm
# Run your automation
agent-browser open https://app.example.com
agent-browser snapshot -i
agent-browser click @e1 || {
echo "Click failed - check recording"
agent-browser record stop
exit 1
}
agent-browser record stop
```
### Documentation Generation
```bash
#!/bin/bash
# Record workflow for documentation
agent-browser record start ./docs/how-to-login.webm
agent-browser open https://app.example.com/login
agent-browser wait 1000 # Pause for visibility
agent-browser snapshot -i
agent-browser fill @e1 "demo@example.com"
agent-browser wait 500
agent-browser fill @e2 "password"
agent-browser wait 500
agent-browser click @e3
agent-browser wait --load networkidle
agent-browser wait 1000 # Show result
agent-browser record stop
```
### CI/CD Test Evidence
```bash
#!/bin/bash
# Record E2E test runs for CI artifacts
TEST_NAME="${1:-e2e-test}"
RECORDING_DIR="./test-recordings"
mkdir -p "$RECORDING_DIR"
agent-browser record start "$RECORDING_DIR/$TEST_NAME-$(date +%s).webm"
# Run test
if run_e2e_test; then
echo "Test passed"
else
echo "Test failed - recording saved"
fi
agent-browser record stop
```
## Best Practices
### 1. Add Pauses for Clarity
```bash
# Slow down for human viewing
agent-browser click @e1
agent-browser wait 500 # Let viewer see result
```
### 2. Use Descriptive Filenames
```bash
# Include context in filename
agent-browser record start ./recordings/login-flow-2024-01-15.webm
agent-browser record start ./recordings/checkout-test-run-42.webm
```
### 3. Handle Recording in Error Cases
```bash
#!/bin/bash
set -e
cleanup() {
agent-browser record stop 2>/dev/null || true
agent-browser close 2>/dev/null || true
}
trap cleanup EXIT
agent-browser record start ./automation.webm
# ... automation steps ...
```
### 4. Combine with Screenshots
```bash
# Record video AND capture key frames
agent-browser record start ./flow.webm
agent-browser open https://example.com
agent-browser screenshot ./screenshots/step1-homepage.png
agent-browser click @e1
agent-browser screenshot ./screenshots/step2-after-click.png
agent-browser record stop
```
## Output Format
- Default format: WebM (VP8/VP9 codec)
- Compatible with all modern browsers and video players
- Compressed but high quality
## Limitations
- Recording adds slight overhead to automation
- Large recordings can consume significant disk space
- Some headless environments may have codec limitations

name: agent-md-refactor
description: Refactor bloated AGENTS.md, CLAUDE.md, or similar agent instruction files to follow progressive disclosure principles. Splits monolithic files into organized, linked documentation.
license: MIT
---
# Agent MD Refactor
Refactor bloated agent instruction files (AGENTS.md, CLAUDE.md, COPILOT.md, etc.) to follow **progressive disclosure principles** - keeping essentials at root and organizing the rest into linked, categorized files.
---
## Triggers
Use this skill when:
- "refactor my AGENTS.md" / "refactor my CLAUDE.md"
- "split my agent instructions"
- "organize my CLAUDE.md file"
- "my AGENTS.md is too long"
- "progressive disclosure for my instructions"
- "clean up my agent config"
---
## Quick Reference
| Phase | Action | Output |
|-------|--------|--------|
| 1. Analyze | Find contradictions | List of conflicts to resolve |
| 2. Extract | Identify essentials | Core instructions for root file |
| 3. Categorize | Group remaining instructions | Logical categories |
| 4. Structure | Create file hierarchy | Root + linked files |
| 5. Prune | Flag for deletion | Redundant/vague instructions |
---
## Process
### Phase 1: Find Contradictions
Identify any instructions that conflict with each other.
**Look for:**
- Contradictory style guidelines (e.g., "use semicolons" vs "no semicolons")
- Conflicting workflow instructions
- Incompatible tool preferences
- Mutually exclusive patterns
**For each contradiction found:**
```markdown
## Contradiction Found
**Instruction A:** [quote]
**Instruction B:** [quote]
**Question:** Which should take precedence, or should both be conditional?
```
Ask the user to resolve before proceeding.
---
### Phase 2: Identify the Essentials
Extract ONLY what belongs in the root agent file. The root should be minimal - information that applies to **every single task**.
**Essential content (keep in root):**
| Category | Example |
|----------|---------|
| Project description | One sentence: "A React dashboard for analytics" |
| Package manager | Only if not npm (e.g., "Uses pnpm") |
| Non-standard commands | Custom build/test/typecheck commands |
| Critical overrides | Things that MUST override defaults |
| Universal rules | Applies to 100% of tasks |
**NOT essential (move to linked files):**
- Language-specific conventions
- Testing guidelines
- Code style details
- Framework patterns
- Documentation standards
- Git workflow details
---
### Phase 3: Group the Rest
Organize remaining instructions into logical categories.
**Common categories:**
| Category | Contents |
|----------|----------|
| `typescript.md` | TS conventions, type patterns, strict mode rules |
| `testing.md` | Test frameworks, coverage, mocking patterns |
| `code-style.md` | Formatting, naming, comments, structure |
| `git-workflow.md` | Commits, branches, PRs, reviews |
| `architecture.md` | Patterns, folder structure, dependencies |
| `api-design.md` | REST/GraphQL conventions, error handling |
| `security.md` | Auth patterns, input validation, secrets |
| `performance.md` | Optimization rules, caching, lazy loading |
**Grouping rules:**
1. Each file should be self-contained for its topic
2. Aim for 3-8 files (not too granular, not too broad)
3. Name files clearly: `{topic}.md`
4. Include only actionable instructions
---
### Phase 4: Create the File Structure
**Output structure:**
```
project-root/
├── CLAUDE.md (or AGENTS.md) # Minimal root with links
└── .claude/ # Or docs/agent-instructions/
├── typescript.md
├── testing.md
├── code-style.md
├── git-workflow.md
└── architecture.md
```
**Root file template:**
```markdown
# Project Name
One-sentence description of the project.
## Quick Reference
- **Package Manager:** pnpm
- **Build:** `pnpm build`
- **Test:** `pnpm test`
- **Typecheck:** `pnpm typecheck`
## Detailed Instructions
For specific guidelines, see:
- [TypeScript Conventions](.claude/typescript.md)
- [Testing Guidelines](.claude/testing.md)
- [Code Style](.claude/code-style.md)
- [Git Workflow](.claude/git-workflow.md)
- [Architecture Patterns](.claude/architecture.md)
```
**Each linked file template:**
```markdown
# {Topic} Guidelines
## Overview
Brief context for when these guidelines apply.
## Rules
### Rule Category 1
- Specific, actionable instruction
- Another specific instruction
### Rule Category 2
- Specific, actionable instruction
## Examples
### Good
\`\`\`typescript
// Example of correct pattern
\`\`\`
### Avoid
\`\`\`typescript
// Example of what not to do
\`\`\`
```
---
### Phase 5: Flag for Deletion
Identify instructions that should be removed entirely.
**Delete if:**
| Criterion | Example | Why Delete |
|-----------|---------|------------|
| Redundant | "Use TypeScript" (in a .ts project) | Agent already knows |
| Too vague | "Write clean code" | Not actionable |
| Overly obvious | "Don't introduce bugs" | Wastes context |
| Default behavior | "Use descriptive variable names" | Standard practice |
| Outdated | References deprecated APIs | No longer applies |
**Output format:**
```markdown
## Flagged for Deletion
| Instruction | Reason |
|-------------|--------|
| "Write clean, maintainable code" | Too vague to be actionable |
| "Use TypeScript" | Redundant - project is already TS |
| "Don't commit secrets" | Agent already knows this |
| "Follow best practices" | Meaningless without specifics |
```
---
## Execution Checklist
```
[ ] Phase 1: All contradictions identified and resolved
[ ] Phase 2: Root file contains ONLY essentials
[ ] Phase 3: All remaining instructions categorized
[ ] Phase 4: File structure created with proper links
[ ] Phase 5: Redundant/vague instructions removed
[ ] Verify: Each linked file is self-contained
[ ] Verify: Root file is under 50 lines
[ ] Verify: All links work correctly
```
---
## Anti-Patterns
| Avoid | Why | Instead |
|-------|-----|---------|
| Keeping everything in root | Bloated, hard to maintain | Split into linked files |
| Too many categories | Fragmentation | Consolidate related topics |
| Vague instructions | Wastes tokens, no value | Be specific or delete |
| Duplicating defaults | Agent already knows | Only override when needed |
| Deep nesting | Hard to navigate | Flat structure with links |
---
## Examples
### Before (Bloated Root)
```markdown
# CLAUDE.md
This is a React project.
## Code Style
- Use 2 spaces
- Use semicolons
- Prefer const over let
- Use arrow functions
... (200 more lines)
## Testing
- Use Jest
- Coverage > 80%
... (100 more lines)
## TypeScript
- Enable strict mode
... (150 more lines)
```
### After (Progressive Disclosure)
```markdown
# CLAUDE.md
React dashboard for real-time analytics visualization.
## Commands
- `pnpm dev` - Start development server
- `pnpm test` - Run tests with coverage
- `pnpm build` - Production build
## Guidelines
- [Code Style](.claude/code-style.md)
- [Testing](.claude/testing.md)
- [TypeScript](.claude/typescript.md)
```
---
## Verification
After refactoring, verify:
1. **Root file is minimal** - Under 50 lines, only universal info
2. **Links work** - All referenced files exist
3. **No contradictions** - Instructions are consistent
4. **Actionable content** - Every instruction is specific
5. **Complete coverage** - No instructions were lost (unless flagged for deletion)
6. **Self-contained files** - Each linked file stands alone

name: astro-cloudflare-deploy
description: Deploy Astro 6 frontend applications to Cloudflare Workers. This skill should be used when deploying an Astro project to Cloudflare, whether as a static site, hybrid rendering, or full SSR. Handles setup of @astrojs/cloudflare adapter, wrangler.jsonc configuration, environment variables, and CI/CD deployment workflows.
---
# Astro 6 to Cloudflare Workers Deployment
## Overview
This skill provides a complete workflow for deploying Astro 6 applications to Cloudflare Workers. It covers static sites, hybrid rendering, and full SSR deployments using the official @astrojs/cloudflare adapter.
**Key Requirements:**
- Astro 6.x (requires Node.js 22.12.0+)
- @astrojs/cloudflare adapter v13+
- Wrangler CLI v4+
## Deployment Decision Tree
First, determine the deployment mode based on project requirements:
```
┌─────────────────────────────────────────────────────────────────┐
│ DEPLOYMENT MODE DECISION │
├─────────────────────────────────────────────────────────────────┤
│ │
│ 1. Static Site? │
│ └─ Marketing sites, blogs, documentation │
│ └─ No server-side rendering needed │
│ └─ Go to: Static Deployment │
│ │
│ 2. Mixed static + dynamic pages? │
│ └─ Some pages need SSR (dashboard, user-specific content) │
│ └─ Most pages are static │
│ └─ Go to: Hybrid Deployment │
│ │
│ 3. All pages need server rendering? │
│ └─ Web app with authentication, dynamic content │
│ └─ Real-time data on all pages │
│ └─ Go to: Full SSR Deployment │
│ │
└─────────────────────────────────────────────────────────────────┘
```
## Step 1: Verify Prerequisites
Before deployment, verify the following:
```bash
# Check Node.js version (must be 22.12.0+)
node --version
# If Node.js is outdated, upgrade to v22 LTS or latest
# Check Astro version
npm list astro
# If upgrading to Astro 6:
npx @astrojs/upgrade@beta
```
**Important:** Astro 6 requires Node.js 22.12.0 or higher. Verify both local and CI/CD environments meet this requirement.
## Step 2: Install Dependencies
Install the Cloudflare adapter and Wrangler:
```bash
# Automated installation (recommended)
npx astro add cloudflare
# Manual installation
npm install @astrojs/cloudflare wrangler --save-dev
```
The automated command will:
- Install `@astrojs/cloudflare`
- Update `astro.config.mjs` with the adapter
- Prompt for deployment mode selection
## Step 3: Configure Astro
Edit `astro.config.mjs` or `astro.config.ts` based on the deployment mode.
### Static Deployment
For purely static sites (no adapter needed):
```javascript
import { defineConfig } from 'astro/config';
export default defineConfig({
output: 'static',
});
```
### Hybrid Deployment (Recommended for Most Projects)
```javascript
import { defineConfig } from 'astro/config';
import cloudflare from '@astrojs/cloudflare';
export default defineConfig({
output: 'hybrid',
adapter: cloudflare({
imageService: 'passthrough', // or 'compile' for optimization
platformProxy: {
enabled: true,
configPath: './wrangler.jsonc',
},
}),
});
```
Mark specific pages for SSR with `export const prerender = false`.
### Full SSR Deployment
```javascript
import { defineConfig } from 'astro/config';
import cloudflare from '@astrojs/cloudflare';
export default defineConfig({
output: 'server',
adapter: cloudflare({
mode: 'directory', // or 'standalone' for single worker
imageService: 'passthrough',
platformProxy: {
enabled: true,
configPath: './wrangler.jsonc',
},
}),
});
```
## Step 4: Create wrangler.jsonc
Cloudflare now recommends `wrangler.jsonc` (JSON with comments) over `wrangler.toml`. Use the template in `assets/wrangler.jsonc` as a starting point.
Key configuration:
```jsonc
{
"$schema": "./node_modules/wrangler/config-schema.json",
"name": "your-app-name",
"compatibility_date": "2025-01-19",
"assets": {
"directory": "./dist",
"binding": "ASSETS"
}
}
```
**Copy the template from:**
```
assets/wrangler-static.jsonc - For static sites
assets/wrangler-hybrid.jsonc - For hybrid rendering
assets/wrangler-ssr.jsonc - For full SSR
```
## Step 5: Configure TypeScript Types
For TypeScript projects, create or update `src/env.d.ts`:
```typescript
/// <reference path="../.astro/types.d.ts" />
interface Env {
// Add your Cloudflare bindings here
MY_KV_NAMESPACE: KVNamespace;
MY_D1_DATABASE: D1Database;
API_URL: string;
}
type Runtime = import('@astrojs/cloudflare').Runtime<Env>;
declare namespace App {
interface Locals extends Runtime {}
}
```
Update `tsconfig.json`:
```json
{
"compilerOptions": {
"types": ["@cloudflare/workers-types"]
}
}
```
## Step 6: Deploy
### Local Development
```bash
# Build the project
npm run build
# Local development with Wrangler
npx wrangler dev
# Remote development (test against production environment)
npx wrangler dev --remote
```
### Production Deployment
```bash
# Deploy to Cloudflare Workers
npx wrangler deploy
# Deploy to specific environment
npx wrangler deploy --env staging
```
### Using GitHub Actions
See `assets/github-actions-deploy.yml` for a complete CI/CD workflow template.
## Step 7: Configure Bindings (Optional)
For advanced features, add bindings in `wrangler.jsonc`:
```jsonc
{
"kv_namespaces": [
{ "binding": "MY_KV", "id": "your-kv-id" }
],
"d1_databases": [
{ "binding": "DB", "database_name": "my-db", "database_id": "your-d1-id" }
],
"r2_buckets": [
{ "binding": "BUCKET", "bucket_name": "my-bucket" }
]
}
```
Access bindings in Astro code:
```javascript
---
const kv = Astro.locals.runtime.env.MY_KV;
const value = await kv.get("key");
---
```
## Environment Variables
### Non-Sensitive Variables
Define in `wrangler.jsonc`:
```jsonc
{
"vars": {
"API_URL": "https://api.example.com",
"ENVIRONMENT": "production"
}
}
```
### Sensitive Secrets
```bash
# Add a secret (encrypted, not stored in config)
npx wrangler secret put API_KEY
# Add environment-specific secret
npx wrangler secret put API_KEY --env staging
# List all secrets
npx wrangler secret list
```
### Local Development Secrets
Create `.dev.vars` (add to `.gitignore`):
```bash
API_KEY=local_dev_key
DATABASE_URL=postgresql://localhost:5432/mydb
```
## Troubleshooting
Refer to `references/troubleshooting.md` for common issues and solutions.
Common problems:
1. **"MessageChannel is not defined"** - React 19 compatibility issue
- Solution: See troubleshooting guide
2. **Build fails with Node.js version error**
- Solution: Upgrade to Node.js 22.12.0+
3. **Styling lost in Astro 6 beta dev mode**
- Solution: Known bug, check GitHub issue status
4. **404 errors on deployment**
- Solution: Check `_routes.json` configuration

# Troubleshooting Guide
This guide covers common issues when deploying Astro 6 to Cloudflare Workers.
## Table of Contents
1. [Build Errors](#build-errors)
2. [Runtime Errors](#runtime-errors)
3. [Deployment Issues](#deployment-issues)
4. [Performance Issues](#performance-issues)
5. [Development Server Issues](#development-server-issues)
---
## Build Errors
### "MessageChannel is not defined"
**Symptoms:**
- Build fails with reference to `MessageChannel`
- Occurs when using React 19 with Cloudflare adapter
**Cause:**
React 19 uses `MessageChannel` which is not available in the Cloudflare Workers runtime by default.
**Solutions:**
1. **Add compatibility flag** in `wrangler.jsonc`:
```jsonc
{
"compatibility_flags": ["nodejs_compat"]
}
```
2. **Use React 18** temporarily if the issue persists:
```bash
npm install react@18 react-dom@18
```
3. **Check for related GitHub issues:**
- [Astro Issue #12824](https://github.com/withastro/astro/issues/12824)
### "Cannot find module '@astrojs/cloudflare'"
**Symptoms:**
- Import error in `astro.config.mjs`
- Type errors in TypeScript
**Solutions:**
1. **Install the adapter:**
```bash
npm install @astrojs/cloudflare
```
2. **Verify installation:**
```bash
npm list @astrojs/cloudflare
```
3. **For Astro 6, ensure v13+:**
```bash
npm install @astrojs/cloudflare@beta
```
### "Too many files for webpack"
**Symptoms:**
- Build fails with file limit error
- Occurs in large projects
**Solution:**
The Cloudflare adapter uses Vite, not webpack. If you see this error, check:
1. **Ensure adapter is properly configured:**
```javascript
// astro.config.mjs
import cloudflare from '@astrojs/cloudflare';
export default defineConfig({
adapter: cloudflare(),
});
```
2. **Check for legacy configuration:**
- Remove any `@astrojs/vercel` or other adapter references
- Ensure `output` mode is set correctly
---
## Runtime Errors
### 404 Errors on Specific Routes
**Symptoms:**
- Some routes return 404 after deployment
- Static assets not found
**Solutions:**
1. **Check `_routes.json` configuration** (for advanced routing):
```json
{
"version": 1,
"include": ["/*"],
"exclude": ["/api/*"]
}
```
2. **Verify build output:**
```bash
npm run build
ls -la dist/
```
3. **Check wrangler.jsonc assets directory:**
```jsonc
{
"assets": {
"directory": "./dist",
"binding": "ASSETS"
}
}
```
### "env is not defined" or "runtime is not defined"
**Symptoms:**
- Cannot access Cloudflare bindings in Astro code
- Runtime errors in server components
**Solutions:**
1. **Ensure TypeScript types are configured:**
```typescript
// src/env.d.ts
type Runtime = import('@astrojs/cloudflare').Runtime<Env>;
declare namespace App {
interface Locals extends Runtime {}
}
```
2. **Access bindings correctly:**
```astro
---
// Correct
const env = Astro.locals.runtime.env;
const kv = env.MY_KV_NAMESPACE;
// Incorrect
const kv = Astro.locals.env.MY_KV_NAMESPACE;
---
```
3. **Verify platformProxy is enabled:**
```javascript
// astro.config.mjs
adapter: cloudflare({
platformProxy: {
enabled: true,
},
})
```
---
## Deployment Issues
### "Authentication required" or "Not logged in"
**Symptoms:**
- `wrangler deploy` fails with authentication error
- CI/CD deployment fails
**Solutions:**
1. **Authenticate locally:**
```bash
npx wrangler login
```
2. **For CI/CD, create API token:**
- Go to Cloudflare Dashboard → My Profile → API Tokens
- Create token with "Edit Cloudflare Workers" template
- Set as `CLOUDFLARE_API_TOKEN` in GitHub/GitLab secrets
3. **Set account ID:**
```bash
# Get account ID
npx wrangler whoami
# Add to wrangler.jsonc or environment
export CLOUDFLARE_ACCOUNT_ID=your-account-id
```
### "Project name already exists"
**Symptoms:**
- Deployment fails due to naming conflict
**Solutions:**
1. **Change project name in wrangler.jsonc:**
```jsonc
{
"name": "my-app-production"
}
```
2. **Or use environments:**
```jsonc
{
"env": {
"staging": {
"name": "my-app-staging"
}
}
}
```
### Deployment succeeds but site doesn't update
**Symptoms:**
- `wrangler deploy` reports success
- Old version still served
**Solutions:**
1. **Clear browser cache** (Ctrl+Shift+R or Cmd+Shift+R)
2. **Verify deployment:**
```bash
npx wrangler deployments list
```
3. **Check for cached versions:**
```bash
npx wrangler versions list
```
4. **Force deployment:**
```bash
npx wrangler deploy --compatibility-date 2025-01-19
```
---
## Performance Issues
### Slow initial page load
**Symptoms:**
- First Contentful Paint (FCP) > 2 seconds
- Large Time to First Byte (TTFB)
**Solutions:**
1. **Use hybrid or static output:**
```javascript
// Pre-render static pages where possible
export const prerender = true;
```
2. **Enable image optimization:**
```javascript
adapter: cloudflare({
imageService: 'compile',
})
```
3. **Cache at edge:**
```javascript
export async function getStaticPaths() {
return [{
params: { id: '1' },
props: { data: await fetchData() },
}];
}
```
### High cold start latency
**Symptoms:**
- First request after inactivity is slow
- Subsequent requests are fast
**Solutions:**
1. **Use mode: 'directory'** for better caching:
```javascript
adapter: cloudflare({
mode: 'directory',
})
```
2. **Keep bundle size small** - avoid heavy dependencies
3. **Use Cloudflare KV** for frequently accessed data:
```javascript
const cached = await env.KV.get('key');
if (!cached) {
const data = await fetch();
await env.KV.put('key', data, { expirationTtl: 3600 });
}
```
---
## Development Server Issues
### Styling not applied in dev mode (Astro 6 Beta)
**Symptoms:**
- CSS not loading in `astro dev`
- Works in production but not locally
**Status:** Known bug in Astro 6 beta
**Workarounds:**
1. **Use production build locally:**
```bash
npm run build
npx wrangler dev --local
```
2. **Check GitHub issue for updates:**
- [Astro Issue #15194](https://github.com/withastro/astro/issues/15194)
### Cannot test bindings locally
**Symptoms:**
- `Astro.locals.runtime.env` is undefined locally
- Cloudflare bindings don't work in dev
**Solutions:**
1. **Ensure platformProxy is enabled:**
```javascript
adapter: cloudflare({
platformProxy: {
enabled: true,
configPath: './wrangler.jsonc',
},
})
```
2. **Create .dev.vars for local secrets:**
```bash
API_KEY=local_key
DATABASE_URL=postgresql://localhost:5432/db
```
3. **Use remote development:**
```bash
npx wrangler dev --remote
```

Vite has been upgraded to Vite 7.0. Check plugin compatibility:
```bash
# Check for outdated plugins
npm outdated
# Update Vite-specific plugins
npm update @vitejs/plugin-react
```
#### 2. Hybrid Output Behavior
The `hybrid` output mode behavior has changed:
```javascript
// Old (Astro 5)
export const prerender = true; // Static
// New (Astro 6) - same, but default behavior changed
// Static is now the default for all pages in hybrid mode
```
#### 3. Development Server
The new dev server runs on the production runtime:
```javascript
// Old: Vite dev server
// New: workerd runtime (same as production)
// Update your code if it relied on Vite-specific behavior
```

## From Other Platforms to Cloudflare
### From Vercel
**Remove Vercel adapter:**
```bash
npm uninstall @astrojs/vercel
```
**Install Cloudflare adapter:**
```bash
npm install @astrojs/cloudflare wrangler --save-dev
```
**Update astro.config.mjs:**
```javascript
// Before
import vercel from '@astrojs/vercel';
export default defineConfig({
adapter: vercel(),
});
// After
import cloudflare from '@astrojs/cloudflare';
export default defineConfig({
adapter: cloudflare(),
});
```
**Update environment variables:**
- Vercel: `process.env.VARIABLE`
- Cloudflare: `Astro.locals.runtime.env.VARIABLE` or `env.VARIABLE` in endpoints
### From Netlify
**Remove Netlify adapter:**
```bash
npm uninstall @astrojs/netlify
```
**Install Cloudflare adapter:**
```bash
npm install @astrojs/cloudflare wrangler --save-dev
```
**Update netlify.toml to wrangler.jsonc:**
```toml
# netlify.toml (old)
[build]
command = "astro build"
publish = "dist"
[functions]
node_bundler = "esbuild"
```
```jsonc
// wrangler.jsonc (new)
{
"name": "my-app",
"compatibility_date": "2025-01-19",
"assets": {
"directory": "./dist"
}
}
```
### From Node.js Server
**Before (Express/Fastify server):**
```javascript
// server.js
import express from 'express';
app.use(express.static('dist'));
app.listen(3000);
```
**After (Cloudflare Workers):**
```javascript
// astro.config.mjs
export default defineConfig({
output: 'server',
adapter: cloudflare(),
});
// Deploy
npx wrangler deploy
```
---
## Adapter Migration
### From Astro 4 to 5/6
**Old adapter syntax:**
```javascript
// Astro 4
adapter: cloudflare({
functionPerRoute: true,
})
```
**New adapter syntax:**
```javascript
// Astro 5/6
adapter: cloudflare({
mode: 'directory', // equivalent to functionPerRoute: true
})
```
### Mode Migration Guide
| Old Option | New Option | Notes |
|------------|------------|-------|
| `functionPerRoute: true` | `mode: 'directory'` | Recommended |
| `functionPerRoute: false` | `mode: 'standalone'` | Single worker |
---
## Breaking Changes
### Removed APIs
1. **`Astro.locals` changes:**
```javascript
// Old
const env = Astro.locals.env;
// New
const env = Astro.locals.runtime.env;
```
2. **Endpoint API changes:**
```javascript
// Old
export async function get({ locals }) {
const { env } = locals;
}
// New
export async function GET({ locals }) {
const env = locals.runtime.env;
}
```
### TypeScript Changes
```typescript
// Old type imports
import type { Runtime } from '@astrojs/cloudflare';
// New type imports
import type { Runtime } from '@astrojs/cloudflare/virtual';
// Or use the adapter export
import cloudflare from '@astrojs/cloudflare';
type Runtime = typeof cloudflare.Runtime;
```
---
## Rollback Procedures
### If Deployment Fails
1. **Keep old version deployed:**
```bash
npx wrangler versions list
npx wrangler versions rollback <version-id>
```
2. **Or rollback git changes:**
```bash
git revert HEAD
npx wrangler deploy
```
### If Build Fails
1. **Clear cache:**
```bash
rm -rf node_modules .astro dist
npm install
npm run build
```
2. **Check for incompatible dependencies:**
```bash
npm ls
```
3. **Temporarily pin to previous version:**
```bash
npm install astro@5
npm install @astrojs/cloudflare@12
```

# Astro Usage Guide
**Always consult [docs.astro.build](https://docs.astro.build) for code examples and latest API.**
Astro is the web framework for content-driven websites.
---
## Quick Reference
### File Location
CLI looks for `astro.config.js`, `astro.config.mjs`, `astro.config.cjs`, and `astro.config.ts` in: `./`. Use `--config` for custom path.
### CLI Commands
- `npx astro dev` - Start the development server.
- `npx astro build` - Build your project and write it to disk.
- `npx astro check` - Check your project for errors.
- `npx astro add` - Add an integration.
- `npmx astro sync` - Generate TypeScript types for all Astro modules.
**Re-run after adding/changing plugins.**
### Project Structure
Astro leverages an opinionated folder layout for your project. Every Astro project root should include some directories and files. Reference [project structure docs](https://docs.astro.build/en/basics/project-structure).
- `src/*` - Your project source code (components, pages, styles, images, etc.)
- `src/pages` - Required sub-directory in your Astro project. Without it, your site will have no pages or routes!
- `src/components` - It is common to group and organize all of your project components together in this folder. This is a common convention in Astro projects, but it is not required. Feel free to organize your components however you like!
- `src/layouts` - Just like `src/components`, this directory is a common convention but not required.
- `src/styles` - It is a common convention to store your CSS or Sass files here, but this is not required. As long as your styles live somewhere in the src/ directory and are imported correctly, Astro will handle and optimize them.
- `public/*` - Your non-code, unprocessed assets (fonts, icons, etc.). The files in this folder will be copied into the build folder untouched, and then your site will be built.
- `package.json` - A project manifest.
- `astro.config.{js,mjs,cjs,ts}` - An Astro configuration file. (recommended)
- `tsconfig.json` - A TypeScript configuration file. (recommended)
---
## Core Config Options
| Option | Notes |
|--------|-------|
| `site` | Your final, deployed URL. Astro uses this full URL to generate your sitemap and canonical URLs in your final build. |
---
## Adapters
Deploy to your favorite server, serverless, or edge host with build adapters. Use an adapter to enable on-demand rendering in your Astro project.
**Add [Node.js](https://docs.astro.build/en/guides/integrations-guide/node) adapter using astro add:**
```
npx astro add node --yes
```
**Add [Cloudflare](https://docs.astro.build/en/guides/integrations-guide/cloudflare) adapter using astro add:**
```
npx astro add cloudflare --yes
```
**Add [Netlify](https://docs.astro.build/en/guides/integrations-guide/netlify) adapter using astro add:**
```
npx astro add netlify --yes
```
**Add [Vercel](https://docs.astro.build/en/guides/integrations-guide/vercel) adapter using astro add:**
```
npx astro add vercel --yes
```

name: Confidence Check
description: Pre-implementation confidence assessment (≥90% required). Use before starting any implementation to verify readiness with duplicate check, architecture compliance, official docs verification, OSS references, and root cause identification.
allowed-tools: Read, Grep, Glob, WebFetch, WebSearch
---
# Confidence Check Skill
## Purpose
Prevents wrong-direction execution by assessing confidence **BEFORE** starting implementation.
**Requirement**: ≥90% confidence to proceed with implementation.
**Test Results** (2025-10-21):
- Precision: 1.000 (no false positives)
- Recall: 1.000 (no false negatives)
- 8/8 test cases passed
## When to Use
Use this skill BEFORE implementing any task to ensure:
- No duplicate implementations exist
- Architecture compliance verified
- Official documentation reviewed
- Working OSS implementations found
- Root cause properly identified
## Confidence Assessment Criteria
Calculate confidence score (0.0 - 1.0) based on 5 checks:
### 1. No Duplicate Implementations? (25%)
**Check**: Search codebase for existing functionality
```bash
# Use Grep to search for similar functions
# Use Glob to find related modules
```
✅ Pass if no duplicates found
❌ Fail if similar implementation exists
### 2. Architecture Compliance? (25%)
**Check**: Verify tech stack alignment
- Read `CLAUDE.md`, `PLANNING.md`
- Confirm existing patterns used
- Avoid reinventing existing solutions
✅ Pass if uses existing tech stack (e.g., Supabase, UV, pytest)
❌ Fail if introduces new dependencies unnecessarily
### 3. Official Documentation Verified? (20%)
**Check**: Review official docs before implementation
- Use Context7 MCP for official docs
- Use WebFetch for documentation URLs
- Verify API compatibility
✅ Pass if official docs reviewed
❌ Fail if relying on assumptions
### 4. Working OSS Implementations Referenced? (15%)
**Check**: Find proven implementations
- Use Tavily MCP or WebSearch
- Search GitHub for examples
- Verify working code samples
✅ Pass if OSS reference found
❌ Fail if no working examples
### 5. Root Cause Identified? (15%)
**Check**: Understand the actual problem
- Analyze error messages
- Check logs and stack traces
- Identify underlying issue
✅ Pass if root cause clear
❌ Fail if symptoms unclear
## Confidence Score Calculation
```
Total = Check1 (25%) + Check2 (25%) + Check3 (20%) + Check4 (15%) + Check5 (15%)
If Total >= 0.90: ✅ Proceed with implementation
If Total >= 0.70: ⚠️ Present alternatives, ask questions
If Total < 0.70: ❌ STOP - Request more context
```
## Output Format
```
📋 Confidence Checks:
✅ No duplicate implementations found
✅ Uses existing tech stack
✅ Official documentation verified
✅ Working OSS implementation found
✅ Root cause identified
📊 Confidence: 1.00 (100%)
✅ High confidence - Proceeding to implementation
```
## Implementation Details
The TypeScript implementation is available in `confidence.ts` for reference, containing:
- `confidenceCheck(context)` - Main assessment function
- Detailed check implementations
- Context interface definitions
## ROI
**Token Savings**: Spend 100-200 tokens on confidence check to save 5,000-50,000 tokens on wrong-direction work.
**Success Rate**: 100% precision and recall in production testing.

description: Analyze Stitch projects and synthesize a semantic design system into DESIGN.md files
allowed-tools:

- "Read"
- "Write"
- "web_fetch"
---
# Stitch DESIGN.md Skill
You are an expert Design Systems Lead. Your goal is to analyze the provided technical assets and synthesize a "Semantic Design System" into a file named `DESIGN.md`.
## Overview
This skill helps you create `DESIGN.md` files that serve as the "source of truth" for prompting Stitch to generate new screens that align perfectly with existing design language. Stitch interprets design through "Visual Descriptions" supported by specific color values.
## Prerequisites
- Access to the Stitch MCP Server
- A Stitch project with at least one designed screen
- Access to the Stitch Effective Prompting Guide: https://stitch.withgoogle.com/docs/learn/prompting/
## The Goal
The `DESIGN.md` file will serve as the "source of truth" for prompting Stitch to generate new screens that align perfectly with the existing design language. Stitch interprets design through "Visual Descriptions" supported by specific color values.
## Retrieval and Networking
To analyze a Stitch project, you must retrieve screen metadata and design assets using the Stitch MCP Server tools:
1. **Namespace discovery**: Run `list_tools` to find the Stitch MCP prefix. Use this prefix (e.g., `mcp_stitch:`) for all subsequent calls.
2. **Project lookup** (if Project ID is not provided):
- Call `[prefix]:list_projects` with `filter: "view=owned"` to retrieve all user projects
- Identify the target project by title or URL pattern
- Extract the Project ID from the `name` field (e.g., `projects/13534454087919359824`)
3. **Screen lookup** (if Screen ID is not provided):
- Call `[prefix]:list_screens` with the `projectId` (just the numeric ID, not the full path)
- Review screen titles to identify the target screen (e.g., "Home", "Landing Page")
- Extract the Screen ID from the screen's `name` field
4. **Metadata fetch**:
- Call `[prefix]:get_screen` with both `projectId` and `screenId` (both as numeric IDs only)
- This returns the complete screen object including:
- `screenshot.downloadUrl` - Visual reference of the design
- `htmlCode.downloadUrl` - Full HTML/CSS source code
- `width`, `height`, `deviceType` - Screen dimensions and target platform
- Project metadata including `designTheme` with color and style information
5. **Asset download**:
- Use `web_fetch` or `read_url_content` to download the HTML code from `htmlCode.downloadUrl`
- Optionally download the screenshot from `screenshot.downloadUrl` for visual reference
- Parse the HTML to extract Tailwind classes, custom CSS, and component patterns
6. **Project metadata extraction**:
- Call `[prefix]:get_project` with the project `name` (full path: `projects/{id}`) to get:
- `designTheme` object with color mode, fonts, roundness, custom colors
- Project-level design guidelines and descriptions
- Device type preferences and layout principles
## Analysis & Synthesis Instructions
### 1. Extract Project Identity (JSON)
- Locate the Project Title
- Locate the specific Project ID (e.g., from the `name` field in the JSON)
### 2. Define the Atmosphere (Image/HTML)
Evaluate the screenshot and HTML structure to capture the overall "vibe." Use evocative adjectives to describe the mood (e.g., "Airy," "Dense," "Minimalist," "Utilitarian").
### 3. Map the Color Palette (Tailwind Config/JSON)
Identify the key colors in the system. For each color, provide:
- A descriptive, natural language name that conveys its character (e.g., "Deep Muted Teal-Navy")
- The specific hex code in parentheses for precision (e.g., "#294056")
- Its specific functional role (e.g., "Used for primary actions")
### 4. Translate Geometry & Shape (CSS/Tailwind)
Convert technical `border-radius` and layout values into physical descriptions:
- Describe `rounded-full` as "Pill-shaped"
- Describe `rounded-lg` as "Subtly rounded corners"
- Describe `rounded-none` as "Sharp, squared-off edges"
### 5. Describe Depth & Elevation
Explain how the UI handles layers. Describe the presence and quality of shadows (e.g., "Flat," "Whisper-soft diffused shadows," or "Heavy, high-contrast drop shadows").
## Output Guidelines
- **Language:** Use descriptive design terminology and natural language exclusively
- **Format:** Generate a clean Markdown file following the structure below
- **Precision:** Include exact hex codes for colors while using descriptive names
- **Context:** Explain the "why" behind design decisions, not just the "what"
## Output Format (DESIGN.md Structure)
```markdown
# Design System: [Project Title]
**Project ID:** [Insert Project ID Here]
## 1. Visual Theme & Atmosphere
(Description of the mood, density, and aesthetic philosophy.)
## 2. Color Palette & Roles
(List colors by Descriptive Name + Hex Code + Functional Role.)
## 3. Typography Rules
(Description of font family, weight usage for headers vs. body, and letter-spacing character.)
## 4. Component Stylings
* **Buttons:** (Shape description, color assignment, behavior).
* **Cards/Containers:** (Corner roundness description, background color, shadow depth).
* **Inputs/Forms:** (Stroke style, background).
## 5. Layout Principles
(Description of whitespace strategy, margins, and grid alignment.)
```
## Usage Example
To use this skill for the Furniture Collection project:
1. **Retrieve project information:**
```
Use the Stitch MCP Server to get the Furniture Collection project
```
2. **Get the Home page screen details:**
```
Retrieve the Home page screen's code, image, and screen object information
```
3. **Reference best practices:**
```
Review the Stitch Effective Prompting Guide at:
https://stitch.withgoogle.com/docs/learn/prompting/
```
4. **Analyze and synthesize:**
- Extract all relevant design tokens from the screen
- Translate technical values into descriptive language
- Organize information according to the DESIGN.md structure
5. **Generate the file:**
- Create `DESIGN.md` in the project directory
- Follow the prescribed format exactly
- Ensure all color codes are accurate
- Use evocative, designer-friendly language
## Best Practices
- **Be Descriptive:** Avoid generic terms like "blue" or "rounded." Use "Ocean-deep Cerulean (#0077B6)" or "Gently curved edges"
- **Be Functional:** Always explain what each design element is used for
- **Be Consistent:** Use the same terminology throughout the document
- **Be Visual:** Help readers visualize the design through your descriptions
- **Be Precise:** Include exact values (hex codes, pixel values) in parentheses after natural language descriptions
## Tips for Success
1. **Start with the big picture:** Understand the overall aesthetic before diving into details
2. **Look for patterns:** Identify consistent spacing, sizing, and styling patterns
3. **Think semantically:** Name colors by their purpose, not just their appearance
4. **Consider hierarchy:** Document how visual weight and importance are communicated
5. **Reference the guide:** Use language and patterns from the Stitch Effective Prompting Guide
## Common Pitfalls to Avoid
- ❌ Using technical jargon without translation (e.g., "rounded-xl" instead of "generously rounded corners")
- ❌ Omitting color codes or using only descriptive names
- ❌ Forgetting to explain functional roles of design elements
- ❌ Being too vague in atmosphere descriptions
- ❌ Ignoring subtle design details like shadows or spacing patterns

# Design System: Furniture Collections List
**Project ID:** 13534454087919359824
## 1. Visual Theme & Atmosphere
The Furniture Collections List embodies a **sophisticated, minimalist sanctuary** that marries the pristine simplicity of Scandinavian design with the refined visual language of luxury editorial presentation. The interface feels **spacious and tranquil**, prioritizing breathing room and visual clarity above all else. The design philosophy is gallery-like and photography-first, allowing each furniture piece to command attention as an individual art object.
The overall mood is **airy yet grounded**, creating an aspirational aesthetic that remains approachable and welcoming. The interface feels **utilitarian in its restraint** but elegant in its execution, with every element serving a clear purpose while maintaining visual sophistication. The atmosphere evokes the serene ambiance of a high-end furniture showroom where customers can browse thoughtfully without visual overwhelm.
**Key Characteristics:**
- Expansive whitespace creating generous breathing room between elements
- Clean, architectural grid system with structured content blocks
- Photography-first presentation with minimal UI interference
- Whisper-soft visual hierarchy that guides without shouting
- Refined, understated interactive elements
- Professional yet inviting editorial tone
## 2. Color Palette & Roles
### Primary Foundation
- **Warm Barely-There Cream** (#FCFAFA) Primary background color. Creates an almost imperceptible warmth that feels more inviting than pure white, serving as the serene canvas for the entire experience.
- **Crisp Very Light Gray** (#F5F5F5) Secondary surface color used for card backgrounds and content areas. Provides subtle visual separation while maintaining the airy, ethereal quality.
### Accent & Interactive
- **Deep Muted Teal-Navy** (#294056) The sole vibrant accent in the palette. Used exclusively for primary call-to-action buttons (e.g., "Shop Now", "View all products"), active navigation links, selected filter states, and subtle interaction highlights. This sophisticated anchor color creates visual focus points without disrupting the serene neutral foundation.
### Typography & Text Hierarchy
- **Charcoal Near-Black** (#2C2C2C) Primary text color for headlines and product names. Provides strong readable contrast while being softer and more refined than pure black.
- **Soft Warm Gray** (#6B6B6B) Secondary text used for body copy, product descriptions, and supporting metadata. Creates clear typographic hierarchy without harsh contrast.
- **Ultra-Soft Silver Gray** (#E0E0E0) Tertiary color for borders, dividers, and subtle structural elements. Creates separation so gentle it's almost imperceptible.
### Functional States (Reserved for system feedback)
- **Success Moss** (#10B981) Stock availability, confirmation states, positive indicators
- **Alert Terracotta** (#EF4444) Low stock warnings, error states, critical alerts
- **Informational Slate** (#64748B) Neutral system messages, informational callouts
## 3. Typography Rules
**Primary Font Family:** Manrope
**Character:** Modern, geometric sans-serif with gentle humanist warmth. Slightly rounded letterforms that feel contemporary yet approachable.
### Hierarchy & Weights
- **Display Headlines (H1):** Semi-bold weight (600), generous letter-spacing (0.02em for elegance), 2.75-3.5rem size. Used sparingly for hero sections and major page titles.
- **Section Headers (H2):** Semi-bold weight (600), subtle letter-spacing (0.01em), 2-2.5rem size. Establishes clear content zones and featured collections.
- **Subsection Headers (H3):** Medium weight (500), normal letter-spacing, 1.5-1.75rem size. Product names and category labels.
- **Body Text:** Regular weight (400), relaxed line-height (1.7), 1rem size. Descriptions and supporting content prioritize comfortable readability.
- **Small Text/Meta:** Regular weight (400), slightly tighter line-height (1.5), 0.875rem size. Prices, availability, and metadata remain legible but visually recessive.
- **CTA Buttons:** Medium weight (500), subtle letter-spacing (0.01em), 1rem size. Balanced presence without visual aggression.
### Spacing Principles
- Headers use slightly expanded letter-spacing for refined elegance
- Body text maintains generous line-height (1.7) for effortless reading
- Consistent vertical rhythm with 2-3rem between related text blocks
- Large margins (4-6rem) between major sections to reinforce spaciousness
## 4. Component Stylings
### Buttons
- **Shape:** Subtly rounded corners (8px/0.5rem radius) approachable and modern without appearing playful or childish
- **Primary CTA:** Deep Muted Teal-Navy (#294056) background with pure white text, comfortable padding (0.875rem vertical, 2rem horizontal)
- **Hover State:** Subtle darkening to deeper navy, smooth 250ms ease-in-out transition
- **Focus State:** Soft outer glow in the primary color for keyboard navigation accessibility
- **Secondary CTA (if needed):** Outlined style with Deep Muted Teal-Navy border, transparent background, hover fills with whisper-soft teal tint
### Cards & Product Containers
- **Corner Style:** Gently rounded corners (12px/0.75rem radius) creating soft, refined edges
- **Background:** Alternates between Warm Barely-There Cream and Crisp Very Light Gray based on layering needs
- **Shadow Strategy:** Flat by default. On hover, whisper-soft diffused shadow appears (`0 2px 8px rgba(0,0,0,0.06)`) creating subtle depth
- **Border:** Optional hairline border (1px) in Ultra-Soft Silver Gray for delicate definition when shadows aren't present
- **Internal Padding:** Generous 2-2.5rem creating comfortable breathing room for content
- **Image Treatment:** Full-bleed at the top of cards, square or 4:3 ratio, seamless edge-to-edge presentation
### Navigation
- **Style:** Clean horizontal layout with generous spacing (2-3rem) between menu items
- **Typography:** Medium weight (500), subtle uppercase, expanded letter-spacing (0.06em) for refined sophistication
- **Default State:** Charcoal Near-Black text
- **Active/Hover State:** Smooth 200ms color transition to Deep Muted Teal-Navy
- **Active Indicator:** Thin underline (2px) in Deep Muted Teal-Navy appearing below current section
- **Mobile:** Converts to elegant hamburger menu with sliding drawer
### Inputs & Forms
- **Stroke Style:** Refined 1px border in Soft Warm Gray
- **Background:** Warm Barely-There Cream with transition to Crisp Very Light Gray on focus
- **Corner Style:** Matching button roundness (8px/0.5rem) for visual consistency
- **Focus State:** Border color shifts to Deep Muted Teal-Navy with subtle outer glow
- **Padding:** Comfortable 0.875rem vertical, 1.25rem horizontal for touch-friendly targets
- **Placeholder Text:** Ultra-Soft Silver Gray, elegant and unobtrusive
### Product Cards (Specific Pattern)
- **Image Area:** Square (1:1) or landscape (4:3) ratio filling card width completely
- **Content Stack:** Product name (H3), brief descriptor, material/finish, price
- **Price Display:** Emphasized with semi-bold weight (600) in Charcoal Near-Black
- **Hover Behavior:** Gentle lift effect (translateY -4px) combined with enhanced shadow
- **Spacing:** Consistent 1.5rem internal padding below image
## 5. Layout Principles
### Grid & Structure
- **Max Content Width:** 1440px for optimal readability and visual balance on large displays
- **Grid System:** Responsive 12-column grid with fluid gutters (24px mobile, 32px desktop)
- **Product Grid:** 4 columns on large desktop, 3 on desktop, 2 on tablet, 1 on mobile
- **Breakpoints:**
- Mobile: <768px
- Tablet: 768-1024px
- Desktop: 1024-1440px
- Large Desktop: >1440px
### Whitespace Strategy (Critical to the Design)
- **Base Unit:** 8px for micro-spacing, 16px for component spacing
- **Vertical Rhythm:** Consistent 2rem (32px) base unit between related elements
- **Section Margins:** Generous 5-8rem (80-128px) between major sections creating dramatic breathing room
- **Edge Padding:** 1.5rem (24px) mobile, 3rem (48px) tablet/desktop for comfortable framing
- **Hero Sections:** Extra-generous top/bottom padding (8-12rem) for impactful presentation
### Alignment & Visual Balance
- **Text Alignment:** Left-aligned for body and navigation (optimal readability), centered for hero headlines and featured content
- **Image to Text Ratio:** Heavily weighted toward imagery (70-30 split) reinforcing photography-first philosophy
- **Asymmetric Balance:** Large hero images offset by compact, refined text blocks
- **Visual Weight Distribution:** Strategic use of whitespace to draw eyes to hero products and primary CTAs
- **Reading Flow:** Clear top-to-bottom, left-to-right pattern with intentional focal points
### Responsive Behavior & Touch
- **Mobile-First Foundation:** Core experience designed and perfected for smallest screens first
- **Progressive Enhancement:** Additional columns, imagery, and details added gracefully at larger breakpoints
- **Touch Targets:** Minimum 44x44px for all interactive elements (WCAG AAA compliant)
- **Image Optimization:** Responsive images with appropriate resolutions for each breakpoint, lazy-loading for performance
- **Collapsing Strategy:** Navigation collapses to hamburger, grid reduces columns, padding scales proportionally
## 6. Design System Notes for Stitch Generation
When creating new screens for this project using Stitch, reference these specific instructions:
### Language to Use
- **Atmosphere:** "Sophisticated minimalist sanctuary with gallery-like spaciousness"
- **Button Shapes:** "Subtly rounded corners" (not "rounded-md" or "8px")
- **Shadows:** "Whisper-soft diffused shadows on hover" (not "shadow-sm")
- **Spacing:** "Generous breathing room" and "expansive whitespace"
### Color References
Always use the descriptive names with hex codes:
- Primary CTA: "Deep Muted Teal-Navy (#294056)"
- Backgrounds: "Warm Barely-There Cream (#FCFAFA)" or "Crisp Very Light Gray (#F5F5F5)"
- Text: "Charcoal Near-Black (#2C2C2C)" or "Soft Warm Gray (#6B6B6B)"
### Component Prompts
- "Create a product card with gently rounded corners, full-bleed square product image, and whisper-soft shadow on hover"
- "Design a primary call-to-action button in Deep Muted Teal-Navy (#294056) with subtle rounded corners and comfortable padding"
- "Add a navigation bar with generous spacing between items, using medium-weight Manrope with subtle uppercase and expanded letter-spacing"
### Incremental Iteration
When refining existing screens:
1. Focus on ONE component at a time (e.g., "Update the product grid cards")
2. Be specific about what to change (e.g., "Increase the internal padding of product cards from 1.5rem to 2rem")
3. Reference this design system language consistently

name: docker-optimizer
description: Reviews Dockerfiles for best practices, security issues, and image size optimizations including multi-stage builds and layer caching. Use when working with Docker, containers, or deployment.
allowed-tools: Read, Grep, Glob, Write, Edit
---
# Docker Optimizer
Analyzes and optimizes Dockerfiles for performance, security, and best practices.
## When to Use
- User working with Docker or containers
- Dockerfile optimization needed
- Container image too large
- User mentions "Docker", "container", "image size", or "deployment"
## Instructions
### 1. Find Dockerfiles
Search for: `Dockerfile`, `Dockerfile.*`, `*.dockerfile`
### 2. Check Best Practices
**Use specific base image versions:**
```dockerfile
# Bad
FROM node:latest
# Good
FROM node:18-alpine
```
**Minimize layers:**
```dockerfile
# Bad
RUN apt-get update
RUN apt-get install -y curl
RUN apt-get install -y git
# Good
RUN apt-get update && \
apt-get install -y curl git && \
rm -rf /var/lib/apt/lists/*
```
**Order instructions by change frequency:**
```dockerfile
# Dependencies change less than code
COPY package*.json ./
RUN npm install
COPY . .
```
**Use .dockerignore:**
```
node_modules
.git
.env
*.md
```
### 3. Multi-Stage Builds
Reduce final image size:
```dockerfile
# Build stage
FROM node:18 AS build
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build
# Production stage
FROM node:18-alpine
WORKDIR /app
COPY --from=build /app/dist ./dist
COPY --from=build /app/node_modules ./node_modules
CMD ["node", "dist/index.js"]
```
### 4. Security Issues
**Don't run as root:**
```dockerfile
RUN addgroup -S appgroup && adduser -S appuser -G appgroup
USER appuser
```
**No secrets in image:**
```dockerfile
# Bad: Hardcoded secret
ENV API_KEY=secret123
# Good: Use build args or runtime env
ARG BUILD_ENV
ENV NODE_ENV=${BUILD_ENV}
```
**Scan for vulnerabilities:**
```bash
docker scan image:tag
trivy image image:tag
```
### 5. Size Optimization
**Use Alpine images:**
- `node:18-alpine` vs `node:18` (900MB → 170MB)
- `python:3.11-alpine` vs `python:3.11` (900MB → 50MB)
**Remove unnecessary files:**
```dockerfile
RUN npm install --production && \
npm cache clean --force
```
**Use specific COPY:**
```dockerfile
# Bad: Copies everything
COPY . .
# Good: Copy only what's needed
COPY package*.json ./
COPY src ./src
```
### 6. Caching Strategy
Layer caching optimization:
```dockerfile
# Install dependencies first (cached if package.json unchanged)
COPY package*.json ./
RUN npm install
# Copy source (changes more frequently)
COPY . .
RUN npm run build
```
### 7. Health Checks
```dockerfile
HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
CMD node healthcheck.js
```
### 8. Generate Optimized Dockerfile
Provide improved version with:
- Multi-stage build
- Appropriate base image
- Security improvements
- Layer optimization
- Build caching
- .dockerignore file
### 9. Build Commands
**Efficient build:**
```bash
# Use BuildKit
DOCKER_BUILDKIT=1 docker build -t app:latest .
# Build with cache from registry
docker build --cache-from myregistry/app:latest -t app:latest .
```
### 10. Dockerfile Checklist
- [ ] Specific base image tag (not `latest`)
- [ ] Multi-stage build if applicable
- [ ] Non-root user
- [ ] Minimal layers (combined RUN commands)
- [ ] .dockerignore present
- [ ] No secrets in image
- [ ] Proper layer ordering for caching
- [ ] Alpine or slim variant used
- [ ] Cleanup in same RUN layer
- [ ] HEALTHCHECK defined
## Security Best Practices
- Scan images regularly
- Use official base images
- Keep base images updated
- Minimize attack surface (fewer packages)
- Run as non-root user
- Use read-only filesystem where possible
## Supporting Files
- `templates/Dockerfile.optimized`: Optimized multi-stage Dockerfile example

name: git-commit
description: Use when creating git commits to ensure commit messages follow project standards. Applies the 7 rules for great commit messages with focus on conciseness and imperative mood.
---
# Git Commit Guidelines
Follow these rules when creating commits for this repository.
## The 7 Rules
1. **Separate subject from body with a blank line**
2. **Limit the subject line to 50 characters**
3. **Capitalize the subject line**
4. **Do not end the subject line with a period**
5. **Use the imperative mood** ("Add feature" not "Added feature")
6. **Wrap the body at 72 characters**
7. **Use the body to explain what and why vs. how**
## Key Principles
**Be concise, not verbose.** Every word should add value. Avoid unnecessary details about implementation mechanics - focus on what changed and why it matters.
**Subject line should stand alone** - don't require reading the body to understand the change. Body is optional and only needed for non-obvious context.
**Focus on the change, not how it was discovered** - never reference "review feedback", "PR comments", or "code review" in commit messages. Describe what the change does and why, not that someone asked for it.
**Avoid bullet points** - write prose, not lists. If you need bullets to explain a change, you're either committing too much at once or over-explaining implementation details.
## Format
Always use a HEREDOC to ensure proper formatting:
```bash
git commit -m "$(cat <<'EOF'
Subject line here
Optional body paragraph explaining what and why.
EOF
)"
```
## Good Examples
```
Add session isolation for concurrent executions
```
```
Fix encoding parameter handling in file operations
The encoding parameter wasn't properly passed through the validation
layer, causing base64 content to be treated as UTF-8.
```
## Bad Examples
```
Update files
Changes some things related to sessions and also fixes a bug.
```
Problem: Vague subject, doesn't explain what changed
```
Add file operations support
Implements FileClient with read/write methods and adds FileService
in the container with a validation layer. Includes comprehensive test
coverage for edge cases and supports both UTF-8 text and base64 binary
encodings. Uses proper error handling with custom error types from the
shared package for consistency across the SDK.
```
Problem: Over-explains implementation details, uses too many words
## Checklist Before Committing
- [ ] Subject is ≤50 characters
- [ ] Subject uses imperative mood
- [ ] Subject is capitalized, no period at end
- [ ] Body (if present) explains why, not how
- [ ] No references to review feedback or PR comments
- [ ] No bullet points in body
- [ ] Not committing sensitive files (.env, credentials)

# Skill Creator
This skill provides guidance for creating effective skills.
## About Skills
Skills are modular, self-contained packages that extend Claude's capabilities by providing
specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific
domains or tasks—they transform Claude from a general-purpose agent into a specialized agent
equipped with procedural knowledge that no model can fully possess.
### What Skills Provide
1. Specialized workflows - Multi-step procedures for specific domains
2. Tool integrations - Instructions for working with specific file formats or APIs
3. Domain expertise - Company-specific knowledge, schemas, business logic
4. Bundled resources - Scripts, references, and assets for complex and repetitive tasks
## Core Principles
### Concise is Key
The context window is a public good. Skills share the context window with everything else Claude needs: system prompt, conversation history, other Skills' metadata, and the actual user request.
**Default assumption: Claude is already very smart.** Only add context Claude doesn't already have. Challenge each piece of information: "Does Claude really need this explanation?" and "Does this paragraph justify its token cost?"
Prefer concise examples over verbose explanations.
### Set Appropriate Degrees of Freedom
Match the level of specificity to the task's fragility and variability:
**High freedom (text-based instructions)**: Use when multiple approaches are valid, decisions depend on context, or heuristics guide the approach.
**Medium freedom (pseudocode or scripts with parameters)**: Use when a preferred pattern exists, some variation is acceptable, or configuration affects behavior.
**Low freedom (specific scripts, few parameters)**: Use when operations are fragile and error-prone, consistency is critical, or a specific sequence must be followed.
Think of Claude as exploring a path: a narrow bridge with cliffs needs specific guardrails (low freedom), while an open field allows many routes (high freedom).
### Anatomy of a Skill
Every skill consists of a required SKILL.md file and optional bundled resources:
```
skill-name/
├── SKILL.md (required)
│ ├── YAML frontmatter metadata (required)
│ │ ├── name: (required)
│ │ └── description: (required)
│ └── Markdown instructions (required)
└── Bundled Resources (optional)
├── scripts/ - Executable code (Python/Bash/etc.)
├── references/ - Documentation intended to be loaded into context as needed
└── assets/ - Files used in output (templates, icons, fonts, etc.)
```
#### SKILL.md (required)
Every SKILL.md consists of:
- **Frontmatter** (YAML): Contains `name` and `description` fields. These are the only fields that Claude reads to determine when the skill gets used, thus it is very important to be clear and comprehensive in describing what the skill is, and when it should be used.
- **Body** (Markdown): Instructions and guidance for using the skill. Only loaded AFTER the skill triggers (if at all).
#### Bundled Resources (optional)
##### Scripts (`scripts/`)
Executable code (Python/Bash/etc.) for tasks that require deterministic reliability or are repeatedly rewritten.
- **When to include**: When the same code is being rewritten repeatedly or deterministic reliability is needed
- **Example**: `scripts/rotate_pdf.py` for PDF rotation tasks
- **Benefits**: Token efficient, deterministic, may be executed without loading into context
- **Note**: Scripts may still need to be read by Claude for patching or environment-specific adjustments
##### References (`references/`)
Documentation and reference material intended to be loaded as needed into context to inform Claude's process and thinking.
- **When to include**: For documentation that Claude should reference while working
- **Examples**: `references/finance.md` for financial schemas, `references/mnda.md` for company NDA template, `references/policies.md` for company policies, `references/api_docs.md` for API specifications
- **Use cases**: Database schemas, API documentation, domain knowledge, company policies, detailed workflow guides
- **Benefits**: Keeps SKILL.md lean, loaded only when Claude determines it's needed
- **Best practice**: If files are large (>10k words), include grep search patterns in SKILL.md
- **Avoid duplication**: Information should live in either SKILL.md or references files, not both. Prefer references files for detailed information unless it's truly core to the skill—this keeps SKILL.md lean while making information discoverable without hogging the context window. Keep only essential procedural instructions and workflow guidance in SKILL.md; move detailed reference material, schemas, and examples to references files.
##### Assets (`assets/`)
Files not intended to be loaded into context, but rather used within the output Claude produces.
- **When to include**: When the skill needs files that will be used in the final output
- **Examples**: `assets/logo.png` for brand assets, `assets/slides.pptx` for PowerPoint templates, `assets/frontend-template/` for HTML/React boilerplate, `assets/font.ttf` for typography
- **Use cases**: Templates, images, icons, boilerplate code, fonts, sample documents that get copied or modified
- **Benefits**: Separates output resources from documentation, enables Claude to use files without loading them into context
#### What to Not Include in a Skill
A skill should only contain essential files that directly support its functionality. Do NOT create extraneous documentation or auxiliary files, including:
- README.md
- INSTALLATION_GUIDE.md
- QUICK_REFERENCE.md
- CHANGELOG.md
- etc.
The skill should only contain the information needed for an AI agent to do the job at hand. It should not contain auxilary context about the process that went into creating it, setup and testing procedures, user-facing documentation, etc. Creating additional documentation files just adds clutter and confusion.
### Progressive Disclosure Design Principle
Skills use a three-level loading system to manage context efficiently:
1. **Metadata (name + description)** - Always in context (~100 words)
2. **SKILL.md body** - When skill triggers (<5k words)
3. **Bundled resources** - As needed by Claude (Unlimited because scripts can be executed without reading into context window)
#### Progressive Disclosure Patterns
Keep SKILL.md body to the essentials and under 500 lines to minimize context bloat. Split content into separate files when approaching this limit. When splitting out content into other files, it is very important to reference them from SKILL.md and describe clearly when to read them, to ensure the reader of the skill knows they exist and when to use them.
**Key principle:** When a skill supports multiple variations, frameworks, or options, keep only the core workflow and selection guidance in SKILL.md. Move variant-specific details (patterns, examples, configuration) into separate reference files.
**Pattern 1: High-level guide with references**
```markdown
# PDF Processing
## Quick start
Extract text with pdfplumber:
[code example]
## Advanced features
- **Form filling**: See [FORMS.md](FORMS.md) for complete guide
- **API reference**: See [REFERENCE.md](REFERENCE.md) for all methods
- **Examples**: See [EXAMPLES.md](EXAMPLES.md) for common patterns
```
Claude loads FORMS.md, REFERENCE.md, or EXAMPLES.md only when needed.
**Pattern 2: Domain-specific organization**
For Skills with multiple domains, organize content by domain to avoid loading irrelevant context:
```
bigquery-skill/
├── SKILL.md (overview and navigation)
└── reference/
├── finance.md (revenue, billing metrics)
├── sales.md (opportunities, pipeline)
├── product.md (API usage, features)
└── marketing.md (campaigns, attribution)
```
When a user asks about sales metrics, Claude only reads sales.md.
Similarly, for skills supporting multiple frameworks or variants, organize by variant:
```
cloud-deploy/
├── SKILL.md (workflow + provider selection)
└── references/
├── aws.md (AWS deployment patterns)
├── gcp.md (GCP deployment patterns)
└── azure.md (Azure deployment patterns)
```
When the user chooses AWS, Claude only reads aws.md.
**Pattern 3: Conditional details**
Show basic content, link to advanced content:
```markdown
# DOCX Processing
## Creating documents
Use docx-js for new documents. See [DOCX-JS.md](DOCX-JS.md).
## Editing documents
For simple edits, modify the XML directly.
**For tracked changes**: See [REDLINING.md](REDLINING.md)
**For OOXML details**: See [OOXML.md](OOXML.md)
```
Claude reads REDLINING.md or OOXML.md only when the user needs those features.
**Important guidelines:**
- **Avoid deeply nested references** - Keep references one level deep from SKILL.md. All reference files should link directly from SKILL.md.
- **Structure longer reference files** - For files longer than 100 lines, include a table of contents at the top so Claude can see the full scope when previewing.
## Skill Creation Process
Skill creation involves these steps:
1. Understand the skill with concrete examples
2. Plan reusable skill contents (scripts, references, assets)
3. Initialize the skill (run init_skill.py)
4. Edit the skill (implement resources and write SKILL.md)
5. Package the skill (run package_skill.py)
6. Iterate based on real usage
Follow these steps in order, skipping only if there is a clear reason why they are not applicable.
### Step 1: Understanding the Skill with Concrete Examples
Skip this step only when the skill's usage patterns are already clearly understood. It remains valuable even when working with an existing skill.
To create an effective skill, clearly understand concrete examples of how the skill will be used. This understanding can come from either direct user examples or generated examples that are validated with user feedback.
For example, when building an image-editor skill, relevant questions include:
- "What functionality should the image-editor skill support? Editing, rotating, anything else?"
- "Can you give some examples of how this skill would be used?"
- "I can imagine users asking for things like 'Remove the red-eye from this image' or 'Rotate this image'. Are there other ways you imagine this skill being used?"
- "What would a user say that should trigger this skill?"
To avoid overwhelming users, avoid asking too many questions in a single message. Start with the most important questions and follow up as needed for better effectiveness.
Conclude this step when there is a clear sense of the functionality the skill should support.
### Step 2: Planning the Reusable Skill Contents
To turn concrete examples into an effective skill, analyze each example by:
1. Considering how to execute on the example from scratch
2. Identifying what scripts, references, and assets would be helpful when executing these workflows repeatedly
Example: When building a `pdf-editor` skill to handle queries like "Help me rotate this PDF," the analysis shows:
1. Rotating a PDF requires re-writing the same code each time
2. A `scripts/rotate_pdf.py` script would be helpful to store in the skill
Example: When designing a `frontend-webapp-builder` skill for queries like "Build me a todo app" or "Build me a dashboard to track my steps," the analysis shows:
1. Writing a frontend webapp requires the same boilerplate HTML/React each time
2. An `assets/hello-world/` template containing the boilerplate HTML/React project files would be helpful to store in the skill
Example: When building a `big-query` skill to handle queries like "How many users have logged in today?" the analysis shows:
1. Querying BigQuery requires re-discovering the table schemas and relationships each time
2. A `references/schema.md` file documenting the table schemas would be helpful to store in the skill
To establish the skill's contents, analyze each concrete example to create a list of the reusable resources to include: scripts, references, and assets.
### Step 3: Initializing the Skill
At this point, it is time to actually create the skill.
Skip this step only if the skill being developed already exists, and iteration or packaging is needed. In this case, continue to the next step.
When creating a new skill from scratch, always run the `init_skill.py` script. The script conveniently generates a new template skill directory that automatically includes everything a skill requires, making the skill creation process much more efficient and reliable.
Usage:
```bash
scripts/init_skill.py <skill-name> --path <output-directory>
```
The script:
- Creates the skill directory at the specified path
- Generates a SKILL.md template with proper frontmatter and TODO placeholders
- Creates example resource directories: `scripts/`, `references/`, and `assets/`
- Adds example files in each directory that can be customized or deleted
After initialization, customize or remove the generated SKILL.md and example files as needed.
### Step 4: Edit the Skill
When editing the (newly-generated or existing) skill, remember that the skill is being created for another instance of Claude to use. Include information that would be beneficial and non-obvious to Claude. Consider what procedural knowledge, domain-specific details, or reusable assets would help another Claude instance execute these tasks more effectively.
#### Learn Proven Design Patterns
Consult these helpful guides based on your skill's needs:
- **Multi-step processes**: See references/workflows.md for sequential workflows and conditional logic
- **Specific output formats or quality standards**: See references/output-patterns.md for template and example patterns
These files contain established best practices for effective skill design.
#### Start with Reusable Skill Contents
To begin implementation, start with the reusable resources identified above: `scripts/`, `references/`, and `assets/` files. Note that this step may require user input. For example, when implementing a `brand-guidelines` skill, the user may need to provide brand assets or templates to store in `assets/`, or documentation to store in `references/`.
Added scripts must be tested by actually running them to ensure there are no bugs and that the output matches what is expected. If there are many similar scripts, only a representative sample needs to be tested to ensure confidence that they all work while balancing time to completion.
Any example files and directories not needed for the skill should be deleted. The initialization script creates example files in `scripts/`, `references/`, and `assets/` to demonstrate structure, but most skills won't need all of them.
#### Update SKILL.md
**Writing Guidelines:** Always use imperative/infinitive form.
##### Frontmatter
Write the YAML frontmatter with `name` and `description`:
- `name`: The skill name
- `description`: This is the primary triggering mechanism for your skill, and helps Claude understand when to use the skill.
- Include both what the Skill does and specific triggers/contexts for when to use it.
- Include all "when to use" information here - Not in the body. The body is only loaded after triggering, so "When to Use This Skill" sections in the body are not helpful to Claude.
- Example description for a `docx` skill: "Comprehensive document creation, editing, and analysis with support for tracked changes, comments, formatting preservation, and text extraction. Use when Claude needs to work with professional documents (.docx files) for: (1) Creating new documents, (2) Modifying or editing content, (3) Working with tracked changes, (4) Adding comments, or any other document tasks"
Do not include any other fields in YAML frontmatter.
##### Body
Write instructions for using the skill and its bundled resources.
### Step 5: Packaging a Skill
Once development of the skill is complete, it must be packaged into a distributable .skill file that gets shared with the user. The packaging process automatically validates the skill first to ensure it meets all requirements:
```bash
scripts/package_skill.py <path/to/skill-folder>
```
Optional output directory specification:
```bash
scripts/package_skill.py <path/to/skill-folder> ./dist
```
The packaging script will:
1. **Validate** the skill automatically, checking:
- YAML frontmatter format and required fields
- Skill naming conventions and directory structure
- Description completeness and quality
- File organization and resource references
2. **Package** the skill if validation passes, creating a .skill file named after the skill (e.g., `my-skill.skill`) that includes all files and maintains the proper directory structure for distribution. The .skill file is a zip file with a .skill extension.
If validation fails, the script will report the errors and exit without creating a package. Fix any validation errors and run the packaging command again.
### Step 6: Iterate
After testing the skill, users may request improvements. Often this happens right after using the skill, with fresh context of how the skill performed.
**Iteration workflow:**
1. Use the skill on real tasks
2. Notice struggles or inefficiencies
3. Identify how SKILL.md or bundled resources should be updated
4. Implement changes and test again

# Output Patterns
Use these patterns when skills need to produce consistent, high-quality output.
## Template Pattern
Provide templates for output format. Match the level of strictness to your needs.
**For strict requirements (like API responses or data formats):**
```markdown
## Report structure
ALWAYS use this exact template structure:
# [Analysis Title]
## Executive summary
[One-paragraph overview of key findings]
## Key findings
- Finding 1 with supporting data
- Finding 2 with supporting data
- Finding 3 with supporting data
## Recommendations
1. Specific actionable recommendation
2. Specific actionable recommendation
```
**For flexible guidance (when adaptation is useful):**
```markdown
## Report structure
Here is a sensible default format, but use your best judgment:
# [Analysis Title]
## Executive summary
[Overview]
## Key findings
[Adapt sections based on what you discover]
## Recommendations
[Tailor to the specific context]
Adjust sections as needed for the specific analysis type.
```
## Examples Pattern
For skills where output quality depends on seeing examples, provide input/output pairs:
```markdown
## Commit message format
Generate commit messages following these examples:
**Example 1:**
Input: Added user authentication with JWT tokens
Output:
```
feat(auth): implement JWT-based authentication
Add login endpoint and token validation middleware
```
**Example 2:**
Input: Fixed bug where dates displayed incorrectly in reports
Output:
```
fix(reports): correct date formatting in timezone conversion
Use UTC timestamps consistently across report generation
```
Follow this style: type(scope): brief description, then detailed explanation.
```
Examples help Claude understand the desired style and level of detail more clearly than descriptions alone.

# Workflow Patterns
## Sequential Workflows
For complex tasks, break operations into clear, sequential steps. It is often helpful to give Claude an overview of the process towards the beginning of SKILL.md:
```markdown
Filling a PDF form involves these steps:
1. Analyze the form (run analyze_form.py)
2. Create field mapping (edit fields.json)
3. Validate mapping (run validate_fields.py)
4. Fill the form (run fill_form.py)
5. Verify output (run verify_output.py)
```
## Conditional Workflows
For tasks with branching logic, guide Claude through decision points:
```markdown
1. Determine the modification type:
**Creating new content?** → Follow "Creation workflow" below
**Editing existing content?** → Follow "Editing workflow" below
2. Creation workflow: [steps]
3. Editing workflow: [steps]
```

[TODO: 1-2 sentences explaining what this skill enables]
## Structuring This Skill
[TODO: Choose the structure that best fits this skill's purpose. Common patterns:
**1. Workflow-Based** (best for sequential processes)
- Works well when there are clear step-by-step procedures
- Example: DOCX skill with "Workflow Decision Tree""Reading""Creating""Editing"
- Structure: ## Overview → ## Workflow Decision Tree → ## Step 1 → ## Step 2...
**2. Task-Based** (best for tool collections)
- Works well when the skill offers different operations/capabilities
- Example: PDF skill with "Quick Start""Merge PDFs""Split PDFs""Extract Text"
- Structure: ## Overview → ## Quick Start → ## Task Category 1 → ## Task Category 2...
**3. Reference/Guidelines** (best for standards or specifications)
- Works well for brand guidelines, coding standards, or requirements
- Example: Brand styling with "Brand Guidelines""Colors""Typography""Features"
- Structure: ## Overview → ## Guidelines → ## Specifications → ## Usage...
**4. Capabilities-Based** (best for integrated systems)
- Works well when the skill provides multiple interrelated features
- Example: Product Management with "Core Capabilities" → numbered capability list
- Structure: ## Overview → ## Core Capabilities → ### 1. Feature → ### 2. Feature...
Patterns can be mixed and matched as needed. Most skills combine patterns (e.g., start with task-based, add workflow for complex operations).
Delete this entire "Structuring This Skill" section when done - it's just guidance.]
## [TODO: Replace with the first main section based on chosen structure]
[TODO: Add content here. See examples in existing skills:
- Code samples for technical skills
- Decision trees for complex workflows
- Concrete examples with realistic user requests
- References to scripts/templates/references as needed]
## Resources
This skill includes example resource directories that demonstrate how to organize different types of bundled resources:
### scripts/
Executable code (Python/Bash/etc.) that can be run directly to perform specific operations.
**Examples from other skills:**
- PDF skill: `fill_fillable_fields.py`, `extract_form_field_info.py` - utilities for PDF manipulation
- DOCX skill: `document.py`, `utilities.py` - Python modules for document processing
**Appropriate for:** Python scripts, shell scripts, or any executable code that performs automation, data processing, or specific operations.
**Note:** Scripts may be executed without loading into context, but can still be read by Claude for patching or environment adjustments.
### references/
Documentation and reference material intended to be loaded into context to inform Claude's process and thinking.
**Examples from other skills:**
- Product management: `communication.md`, `context_building.md` - detailed workflow guides
- BigQuery: API reference documentation and query examples
- Finance: Schema documentation, company policies
**Appropriate for:** In-depth documentation, API references, database schemas, comprehensive guides, or any detailed information that Claude should reference while working.
### assets/
Files not intended to be loaded into context, but rather used within the output Claude produces.
**Examples from other skills:**
- Brand styling: PowerPoint template files (.pptx), logo files
- Frontend builder: HTML/React boilerplate project directories
- Typography: Font files (.ttf, .woff2)
**Appropriate for:** Templates, boilerplate code, document templates, images, icons, fonts, or any files meant to be copied or used in the final output.

name: parallel-execution
description: Patterns for parallel subagent execution using Task tool with run_in_background. Use when coordinating multiple independent tasks, spawning dynamic subagents, or implementing features that can be parallelized.
---
# Parallel Execution Patterns
## Core Concept
Parallel execution spawns multiple subagents simultaneously using the Task tool with `run_in_background: true`. This enables N tasks to run concurrently, dramatically reducing total execution time.
**Critical Rule**: ALL Task calls MUST be in a SINGLE assistant message for true parallelism. If Task calls are in separate messages, they run sequentially.
## Execution Protocol
### Step 1: Identify Parallelizable Tasks
Before spawning, verify tasks are independent:
- No task depends on another's output
- Tasks target different files or concerns
- Can run simultaneously without conflicts
### Step 2: Prepare Dynamic Subagent Prompts
Each subagent receives a custom prompt defining its role:
```
You are a [ROLE] specialist for this specific task.
Task: [CLEAR DESCRIPTION]
Context:
[RELEVANT CONTEXT ABOUT THE CODEBASE/PROJECT]
Files to work with:
[SPECIFIC FILES OR PATTERNS]
Output format:
[EXPECTED OUTPUT STRUCTURE]
Focus areas:
- [PRIORITY 1]
- [PRIORITY 2]
```
### Step 3: Launch All Tasks in ONE Message
**CRITICAL**: Make ALL Task calls in the SAME assistant message:
```
I'm launching N parallel subagents:
[Task 1]
description: "Subagent A - [brief purpose]"
prompt: "[detailed instructions for subagent A]"
run_in_background: true
[Task 2]
description: "Subagent B - [brief purpose]"
prompt: "[detailed instructions for subagent B]"
run_in_background: true
[Task 3]
description: "Subagent C - [brief purpose]"
prompt: "[detailed instructions for subagent C]"
run_in_background: true
```
### Step 4: Retrieve Results with TaskOutput
After launching, retrieve each result:
```
[Wait for completion, then retrieve]
TaskOutput: task_1_id
TaskOutput: task_2_id
TaskOutput: task_3_id
```
### Step 5: Synthesize Results
Combine all subagent outputs into unified result:
- Merge related findings
- Resolve conflicts between recommendations
- Prioritize by severity/importance
- Create actionable summary
## Dynamic Subagent Patterns
### Pattern 1: Task-Based Parallelization
When you have N tasks to implement, spawn N subagents:
```
Plan:
1. Implement auth module
2. Create API endpoints
3. Add database schema
4. Write unit tests
5. Update documentation
Spawn 5 subagents (one per task):
- Subagent 1: Implements auth module
- Subagent 2: Creates API endpoints
- Subagent 3: Adds database schema
- Subagent 4: Writes unit tests
- Subagent 5: Updates documentation
```
### Pattern 2: Directory-Based Parallelization
Analyze multiple directories simultaneously:
```
Directories: src/auth, src/api, src/db
Spawn 3 subagents:
- Subagent 1: Analyzes src/auth
- Subagent 2: Analyzes src/api
- Subagent 3: Analyzes src/db
```
### Pattern 3: Perspective-Based Parallelization
Review from multiple angles simultaneously:
```
Perspectives: Security, Performance, Testing, Architecture
Spawn 4 subagents:
- Subagent 1: Security review
- Subagent 2: Performance analysis
- Subagent 3: Test coverage review
- Subagent 4: Architecture assessment
```
## TodoWrite Integration
When using parallel execution, TodoWrite behavior differs:
**Sequential execution**: Only ONE task `in_progress` at a time
**Parallel execution**: MULTIPLE tasks can be `in_progress` simultaneously
```
# Before launching parallel tasks
todos = [
{ content: "Task A", status: "in_progress" },
{ content: "Task B", status: "in_progress" },
{ content: "Task C", status: "in_progress" },
{ content: "Synthesize results", status: "pending" }
]
# After each TaskOutput retrieval, mark as completed
todos = [
{ content: "Task A", status: "completed" },
{ content: "Task B", status: "completed" },
{ content: "Task C", status: "completed" },
{ content: "Synthesize results", status: "in_progress" }
]
```
## When to Use Parallel Execution
**Good candidates:**
- Multiple independent analyses (code review, security, tests)
- Multi-file processing where files are independent
- Exploratory tasks with different perspectives
- Verification tasks with different checks
- Feature implementation with independent components
**Avoid parallelization when:**
- Tasks have dependencies (Task B needs Task A's output)
- Sequential workflows are required (commit -> push -> PR)
- Tasks modify the same files (risk of conflicts)
- Order matters for correctness
## Performance Benefits
| Approach | 5 Tasks @ 30s each | Total Time |
|----------|-------------------|------------|
| Sequential | 30s + 30s + 30s + 30s + 30s | ~150s |
| Parallel | All 5 run simultaneously | ~30s |
Parallel execution is approximately Nx faster where N is the number of independent tasks.
## Example: Feature Implementation
**User request**: "Implement user authentication with login, registration, and password reset"
**Orchestrator creates plan**:
1. Implement login endpoint
2. Implement registration endpoint
3. Implement password reset endpoint
4. Add authentication middleware
5. Write integration tests
**Parallel execution**:
```
Launching 5 subagents in parallel:
[Task 1] Login endpoint implementation
[Task 2] Registration endpoint implementation
[Task 3] Password reset endpoint implementation
[Task 4] Auth middleware implementation
[Task 5] Integration test writing
All tasks run simultaneously...
[Collect results via TaskOutput]
[Synthesize into cohesive implementation]
```
## Troubleshooting
**Tasks running sequentially?**
- Verify ALL Task calls are in SINGLE message
- Check `run_in_background: true` is set for each
**Results not available?**
- Use TaskOutput with correct task IDs
- Wait for tasks to complete before retrieving
**Conflicts in output?**
- Ensure tasks don't modify same files
- Add conflict resolution in synthesis step

# Payload CMS Development
Payload is a Next.js native CMS with TypeScript-first architecture. This skill transfers expert knowledge for building collections, hooks, access control, and queries the right way.
## Mental Model
Think of Payload as **three interconnected layers**:
1. **Config Layer** → Collections, globals, fields define your schema
2. **Hook Layer** → Lifecycle events transform and validate data
3. **Access Layer** → Functions control who can do what
Every operation flows through: `Config → Access Check → Hook Chain → Database → Response Hooks`
## Quick Reference
| Task | Solution | Details |
|------|----------|---------|
| Auto-generate slugs | `slugField()` or beforeChange hook | [references/fields.md#slug-field] |
| Restrict by user | Access control with query constraint | [references/access-control.md] |
| Local API with auth | `user` + `overrideAccess: false` | [references/queries.md#local-api] |
| Draft/publish | `versions: { drafts: true }` | [references/collections.md#drafts] |
| Computed fields | `virtual: true` with afterRead hook | [references/fields.md#virtual] |
| Conditional fields | `admin.condition` | [references/fields.md#conditional] |
| Filter relationships | `filterOptions` on field | [references/fields.md#relationship] |
| Prevent hook loops | `req.context` flag | [references/hooks.md#context] |
| Transactions | Pass `req` to all operations | [references/hooks.md#transactions] |
| Background jobs | Jobs queue with tasks | [references/advanced.md#jobs] |
## Quick Start
```bash
npx create-payload-app@latest my-app
cd my-app
pnpm dev
```
### Minimal Config
```ts
import { buildConfig } from 'payload'
import { mongooseAdapter } from '@payloadcms/db-mongodb'
import { lexicalEditor } from '@payloadcms/richtext-lexical'
export default buildConfig({
admin: { user: 'users' },
collections: [Users, Media, Posts],
editor: lexicalEditor(),
secret: process.env.PAYLOAD_SECRET,
typescript: { outputFile: 'payload-types.ts' },
db: mongooseAdapter({ url: process.env.DATABASE_URL }),
})
```
## Core Patterns
### Collection Definition
```ts
import type { CollectionConfig } from 'payload'
export const Posts: CollectionConfig = {
slug: 'posts',
admin: {
useAsTitle: 'title',
defaultColumns: ['title', 'author', 'status', 'createdAt'],
},
fields: [
{ name: 'title', type: 'text', required: true },
{ name: 'slug', type: 'text', unique: true, index: true },
{ name: 'content', type: 'richText' },
{ name: 'author', type: 'relationship', relationTo: 'users' },
{ name: 'status', type: 'select', options: ['draft', 'published'], defaultValue: 'draft' },
],
timestamps: true,
}
```
### Hook Pattern (Auto-slug)
```ts
export const Posts: CollectionConfig = {
slug: 'posts',
hooks: {
beforeChange: [
async ({ data, operation }) => {
if (operation === 'create' && data.title) {
data.slug = data.title.toLowerCase().replace(/\s+/g, '-')
}
return data
},
],
},
fields: [{ name: 'title', type: 'text', required: true }],
}
```
### Access Control Pattern
```ts
import type { Access } from 'payload'
// Type-safe: admin-only access
export const adminOnly: Access = ({ req }) => {
return req.user?.roles?.includes('admin') ?? false
}
// Row-level: users see only their own posts
export const ownPostsOnly: Access = ({ req }) => {
if (!req.user) return false
if (req.user.roles?.includes('admin')) return true
return { author: { equals: req.user.id } }
}
```
### Query Pattern
```ts
// Local API with access control
const posts = await payload.find({
collection: 'posts',
where: {
status: { equals: 'published' },
'author.name': { contains: 'john' },
},
depth: 2,
limit: 10,
sort: '-createdAt',
user: req.user,
overrideAccess: false, // CRITICAL: enforce permissions
})
```
## Critical Security Rules
### 1. Local API Access Control
**Default behavior bypasses ALL access control.** This is the #1 security mistake.
```ts
// ❌ SECURITY BUG: Access control bypassed even with user
await payload.find({ collection: 'posts', user: someUser })
// ✅ SECURE: Explicitly enforce permissions
await payload.find({
collection: 'posts',
user: someUser,
overrideAccess: false, // REQUIRED
})
```
**Rule:** Use `overrideAccess: false` for any operation acting on behalf of a user.
### 2. Transaction Integrity
**Operations without `req` run in separate transactions.**
```ts
// ❌ DATA CORRUPTION: Separate transaction
hooks: {
afterChange: [async ({ doc, req }) => {
await req.payload.create({
collection: 'audit-log',
data: { docId: doc.id },
// Missing req - breaks atomicity!
})
}]
}
// ✅ ATOMIC: Same transaction
hooks: {
afterChange: [async ({ doc, req }) => {
await req.payload.create({
collection: 'audit-log',
data: { docId: doc.id },
req, // Maintains transaction
})
}]
}
```
**Rule:** Always pass `req` to nested operations in hooks.
### 3. Infinite Hook Loops
**Hooks triggering themselves create infinite loops.**
```ts
// ❌ INFINITE LOOP
hooks: {
afterChange: [async ({ doc, req }) => {
await req.payload.update({
collection: 'posts',
id: doc.id,
data: { views: doc.views + 1 },
req,
}) // Triggers afterChange again!
}]
}
// ✅ SAFE: Context flag breaks the loop
hooks: {
afterChange: [async ({ doc, req, context }) => {
if (context.skipViewUpdate) return
await req.payload.update({
collection: 'posts',
id: doc.id,
data: { views: doc.views + 1 },
req,
context: { skipViewUpdate: true },
})
}]
}
```
## Project Structure
```
src/
├── app/
│ ├── (frontend)/page.tsx
│ └── (payload)/admin/[[...segments]]/page.tsx
├── collections/
│ ├── Posts.ts
│ ├── Media.ts
│ └── Users.ts
├── globals/Header.ts
├── hooks/slugify.ts
└── payload.config.ts
```
## Type Generation
Generate types after schema changes:
```ts
// payload.config.ts
export default buildConfig({
typescript: { outputFile: 'payload-types.ts' },
})
// Usage
import type { Post, User } from '@/payload-types'
```
## Getting Payload Instance
```ts
// In API routes
import { getPayload } from 'payload'
import config from '@payload-config'
export async function GET() {
const payload = await getPayload({ config })
const posts = await payload.find({ collection: 'posts' })
return Response.json(posts)
}
// In Server Components
export default async function Page() {
const payload = await getPayload({ config })
const { docs } = await payload.find({ collection: 'posts' })
return <div>{docs.map(p => <h1 key={p.id}>{p.title}</h1>)}</div>
}
```
## Common Field Types
```ts
// Text
{ name: 'title', type: 'text', required: true }
// Relationship
{ name: 'author', type: 'relationship', relationTo: 'users' }
// Rich text
{ name: 'content', type: 'richText' }
// Select
{ name: 'status', type: 'select', options: ['draft', 'published'] }
// Upload
{ name: 'image', type: 'upload', relationTo: 'media' }
// Array
{
name: 'tags',
type: 'array',
fields: [{ name: 'tag', type: 'text' }],
}
// Blocks (polymorphic content)
{
name: 'layout',
type: 'blocks',
blocks: [HeroBlock, ContentBlock, CTABlock],
}
```
## Decision Framework
**When choosing between approaches:**
| Scenario | Approach |
|----------|----------|
| Data transformation before save | `beforeChange` hook |
| Data transformation after read | `afterRead` hook |
| Enforce business rules | Access control function |
| Complex validation | `validate` function on field |
| Computed display value | Virtual field with `afterRead` |
| Related docs list | `join` field type |
| Side effects (email, webhook) | `afterChange` hook with context guard |
| Database-level constraint | Field with `unique: true` or `index: true` |
## Quality Checks
Good Payload code:
- [ ] All Local API calls with user context use `overrideAccess: false`
- [ ] All hook operations pass `req` for transaction integrity
- [ ] Recursive hooks use `context` flags
- [ ] Types generated and imported from `payload-types.ts`
- [ ] Access control functions are typed with `Access` type
- [ ] Collections have meaningful `admin.useAsTitle` set

# Access Control Reference
## Overview
Access control functions determine WHO can do WHAT with documents:
```ts
type Access = (args: AccessArgs) => boolean | Where | Promise<boolean | Where>
```
Returns:
- `true` - Full access
- `false` - No access
- `Where` query - Filtered access (row-level security)
## Collection-Level Access
```ts
export const Posts: CollectionConfig = {
slug: 'posts',
access: {
create: isLoggedIn,
read: isPublishedOrAdmin,
update: isAdminOrAuthor,
delete: isAdmin,
},
fields: [...],
}
```
## Common Patterns
### Public Read, Admin Write
```ts
const isAdmin: Access = ({ req }) => {
return req.user?.roles?.includes('admin') ?? false
}
const isLoggedIn: Access = ({ req }) => {
return !!req.user
}
access: {
create: isLoggedIn,
read: () => true, // Public
update: isAdmin,
delete: isAdmin,
}
```
### Row-Level Security (User's Own Documents)
```ts
const ownDocsOnly: Access = ({ req }) => {
if (!req.user) return false
// Admins see everything
if (req.user.roles?.includes('admin')) return true
// Others see only their own
return {
author: { equals: req.user.id },
}
}
access: {
read: ownDocsOnly,
update: ownDocsOnly,
delete: ownDocsOnly,
}
```
### Complex Queries
```ts
const publishedOrOwn: Access = ({ req }) => {
// Not logged in: published only
if (!req.user) {
return { status: { equals: 'published' } }
}
// Admin: see all
if (req.user.roles?.includes('admin')) return true
// Others: published OR own drafts
return {
or: [
{ status: { equals: 'published' } },
{ author: { equals: req.user.id } },
],
}
}
```
## Field-Level Access
Control access to specific fields:
```ts
{
name: 'internalNotes',
type: 'textarea',
access: {
read: ({ req }) => req.user?.roles?.includes('admin'),
update: ({ req }) => req.user?.roles?.includes('admin'),
},
}
```
### Hide Field Completely
```ts
{
name: 'secretKey',
type: 'text',
access: {
read: () => false, // Never returned in API
update: ({ req }) => req.user?.roles?.includes('admin'),
},
}
```
## Access Control Arguments
```ts
type AccessArgs = {
req: PayloadRequest
id?: string | number // Document ID (for update/delete)
data?: Record<string, unknown> // Incoming data (for create/update)
}
```
## RBAC (Role-Based Access Control)
```ts
// Define roles
type Role = 'admin' | 'editor' | 'author' | 'subscriber'
// Helper functions
const hasRole = (req: PayloadRequest, role: Role): boolean => {
return req.user?.roles?.includes(role) ?? false
}
const hasAnyRole = (req: PayloadRequest, roles: Role[]): boolean => {
return roles.some(role => hasRole(req, role))
}
// Use in access control
const canEdit: Access = ({ req }) => {
return hasAnyRole(req, ['admin', 'editor'])
}
const canPublish: Access = ({ req }) => {
return hasAnyRole(req, ['admin', 'editor'])
}
const canDelete: Access = ({ req }) => {
return hasRole(req, 'admin')
}
```
## Multi-Tenant Access
```ts
// Users belong to organizations
const sameOrgOnly: Access = ({ req }) => {
if (!req.user) return false
// Super admin sees all
if (req.user.roles?.includes('super-admin')) return true
// Others see only their org's data
return {
organization: { equals: req.user.organization },
}
}
// Apply to collection
access: {
create: ({ req }) => !!req.user,
read: sameOrgOnly,
update: sameOrgOnly,
delete: sameOrgOnly,
}
```
## Global Access
For singleton documents:
```ts
export const Settings: GlobalConfig = {
slug: 'settings',
access: {
read: () => true,
update: ({ req }) => req.user?.roles?.includes('admin'),
},
fields: [...],
}
```
## Important: Local API Access Control
**Local API bypasses access control by default!**
```ts
// ❌ SECURITY BUG: Access control bypassed
await payload.find({
collection: 'posts',
user: someUser,
})
// ✅ SECURE: Explicitly enforce access control
await payload.find({
collection: 'posts',
user: someUser,
overrideAccess: false, // REQUIRED
})
```
## Access Control with req.context
Share state between access checks and hooks:
```ts
const conditionalAccess: Access = ({ req }) => {
// Check context set by middleware or previous operation
if (req.context?.bypassAuth) return true
return req.user?.roles?.includes('admin')
}
```
## Best Practices
1. **Default to restrictive** - Start with `false`, add permissions
2. **Use query constraints for row-level** - More efficient than filtering after
3. **Keep logic in reusable functions** - DRY across collections
4. **Test with different user types** - Admin, regular user, anonymous
5. **Remember Local API default** - Always use `overrideAccess: false` for user-facing operations
6. **Document your access rules** - Complex logic needs comments

# Advanced Features Reference
## Jobs Queue
Background task processing:
### Define Tasks
```ts
// payload.config.ts
export default buildConfig({
jobs: {
tasks: [
{
slug: 'sendEmail',
handler: async ({ payload, job }) => {
const { to, subject, body } = job.input
await sendEmail({ to, subject, body })
},
inputSchema: {
to: { type: 'text', required: true },
subject: { type: 'text', required: true },
body: { type: 'text', required: true },
},
},
{
slug: 'generateThumbnails',
handler: async ({ payload, job }) => {
const { mediaId } = job.input
// Process images...
},
},
],
},
})
```
### Queue Jobs
```ts
// In a hook or endpoint
await payload.jobs.queue({
task: 'sendEmail',
input: {
to: 'user@example.com',
subject: 'Welcome!',
body: 'Thanks for signing up.',
},
})
```
### Run Jobs
```bash
# In production, run job worker
payload jobs:run
```
## Custom Endpoints
### Collection Endpoints
```ts
export const Posts: CollectionConfig = {
slug: 'posts',
endpoints: [

handler: async (req) => {
const { id } = req.routeParams
const doc = await req.payload.update({
collection: 'posts',
id,
data: {
status: 'published',
publishedAt: new Date(),
},
req,
overrideAccess: false, // Respect permissions
})
return Response.json({ success: true, doc })
},
},
{
path: '/stats',
method: 'get',
handler: async (req) => {
const total = await req.payload.count({ collection: 'posts' })
const published = await req.payload.count({

where: { status: { equals: 'published' } },
})
return Response.json({
total: total.totalDocs,
published: published.totalDocs,
})
},

# Field Types Reference
## Core Field Types
### Text Fields
```ts
// Basic text
{ name: 'title', type: 'text', required: true }
// With validation
{
name: 'email',
type: 'text',
validate: (value) => {
if (!value?.includes('@')) return 'Invalid email'
return true
},
}
// With admin config
{
name: 'description',
type: 'textarea',
admin: {
placeholder: 'Enter description...',
description: 'Brief summary',
},
}
```
### Slug Field Helper
Auto-generate URL-safe slugs:
```ts
import { slugField } from '@payloadcms/plugin-seo'
// Or manual implementation
{
name: 'slug',
type: 'text',
unique: true,
index: true,
hooks: {
beforeValidate: [
({ data, operation, originalDoc }) => {
if (operation === 'create' || !originalDoc?.slug) {
return data?.title?.toLowerCase().replace(/\s+/g, '-')
}
return originalDoc.slug
},
],
},
}
```
### Number Fields
```ts
{ name: 'price', type: 'number', min: 0, required: true }
{ name: 'quantity', type: 'number', defaultValue: 1 }
```
### Select Fields
```ts
// Simple select
{
name: 'status',
type: 'select',
options: ['draft', 'published', 'archived'],
defaultValue: 'draft',
}
// With labels
{
name: 'priority',
type: 'select',
options: [
{ label: 'Low', value: 'low' },
{ label: 'Medium', value: 'medium' },
{ label: 'High', value: 'high' },
],
}
// Multi-select
{
name: 'categories',
type: 'select',
hasMany: true,
options: ['tech', 'design', 'marketing'],
}
```
### Checkbox
```ts
{ name: 'featured', type: 'checkbox', defaultValue: false }
```
### Date Fields
```ts
{ name: 'publishedAt', type: 'date' }
// With time
{
name: 'eventDate',
type: 'date',
admin: { date: { pickerAppearance: 'dayAndTime' } },
}
```
## Relationship Fields
### Basic Relationship
```ts
// Single relationship
{
name: 'author',
type: 'relationship',
relationTo: 'users',
required: true,
}
// Multiple relationships (hasMany)
{
name: 'tags',
type: 'relationship',
relationTo: 'tags',
hasMany: true,
}
// Polymorphic (multiple collections)
{
name: 'parent',
type: 'relationship',
relationTo: ['pages', 'posts'],
}
```
### With Filter Options
Dynamically filter available options:
```ts
{
name: 'relatedPosts',
type: 'relationship',
relationTo: 'posts',
hasMany: true,
filterOptions: ({ data }) => ({
// Only show published posts, exclude self
status: { equals: 'published' },
id: { not_equals: data?.id },
}),
}
```
### Join Fields
Reverse relationship lookup (virtual field):
```ts
// In Posts collection
{
name: 'comments',
type: 'join',
collection: 'comments',
on: 'post', // field name in comments that references posts
}
```
## Virtual Fields
Computed fields that don't store data:
```ts
{
name: 'fullName',
type: 'text',
virtual: true,
hooks: {
afterRead: [
({ data }) => `${data?.firstName} ${data?.lastName}`,
],
},
}
```
## Conditional Fields
Show/hide fields based on other values:
```ts
{
name: 'isExternal',
type: 'checkbox',
},
{
name: 'externalUrl',
type: 'text',
admin: {
condition: (data) => data?.isExternal === true,
},
}
```
## Validation
### Custom Validation
```ts
{
name: 'slug',
type: 'text',
validate: (value, { data, operation }) => {
if (!value) return 'Slug is required'
if (!/^[a-z0-9-]+$/.test(value)) {
return 'Slug must be lowercase letters, numbers, and hyphens only'
}
return true
},
}
```
### Async Validation
```ts
{
name: 'username',
type: 'text',
validate: async (value, { payload }) => {
if (!value) return true
const existing = await payload.find({
collection: 'users',
where: { username: { equals: value } },
})
if (existing.docs.length > 0) return 'Username already taken'
return true
},
}
```
## Group Fields
Organize related fields:
```ts
{
name: 'meta',
type: 'group',
fields: [
{ name: 'title', type: 'text' },
{ name: 'description', type: 'textarea' },
],
}
```
## Array Fields
Repeatable sets of fields:
```ts
{
name: 'socialLinks',
type: 'array',
fields: [
{ name: 'platform', type: 'select', options: ['twitter', 'linkedin', 'github'] },
{ name: 'url', type: 'text' },
],
}
```
## Blocks (Polymorphic Content)
Different content types in same array:
```ts
{
name: 'layout',
type: 'blocks',
blocks: [
{
slug: 'hero',
fields: [
{ name: 'heading', type: 'text' },
{ name: 'image', type: 'upload', relationTo: 'media' },
],
},
{
slug: 'content',
fields: [
{ name: 'richText', type: 'richText' },
],
},
],
}
```
## Point (Geolocation)
```ts
{
name: 'location',
type: 'point',
label: 'Location',
}
// Query nearby
await payload.find({
collection: 'stores',
where: {
location: {
near: [-73.935242, 40.730610, 5000], // lng, lat, maxDistance (meters)
},
},
})
```
## Upload Fields
```ts
{
name: 'featuredImage',
type: 'upload',
relationTo: 'media',
required: true,
}
```
## Rich Text
```ts
{
name: 'content',
type: 'richText',
// Lexical editor features configured in payload.config.ts
}
```
## UI Fields (Presentational)
Fields that don't save data:
```ts
// Row layout
{
type: 'row',
fields: [
{ name: 'firstName', type: 'text', admin: { width: '50%' } },
{ name: 'lastName', type: 'text', admin: { width: '50%' } },
],
}
// Tabs

type: 'tabs',
tabs: [
{ label: 'Content', fields: [...] },
{ label: 'Meta', fields: [...] },
],
}
// Collapsible
{
type: 'collapsible',
label: 'Advanced Options',
fields: [...],
}

# Hooks Reference
## Hook Lifecycle
```
Operation: CREATE
beforeOperation → beforeValidate → beforeChange → [DB Write] → afterChange → afterOperation
Operation: UPDATE
beforeOperation → beforeValidate → beforeChange → [DB Write] → afterChange → afterOperation
Operation: READ
beforeOperation → beforeRead → [DB Read] → afterRead → afterOperation
Operation: DELETE
beforeOperation → beforeDelete → [DB Delete] → afterDelete → afterOperation
```
## Collection Hooks
### beforeValidate
Transform data before validation runs:
```ts
hooks: {
beforeValidate: [
async ({ data, operation, req }) => {
if (operation === 'create') {
data.createdBy = req.user?.id
}
return data // Always return data
},
],
}
```
### beforeChange
Transform data before database write (after validation):
```ts
hooks: {
beforeChange: [
async ({ data, operation, originalDoc, req }) => {
// Auto-generate slug on create
if (operation === 'create' && data.title) {
data.slug = data.title.toLowerCase().replace(/\s+/g, '-')
}
// Track last modified by
data.lastModifiedBy = req.user?.id
return data
},
],
}
```
### afterChange
Side effects after database write:
```ts
hooks: {
afterChange: [
async ({ doc, operation, req, context }) => {
// Prevent infinite loops
if (context.skipAuditLog) return doc
// Create audit log entry
await req.payload.create({
collection: 'audit-logs',
data: {
action: operation,
collection: 'posts',
documentId: doc.id,
userId: req.user?.id,
timestamp: new Date(),
},
req, // CRITICAL: maintains transaction
context: { skipAuditLog: true },
})
return doc
},
],
}
```
### beforeRead
Modify query before database read:
```ts
hooks: {
beforeRead: [
async ({ doc, req }) => {
// doc is the raw database document
// Can modify before afterRead transforms
return doc
},
],
}
```
### afterRead
Transform data before sending to client:
```ts
hooks: {
afterRead: [
async ({ doc, req }) => {
// Add computed field
doc.fullName = `${doc.firstName} ${doc.lastName}`
// Hide sensitive data for non-admins
if (!req.user?.roles?.includes('admin')) {
delete doc.internalNotes
}
return doc
},
],
}
```
### beforeDelete
Pre-delete validation or cleanup:
```ts
hooks: {
beforeDelete: [
async ({ id, req }) => {
// Cascading delete: remove related comments
await req.payload.delete({
collection: 'comments',
where: { post: { equals: id } },
req,
})
},
],
}
```
### afterDelete
Post-delete cleanup:
```ts
hooks: {
afterDelete: [
async ({ doc, req }) => {
// Clean up uploaded files
if (doc.image) {
await deleteFile(doc.image.filename)
}
},
],
}
```
## Field Hooks
Hooks on individual fields:
```ts
{
name: 'slug',
type: 'text',
hooks: {
beforeValidate: [
({ value, data }) => {
if (!value && data?.title) {
return data.title.toLowerCase().replace(/\s+/g, '-')
}
return value
},
],
afterRead: [
({ value }) => value?.toLowerCase(),
],
},
}
```
## Context Pattern
**Prevent infinite loops and share state between hooks:**
```ts
hooks: {
afterChange: [
async ({ doc, req, context }) => {
// Check context flag to prevent loops
if (context.skipNotification) return doc
// Trigger related update with context flag
await req.payload.update({
collection: 'related',
id: doc.relatedId,
data: { updated: true },
req,
context: {
...context,
skipNotification: true, // Prevent loop
},
})
return doc
},
],
}
```
## Transactions
**CRITICAL: Always pass `req` for transaction integrity:**
```ts
hooks: {
afterChange: [
async ({ doc, req }) => {
// ✅ Same transaction - atomic
await req.payload.create({
collection: 'audit-logs',
data: { documentId: doc.id },
req, // REQUIRED
})
// ❌ Separate transaction - can leave inconsistent state
await req.payload.create({
collection: 'audit-logs',
data: { documentId: doc.id },
// Missing req!
})
return doc
},
],
}
```
## Next.js Revalidation with Context Control
```ts
import { revalidatePath, revalidateTag } from 'next/cache'
hooks: {
afterChange: [
async ({ doc, context }) => {
// Skip revalidation for internal updates
if (context.skipRevalidation) return doc
revalidatePath(`/posts/${doc.slug}`)
revalidateTag('posts')
return doc
},
],
}
```
## Auth Hooks (Auth Collections Only)
```ts
export const Users: CollectionConfig = {
slug: 'users',
auth: true,
hooks: {
afterLogin: [
async ({ doc, req }) => {
// Log login
await req.payload.create({
collection: 'login-logs',
data: { userId: doc.id, timestamp: new Date() },
req,
})
return doc
},
],
afterLogout: [
async ({ req }) => {
// Clear session data
},
],
afterMe: [
async ({ doc, req }) => {
// Add extra user info
return doc
},
],
afterRefresh: [
async ({ doc, req }) => {
// Custom token refresh logic
return doc
},
],
afterForgotPassword: [
async ({ args }) => {
// Custom forgot password notification
},

## Hook Arguments Reference
All hooks receive these base arguments:
| Argument | Description |
|----------|-------------|
| `req` | Request object with `payload`, `user`, `locale` |
| `context` | Shared context object between hooks |
| `collection` | Collection config |
Operation-specific arguments:
| Hook | Additional Arguments |
|------|---------------------|
| `beforeValidate` | `data`, `operation`, `originalDoc` |
| `beforeChange` | `data`, `operation`, `originalDoc` |
| `afterChange` | `doc`, `operation`, `previousDoc` |
| `beforeRead` | `doc` |
| `afterRead` | `doc` |
| `beforeDelete` | `id` |
| `afterDelete` | `doc`, `id` |
## Best Practices
1. **Always return the data/doc** - Even if unchanged
2. **Use context for loop prevention** - Check before triggering recursive operations
3. **Pass req for transactions** - Maintains atomicity
4. **Keep hooks focused** - One responsibility per hook
5. **Use field hooks for field-specific logic** - Better encapsulation
6. **Avoid heavy operations in beforeRead** - Runs on every query
7. **Use afterChange for side effects** - Email, webhooks, etc.

# Queries Reference
## Local API
### Find Multiple
```ts
const result = await payload.find({
collection: 'posts',
where: {
status: { equals: 'published' },
},
limit: 10,
page: 1,
sort: '-createdAt',
depth: 2,
})
// Result structure
{
docs: Post[],
totalDocs: number,
limit: number,
totalPages: number,
page: number,
pagingCounter: number,
hasPrevPage: boolean,
hasNextPage: boolean,
prevPage: number | null,
nextPage: number | null,
}
```
### Find By ID
```ts
const post = await payload.findByID({
collection: 'posts',
id: '123',
depth: 2,
})
```
### Create
```ts
const newPost = await payload.create({
collection: 'posts',
data: {
title: 'New Post',
content: '...',
author: userId,
},
user: req.user, // For access control
})
```
### Update
```ts
const updated = await payload.update({
collection: 'posts',
id: '123',
data: {
title: 'Updated Title',
},
})
```
### Delete
```ts
const deleted = await payload.delete({
collection: 'posts',
id: '123',
})
```
## Query Operators
### Comparison
```ts
where: {
price: { equals: 100 },
price: { not_equals: 100 },
price: { greater_than: 100 },
price: { greater_than_equal: 100 },
price: { less_than: 100 },
price: { less_than_equal: 100 },
}
```
### String Operations
```ts
where: {
title: { like: 'Hello' }, // Case-insensitive contains
title: { contains: 'world' }, // Case-sensitive contains
email: { exists: true }, // Field has value
}
```
### Array Operations
```ts
where: {
tags: { in: ['tech', 'design'] }, // Value in array
tags: { not_in: ['spam'] }, // Value not in array
tags: { all: ['featured', 'popular'] }, // Has all values
}
```
### AND/OR Logic
```ts
where: {
and: [
{ status: { equals: 'published' } },
{ author: { equals: userId } },
],
}
where: {
or: [
{ status: { equals: 'published' } },
{ author: { equals: userId } },
],
}
// Nested
where: {
and: [
{ status: { equals: 'published' } },
{
or: [
{ featured: { equals: true } },
{ 'author.roles': { in: ['admin'] } },
],
},
],
}
```
### Nested Properties
Query through relationships:
```ts
where: {
'author.name': { contains: 'John' },
'category.slug': { equals: 'tech' },
}
```
### Geospatial Queries
```ts
where: {
location: {
near: [-73.935242, 40.730610, 10000], // [lng, lat, maxDistanceMeters]
},
}
where: {
location: {
within: {
type: 'Polygon',
coordinates: [[[-74, 40], [-73, 40], [-73, 41], [-74, 41], [-74, 40]]],
},
},
}
```
## Field Selection
Only fetch specific fields:
```ts
const posts = await payload.find({
collection: 'posts',
select: {
title: true,
slug: true,
author: true, // Will be populated based on depth
},
})
```
## Depth (Relationship Population)
```ts
// depth: 0 - IDs only
{ author: '123' }
// depth: 1 - First level populated
{ author: { id: '123', name: 'John' } }
// depth: 2 (default) - Nested relationships populated
{ author: { id: '123', name: 'John', avatar: { url: '...' } } }
```
## Pagination
```ts
// Page-based
await payload.find({
collection: 'posts',
page: 2,
limit: 20,
})
// Cursor-based (more efficient for large datasets)
await payload.find({
collection: 'posts',
where: {
createdAt: { greater_than: lastCursor },
},
limit: 20,
sort: 'createdAt',
})
```
## Sorting
```ts
// Single field
sort: 'createdAt' // Ascending
sort: '-createdAt' // Descending
// Multiple fields
sort: ['-featured', '-createdAt']
```
## Access Control in Local API
**CRITICAL: Local API bypasses access control by default!**
```ts
// ❌ INSECURE: Access control bypassed
await payload.find({
collection: 'posts',
user: someUser, // User is ignored!
})
// ✅ SECURE: Access control enforced
await payload.find({
collection: 'posts',
user: someUser,
overrideAccess: false, // REQUIRED
})
```
## REST API
### Endpoints
```
GET /api/{collection} # Find
GET /api/{collection}/{id} # Find by ID
POST /api/{collection} # Create
PATCH /api/{collection}/{id} # Update
DELETE /api/{collection}/{id} # Delete
```
### Query String
```
GET /api/posts?where[status][equals]=published&limit=10&sort=-createdAt&depth=2
```
### Nested Queries
```
GET /api/posts?where[author.name][contains]=John
```
### Complex Queries
```
GET /api/posts?where[or][0][status][equals]=published&where[or][1][author][equals]=123
```
## GraphQL API
### Query
```graphql
query {
Posts(
where: { status: { equals: published } }
limit: 10
sort: "-createdAt"
) {
docs {
id
title
author {
name
}
}
totalDocs
}
}
```
### Mutation
```graphql
mutation {
createPost(data: { title: "New Post", status: draft }) {
id
title
}
}
```
## Draft Queries
```ts
// Published only (default)
await payload.find({ collection: 'posts' })
// Include drafts
await payload.find({
collection: 'posts',
draft: true,
})
```
## Count Only
```ts
const count = await payload.count({
collection: 'posts',
where: { status: { equals: 'published' } },
})
// Returns: { totalDocs: number }
```
## Distinct Values
```ts
const categories = await payload.find({
collection: 'posts',
select: { category: true },
// Then dedupe in code
})
```
## Performance Tips
1. **Use indexes** - Add `index: true` to frequently queried fields
2. **Limit depth** - Lower depth = faster queries
3. **Select specific fields** - Don't fetch what you don't need
4. **Use pagination** - Never fetch all documents
5. **Avoid nested OR queries** - Can be slow on large collections
6. **Use count for totals** - Faster than fetching all docs

# Skill Creator
This skill provides guidance for creating effective skills.
## About Skills
Skills are modular, self-contained packages that extend Claude's capabilities by providing
specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific
domains or tasks—they transform Claude from a general-purpose agent into a specialized agent
equipped with procedural knowledge that no model can fully possess.
### What Skills Provide
1. Specialized workflows - Multi-step procedures for specific domains
2. Tool integrations - Instructions for working with specific file formats or APIs
3. Domain expertise - Company-specific knowledge, schemas, business logic
4. Bundled resources - Scripts, references, and assets for complex and repetitive tasks
## Core Principles
### Concise is Key
The context window is a public good. Skills share the context window with everything else Claude needs: system prompt, conversation history, other Skills' metadata, and the actual user request.
**Default assumption: Claude is already very smart.** Only add context Claude doesn't already have. Challenge each piece of information: "Does Claude really need this explanation?" and "Does this paragraph justify its token cost?"
Prefer concise examples over verbose explanations.
### Set Appropriate Degrees of Freedom
Match the level of specificity to the task's fragility and variability:
**High freedom (text-based instructions)**: Use when multiple approaches are valid, decisions depend on context, or heuristics guide the approach.
**Medium freedom (pseudocode or scripts with parameters)**: Use when a preferred pattern exists, some variation is acceptable, or configuration affects behavior.
**Low freedom (specific scripts, few parameters)**: Use when operations are fragile and error-prone, consistency is critical, or a specific sequence must be followed.
Think of Claude as exploring a path: a narrow bridge with cliffs needs specific guardrails (low freedom), while an open field allows many routes (high freedom).
### Anatomy of a Skill
Every skill consists of a required SKILL.md file and optional bundled resources:
```
skill-name/
├── SKILL.md (required)
│ ├── YAML frontmatter metadata (required)
│ │ ├── name: (required)
│ │ └── description: (required)
│ └── Markdown instructions (required)
└── Bundled Resources (optional)
├── scripts/ - Executable code (Python/Bash/etc.)
├── references/ - Documentation intended to be loaded into context as needed
└── assets/ - Files used in output (templates, icons, fonts, etc.)
```
#### SKILL.md (required)
Every SKILL.md consists of:
- **Frontmatter** (YAML): Contains `name` and `description` fields. These are the only fields that Claude reads to determine when the skill gets used, thus it is very important to be clear and comprehensive in describing what the skill is, and when it should be used.
- **Body** (Markdown): Instructions and guidance for using the skill. Only loaded AFTER the skill triggers (if at all).
#### Bundled Resources (optional)
##### Scripts (`scripts/`)
Executable code (Python/Bash/etc.) for tasks that require deterministic reliability or are repeatedly rewritten.
- **When to include**: When the same code is being rewritten repeatedly or deterministic reliability is needed
- **Example**: `scripts/rotate_pdf.py` for PDF rotation tasks
- **Benefits**: Token efficient, deterministic, may be executed without loading into context
- **Note**: Scripts may still need to be read by Claude for patching or environment-specific adjustments
##### References (`references/`)
Documentation and reference material intended to be loaded as needed into context to inform Claude's process and thinking.
- **When to include**: For documentation that Claude should reference while working
- **Examples**: `references/finance.md` for financial schemas, `references/mnda.md` for company NDA template, `references/policies.md` for company policies, `references/api_docs.md` for API specifications
- **Use cases**: Database schemas, API documentation, domain knowledge, company policies, detailed workflow guides
- **Benefits**: Keeps SKILL.md lean, loaded only when Claude determines it's needed
- **Best practice**: If files are large (>10k words), include grep search patterns in SKILL.md
- **Avoid duplication**: Information should live in either SKILL.md or references files, not both. Prefer references files for detailed information unless it's truly core to the skill—this keeps SKILL.md lean while making information discoverable without hogging the context window. Keep only essential procedural instructions and workflow guidance in SKILL.md; move detailed reference material, schemas, and examples to references files.
##### Assets (`assets/`)
Files not intended to be loaded into context, but rather used within the output Claude produces.
- **When to include**: When the skill needs files that will be used in the final output
- **Examples**: `assets/logo.png` for brand assets, `assets/slides.pptx` for PowerPoint templates, `assets/frontend-template/` for HTML/React boilerplate, `assets/font.ttf` for typography
- **Use cases**: Templates, images, icons, boilerplate code, fonts, sample documents that get copied or modified
- **Benefits**: Separates output resources from documentation, enables Claude to use files without loading them into context
#### What to Not Include in a Skill
A skill should only contain essential files that directly support its functionality. Do NOT create extraneous documentation or auxiliary files, including:
- README.md
- INSTALLATION_GUIDE.md
- QUICK_REFERENCE.md
- CHANGELOG.md
- etc.
The skill should only contain the information needed for an AI agent to do the job at hand. It should not contain auxilary context about the process that went into creating it, setup and testing procedures, user-facing documentation, etc. Creating additional documentation files just adds clutter and confusion.
### Progressive Disclosure Design Principle
Skills use a three-level loading system to manage context efficiently:
1. **Metadata (name + description)** - Always in context (~100 words)
2. **SKILL.md body** - When skill triggers (<5k words)
3. **Bundled resources** - As needed by Claude (Unlimited because scripts can be executed without reading into context window)
#### Progressive Disclosure Patterns
Keep SKILL.md body to the essentials and under 500 lines to minimize context bloat. Split content into separate files when approaching this limit. When splitting out content into other files, it is very important to reference them from SKILL.md and describe clearly when to read them, to ensure the reader of the skill knows they exist and when to use them.
**Key principle:** When a skill supports multiple variations, frameworks, or options, keep only the core workflow and selection guidance in SKILL.md. Move variant-specific details (patterns, examples, configuration) into separate reference files.
**Pattern 1: High-level guide with references**
```markdown
# PDF Processing
## Quick start
Extract text with pdfplumber:
[code example]
## Advanced features
- **Form filling**: See [FORMS.md](FORMS.md) for complete guide
- **API reference**: See [REFERENCE.md](REFERENCE.md) for all methods
- **Examples**: See [EXAMPLES.md](EXAMPLES.md) for common patterns
```
Claude loads FORMS.md, REFERENCE.md, or EXAMPLES.md only when needed.
**Pattern 2: Domain-specific organization**
For Skills with multiple domains, organize content by domain to avoid loading irrelevant context:
```
bigquery-skill/
├── SKILL.md (overview and navigation)
└── reference/
├── finance.md (revenue, billing metrics)
├── sales.md (opportunities, pipeline)
├── product.md (API usage, features)
└── marketing.md (campaigns, attribution)
```
When a user asks about sales metrics, Claude only reads sales.md.
Similarly, for skills supporting multiple frameworks or variants, organize by variant:
```
cloud-deploy/
├── SKILL.md (workflow + provider selection)
└── references/
├── aws.md (AWS deployment patterns)
├── gcp.md (GCP deployment patterns)
└── azure.md (Azure deployment patterns)
```
When the user chooses AWS, Claude only reads aws.md.
**Pattern 3: Conditional details**
Show basic content, link to advanced content:
```markdown
# DOCX Processing
## Creating documents
Use docx-js for new documents. See [DOCX-JS.md](DOCX-JS.md).
## Editing documents
For simple edits, modify the XML directly.
**For tracked changes**: See [REDLINING.md](REDLINING.md)
**For OOXML details**: See [OOXML.md](OOXML.md)
```
Claude reads REDLINING.md or OOXML.md only when the user needs those features.
**Important guidelines:**
- **Avoid deeply nested references** - Keep references one level deep from SKILL.md. All reference files should link directly from SKILL.md.
- **Structure longer reference files** - For files longer than 100 lines, include a table of contents at the top so Claude can see the full scope when previewing.
## Skill Creation Process
Skill creation involves these steps:
1. Understand the skill with concrete examples
2. Plan reusable skill contents (scripts, references, assets)
3. Initialize the skill (run init_skill.py)
4. Edit the skill (implement resources and write SKILL.md)
5. Package the skill (run package_skill.py)
6. Iterate based on real usage
Follow these steps in order, skipping only if there is a clear reason why they are not applicable.
### Step 1: Understanding the Skill with Concrete Examples
Skip this step only when the skill's usage patterns are already clearly understood. It remains valuable even when working with an existing skill.
To create an effective skill, clearly understand concrete examples of how the skill will be used. This understanding can come from either direct user examples or generated examples that are validated with user feedback.
For example, when building an image-editor skill, relevant questions include:
- "What functionality should the image-editor skill support? Editing, rotating, anything else?"
- "Can you give some examples of how this skill would be used?"
- "I can imagine users asking for things like 'Remove the red-eye from this image' or 'Rotate this image'. Are there other ways you imagine this skill being used?"
- "What would a user say that should trigger this skill?"
To avoid overwhelming users, avoid asking too many questions in a single message. Start with the most important questions and follow up as needed for better effectiveness.
Conclude this step when there is a clear sense of the functionality the skill should support.
### Step 2: Planning the Reusable Skill Contents
To turn concrete examples into an effective skill, analyze each example by:
1. Considering how to execute on the example from scratch
2. Identifying what scripts, references, and assets would be helpful when executing these workflows repeatedly
Example: When building a `pdf-editor` skill to handle queries like "Help me rotate this PDF," the analysis shows:
1. Rotating a PDF requires re-writing the same code each time
2. A `scripts/rotate_pdf.py` script would be helpful to store in the skill
Example: When designing a `frontend-webapp-builder` skill for queries like "Build me a todo app" or "Build me a dashboard to track my steps," the analysis shows:
1. Writing a frontend webapp requires the same boilerplate HTML/React each time
2. An `assets/hello-world/` template containing the boilerplate HTML/React project files would be helpful to store in the skill
Example: When building a `big-query` skill to handle queries like "How many users have logged in today?" the analysis shows:
1. Querying BigQuery requires re-discovering the table schemas and relationships each time
2. A `references/schema.md` file documenting the table schemas would be helpful to store in the skill
To establish the skill's contents, analyze each concrete example to create a list of the reusable resources to include: scripts, references, and assets.
### Step 3: Initializing the Skill
At this point, it is time to actually create the skill.
Skip this step only if the skill being developed already exists, and iteration or packaging is needed. In this case, continue to the next step.
When creating a new skill from scratch, always run the `init_skill.py` script. The script conveniently generates a new template skill directory that automatically includes everything a skill requires, making the skill creation process much more efficient and reliable.
Usage:
```bash
scripts/init_skill.py <skill-name> --path <output-directory>
```
The script:
- Creates the skill directory at the specified path
- Generates a SKILL.md template with proper frontmatter and TODO placeholders
- Creates example resource directories: `scripts/`, `references/`, and `assets/`
- Adds example files in each directory that can be customized or deleted
After initialization, customize or remove the generated SKILL.md and example files as needed.
### Step 4: Edit the Skill
When editing the (newly-generated or existing) skill, remember that the skill is being created for another instance of Claude to use. Include information that would be beneficial and non-obvious to Claude. Consider what procedural knowledge, domain-specific details, or reusable assets would help another Claude instance execute these tasks more effectively.
#### Learn Proven Design Patterns
Consult these helpful guides based on your skill's needs:
- **Multi-step processes**: See references/workflows.md for sequential workflows and conditional logic
- **Specific output formats or quality standards**: See references/output-patterns.md for template and example patterns
These files contain established best practices for effective skill design.
#### Start with Reusable Skill Contents
To begin implementation, start with the reusable resources identified above: `scripts/`, `references/`, and `assets/` files. Note that this step may require user input. For example, when implementing a `brand-guidelines` skill, the user may need to provide brand assets or templates to store in `assets/`, or documentation to store in `references/`.
Added scripts must be tested by actually running them to ensure there are no bugs and that the output matches what is expected. If there are many similar scripts, only a representative sample needs to be tested to ensure confidence that they all work while balancing time to completion.
Any example files and directories not needed for the skill should be deleted. The initialization script creates example files in `scripts/`, `references/`, and `assets/` to demonstrate structure, but most skills won't need all of them.
#### Update SKILL.md
**Writing Guidelines:** Always use imperative/infinitive form.
##### Frontmatter
Write the YAML frontmatter with `name` and `description`:
- `name`: The skill name
- `description`: This is the primary triggering mechanism for your skill, and helps Claude understand when to use the skill.
- Include both what the Skill does and specific triggers/contexts for when to use it.
- Include all "when to use" information here - Not in the body. The body is only loaded after triggering, so "When to Use This Skill" sections in the body are not helpful to Claude.
- Example description for a `docx` skill: "Comprehensive document creation, editing, and analysis with support for tracked changes, comments, formatting preservation, and text extraction. Use when Claude needs to work with professional documents (.docx files) for: (1) Creating new documents, (2) Modifying or editing content, (3) Working with tracked changes, (4) Adding comments, or any other document tasks"
Do not include any other fields in YAML frontmatter.
##### Body
Write instructions for using the skill and its bundled resources.
### Step 5: Packaging a Skill
Once development of the skill is complete, it must be packaged into a distributable .skill file that gets shared with the user. The packaging process automatically validates the skill first to ensure it meets all requirements:
```bash
scripts/package_skill.py <path/to/skill-folder>
```
Optional output directory specification:
```bash
scripts/package_skill.py <path/to/skill-folder> ./dist
```
The packaging script will:
1. **Validate** the skill automatically, checking:
- YAML frontmatter format and required fields
- Skill naming conventions and directory structure
- Description completeness and quality
- File organization and resource references
2. **Package** the skill if validation passes, creating a .skill file named after the skill (e.g., `my-skill.skill`) that includes all files and maintains the proper directory structure for distribution. The .skill file is a zip file with a .skill extension.
If validation fails, the script will report the errors and exit without creating a package. Fix any validation errors and run the packaging command again.
### Step 6: Iterate
After testing the skill, users may request improvements. Often this happens right after using the skill, with fresh context of how the skill performed.
**Iteration workflow:**
1. Use the skill on real tasks
2. Notice struggles or inefficiencies
3. Identify how SKILL.md or bundled resources should be updated
4. Implement changes and test again

# Output Patterns
Use these patterns when skills need to produce consistent, high-quality output.
## Template Pattern
Provide templates for output format. Match the level of strictness to your needs.
**For strict requirements (like API responses or data formats):**
```markdown
## Report structure
ALWAYS use this exact template structure:
# [Analysis Title]
## Executive summary
[One-paragraph overview of key findings]
## Key findings
- Finding 1 with supporting data
- Finding 2 with supporting data
- Finding 3 with supporting data
## Recommendations
1. Specific actionable recommendation
2. Specific actionable recommendation
```
**For flexible guidance (when adaptation is useful):**
```markdown
## Report structure
Here is a sensible default format, but use your best judgment:
# [Analysis Title]
## Executive summary
[Overview]
## Key findings
[Adapt sections based on what you discover]
## Recommendations
[Tailor to the specific context]
Adjust sections as needed for the specific analysis type.
```
## Examples Pattern
For skills where output quality depends on seeing examples, provide input/output pairs:
```markdown
## Commit message format
Generate commit messages following these examples:
**Example 1:**
Input: Added user authentication with JWT tokens
Output:
```
feat(auth): implement JWT-based authentication
Add login endpoint and token validation middleware
```
**Example 2:**
Input: Fixed bug where dates displayed incorrectly in reports
Output:
```
fix(reports): correct date formatting in timezone conversion
Use UTC timestamps consistently across report generation
```
Follow this style: type(scope): brief description, then detailed explanation.
```
Examples help Claude understand the desired style and level of detail more clearly than descriptions alone.

# Workflow Patterns
## Sequential Workflows
For complex tasks, break operations into clear, sequential steps. It is often helpful to give Claude an overview of the process towards the beginning of SKILL.md:
```markdown
Filling a PDF form involves these steps:
1. Analyze the form (run analyze_form.py)
2. Create field mapping (edit fields.json)
3. Validate mapping (run validate_fields.py)
4. Fill the form (run fill_form.py)
5. Verify output (run verify_output.py)
```
## Conditional Workflows
For tasks with branching logic, guide Claude through decision points:
```markdown
1. Determine the modification type:
**Creating new content?** → Follow "Creation workflow" below
**Editing existing content?** → Follow "Editing workflow" below
2. Creation workflow: [steps]
3. Editing workflow: [steps]
```

# {skill_title}
## Overview
[TODO: 1-2 sentences explaining what this skill enables]
## Structuring This Skill
[TODO: Choose the structure that best fits this skill's purpose. Common patterns:
**1. Workflow-Based** (best for sequential processes)
- Works well when there are clear step-by-step procedures
- Example: DOCX skill with "Workflow Decision Tree""Reading""Creating""Editing"
- Structure: ## Overview → ## Workflow Decision Tree → ## Step 1 → ## Step 2...
**2. Task-Based** (best for tool collections)
- Works well when the skill offers different operations/capabilities
- Example: PDF skill with "Quick Start""Merge PDFs""Split PDFs""Extract Text"
- Structure: ## Overview → ## Quick Start → ## Task Category 1 → ## Task Category 2...
**3. Reference/Guidelines** (best for standards or specifications)
- Works well for brand guidelines, coding standards, or requirements
- Example: Brand styling with "Brand Guidelines""Colors""Typography""Features"
- Structure: ## Overview → ## Guidelines → ## Specifications → ## Usage...
**4. Capabilities-Based** (best for integrated systems)
- Works well when the skill provides multiple interrelated features
- Example: Product Management with "Core Capabilities" → numbered capability list
- Structure: ## Overview → ## Core Capabilities → ### 1. Feature → ### 2. Feature...
Patterns can be mixed and matched as needed. Most skills combine patterns (e.g., start with task-based, add workflow for complex operations).
Delete this entire "Structuring This Skill" section when done - it's just guidance.]
## [TODO: Replace with the first main section based on chosen structure]
[TODO: Add content here. See examples in existing skills:
- Code samples for technical skills
- Decision trees for complex workflows
- Concrete examples with realistic user requests
- References to scripts/templates/references as needed]
## Resources
This skill includes example resource directories that demonstrate how to organize different types of bundled resources:
### scripts/
Executable code (Python/Bash/etc.) that can be run directly to perform specific operations.
**Examples from other skills:**
- PDF skill: `fill_fillable_fields.py`, `extract_form_field_info.py` - utilities for PDF manipulation
- DOCX skill: `document.py`, `utilities.py` - Python modules for document processing
**Appropriate for:** Python scripts, shell scripts, or any executable code that performs automation, data processing, or specific operations.
**Note:** Scripts may be executed without loading into context, but can still be read by Claude for patching or environment adjustments.
### references/
Documentation and reference material intended to be loaded into context to inform Claude's process and thinking.
**Examples from other skills:**
- Product management: `communication.md`, `context_building.md` - detailed workflow guides
- BigQuery: API reference documentation and query examples
- Finance: Schema documentation, company policies
**Appropriate for:** In-depth documentation, API references, database schemas, comprehensive guides, or any detailed information that Claude should reference while working.
### assets/
Files not intended to be loaded into context, but rather used within the output Claude produces.
**Examples from other skills:**
- Brand styling: PowerPoint template files (.pptx), logo files
- Frontend builder: HTML/React boilerplate project directories
- Typography: Font files (.ttf, .woff2)
**Appropriate for:** Templates, boilerplate code, document templates, images, icons, fonts, or any files meant to be copied or used in the final output.

name: tailwindcss
description: Tailwind CSS utility-first styling for JARVIS UI components
model: sonnet
risk_level: LOW
version: 1.1.0
---
# Tailwind CSS Development Skill
> **File Organization**: This skill uses split structure. See `references/` for advanced patterns.
## 1. Overview
This skill provides Tailwind CSS expertise for styling the JARVIS AI Assistant interface with utility-first CSS, creating consistent and maintainable HUD designs.
**Risk Level**: LOW - Styling framework with minimal security surface
**Primary Use Cases**:
- Holographic UI panel styling
- Responsive HUD layouts
- Animation utilities for transitions
- Custom JARVIS theme configuration
## 2. Core Responsibilities
### 2.1 Fundamental Principles
1. **TDD First**: Write component tests before styling implementation
2. **Performance Aware**: Optimize CSS output size and rendering performance
3. **Utility-First**: Compose styles from utility classes, extract components when patterns repeat
4. **Design System**: Define JARVIS color palette and spacing in config
5. **Responsive Design**: Mobile-first with breakpoint utilities
6. **Dark Mode Default**: HUD is always dark-themed
7. **Accessibility**: Maintain sufficient contrast ratios
## 3. Implementation Workflow (TDD)
### 3.1 TDD Process for Styled Components
Follow this workflow for every styled component:
#### Step 1: Write Failing Test First
```typescript
// tests/components/HUDPanel.test.ts
import { describe, it, expect } from 'vitest'
import { mount } from '@vue/test-utils'
import HUDPanel from '~/components/HUDPanel.vue'
describe('HUDPanel', () => {
it('renders with correct JARVIS theme classes', () => {
const wrapper = mount(HUDPanel, {
props: { title: 'System Status' }
})
const panel = wrapper.find('[data-testid="hud-panel"]')
expect(panel.classes()).toContain('bg-jarvis-bg-panel/80')
expect(panel.classes()).toContain('border-jarvis-primary/30')
expect(panel.classes()).toContain('backdrop-blur-sm')
})
it('applies responsive grid layout', () => {
const wrapper = mount(HUDPanel)
const grid = wrapper.find('[data-testid="panel-grid"]')
expect(grid.classes()).toContain('grid-cols-1')
expect(grid.classes()).toContain('md:grid-cols-2')
expect(grid.classes()).toContain('lg:grid-cols-3')
})
it('shows correct status indicator colors', async () => {
const wrapper = mount(HUDPanel, {
props: { status: 'active' }
})
const indicator = wrapper.find('[data-testid="status-indicator"]')
expect(indicator.classes()).toContain('bg-jarvis-primary')
expect(indicator.classes()).toContain('animate-pulse')
await wrapper.setProps({ status: 'error' })
expect(indicator.classes()).toContain('bg-jarvis-danger')
})
it('maintains accessibility focus styles', () => {
const wrapper = mount(HUDPanel)
const button = wrapper.find('button')
expect(button.classes()).toContain('focus:ring-2')
expect(button.classes()).toContain('focus:outline-none')
})
})
```
#### Step 2: Implement Minimum to Pass
```vue
<!-- components/HUDPanel.vue -->
<template>
<div
data-testid="hud-panel"
class="bg-jarvis-bg-panel/80 border border-jarvis-primary/30 backdrop-blur-sm rounded-lg p-4"
>
<div
data-testid="panel-grid"
class="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-4"
>
<slot />
</div>
<span
data-testid="status-indicator"
:class="statusClasses"
/>
<button class="focus:ring-2 focus:outline-none focus:ring-jarvis-primary">
Action
</button>
</div>
</template>
<script setup lang="ts">
import { computed } from 'vue'
const props = defineProps<{
title?: string
status?: 'active' | 'warning' | 'error' | 'inactive'
}>()
const statusClasses = computed(() => ({
'bg-jarvis-primary animate-pulse': props.status === 'active',
'bg-jarvis-warning': props.status === 'warning',
'bg-jarvis-danger': props.status === 'error',
'bg-gray-500': props.status === 'inactive'
}))
</script>
```
#### Step 3: Refactor if Needed
Extract repeated patterns to @apply directives:
```css
/* assets/css/components.css */
@layer components {
.hud-panel {
@apply bg-jarvis-bg-panel/80 border border-jarvis-primary/30 backdrop-blur-sm rounded-lg p-4;
}
.hud-grid {
@apply grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-4;
}
}
```
#### Step 4: Run Full Verification
```bash
# Run all style-related tests
npm run test -- --grep "HUDPanel"
# Check for unused CSS
npx tailwindcss --content './components/**/*.vue' --output /dev/null
# Verify build size
npm run build && ls -lh .output/public/_nuxt/*.css
```
## 4. Performance Patterns
### 4.1 Purge Optimization
```javascript
// tailwind.config.js
// Good: Specific content paths
export default {
content: [
'./components/**/*.{vue,js,ts}',
'./layouts/**/*.vue',
'./pages/**/*.vue',
'./composables/**/*.ts'
]
}
// Bad: Too broad, includes unused files
export default {
content: ['./src/**/*'] // Includes tests, stories, etc.
}
```
### 4.2 JIT Mode Efficiency
```javascript
// Good: Let JIT generate only used utilities
export default {
mode: 'jit', // Default in v3+
theme: {
extend: {
// Only extend what you need
colors: {
jarvis: {
primary: '#00ff41',
secondary: '#0891b2'
}
}
}
}
}
// Bad: Defining unused variants
export default {
variants: {
extend: {
backgroundColor: ['active', 'group-hover', 'disabled'] // May not use all
}
}
}
```
### 4.3 @apply Extraction Strategy
```vue
<!-- Good: Extract when pattern repeats 3+ times -->
<style>
@layer components {
.btn-jarvis {
@apply px-4 py-2 rounded font-medium transition-all duration-200
focus:outline-none focus:ring-2 focus:ring-offset-2;
}
}
</style>
<!-- Bad: @apply for single-use styles -->
<style>
.my-unique-element {
@apply p-4 m-2 text-white; /* Just use utilities in template */
}
</style>
```
### 4.4 Responsive Breakpoints Efficiency
```vue
<!-- Good: Mobile-first, minimal breakpoints -->
<div class="p-2 md:p-4 lg:p-6">
<div class="grid grid-cols-1 md:grid-cols-2 xl:grid-cols-4">
</div>
<!-- Bad: Redundant breakpoint definitions -->
<div class="p-2 sm:p-2 md:p-4 lg:p-4 xl:p-6">
<div class="grid grid-cols-1 sm:grid-cols-1 md:grid-cols-2 lg:grid-cols-2">
</div>
```
### 4.5 Dark Mode Efficiency
```javascript
// Good: Single dark mode strategy (JARVIS is always dark)
export default {
darkMode: 'class', // Use 'class' for explicit control
theme: {
extend: {
colors: {
jarvis: {
bg: {
dark: '#0a0a0f', // Define dark colors directly
panel: '#111827'
}
}
}
}
}
}
// Bad: Light/dark variants when app is always dark
<div class="bg-white dark:bg-gray-900"> // Unnecessary light styles
```
### 4.6 Animation Performance
```javascript
// Good: GPU-accelerated properties
export default {
theme: {
extend: {
keyframes: {
glow: {
'0%, 100%': { opacity: '0.5' }, // opacity is GPU-accelerated
'50%': { opacity: '1' }
}
}
}
}
}
// Bad: Layout-triggering properties
keyframes: {
resize: {
'0%': { width: '100px' }, // Triggers layout recalc
'100%': { width: '200px' }
}
}
```

## 6. Implementation Patterns
### 6.1 HUD Panel Component
```vue
<template>
<div class="
relative
bg-jarvis-bg-panel/80
border border-jarvis-primary/30
rounded-lg
p-4
backdrop-blur-sm
shadow-lg shadow-jarvis-primary/10
">
<!-- Scanline overlay -->
<div class="
absolute inset-0
bg-gradient-to-b from-transparent via-jarvis-primary/5 to-transparent
animate-scan
pointer-events-none
" />
<!-- Content -->
<div class="relative z-10">
<h3 class="
font-display
text-jarvis-primary
text-lg
uppercase
tracking-wider
mb-2
">
{{ title }}
</h3>
<slot />
</div>
</div>
</template>
```
### 6.2 Status Indicator
```vue
<template>
<div class="flex items-center gap-2">
<span :class="[
'w-2 h-2 rounded-full',
{
'bg-jarvis-primary animate-pulse': status === 'active',
'bg-jarvis-warning': status === 'warning',
'bg-jarvis-danger animate-ping': status === 'error',
'bg-gray-500': status === 'inactive'
}
]" />
<span class="text-sm text-gray-300">{{ label }}</span>
</div>
</template>
```
### 6.3 Button Variants
```vue
<template>
<button :class="[
'px-4 py-2 rounded font-medium transition-all duration-200',
'focus:outline-none focus:ring-2 focus:ring-offset-2 focus:ring-offset-jarvis-bg-dark',
{
'bg-jarvis-primary text-black hover:bg-jarvis-primary/90 focus:ring-jarvis-primary':
variant === 'primary',
'bg-transparent border border-jarvis-secondary text-jarvis-secondary hover:bg-jarvis-secondary/10 focus:ring-jarvis-secondary':
variant === 'secondary',
'bg-jarvis-danger text-white hover:bg-jarvis-danger/90 focus:ring-jarvis-danger':
variant === 'danger'
}
]">
<slot />
</button>
</template>
```
## 7. Quality Standards
### 7.1 Accessibility
```vue
<!-- Good - Sufficient contrast -->
<span class="text-jarvis-primary"><!-- #00ff41 on dark bg --></span>
<!-- Good - Focus visible -->
<button class="focus:ring-2 focus:ring-jarvis-primary focus:outline-none">
<!-- Good - Screen reader text -->
<span class="sr-only">Status: Active</span>
```
## 8. Common Mistakes & Anti-Patterns
### 8.1 Anti-Patterns
#### Avoid: Excessive Custom CSS
```vue
<!-- Bad - Custom CSS when utilities exist -->
<style>
.custom-panel {
padding: 1rem;
border-radius: 0.5rem;
}
</style>
<!-- Good - Use utilities -->
<div class="p-4 rounded-lg">
```
#### Avoid: Inconsistent Spacing
```vue
<!-- Bad - Mixed spacing values -->
<div class="p-3 mt-5 mb-2">
<!-- Good - Consistent scale -->
<div class="p-4 my-4">
```
#### Avoid: Hardcoded Colors
```vue
<!-- Bad - Hardcoded hex -->
<div class="text-[#00ff41]">
<!-- Good - Theme color -->
<div class="text-jarvis-primary">
```
## 9. Pre-Implementation Checklist
### Phase 1: Before Writing Code
- [ ] Write component tests for expected class applications
- [ ] Verify JARVIS theme colors are defined in config
- [ ] Check content paths include all source files
- [ ] Review existing components for reusable patterns
### Phase 2: During Implementation
- [ ] Use utilities before custom CSS
- [ ] Apply consistent spacing scale (4, 8, 12, 16...)
- [ ] Include focus states for all interactive elements
- [ ] Test responsive breakpoints at each size
- [ ] Use theme colors, never hardcoded hex values
### Phase 3: Before Committing
- [ ] All component tests pass: `npm test`
- [ ] Build completes without CSS errors: `npm run build`
- [ ] Check CSS bundle size hasn't grown unexpectedly
- [ ] Verify no unused @apply extractions
- [ ] Test accessibility with keyboard navigation
## 10. Summary
Tailwind CSS provides utility-first styling for JARVIS:
1. **TDD**: Write tests for class applications before implementation
2. **Performance**: Optimize content paths and use JIT mode
3. **Theme**: Define JARVIS colors and fonts in config
4. **Utilities**: Compose styles from utilities, extract patterns with @apply
5. **Accessibility**: Maintain focus states and sufficient contrast
**Remember**: The JARVIS HUD has a distinct visual identity - maintain consistency with the theme configuration and test all styling with vitest.

</div>
<!-- Right sidebar -->
<div class="col-span-3 space-y-4">
<MetricsPanel />
<AlertsPanel />
</div>
</div>
</template>
```
## Custom Animations
### Glitch Effect
```javascript
// tailwind.config.js
animation: {
'glitch': 'glitch 1s infinite linear alternate-reverse',
'glitch-1': 'glitch-1 0.8s infinite linear alternate-reverse',
'glitch-2': 'glitch-2 0.9s infinite linear alternate-reverse'
},
keyframes: {
glitch: {
'0%, 100%': { transform: 'translate(0)' },
'20%': { transform: 'translate(-2px, 2px)' },
'40%': { transform: 'translate(-2px, -2px)' },
'60%': { transform: 'translate(2px, 2px)' },
'80%': { transform: 'translate(2px, -2px)' }
},
'glitch-1': {
'0%, 100%': { clipPath: 'inset(0 0 0 0)' },
'50%': { clipPath: 'inset(5% 0 80% 0)' }
}
}
```
## Responsive HUD
```vue
<template>
<div class="
flex
flex-col md:flex-row
gap-4
p-2 md:p-4
">
<!-- Collapses on mobile -->
<aside class="
w-full md:w-64
flex md:flex-col
gap-2
overflow-x-auto md:overflow-visible
">
<MiniPanel v-for="panel in panels" :key="panel.id" />
</aside>
<!-- Main content expands -->
<main class="flex-1 min-h-[300px] md:min-h-[500px]">
<slot />
</main>
</div>
</template>
```
## Plugin: Holographic Glow
```javascript
// plugins/holographic.js
const plugin = require('tailwindcss/plugin')
module.exports = plugin(function({ addUtilities, theme }) {
const glows = {}
Object.entries(theme('colors.jarvis')).forEach(([name, color]) => {
if (typeof color === 'string') {
glows[`.glow-${name}`] = {
boxShadow: `0 0 10px ${color}, 0 0 20px ${color}40, 0 0 30px ${color}20`
}
glows[`.text-glow-${name}`] = {
textShadow: `0 0 10px ${color}`
}
}
})
addUtilities(glows)

description: Verify task completion across multi-agent projects through structured reflection. Use when (1) reviewing another agent's work before merging or handoff, (2) validating your own task completion before reporting done, (3) performing quality assurance on completed deliverables, (4) generating completion reports for stakeholders, or (5) checking if all success criteria have been met.

# Task Review
Structured reflection to verify task completion, maintain focus, and prevent context rot.
## Purpose
As context grows, agents tend to drift from original intent. This skill provides checkpoints to:
- **Reflect** on what was asked vs what's being done
- **Realign** attention to the core objective
- **Verify** completion against success criteria
## Quick Reflection
Ask these questions at any point:
1. **What was I asked to do?** (Original intent)
2. **What have I done so far?** (Current state)
3. **Am I still on track?** (Alignment check)
4. **What's left?** (Remaining work)
## Reflection Workflow
### Step 1: Recall Original Intent
Before proceeding, explicitly state:
- **The ask**: What did the user/requester actually want?
- **Success looks like**: How will we know it's done?
- **Scope boundaries**: What's included? What's explicitly NOT included?
> [!TIP]
> If you can't clearly state the original intent, context rot may have occurred. Go back to the original request.
### Step 2: Audit Current State
List what has been accomplished:
| Action Taken | Relates to Original Ask? | Still Relevant? |
|--------------|--------------------------|-----------------|
| [action 1] | ✅ / ⚠️ / ❌ | Yes / No |
| [action 2] | ✅ / ⚠️ / ❌ | Yes / No |
**Signs of drift:**
- Actions that don't map to the original ask
- Rabbit holes pursued without clear purpose
- Scope creep beyond initial boundaries
### Step 3: Refocus Attention
If drift detected, course-correct:
1. **Stop** - Pause current activity
2. **Summarize** - What's the core objective in one sentence?
3. **Prioritize** - What's the single most important next step?
4. **Resume** - Continue with renewed focus
### Step 4: Verify Completion
Before marking done:
```
□ Original intent addressed
□ All stated success criteria met
□ No critical gaps remain
□ Result is usable/actionable
```
## Completion Status
**COMPLETE** - Original intent fully addressed, success criteria met
**NEEDS WORK** - Partial progress, clear gaps remain
**BLOCKED** - Cannot proceed without external input
**OFF TRACK** - Significant drift, needs re-planning
## Reflection Report Template
```markdown
# Task Reflection
## Original Intent
[What was asked, in one sentence]
## Success Criteria
- [ ] Criterion 1
- [ ] Criterion 2
## Current State
[Brief summary of what's been done]
## Alignment Check
- On track: [Yes/No/Partially]
- Drift detected: [None/Minor/Significant]
## Status: [COMPLETE | NEEDS WORK | BLOCKED | OFF TRACK]
## Next Actions
- [If not complete, what's next]
```
## When to Reflect
Use this skill:
- **Before starting** - Clarify intent upfront
- **Mid-task checkpoint** - Every 5-10 actions, pause and reflect
- **Before reporting done** - Final verification
- **When confused** - Lost track of what you're doing
- **After errors** - Something went wrong, reassess
## Cross-Agent Handoff
When reviewing another agent's work:
1. **Read their stated intent** - What did they think they were doing?
2. **Compare to original ask** - Did they understand correctly?
3. **Verify their claims** - Did they actually do what they said?
4. **Check for gaps** - What might they have missed?

# Turborepo Skill
Build system for JavaScript/TypeScript monorepos. Turborepo caches task outputs and runs tasks in parallel based on dependency graph.
## IMPORTANT: Package Tasks, Not Root Tasks
**DO NOT create Root Tasks. ALWAYS create package tasks.**
When creating tasks/scripts/pipelines, you MUST:
1. Add the script to each relevant package's `package.json`
2. Register the task in root `turbo.json`
3. Root `package.json` only delegates via `turbo run <task>`
**DO NOT** put task logic in root `package.json`. This defeats Turborepo's parallelization.
```json
// DO THIS: Scripts in each package
// apps/web/package.json
{ "scripts": { "build": "next build", "lint": "eslint .", "test": "vitest" } }
// apps/api/package.json
{ "scripts": { "build": "tsc", "lint": "eslint .", "test": "vitest" } }
// packages/ui/package.json
{ "scripts": { "build": "tsc", "lint": "eslint .", "test": "vitest" } }
```
```json
// turbo.json - register tasks
{
"tasks": {
"build": { "dependsOn": ["^build"], "outputs": ["dist/**"] },
"lint": {},
"test": { "dependsOn": ["build"] }
}
}
```
```json
// Root package.json - ONLY delegates, no task logic
{
"scripts": {
"build": "turbo run build",
"lint": "turbo run lint",
"test": "turbo run test"
}
}
```
```json
// DO NOT DO THIS - defeats parallelization
// Root package.json
{
"scripts": {
"build": "cd apps/web && next build && cd ../api && tsc",
"lint": "eslint apps/ packages/",
"test": "vitest"
}
}
```
Root Tasks (`//#taskname`) are ONLY for tasks that truly cannot exist in packages (rare).
## Secondary Rule: `turbo run` vs `turbo`
**Always use `turbo run` when the command is written into code:**
```json
// package.json - ALWAYS "turbo run"
{
"scripts": {
"build": "turbo run build"
}
}
```
```yaml
# CI workflows - ALWAYS "turbo run"
- run: turbo run build --affected
```
**The shorthand `turbo <tasks>` is ONLY for one-off terminal commands** typed directly by humans or agents. Never write `turbo build` into package.json, CI, or scripts.
## Quick Decision Trees
### "I need to configure a task"
```
Configure a task?
├─ Define task dependencies → references/configuration/tasks.md
├─ Lint/check-types (parallel + caching) → Use Transit Nodes pattern (see below)
├─ Specify build outputs → references/configuration/tasks.md#outputs
├─ Handle environment variables → references/environment/README.md
├─ Set up dev/watch tasks → references/configuration/tasks.md#persistent
├─ Package-specific config → references/configuration/README.md#package-configurations
└─ Global settings (cacheDir, daemon) → references/configuration/global-options.md
```
### "My cache isn't working"
```
Cache problems?
├─ Tasks run but outputs not restored → Missing `outputs` key
├─ Cache misses unexpectedly → references/caching/gotchas.md
├─ Need to debug hash inputs → Use --summarize or --dry
├─ Want to skip cache entirely → Use --force or cache: false
├─ Remote cache not working → references/caching/remote-cache.md
└─ Environment causing misses → references/environment/gotchas.md
```
### "I want to run only changed packages"
```
Run only what changed?
├─ Changed packages + dependents (RECOMMENDED) → turbo run build --affected
├─ Custom base branch → --affected --affected-base=origin/develop
├─ Manual git comparison → --filter=...[origin/main]
└─ See all filter options → references/filtering/README.md
```
**`--affected` is the primary way to run only changed packages.** It automatically compares against the default branch and includes dependents.
### "I want to filter packages"
```
Filter packages?
├─ Only changed packages → --affected (see above)
├─ By package name → --filter=web
├─ By directory → --filter=./apps/*
├─ Package + dependencies → --filter=web...
├─ Package + dependents → --filter=...web
└─ Complex combinations → references/filtering/patterns.md
```
### "Environment variables aren't working"
```
Environment issues?
├─ Vars not available at runtime → Strict mode filtering (default)
├─ Cache hits with wrong env → Var not in `env` key
├─ .env changes not causing rebuilds → .env not in `inputs`
├─ CI variables missing → references/environment/gotchas.md
└─ Framework vars (NEXT_PUBLIC_*) → Auto-included via inference
```
### "I need to set up CI"
```
CI setup?
├─ GitHub Actions → references/ci/github-actions.md
├─ Vercel deployment → references/ci/vercel.md
├─ Remote cache in CI → references/caching/remote-cache.md
├─ Only build changed packages → --affected flag
├─ Skip unnecessary builds → turbo-ignore (references/cli/commands.md)
└─ Skip container setup when no changes → turbo-ignore
```
### "I want to watch for changes during development"
```
Watch mode?
├─ Re-run tasks on change → turbo watch (references/watch/README.md)
├─ Dev servers with dependencies → Use `with` key (references/configuration/tasks.md#with)
├─ Restart dev server on dep change → Use `interruptible: true`
└─ Persistent dev tasks → Use `persistent: true`
```
### "I need to create/structure a package"
```
Package creation/structure?
├─ Create an internal package → references/best-practices/packages.md
├─ Repository structure → references/best-practices/structure.md
├─ Dependency management → references/best-practices/dependencies.md
├─ Best practices overview → references/best-practices/README.md
├─ JIT vs Compiled packages → references/best-practices/packages.md#compilation-strategies
└─ Sharing code between apps → references/best-practices/README.md#package-types
```
### "How should I structure my monorepo?"
```
Monorepo structure?
├─ Standard layout (apps/, packages/) → references/best-practices/README.md
├─ Package types (apps vs libraries) → references/best-practices/README.md#package-types
├─ Creating internal packages → references/best-practices/packages.md
├─ TypeScript configuration → references/best-practices/structure.md#typescript-configuration
├─ ESLint configuration → references/best-practices/structure.md#eslint-configuration
├─ Dependency management → references/best-practices/dependencies.md
└─ Enforce package boundaries → references/boundaries/README.md
```
### "I want to enforce architectural boundaries"
```
Enforce boundaries?
├─ Check for violations → turbo boundaries
├─ Tag packages → references/boundaries/README.md#tags
├─ Restrict which packages can import others → references/boundaries/README.md#rule-types
└─ Prevent cross-package file imports → references/boundaries/README.md
```
## Critical Anti-Patterns
### Using `turbo` Shorthand in Code
**`turbo run` is recommended in package.json scripts and CI pipelines.** The shorthand `turbo <task>` is intended for interactive terminal use.
```json
// WRONG - using shorthand in package.json
{
"scripts": {
"build": "turbo build",
"dev": "turbo dev"
}
}
// CORRECT
{
"scripts": {
"build": "turbo run build",
"dev": "turbo run dev"
}
}
```
```yaml
# WRONG - using shorthand in CI
- run: turbo build --affected
# CORRECT
- run: turbo run build --affected
```
### Root Scripts Bypassing Turbo
Root `package.json` scripts MUST delegate to `turbo run`, not run tasks directly.
```json
// WRONG - bypasses turbo entirely
{
"scripts": {
"build": "bun build",
"dev": "bun dev"
}
}
// CORRECT - delegates to turbo
{
"scripts": {
"build": "turbo run build",
"dev": "turbo run dev"
}
}
```
### Using `&&` to Chain Turbo Tasks
Don't chain turbo tasks with `&&`. Let turbo orchestrate.
```json
// WRONG - turbo task not using turbo run
{
"scripts": {
"changeset:publish": "bun build && changeset publish"
}
}
// CORRECT
{
"scripts": {
"changeset:publish": "turbo run build && changeset publish"
}
}
```
### `prebuild` Scripts That Manually Build Dependencies
Scripts like `prebuild` that manually build other packages bypass Turborepo's dependency graph.
```json
// WRONG - manually building dependencies
{
"scripts": {
"prebuild": "cd ../../packages/types && bun run build && cd ../utils && bun run build",
"build": "next build"
}
}
```
**However, the fix depends on whether workspace dependencies are declared:**
1. **If dependencies ARE declared** (e.g., `"@repo/types": "workspace:*"` in package.json), remove the `prebuild` script. Turbo's `dependsOn: ["^build"]` handles this automatically.
2. **If dependencies are NOT declared**, the `prebuild` exists because `^build` won't trigger without a dependency relationship. The fix is to:
- Add the dependency to package.json: `"@repo/types": "workspace:*"`
- Then remove the `prebuild` script
```json
// CORRECT - declare dependency, let turbo handle build order
// package.json
{
"dependencies": {
"@repo/types": "workspace:*",
"@repo/utils": "workspace:*"
},
"scripts": {
"build": "next build"
}
}
// turbo.json
{
"tasks": {
"build": {
"dependsOn": ["^build"]
}
}
}
```
**Key insight:** `^build` only runs build in packages listed as dependencies. No dependency declaration = no automatic build ordering.
### Overly Broad `globalDependencies`
`globalDependencies` affects ALL tasks in ALL packages. Be specific.
```json
// WRONG - heavy hammer, affects all hashes
{
"globalDependencies": ["**/.env.*local"]
}
// BETTER - move to task-level inputs
{
"globalDependencies": [".env"],
"tasks": {
"build": {
"inputs": ["$TURBO_DEFAULT$", ".env*"],
"outputs": ["dist/**"]
}
}
}
```
### Repetitive Task Configuration
Look for repeated configuration across tasks that can be collapsed. Turborepo supports shared configuration patterns.
```json
// WRONG - repetitive env and inputs across tasks
{
"tasks": {
"build": {
"env": ["API_URL", "DATABASE_URL"],
"inputs": ["$TURBO_DEFAULT$", ".env*"]
},
"test": {
"env": ["API_URL", "DATABASE_URL"],
"inputs": ["$TURBO_DEFAULT$", ".env*"]
},
"dev": {
"env": ["API_URL", "DATABASE_URL"],
"inputs": ["$TURBO_DEFAULT$", ".env*"],
"cache": false,
"persistent": true
}
}
}
// BETTER - use globalEnv and globalDependencies for shared config
{
"globalEnv": ["API_URL", "DATABASE_URL"],
"globalDependencies": [".env*"],
"tasks": {
"build": {},
"test": {},
"dev": {
"cache": false,
"persistent": true
}
}
}
```
**When to use global vs task-level:**
- `globalEnv` / `globalDependencies` - affects ALL tasks, use for truly shared config
- Task-level `env` / `inputs` - use when only specific tasks need it
### NOT an Anti-Pattern: Large `env` Arrays
A large `env` array (even 50+ variables) is **not** a problem. It usually means the user was thorough about declaring their build's environment dependencies. Do not flag this as an issue.
### Using `--parallel` Flag
The `--parallel` flag bypasses Turborepo's dependency graph. If tasks need parallel execution, configure `dependsOn` correctly instead.
```bash
# WRONG - bypasses dependency graph
turbo run lint --parallel
# CORRECT - configure tasks to allow parallel execution
# In turbo.json, set dependsOn appropriately (or use transit nodes)
turbo run lint
```
### Package-Specific Task Overrides in Root turbo.json
When multiple packages need different task configurations, use **Package Configurations** (`turbo.json` in each package) instead of cluttering root `turbo.json` with `package#task` overrides.
```json
// WRONG - root turbo.json with many package-specific overrides
{
"tasks": {
"test": { "dependsOn": ["build"] },
"@repo/web#test": { "outputs": ["coverage/**"] },
"@repo/api#test": { "outputs": ["coverage/**"] },
"@repo/utils#test": { "outputs": [] },
"@repo/cli#test": { "outputs": [] },
"@repo/core#test": { "outputs": [] }
}
}
// CORRECT - use Package Configurations
// Root turbo.json - base config only
{
"tasks": {
"test": { "dependsOn": ["build"] }
}
}
// packages/web/turbo.json - package-specific override
{
"extends": ["//"],
"tasks": {
"test": { "outputs": ["coverage/**"] }
}
}
// packages/api/turbo.json
{
"extends": ["//"],
"tasks": {
"test": { "outputs": ["coverage/**"] }
}
}
```
**Benefits of Package Configurations:**
- Keeps configuration close to the code it affects
- Root turbo.json stays clean and focused on base patterns
- Easier to understand what's special about each package
- Works with `$TURBO_EXTENDS$` to inherit + extend arrays
**When to use `package#task` in root:**
- Single package needs a unique dependency (e.g., `"deploy": { "dependsOn": ["web#build"] }`)
- Temporary override while migrating
See `references/configuration/README.md#package-configurations` for full details.
### Using `../` to Traverse Out of Package in `inputs`
Don't use relative paths like `../` to reference files outside the package. Use `$TURBO_ROOT$` instead.
```json
// WRONG - traversing out of package
{
"tasks": {
"build": {
"inputs": ["$TURBO_DEFAULT$", "../shared-config.json"]
}
}
}
// CORRECT - use $TURBO_ROOT$ for repo root
{
"tasks": {
"build": {
"inputs": ["$TURBO_DEFAULT$", "$TURBO_ROOT$/shared-config.json"]
}
}
}
```
### Missing `outputs` for File-Producing Tasks
**Before flagging missing `outputs`, check what the task actually produces:**
1. Read the package's script (e.g., `"build": "tsc"`, `"test": "vitest"`)
2. Determine if it writes files to disk or only outputs to stdout
3. Only flag if the task produces files that should be cached
```json
// WRONG: build produces files but they're not cached
{
"tasks": {
"build": {
"dependsOn": ["^build"]
}
}
}
// CORRECT: build outputs are cached
{
"tasks": {
"build": {
"dependsOn": ["^build"],
"outputs": ["dist/**"]
}
}
}
```
Common outputs by framework:
- Next.js: `[".next/**", "!.next/cache/**"]`
- Vite/Rollup: `["dist/**"]`
- tsc: `["dist/**"]` or custom `outDir`
**TypeScript `--noEmit` can still produce cache files:**
When `incremental: true` in tsconfig.json, `tsc --noEmit` writes `.tsbuildinfo` files even without emitting JS. Check the tsconfig before assuming no outputs:
```json
// If tsconfig has incremental: true, tsc --noEmit produces cache files
{
"tasks": {
"typecheck": {
"outputs": ["node_modules/.cache/tsbuildinfo.json"] // or wherever tsBuildInfoFile points
}
}
}
```
To determine correct outputs for TypeScript tasks:
1. Check if `incremental` or `composite` is enabled in tsconfig
2. Check `tsBuildInfoFile` for custom cache location (default: alongside `outDir` or in project root)
3. If no incremental mode, `tsc --noEmit` produces no files
### `^build` vs `build` Confusion
```json
{
"tasks": {
// ^build = run build in DEPENDENCIES first (other packages this one imports)
"build": {
"dependsOn": ["^build"]
},
// build (no ^) = run build in SAME PACKAGE first
"test": {
"dependsOn": ["build"]
},
// pkg#task = specific package's task
"deploy": {
"dependsOn": ["web#build"]
}
}
}
```
### Environment Variables Not Hashed
```json
// WRONG: API_URL changes won't cause rebuilds
{
"tasks": {
"build": {
"outputs": ["dist/**"]
}
}
}
// CORRECT: API_URL changes invalidate cache
{
"tasks": {
"build": {
"outputs": ["dist/**"],
"env": ["API_URL", "API_KEY"]
}
}
}
```
### `.env` Files Not in Inputs
Turbo does NOT load `.env` files - your framework does. But Turbo needs to know about changes:
```json
// WRONG: .env changes don't invalidate cache
{
"tasks": {
"build": {
"env": ["API_URL"]
}
}
}
// CORRECT: .env file changes invalidate cache
{
"tasks": {
"build": {
"env": ["API_URL"],
"inputs": ["$TURBO_DEFAULT$", ".env", ".env.*"]
}
}
}
```
### Root `.env` File in Monorepo
A `.env` file at the repo root is an anti-pattern — even for small monorepos or starter templates. It creates implicit coupling between packages and makes it unclear which packages depend on which variables.
```
// WRONG - root .env affects all packages implicitly
my-monorepo/
├── .env # Which packages use this?
├── apps/
│ ├── web/
│ └── api/
└── packages/
// CORRECT - .env files in packages that need them
my-monorepo/
├── apps/
│ ├── web/
│ │ └── .env # Clear: web needs DATABASE_URL
│ └── api/
│ └── .env # Clear: api needs API_KEY
└── packages/
```
**Problems with root `.env`:**
- Unclear which packages consume which variables
- All packages get all variables (even ones they don't need)
- Cache invalidation is coarse-grained (root .env change invalidates everything)
- Security risk: packages may accidentally access sensitive vars meant for others
- Bad habits start small — starter templates should model correct patterns
**If you must share variables**, use `globalEnv` to be explicit about what's shared, and document why.
### Strict Mode Filtering CI Variables
By default, Turborepo filters environment variables to only those in `env`/`globalEnv`. CI variables may be missing:
```json
// If CI scripts need GITHUB_TOKEN but it's not in env:
{
"globalPassThroughEnv": ["GITHUB_TOKEN", "CI"],
"tasks": { ... }
}
```
Or use `--env-mode=loose` (not recommended for production).
### Shared Code in Apps (Should Be a Package)
```
// WRONG: Shared code inside an app
apps/
web/
shared/ # This breaks monorepo principles!
utils.ts
// CORRECT: Extract to a package
packages/
utils/
src/utils.ts
```
### Accessing Files Across Package Boundaries
```typescript
// WRONG: Reaching into another package's internals
import { Button } from "../../packages/ui/src/button";
// CORRECT: Install and import properly
import { Button } from "@repo/ui/button";
```
### Too Many Root Dependencies
```json
// WRONG: App dependencies in root
{
"dependencies": {
"react": "^18",
"next": "^14"
}
}
// CORRECT: Only repo tools in root
{
"devDependencies": {
"turbo": "latest"
}
}
```
## Common Task Configurations
### Standard Build Pipeline
```json
{
"$schema": "https://turborepo.dev/schema.v2.json",
"tasks": {
"build": {
"dependsOn": ["^build"],
"outputs": ["dist/**", ".next/**", "!.next/cache/**"]
},
"dev": {
"cache": false,
"persistent": true
}
}
}
```
Add a `transit` task if you have tasks that need parallel execution with cache invalidation (see below).
### Dev Task with `^dev` Pattern (for `turbo watch`)
A `dev` task with `dependsOn: ["^dev"]` and `persistent: false` in root turbo.json may look unusual but is **correct for `turbo watch` workflows**:
```json
// Root turbo.json
{
"tasks": {
"dev": {
"dependsOn": ["^dev"],
"cache": false,
"persistent": false // Packages have one-shot dev scripts
}
}
}
// Package turbo.json (apps/web/turbo.json)
{
"extends": ["//"],
"tasks": {
"dev": {
"persistent": true // Apps run long-running dev servers
}
}
}
```
**Why this works:**
- **Packages** (e.g., `@acme/db`, `@acme/validators`) have `"dev": "tsc"` — one-shot type generation that completes quickly
- **Apps** override with `persistent: true` for actual dev servers (Next.js, etc.)
- **`turbo watch`** re-runs the one-shot package `dev` scripts when source files change, keeping types in sync
**Intended usage:** Run `turbo watch dev` (not `turbo run dev`). Watch mode re-executes one-shot tasks on file changes while keeping persistent tasks running.
**Alternative pattern:** Use a separate task name like `prepare` or `generate` for one-shot dependency builds to make the intent clearer:
```json
{
"tasks": {
"prepare": {
"dependsOn": ["^prepare"],
"outputs": ["dist/**"]
},
"dev": {
"dependsOn": ["prepare"],
"cache": false,
"persistent": true
}
}
}
```
### Transit Nodes for Parallel Tasks with Cache Invalidation
Some tasks can run in parallel (don't need built output from dependencies) but must invalidate cache when dependency source code changes.
**The problem with `dependsOn: ["^taskname"]`:**
- Forces sequential execution (slow)
**The problem with `dependsOn: []` (no dependencies):**
- Allows parallel execution (fast)
- But cache is INCORRECT - changing dependency source won't invalidate cache
**Transit Nodes solve both:**
```json
{
"tasks": {
"transit": { "dependsOn": ["^transit"] },
"my-task": { "dependsOn": ["transit"] }
}
}
```
The `transit` task creates dependency relationships without matching any actual script, so tasks run in parallel with correct cache invalidation.
**How to identify tasks that need this pattern:** Look for tasks that read source files from dependencies but don't need their build outputs.
### With Environment Variables
```json
{
"globalEnv": ["NODE_ENV"],
"globalDependencies": [".env"],
"tasks": {
"build": {
"dependsOn": ["^build"],
"outputs": ["dist/**"],
"env": ["API_URL", "DATABASE_URL"]
}
}
}
```

description: Load Turborepo skill for creating workflows, tasks, and pipelines in monorepos. Use when users ask to "create a workflow", "make a task", "generate a pipeline", or set up build orchestration.
---
Load the Turborepo skill and help with monorepo task orchestration: creating workflows, configuring tasks, setting up pipelines, and optimizing builds.
## Workflow
### Step 1: Load turborepo skill
```
skill({ name: 'turborepo' })
```
### Step 2: Identify task type from user request
Analyze $ARGUMENTS to determine:
- **Topic**: configuration, caching, filtering, environment, CI, or CLI
- **Task type**: new setup, debugging, optimization, or implementation
Use decision trees in SKILL.md to select the relevant reference files.
### Step 3: Read relevant reference files
Based on task type, read from `references/<topic>/`:
| Task | Files to Read |
| -------------------- | --------------------------------------------------------- |
| Configure turbo.json | `configuration/README.md` + `configuration/tasks.md` |
| Debug cache issues | `caching/gotchas.md` |
| Set up remote cache | `caching/remote-cache.md` |
| Filter packages | `filtering/README.md` + `filtering/patterns.md` |
| Environment problems | `environment/gotchas.md` + `environment/modes.md` |
| Set up CI | `ci/README.md` + `ci/github-actions.md` or `ci/vercel.md` |
| CLI usage | `cli/commands.md` |
### Step 4: Execute task
Apply Turborepo-specific patterns from references to complete the user's request.
**CRITICAL - When creating tasks/scripts/pipelines:**
1. **DO NOT create Root Tasks** - Always create package tasks
2. Add scripts to each relevant package's `package.json` (e.g., `apps/web/package.json`, `packages/ui/package.json`)
3. Register the task in root `turbo.json`
4. Root `package.json` only contains `turbo run <task>` - never actual task logic
**Other things to verify:**
- `outputs` defined for cacheable tasks
- `dependsOn` uses correct syntax (`^task` vs `task`)
- Environment variables in `env` key
- `.env` files in `inputs` if used
- Use `turbo run` (not `turbo`) in package.json and CI
### Step 5: Summarize

# Dependency Management
Best practices for managing dependencies in a Turborepo monorepo.
## Core Principle: Install Where Used
Dependencies belong in the package that uses them, not the root.
```bash
# Good: Install in specific package
pnpm add react --filter=@repo/ui
pnpm add next --filter=web
# Avoid: Installing in root
pnpm add react -w # Only for repo-level tools!
```
## Benefits of Local Installation
### 1. Clarity
Each package's `package.json` lists exactly what it needs:
```json
// packages/ui/package.json
{
"dependencies": {
"react": "^18.0.0",
"class-variance-authority": "^0.7.0"
}
}
```
### 2. Flexibility
Different packages can use different versions when needed:
```json
// packages/legacy-ui/package.json
{ "dependencies": { "react": "^17.0.0" } }
// packages/ui/package.json
{ "dependencies": { "react": "^18.0.0" } }
```
### 3. Better Caching
Installing in root changes workspace lockfile, invalidating all caches.
### 4. Pruning Support
`turbo prune` can remove unused dependencies for Docker images.
## What Belongs in Root
Only repository-level tools:
```json
// Root package.json
{
"devDependencies": {
"turbo": "latest",
"husky": "^8.0.0",
"lint-staged": "^15.0.0"
}
}
```
**NOT** application dependencies:
- react, next, express
- lodash, axios, zod
- Testing libraries (unless truly repo-wide)
## Installing Dependencies
### Single Package
```bash
# pnpm
pnpm add lodash --filter=@repo/utils
# npm
npm install lodash --workspace=@repo/utils
# yarn
yarn workspace @repo/utils add lodash
# bun
cd packages/utils && bun add lodash
```
### Multiple Packages
```bash
# pnpm
pnpm add jest --save-dev --filter=web --filter=@repo/ui
# npm
npm install jest --save-dev --workspace=web --workspace=@repo/ui
# yarn (v2+)
yarn workspaces foreach -R --from '{web,@repo/ui}' add jest --dev
```
### Internal Packages
```bash
# pnpm
pnpm add @repo/ui --filter=web
# This updates package.json:
{
"dependencies": {
"@repo/ui": "workspace:*"
}
}
```
## Keeping Versions in Sync
### Option 1: Tooling
```bash
# syncpack - Check and fix version mismatches
npx syncpack list-mismatches
npx syncpack fix-mismatches
# manypkg - Similar functionality
npx @manypkg/cli check
npx @manypkg/cli fix
# sherif - Rust-based, very fast
npx sherif
```
### Option 2: Package Manager Commands
```bash
# pnpm - Update everywhere
pnpm up --recursive typescript@latest
# npm - Update in all workspaces
npm install typescript@latest --workspaces
```
### Option 3: pnpm Catalogs (pnpm 9.5+)
```yaml
# pnpm-workspace.yaml
packages:
- "apps/*"
- "packages/*"
catalog:
react: ^18.2.0
typescript: ^5.3.0
```
```json
// Any package.json
{
"dependencies": {
"react": "catalog:" // Uses version from catalog
}
}
```
## Internal vs External Dependencies
### Internal (Workspace)
```json
// pnpm/bun
{ "@repo/ui": "workspace:*" }
// npm/yarn
{ "@repo/ui": "*" }
```
Turborepo understands these relationships and orders builds accordingly.
### External (npm Registry)
```json
{ "lodash": "^4.17.21" }
```
Standard semver versioning from npm.
## Peer Dependencies
For library packages that expect the consumer to provide dependencies:
```json
// packages/ui/package.json
{
"peerDependencies": {
"react": "^18.0.0",
"react-dom": "^18.0.0"
},
"devDependencies": {
"react": "^18.0.0", // For development/testing
"react-dom": "^18.0.0"
}
}
```
## Common Issues
### "Module not found"
1. Check the dependency is installed in the right package
2. Run `pnpm install` / `npm install` to update lockfile
3. Check exports are defined in the package
### Version Conflicts
Packages can use different versions - this is a feature, not a bug. But if you need consistency:
1. Use tooling (syncpack, manypkg)
2. Use pnpm catalogs
3. Create a lint rule
### Hoisting Issues
Some tools expect dependencies in specific locations. Use package manager config:
```yaml
# .npmrc (pnpm)
public-hoist-pattern[]=*eslint*
public-hoist-pattern[]=*prettier*
```
## Lockfile
**Required** for:
- Reproducible builds
- Turborepo dependency analysis
- Cache correctness
```bash
# Commit your lockfile!
git add pnpm-lock.yaml # or package-lock.json, yarn.lock
```

# Creating Internal Packages
How to create and structure internal packages in your monorepo.
## Package Creation Checklist
1. Create directory in `packages/`
2. Add `package.json` with name and exports
3. Add source code in `src/`
4. Add `tsconfig.json` if using TypeScript
5. Install as dependency in consuming packages
6. Run package manager install to update lockfile
## Package Compilation Strategies
### Just-in-Time (JIT)
Export TypeScript directly. The consuming app's bundler compiles it.
```json
// packages/ui/package.json
{
"name": "@repo/ui",
"exports": {
"./button": "./src/button.tsx",
"./card": "./src/card.tsx"
},
"scripts": {
"lint": "eslint .",
"check-types": "tsc --noEmit"
}
}
```
**When to use:**
- Apps use modern bundlers (Turbopack, webpack, Vite)
- You want minimal configuration
- Build times are acceptable without caching
**Limitations:**
- No Turborepo cache for the package itself
- Consumer must support TypeScript compilation
- Can't use TypeScript `paths` (use Node.js subpath imports instead)
### Compiled
Package handles its own compilation.
```json
// packages/ui/package.json
{
"name": "@repo/ui",
"exports": {
"./button": {
"types": "./src/button.tsx",
"default": "./dist/button.js"
}
},
"scripts": {
"build": "tsc",
"dev": "tsc --watch"
}
}
```
```json
// packages/ui/tsconfig.json
{
"extends": "@repo/typescript-config/library.json",
"compilerOptions": {
"outDir": "dist",
"rootDir": "src"
},
"include": ["src"],
"exclude": ["node_modules", "dist"]
}
```
**When to use:**
- You want Turborepo to cache builds
- Package will be used by non-bundler tools
- You need maximum compatibility
**Remember:** Add `dist/**` to turbo.json outputs!
## Defining Exports
### Multiple Entrypoints
```json
{
"exports": {
".": "./src/index.ts", // @repo/ui
"./button": "./src/button.tsx", // @repo/ui/button
"./card": "./src/card.tsx", // @repo/ui/card
"./hooks": "./src/hooks/index.ts" // @repo/ui/hooks
}
}
```
### Conditional Exports (Compiled)
```json
{
"exports": {
"./button": {
"types": "./src/button.tsx",
"import": "./dist/button.mjs",
"require": "./dist/button.cjs",
"default": "./dist/button.js"
}
}
}
```
## Installing Internal Packages
### Add to Consuming Package
```json
// apps/web/package.json
{
"dependencies": {
"@repo/ui": "workspace:*" // pnpm/bun
// "@repo/ui": "*" // npm/yarn
}
}
```
### Run Install
```bash
pnpm install # Updates lockfile with new dependency
```
### Import and Use
```typescript
// apps/web/src/page.tsx
import { Button } from '@repo/ui/button';
export default function Page() {
return <Button>Click me</Button>;
}
```
## One Purpose Per Package
### Good Examples
```
packages/
├── ui/ # Shared UI components
├── utils/ # General utilities
├── auth/ # Authentication logic
├── database/ # Database client/schemas
├── eslint-config/ # ESLint configuration
├── typescript-config/ # TypeScript configuration
└── api-client/ # Generated API client
```
### Avoid Mega-Packages
```
// BAD: One package for everything
packages/
└── shared/
├── components/
├── utils/
├── hooks/
├── types/
└── api/
// GOOD: Separate by purpose
packages/
├── ui/ # Components
├── utils/ # Utilities
├── hooks/ # React hooks
├── types/ # Shared TypeScript types
└── api-client/ # API utilities
```
## Config Packages
### TypeScript Config
```json
// packages/typescript-config/package.json
{
"name": "@repo/typescript-config",
"exports": {
"./base.json": "./base.json",
"./nextjs.json": "./nextjs.json",
"./library.json": "./library.json"
}
}
```
### ESLint Config
```json
// packages/eslint-config/package.json
{
"name": "@repo/eslint-config",
"exports": {
"./base": "./base.js",
"./next": "./next.js"
},
"dependencies": {
"eslint": "^8.0.0",
"eslint-config-next": "latest"
}
}
```
## Common Mistakes
### Forgetting to Export
```json
// BAD: No exports defined
{
"name": "@repo/ui"
}
// GOOD: Clear exports
{
"name": "@repo/ui",
"exports": {
"./button": "./src/button.tsx"
}
}
```
### Wrong Workspace Syntax
```json
// pnpm/bun
{ "@repo/ui": "workspace:*" } // Correct
// npm/yarn
{ "@repo/ui": "*" } // Correct
{ "@repo/ui": "workspace:*" } // Wrong for npm/yarn!
```
### Missing from turbo.json Outputs
```json
// Package builds to dist/, but turbo.json doesn't know
{
"tasks": {
"build": {
"outputs": [".next/**"] // Missing dist/**!
}
}
}
// Correct
{
"tasks": {
"build": {
"outputs": [".next/**", "dist/**"]
}
}
}
```
## TypeScript Best Practices
### Use Node.js Subpath Imports (Not `paths`)
TypeScript `compilerOptions.paths` breaks with JIT packages. Use Node.js subpath imports instead (TypeScript 5.4+).
**JIT Package:**
```json
// packages/ui/package.json
{
"imports": {
"#*": "./src/*"
}
}
```
```typescript
// packages/ui/button.tsx
import { MY_STRING } from "#utils.ts"; // Uses .ts extension
```
**Compiled Package:**
```json
// packages/ui/package.json
{
"imports": {
"#*": "./dist/*"
}
}
```
```typescript
// packages/ui/button.tsx
import { MY_STRING } from "#utils.js"; // Uses .js extension
```
### Use `tsc` for Internal Packages
For internal packages, prefer `tsc` over bundlers. Bundlers can mangle code before it reaches your app's bundler, causing hard-to-debug issues.
### Enable Go-to-Definition
For Compiled Packages, enable declaration maps:
```json
// tsconfig.json
{
"compilerOptions": {
"declaration": true,
"declarationMap": true
}
}
```
This creates `.d.ts` and `.d.ts.map` files for IDE navigation.
### No Root tsconfig.json Needed
Each package should have its own `tsconfig.json`. A root one causes all tasks to miss cache when changed. Only use root `tsconfig.json` for non-package scripts.
### Avoid TypeScript Project References
They add complexity and another caching layer. Turborepo handles dependencies better.

# Repository Structure
Detailed guidance on structuring a Turborepo monorepo.
## Workspace Configuration
### pnpm (Recommended)
```yaml
# pnpm-workspace.yaml
packages:
- "apps/*"
- "packages/*"
```
### npm/yarn/bun
```json
// package.json
{
"workspaces": ["apps/*", "packages/*"]
}
```
## Root package.json
```json
{
"name": "my-monorepo",
"private": true,
"packageManager": "pnpm@9.0.0",
"scripts": {
"build": "turbo run build",
"dev": "turbo run dev",
"lint": "turbo run lint",
"test": "turbo run test"
},
"devDependencies": {
"turbo": "latest"
}
}
```
Key points:
- `private: true` - Prevents accidental publishing
- `packageManager` - Enforces consistent package manager version
- **Scripts only delegate to `turbo run`** - No actual build logic here!
- Minimal devDependencies (just turbo and repo tools)
## Always Prefer Package Tasks
**Always use package tasks. Only use Root Tasks if you cannot succeed with package tasks.**
```json
// packages/web/package.json
{
"scripts": {
"build": "next build",
"lint": "eslint .",
"test": "vitest",
"typecheck": "tsc --noEmit"
}
}
// packages/api/package.json
{
"scripts": {
"build": "tsc",
"lint": "eslint .",
"test": "vitest",
"typecheck": "tsc --noEmit"
}
}
```
Package tasks enable Turborepo to:
1. **Parallelize** - Run `web#lint` and `api#lint` simultaneously
2. **Cache individually** - Each package's task output is cached separately
3. **Filter precisely** - Run `turbo run test --filter=web` for just one package
**Root Tasks are a fallback** for tasks that truly cannot run per-package:
```json
// AVOID unless necessary - sequential, not parallelized, can't filter
{
"scripts": {
"lint": "eslint apps/web && eslint apps/api && eslint packages/ui"
}
}
```
## Root turbo.json
```json
{
"$schema": "https://turborepo.dev/schema.v2.json",
"tasks": {
"build": {
"dependsOn": ["^build"],
"outputs": ["dist/**", ".next/**", "!.next/cache/**"]
},
"lint": {},
"test": {
"dependsOn": ["build"]
},
"dev": {
"cache": false,
"persistent": true
}
}
}
```
## Directory Organization
### Grouping Packages
You can group packages by adding more workspace paths:
```yaml
# pnpm-workspace.yaml
packages:
- "apps/*"
- "packages/*"
- "packages/config/*" # Grouped configs
- "packages/features/*" # Feature packages
```
This allows:
```
packages/
├── ui/
├── utils/
├── config/
│ ├── eslint/
│ ├── typescript/
│ └── tailwind/
└── features/
├── auth/
└── payments/
```
### What NOT to Do
```yaml
# BAD: Nested wildcards cause ambiguous behavior
packages:
- "packages/**" # Don't do this!
```
## Package Anatomy
### Minimum Required Files
```
packages/ui/
├── package.json # Required: Makes it a package
├── src/ # Source code
│ └── button.tsx
└── tsconfig.json # TypeScript config (if using TS)
```
### package.json Requirements
```json
{
"name": "@repo/ui", // Unique, namespaced name
"version": "0.0.0", // Version (can be 0.0.0 for internal)
"private": true, // Prevents accidental publishing
"exports": { // Entry points
"./button": "./src/button.tsx"
}
}
```
## TypeScript Configuration
### Shared Base Config
Create a shared TypeScript config package:
```
packages/
└── typescript-config/
├── package.json
├── base.json
├── nextjs.json
└── library.json
```
```json
// packages/typescript-config/base.json
{
"compilerOptions": {
"strict": true,
"esModuleInterop": true,
"skipLibCheck": true,
"moduleResolution": "bundler",
"module": "ESNext",
"target": "ES2022"
}
}
```
### Extending in Packages
```json
// packages/ui/tsconfig.json
{
"extends": "@repo/typescript-config/library.json",
"compilerOptions": {
"outDir": "dist",
"rootDir": "src"
},
"include": ["src"],
"exclude": ["node_modules", "dist"]
}
```
### No Root tsconfig.json
You likely don't need a `tsconfig.json` in the workspace root. Each package should have its own config extending from the shared config package.
## ESLint Configuration
### Shared Config Package
```
packages/
└── eslint-config/
├── package.json
├── base.js
├── next.js
└── library.js
```
```json
// packages/eslint-config/package.json
{
"name": "@repo/eslint-config",
"exports": {
"./base": "./base.js",
"./next": "./next.js",
"./library": "./library.js"
}
}
```
### Using in Packages
```js
// apps/web/.eslintrc.js
module.exports = {
extends: ["@repo/eslint-config/next"],
};
```
## Lockfile
A lockfile is **required** for:
- Reproducible builds
- Turborepo to understand package dependencies
- Cache correctness
Without a lockfile, you'll see unpredictable behavior.

# Debugging Cache Issues
## Diagnostic Tools
### `--summarize`
Generates a JSON file with all hash inputs. Compare two runs to find differences.
```bash
turbo build --summarize
# Creates .turbo/runs/<run-id>.json
```
The summary includes:
- Global hash and its inputs
- Per-task hashes and their inputs
- Environment variables that affected the hash
**Comparing runs:**
```bash
# Run twice, compare the summaries
diff .turbo/runs/<first-run>.json .turbo/runs/<second-run>.json
```
### `--dry` / `--dry=json`
See what would run without executing anything:
```bash
turbo build --dry
turbo build --dry=json # machine-readable output
```
Shows cache status for each task without running them.
### `--force`
Skip reading cache, re-execute all tasks:
```bash
turbo build --force
```
Useful to verify tasks actually work (not just cached results).
## Unexpected Cache Misses
**Symptom:** Task runs when you expected a cache hit.
### Environment Variable Changed
Check if an env var in the `env` key changed:
```json
{
"tasks": {
"build": {
"env": ["API_URL", "NODE_ENV"]
}
}
}
```
Different `API_URL` between runs = cache miss.
### .env File Changed
`.env` files aren't tracked by default. Add to `inputs`:
```json
{
"tasks": {
"build": {
"inputs": ["$TURBO_DEFAULT$", ".env", ".env.local"]
}
}
}
```
Or use `globalDependencies` for repo-wide env files:
```json
{
"globalDependencies": [".env"]
}
```
### Lockfile Changed
Installing/updating packages changes the global hash.
### Source Files Changed
Any file in the package (or in `inputs`) triggers a miss.
### turbo.json Changed
Config changes invalidate the global hash.
## Incorrect Cache Hits
**Symptom:** Cached output is stale/wrong.
### Missing Environment Variable
Task uses an env var not listed in `env`:
```javascript
// build.js
const apiUrl = process.env.API_URL; // not tracked!
```
Fix: add to task config:
```json
{
"tasks": {
"build": {
"env": ["API_URL"]
}
}
}
```
### Missing File in Inputs
Task reads a file outside default inputs:
```json
{
"tasks": {
"build": {
"inputs": [
"$TURBO_DEFAULT$",
"../../shared-config.json" // file outside package
]
}
}
}
```
## Useful Flags
```bash
# Only show output for cache misses
turbo build --output-logs=new-only
# Show output for everything (debugging)
turbo build --output-logs=full
# See why tasks are running
turbo build --verbosity=2
```
## Quick Checklist
Cache miss when expected hit:
1. Run with `--summarize`, compare with previous run
2. Check env vars with `--dry=json`
3. Look for lockfile/config changes in git
Cache hit when expected miss:
1. Verify env var is in `env` array
2. Verify file is in `inputs` array
3. Check if file is outside package directory

# Remote Caching
Share cache artifacts across your team and CI pipelines.
## Benefits
- Team members get cache hits from each other's work
- CI gets cache hits from local development (and vice versa)
- Dramatically faster CI runs after first build
- No more "works on my machine" rebuilds
## Vercel Remote Cache
Free, zero-config when deploying on Vercel. For local dev and other CI:
### Local Development Setup
```bash
# Authenticate with Vercel
npx turbo login
# Link repo to your Vercel team
npx turbo link
```
This creates `.turbo/config.json` with your team info (gitignored by default).
### CI Setup
Set these environment variables:
```bash
TURBO_TOKEN=<your-token>
TURBO_TEAM=<your-team-slug>
```
Get your token from Vercel dashboard → Settings → Tokens.
**GitHub Actions example:**
```yaml
- name: Build
run: npx turbo build
env:
TURBO_TOKEN: ${{ secrets.TURBO_TOKEN }}
TURBO_TEAM: ${{ vars.TURBO_TEAM }}
```
## Configuration in turbo.json
```json
{
"remoteCache": {
"enabled": true,
"signature": false
}
}
```
Options:
- `enabled`: toggle remote cache (default: true when authenticated)
- `signature`: require artifact signing (default: false)
## Artifact Signing
Verify cache artifacts haven't been tampered with:
```bash
# Set a secret key (use same key across all environments)
export TURBO_REMOTE_CACHE_SIGNATURE_KEY="your-secret-key"
```
Enable in config:
```json
{
"remoteCache": {
"signature": true
}
}
```
Signed artifacts can only be restored if the signature matches.
## Self-Hosted Options
Community implementations for running your own cache server:
- **turbo-remote-cache** (Node.js) - supports S3, GCS, Azure
- **turborepo-remote-cache** (Go) - lightweight, S3-compatible
- **ducktape** (Rust) - high-performance option
Configure with environment variables:
```bash
TURBO_API=https://your-cache-server.com
TURBO_TOKEN=your-auth-token
TURBO_TEAM=your-team
```
## Cache Behavior Control
```bash
# Disable remote cache for a run
turbo build --remote-cache-read-only # read but don't write
turbo build --no-cache # skip cache entirely
# Environment variable alternative
TURBO_REMOTE_ONLY=true # only use remote, skip local
```
## Debugging Remote Cache
```bash
# Verbose output shows cache operations
turbo build --verbosity=2
# Check if remote cache is configured
turbo config
```
Look for:
- "Remote caching enabled" in output
- Upload/download messages during runs
- "cache hit, replaying output" with remote cache indicator

# GitHub Actions
Complete setup guide for Turborepo with GitHub Actions.
## Basic Workflow Structure
```yaml
name: CI
on:
push:
branches: [main]
pull_request:
branches: [main]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
with:
fetch-depth: 2
- uses: actions/setup-node@v4
with:
node-version: 20
- name: Install dependencies
run: npm ci
- name: Build and Test
run: turbo run build test lint
```
## Package Manager Setup
### pnpm
```yaml
- uses: pnpm/action-setup@v3
with:
version: 9
- uses: actions/setup-node@v4
with:
node-version: 20
cache: 'pnpm'
- run: pnpm install --frozen-lockfile
```
### Yarn
```yaml
- uses: actions/setup-node@v4
with:
node-version: 20
cache: 'yarn'
- run: yarn install --frozen-lockfile
```
### Bun
```yaml
- uses: oven-sh/setup-bun@v1
with:
bun-version: latest
- run: bun install --frozen-lockfile
```
## Remote Cache Setup
### 1. Create Vercel Access Token
1. Go to [Vercel Dashboard](https://vercel.com/account/tokens)
2. Create a new token with appropriate scope
3. Copy the token value
### 2. Add Secrets and Variables
In your GitHub repository settings:
**Secrets** (Settings > Secrets and variables > Actions > Secrets):
- `TURBO_TOKEN`: Your Vercel access token
**Variables** (Settings > Secrets and variables > Actions > Variables):
- `TURBO_TEAM`: Your Vercel team slug
### 3. Add to Workflow
```yaml
jobs:
build:
runs-on: ubuntu-latest
env:
TURBO_TOKEN: ${{ secrets.TURBO_TOKEN }}
TURBO_TEAM: ${{ vars.TURBO_TEAM }}
```
## Alternative: actions/cache
If you can't use remote cache, cache Turborepo's local cache directory:
```yaml
- uses: actions/cache@v4
with:
path: .turbo
key: turbo-${{ runner.os }}-${{ hashFiles('**/turbo.json', '**/package-lock.json') }}
restore-keys: |
turbo-${{ runner.os }}-
```
Note: This is less effective than remote cache since it's per-branch.
## Complete Example
```yaml
name: CI
on:
push:
branches: [main]
pull_request:
branches: [main]
jobs:
build:
runs-on: ubuntu-latest
env:
TURBO_TOKEN: ${{ secrets.TURBO_TOKEN }}
TURBO_TEAM: ${{ vars.TURBO_TEAM }}
steps:
- uses: actions/checkout@v4
with:

- name: Install dependencies
run: pnpm install --frozen-lockfile
- name: Build
run: turbo run build --affected
- name: Test

# CI Optimization Patterns
Strategies for efficient CI/CD with Turborepo.
## PR vs Main Branch Builds
### PR Builds: Only Affected
Test only what changed in the PR:
```yaml
- name: Test (PR)
if: github.event_name == 'pull_request'
run: turbo run build test --affected
```
### Main Branch: Full Build
Ensure complete validation on merge:
```yaml
- name: Test (Main)
if: github.ref == 'refs/heads/main'
run: turbo run build test
```
## Custom Git Ranges with --filter
For advanced scenarios, use `--filter` with git refs:
```bash
# Changes since specific commit
turbo run test --filter="...[abc123]"
# Changes between refs
turbo run test --filter="...[main...HEAD]"
# Changes in last 3 commits
turbo run test --filter="...[HEAD~3]"
```
## Caching Strategies
### Remote Cache (Recommended)
Best performance - shared across all CI runs and developers:
```yaml
env:
TURBO_TOKEN: ${{ secrets.TURBO_TOKEN }}
TURBO_TEAM: ${{ vars.TURBO_TEAM }}
```
### actions/cache Fallback
When remote cache isn't available:
```yaml
- uses: actions/cache@v4
with:
path: .turbo
key: turbo-${{ runner.os }}-${{ github.sha }}
restore-keys: |
turbo-${{ runner.os }}-${{ github.ref }}-
turbo-${{ runner.os }}-
```
Limitations:
- Cache is branch-scoped
- PRs restore from base branch cache
- Less efficient than remote cache
## Matrix Builds
Test across Node versions:
```yaml
strategy:
matrix:
node: [18, 20, 22]
steps:
- uses: actions/setup-node@v4
with:
node-version: ${{ matrix.node }}
- run: turbo run test
```
## Parallelizing Across Jobs
Split tasks into separate jobs:
```yaml
jobs:
lint:
runs-on: ubuntu-latest
steps:
- run: turbo run lint --affected
test:
runs-on: ubuntu-latest
steps:
- run: turbo run test --affected
build:
runs-on: ubuntu-latest
needs: [lint, test]
steps:
- run: turbo run build
```
### Cache Considerations
When parallelizing:
- Each job has separate cache writes
- Remote cache handles this automatically
- With actions/cache, use unique keys per job to avoid conflicts
```yaml
- uses: actions/cache@v4
with:
path: .turbo
key: turbo-${{ runner.os }}-${{ github.job }}-${{ github.sha }}
```
## Conditional Tasks
Skip expensive tasks on draft PRs:
```yaml
- name: E2E Tests
if: github.event.pull_request.draft == false
run: turbo run test:e2e --affected
```
Or require label for full test:
```yaml
- name: Full Test Suite
if: contains(github.event.pull_request.labels.*.name, 'full-test')
run: turbo run test
```

# Vercel Deployment
Turborepo integrates seamlessly with Vercel for monorepo deployments.
## Remote Cache
Remote caching is **automatically enabled** when deploying to Vercel. No configuration needed - Vercel detects Turborepo and enables caching.
This means:
- No `TURBO_TOKEN` or `TURBO_TEAM` setup required on Vercel
- Cache is shared across all deployments
- Preview and production builds benefit from cache
## turbo-ignore
Skip unnecessary builds when a package hasn't changed using `turbo-ignore`.
### Installation
```bash
npx turbo-ignore
```
Or install globally in your project:
```bash
pnpm add -D turbo-ignore
```
### Setup in Vercel
1. Go to your project in Vercel Dashboard
2. Navigate to Settings > Git > Ignored Build Step
3. Select "Custom" and enter:
```bash
npx turbo-ignore
```
### How It Works
`turbo-ignore` checks if the current package (or its dependencies) changed since the last successful deployment:
1. Compares current commit to last deployed commit
2. Uses Turborepo's dependency graph
3. Returns exit code 0 (skip) if no changes
4. Returns exit code 1 (build) if changes detected
### Options
```bash
# Check specific package
npx turbo-ignore web
# Use specific comparison ref
npx turbo-ignore --fallback=HEAD~1
# Verbose output
npx turbo-ignore --verbose
```
## Environment Variables
Set environment variables in Vercel Dashboard:
1. Go to Project Settings > Environment Variables
2. Add variables for each environment (Production, Preview, Development)
Common variables:
- `DATABASE_URL`
- `API_KEY`
- Package-specific config
## Monorepo Root Directory
For monorepos, set the root directory in Vercel:
1. Project Settings > General > Root Directory
2. Set to the package path (e.g., `apps/web`)
Vercel automatically:
- Installs dependencies from monorepo root
- Runs build from the package directory
- Detects framework settings
## Build Command
Vercel auto-detects `turbo run build` when `turbo.json` exists at root.
Override if needed:
```bash
turbo run build --filter=web
```
Or for production-only optimizations:
```bash
turbo run build --filter=web --env-mode=strict
```

# turbo run Flags Reference
Full docs: https://turborepo.dev/docs/reference/run
## Package Selection
### `--filter` / `-F`
Select specific packages to run tasks in.
```bash
turbo build --filter=web
turbo build -F=@repo/ui -F=@repo/utils
turbo test --filter=./apps/*
```
See `filtering/` for complete syntax (globs, dependencies, git ranges).
### Task Identifier Syntax (v2.2.4+)
Run specific package tasks directly:
```bash
turbo run web#build # Build web package
turbo run web#build docs#lint # Multiple specific tasks
```
### `--affected`
Run only in packages changed since the base branch.
```bash
turbo build --affected
turbo test --affected --filter=./apps/* # combine with filter
```
**How it works:**
- Default: compares `main...HEAD`
- In GitHub Actions: auto-detects `GITHUB_BASE_REF`
- Override base: `TURBO_SCM_BASE=development turbo build --affected`
- Override head: `TURBO_SCM_HEAD=your-branch turbo build --affected`
**Requires git history** - shallow clones may fall back to running all tasks.
## Execution Control
### `--dry` / `--dry=json`
Preview what would run without executing.
```bash
turbo build --dry # human-readable
turbo build --dry=json # machine-readable
```
### `--force`
Ignore all cached artifacts, re-run everything.
```bash
turbo build --force
```
### `--concurrency`
Limit parallel task execution.
```bash
turbo build --concurrency=4 # max 4 tasks
turbo build --concurrency=50% # 50% of CPU cores
```
### `--continue`
Keep running other tasks when one fails.
```bash
turbo build test --continue
```
### `--only`
Run only the specified task, skip its dependencies.
```bash
turbo build --only # skip running dependsOn tasks
```
### `--parallel` (Discouraged)
Ignores task graph dependencies, runs all tasks simultaneously. **Avoid using this flag**—if tasks need to run in parallel, configure `dependsOn` correctly instead. Using `--parallel` bypasses Turborepo's dependency graph, which can cause race conditions and incorrect builds.
## Cache Control
### `--cache`
Fine-grained cache behavior control.
```bash
# Default: read/write both local and remote
turbo build --cache=local:rw,remote:rw
# Read-only local, no remote
turbo build --cache=local:r,remote:
# Disable local, read-only remote
turbo build --cache=local:,remote:r
# Disable all caching
turbo build --cache=local:,remote:
```
## Output & Debugging
### `--graph`
Generate task graph visualization.
```bash
turbo build --graph # opens in browser
turbo build --graph=graph.svg # SVG file
turbo build --graph=graph.png # PNG file
turbo build --graph=graph.json # JSON data
turbo build --graph=graph.mermaid # Mermaid diagram
```
### `--summarize`
Generate JSON run summary for debugging.
```bash
turbo build --summarize
# creates .turbo/runs/<run-id>.json
```
### `--output-logs`
Control log output verbosity.
```bash
turbo build --output-logs=full # all logs (default)
turbo build --output-logs=new-only # only cache misses
turbo build --output-logs=errors-only # only failures
turbo build --output-logs=none # silent
```
### `--profile`
Generate Chrome tracing profile for performance analysis.
```bash
turbo build --profile=profile.json
# open chrome://tracing and load the file
```
### `--verbosity` / `-v`
Control turbo's own log level.
```bash
turbo build -v # verbose
turbo build -vv # more verbose
turbo build -vvv # maximum verbosity
```
## Environment
### `--env-mode`
Control environment variable handling.
```bash
turbo build --env-mode=strict # only declared env vars (default)
turbo build --env-mode=loose # include all env vars in hash
```
## UI
### `--ui`
Select output interface.
```bash
turbo build --ui=tui # interactive terminal UI (default in TTY)
turbo build --ui=stream # streaming logs (default in CI)
```
---
# turbo-ignore
Full docs: https://turborepo.dev/docs/reference/turbo-ignore
Skip CI work when nothing relevant changed. Useful for skipping container setup.
## Basic Usage
```bash

# Global Options Reference
Options that affect all tasks. Full docs: https://turborepo.dev/docs/reference/configuration
## globalEnv
Environment variables affecting all task hashes.
```json
{
"globalEnv": ["CI", "NODE_ENV", "VERCEL_*"]
}
```
Use for variables that should invalidate all caches when changed.
## globalDependencies
Files that affect all task hashes.
```json
{
"globalDependencies": [
"tsconfig.json",
".env",
"pnpm-lock.yaml"
]
}
```
Lockfile is included by default. Add shared configs here.
## globalPassThroughEnv
Variables available to tasks but not included in hash.
```json
{
"globalPassThroughEnv": ["AWS_SECRET_KEY", "GITHUB_TOKEN"]
}
```
Use for credentials that shouldn't affect cache keys.
## cacheDir
Custom cache location. Default: `node_modules/.cache/turbo`.
```json
{
"cacheDir": ".turbo/cache"
}
```
## daemon
Background process for faster subsequent runs. Default: `true`.
```json
{
"daemon": false
}
```
Disable in CI or when debugging.
## envMode
How unspecified env vars are handled. Default: `"strict"`.
```json
{
"envMode": "strict" // Only specified vars available
// or
"envMode": "loose" // All vars pass through
}
```
Strict mode catches missing env declarations.
## ui
Terminal UI mode. Default: `"stream"`.
```json
{
"ui": "tui" // Interactive terminal UI
// or
"ui": "stream" // Traditional streaming logs
}
```
TUI provides better UX for parallel tasks.
## remoteCache
Configure remote caching.
```json
{
"remoteCache": {
"enabled": true,
"signature": true,
"timeout": 30,
"uploadTimeout": 60
}
}
```
| Option | Default | Description |
| --------------- | ---------------------- | ------------------------------------------------------ |
| `enabled` | `true` | Enable/disable remote caching |
| `signature` | `false` | Sign artifacts with `TURBO_REMOTE_CACHE_SIGNATURE_KEY` |
| `preflight` | `false` | Send OPTIONS request before cache requests |
| `timeout` | `30` | Timeout in seconds for cache operations |
| `uploadTimeout` | `60` | Timeout in seconds for uploads |
| `apiUrl` | `"https://vercel.com"` | Remote cache API endpoint |
| `loginUrl` | `"https://vercel.com"` | Login endpoint |
| `teamId` | - | Team ID (must start with `team_`) |
| `teamSlug` | - | Team slug for querystring |
See https://turborepo.dev/docs/core-concepts/remote-caching for setup.
## concurrency
Default: `"10"`
Limit parallel task execution.
```json
{
"concurrency": "4" // Max 4 tasks at once
// or
"concurrency": "50%" // 50% of available CPUs
}
```
## futureFlags
Enable experimental features that will become default in future versions.
```json
{
"futureFlags": {
"errorsOnlyShowHash": true
}
}
```
### `errorsOnlyShowHash`
When using `outputLogs: "errors-only"`, show task hashes on start/completion:
- Cache miss: `cache miss, executing <hash> (only logging errors)`
- Cache hit: `cache hit, replaying logs (no errors) <hash>`
## noUpdateNotifier
Disable update notifications when new turbo versions are available.
```json
{
"noUpdateNotifier": true
}
```
## dangerouslyDisablePackageManagerCheck
Bypass the `packageManager` field requirement. Use for incremental migration.
```json
{
"dangerouslyDisablePackageManagerCheck": true
}
```
**Warning**: Unstable lockfiles can cause unpredictable behavior.
## Git Worktree Cache Sharing (Pre-release)
When working in Git worktrees, Turborepo automatically shares local cache between the main worktree and linked worktrees.
**How it works:**
- Detects worktree configuration
- Redirects cache to main worktree's `.turbo/cache`
- Works alongside Remote Cache
**Benefits:**
- Cache hits across branches
- Reduced disk usage
- Faster branch switching
**Disabled by**: Setting explicit `cacheDir` in turbo.json.

# Configuration Gotchas
Common mistakes and how to fix them.
## #1 Root Scripts Not Using `turbo run`
Root `package.json` scripts for turbo tasks MUST use `turbo run`, not direct commands.
```json
// WRONG - bypasses turbo, no parallelization or caching
{
"scripts": {
"build": "bun build",
"dev": "bun dev"
}
}
// CORRECT - delegates to turbo
{
"scripts": {
"build": "turbo run build",
"dev": "turbo run dev"
}
}
```
**Why this matters:** Running `bun build` or `npm run build` at root bypasses Turborepo entirely - no parallelization, no caching, no dependency graph awareness.
## #2 Using `&&` to Chain Turbo Tasks
Don't use `&&` to chain tasks that turbo should orchestrate.
```json
// WRONG - changeset:publish chains turbo task with non-turbo command
{
"scripts": {
"changeset:publish": "bun build && changeset publish"
}
}
// CORRECT - use turbo run, let turbo handle dependencies
{
"scripts": {
"changeset:publish": "turbo run build && changeset publish"
}
}
```
If the second command (`changeset publish`) depends on build outputs, the turbo task should run through turbo to get caching and parallelization benefits.
## #3 Overly Broad globalDependencies
`globalDependencies` affects hash for ALL tasks in ALL packages. Be specific.
```json
// WRONG - affects all hashes
{
"globalDependencies": ["**/.env.*local"]
}
// CORRECT - move to specific tasks that need it
{
"globalDependencies": [".env"],
"tasks": {
"build": {
"inputs": ["$TURBO_DEFAULT$", ".env*"],
"outputs": ["dist/**"]
}
}
}
```
**Why this matters:** `**/.env.*local` matches .env files in ALL packages, causing unnecessary cache invalidation. Instead:
- Use `globalDependencies` only for truly global files (root `.env`)
- Use task-level `inputs` for package-specific .env files with `$TURBO_DEFAULT$` to preserve default behavior
## #4 Repetitive Task Configuration
Look for repeated configuration across tasks that can be collapsed.
```json
// WRONG - repetitive env and inputs across tasks
{
"tasks": {
"build": {
"env": ["API_URL", "DATABASE_URL"],
"inputs": ["$TURBO_DEFAULT$", ".env*"]
},
"test": {
"env": ["API_URL", "DATABASE_URL"],
"inputs": ["$TURBO_DEFAULT$", ".env*"]
}
}
}
// BETTER - use globalEnv and globalDependencies
{
"globalEnv": ["API_URL", "DATABASE_URL"],
"globalDependencies": [".env*"],
"tasks": {
"build": {},
"test": {}
}
}
```
**When to use global vs task-level:**
- `globalEnv` / `globalDependencies` - affects ALL tasks, use for truly shared config
- Task-level `env` / `inputs` - use when only specific tasks need it
## #5 Using `../` to Traverse Out of Package in `inputs`
Don't use relative paths like `../` to reference files outside the package. Use `$TURBO_ROOT$` instead.
```json
// WRONG - traversing out of package
{
"tasks": {
"build": {
"inputs": ["$TURBO_DEFAULT$", "../shared-config.json"]
}
}
}
// CORRECT - use $TURBO_ROOT$ for repo root
{
"tasks": {
"build": {
"inputs": ["$TURBO_DEFAULT$", "$TURBO_ROOT$/shared-config.json"]
}
}
}
```
## #6 MOST COMMON MISTAKE: Creating Root Tasks
**DO NOT create Root Tasks. ALWAYS create package tasks.**
When you need to create a task (build, lint, test, typecheck, etc.):
1. Add the script to **each relevant package's** `package.json`
2. Register the task in root `turbo.json`
3. Root `package.json` only contains `turbo run <task>`
```json
// WRONG - DO NOT DO THIS
// Root package.json with task logic
{
"scripts": {
"build": "cd apps/web && next build && cd ../api && tsc",
"lint": "eslint apps/ packages/",
"test": "vitest"
}
}
// CORRECT - DO THIS
// apps/web/package.json
{ "scripts": { "build": "next build", "lint": "eslint .", "test": "vitest" } }
// apps/api/package.json
{ "scripts": { "build": "tsc", "lint": "eslint .", "test": "vitest" } }
// packages/ui/package.json
{ "scripts": { "build": "tsc", "lint": "eslint .", "test": "vitest" } }
// Root package.json - ONLY delegates
{ "scripts": { "build": "turbo run build", "lint": "turbo run lint", "test": "turbo run test" } }
// turbo.json - register tasks
{
"tasks": {
"build": { "dependsOn": ["^build"], "outputs": ["dist/**"] },
"lint": {},
"test": {}
}
}
```
**Why this matters:**
- Package tasks run in **parallel** across all packages
- Each package's output is cached **individually**
- You can **filter** to specific packages: `turbo run test --filter=web`
Root Tasks (`//#taskname`) defeat all these benefits. Only use them for tasks that truly cannot exist in any package (extremely rare).
## #7 Tasks That Need Parallel Execution + Cache Invalidation
Some tasks can run in parallel (don't need built output from dependencies) but must still invalidate cache when dependency source code changes. Using `dependsOn: ["^taskname"]` forces sequential execution. Using no dependencies breaks cache invalidation.
**Use Transit Nodes for these tasks:**
```json
// WRONG - forces sequential execution (SLOW)
"my-task": {
"dependsOn": ["^my-task"]
}
// ALSO WRONG - no dependency awareness (INCORRECT CACHING)
"my-task": {}
// CORRECT - use Transit Nodes for parallel + correct caching
{
"tasks": {
"transit": { "dependsOn": ["^transit"] },
"my-task": { "dependsOn": ["transit"] }
}
}
```
**Why Transit Nodes work:**
- `transit` creates dependency relationships without matching any actual script
- Tasks that depend on `transit` gain dependency awareness
- Since `transit` completes instantly (no script), tasks run in parallel
- Cache correctly invalidates when dependency source code changes
**How to identify tasks that need this pattern:** Look for tasks that read source files from dependencies but don't need their build outputs.
## Missing outputs for File-Producing Tasks
**Before flagging missing `outputs`, check what the task actually produces:**
1. Read the package's script (e.g., `"build": "tsc"`, `"test": "vitest"`)
2. Determine if it writes files to disk or only outputs to stdout
3. Only flag if the task produces files that should be cached
```json
// WRONG - build produces files but they're not cached
"build": {
"dependsOn": ["^build"]
}
// CORRECT - outputs are cached
"build": {
"dependsOn": ["^build"],
"outputs": ["dist/**"]
}
```
No `outputs` key is fine for stdout-only tasks. For file-producing tasks, missing `outputs` means Turbo has nothing to cache.
## Forgetting ^ in dependsOn
```json
// WRONG - looks for "build" in SAME package (infinite loop or missing)
"build": {
"dependsOn": ["build"]
}
// CORRECT - runs dependencies' build first
"build": {
"dependsOn": ["^build"]
}
```
The `^` means "in dependency packages", not "in this package".
## Missing persistent on Dev Tasks
```json
// WRONG - dependent tasks hang waiting for dev to "finish"
"dev": {
"cache": false
}
// CORRECT
"dev": {
"cache": false,
"persistent": true
}
```
## Package Config Missing extends
```json
// WRONG - packages/web/turbo.json
{
"tasks": {
"build": { "outputs": [".next/**"] }
}
}
// CORRECT
{
"extends": ["//"],
"tasks": {
"build": { "outputs": [".next/**"] }
}
}
```
Without `"extends": ["//"]`, Package Configurations are invalid.
## Root Tasks Need Special Syntax
To run a task defined only in root `package.json`:
```bash
# WRONG
turbo run format
# CORRECT
turbo run //#format
```
And in dependsOn:
```json
"build": {
"dependsOn": ["//#codegen"] // Root package's codegen
}
```
## Overwriting Default Inputs
```json
// WRONG - only watches test files, ignores source changes
"test": {
"inputs": ["tests/**"]
}
// CORRECT - extends defaults, adds test files
"test": {
"inputs": ["$TURBO_DEFAULT$", "tests/**"]
}
```
Without `$TURBO_DEFAULT$`, you replace all default file watching.
## Caching Tasks with Side Effects
```json
// WRONG - deploy might be skipped on cache hit
"deploy": {
"dependsOn": ["build"]
}
// CORRECT
"deploy": {
"dependsOn": ["build"],
"cache": false
}
```
Always disable cache for deploy, publish, or mutation tasks.

# Task Configuration Reference
Full docs: https://turborepo.dev/docs/reference/configuration#tasks
## dependsOn
Controls task execution order.
```json
{
"tasks": {
"build": {
"dependsOn": [
"^build", // Dependencies' build tasks first
"codegen", // Same package's codegen task first
"shared#build" // Specific package's build task
]
}
}
}
```
| Syntax | Meaning |
| ---------- | ------------------------------------ |
| `^task` | Run `task` in all dependencies first |
| `task` | Run `task` in same package first |
| `pkg#task` | Run specific package's task first |
The `^` prefix is crucial - without it, you're referencing the same package.
### Transit Nodes for Parallel Tasks
For tasks like `lint` and `check-types` that can run in parallel but need dependency-aware caching:
```json
{
"tasks": {
"transit": { "dependsOn": ["^transit"] },
"lint": { "dependsOn": ["transit"] },
"check-types": { "dependsOn": ["transit"] }
}
}
```
**DO NOT use `dependsOn: ["^lint"]`** - this forces sequential execution.
**DO NOT use `dependsOn: []`** - this breaks cache invalidation.
The `transit` task creates dependency relationships without running anything (no matching script), so tasks run in parallel with correct caching.
## outputs
Glob patterns for files to cache. **If omitted, nothing is cached.**
```json
{
"tasks": {
"build": {
"outputs": ["dist/**", "build/**"]
}
}
}
```
**Framework examples:**
```json
// Next.js
"outputs": [".next/**", "!.next/cache/**"]
// Vite
"outputs": ["dist/**"]
// TypeScript (tsc)
"outputs": ["dist/**", "*.tsbuildinfo"]
// No file outputs (lint, typecheck)
"outputs": []
```
Use `!` prefix to exclude patterns from caching.
## inputs
Files considered when calculating task hash. Defaults to all tracked files in package.
```json
{
"tasks": {
"test": {
"inputs": ["src/**", "tests/**", "vitest.config.ts"]
}
}
}
```
**Special values:**
| Value | Meaning |
| --------------------- | --------------------------------------- |
| `$TURBO_DEFAULT$` | Include default inputs, then add/remove |
| `$TURBO_ROOT$/<path>` | Reference files from repo root |
```json
{
"tasks": {
"build": {
"inputs": [
"$TURBO_DEFAULT$",
"!README.md",
"$TURBO_ROOT$/tsconfig.base.json"
]
}
}
}
```
## env
Environment variables to include in task hash.
```json
{
"tasks": {
"build": {
"env": [
"API_URL",
"NEXT_PUBLIC_*", // Wildcard matching
"!DEBUG" // Exclude from hash
]
}
}
}
```
Variables listed here affect cache hits - changing the value invalidates cache.
## cache
Enable/disable caching for a task. Default: `true`.
```json
{
"tasks": {
"dev": { "cache": false },
"deploy": { "cache": false }
}
}
```
Disable for: dev servers, deploy commands, tasks with side effects.
## persistent
Mark long-running tasks that don't exit. Default: `false`.
```json
{
"tasks": {
"dev": {
"cache": false,
"persistent": true
}
}
}
```
Required for dev servers - without it, dependent tasks wait forever.
## interactive
Allow task to receive stdin input. Default: `false`.
```json
{
"tasks": {
"login": {
"cache": false,
"interactive": true
}
}
}
```
## outputLogs
Control when logs are shown. Options: `full`, `hash-only`, `new-only`, `errors-only`, `none`.
```json
{
"tasks": {
"build": {
"outputLogs": "new-only" // Only show logs on cache miss
}
}
}
```
## with
Run tasks alongside this task. For long-running tasks that need runtime dependencies.
```json
{
"tasks": {
"dev": {
"with": ["api#dev"],
"persistent": true,
"cache": false
}
}
}
```
Unlike `dependsOn`, `with` runs tasks concurrently (not sequentially). Use for dev servers that need other services running.
## interruptible
Allow `turbo watch` to restart the task on changes. Default: `false`.
```json
{
"tasks": {
"dev": {
"persistent": true,
"interruptible": true,
"cache": false
}
}
}
```
Use for dev servers that don't automatically detect dependency changes.
## description (Pre-release)
Human-readable description of the task.
```json
{
"tasks": {
"build": {
"description": "Compiles the application for production deployment"
}
}
}
```
For documentation only - doesn't affect execution or caching.
## passThroughEnv
Environment variables available at runtime but NOT included in cache hash.
```json
{
"tasks": {
"build": {
"passThroughEnv": ["AWS_SECRET_KEY", "GITHUB_TOKEN"]
}
}
}
```
**Warning**: Changes to these vars won't cause cache misses. Use `env` if changes should invalidate cache.
## extends (Package Configuration only)
Control task inheritance in Package Configurations.
```json
// packages/ui/turbo.json
{
"extends": ["//"],
"tasks": {
"lint": {
"extends": false // Exclude from this package
}
}
}
```
| Value | Behavior |
| ---------------- | -------------------------------------------------------------- |
| `true` (default) | Inherit from root turbo.json |
| `false` | Exclude task from package, or define fresh without inheritance |

# Environment Variable Gotchas
Common mistakes and how to fix them.
## .env Files Must Be in `inputs`
Turbo does NOT read `.env` files. Your framework (Next.js, Vite, etc.) or `dotenv` loads them. But Turbo needs to know when they change.
**Wrong:**
```json
{
"tasks": {
"build": {
"env": ["DATABASE_URL"]
}
}
}
```
**Right:**
```json
{
"tasks": {
"build": {
"env": ["DATABASE_URL"],
"inputs": ["$TURBO_DEFAULT$", ".env", ".env.local", ".env.production"]
}
}
}
```
## Strict Mode Filters CI Variables
In strict mode, CI provider variables (GITHUB_TOKEN, GITLAB_CI, etc.) are filtered unless explicitly listed.
**Symptom:** Task fails with "authentication required" or "permission denied" in CI.
**Solution:**
```json
{
"globalPassThroughEnv": ["GITHUB_TOKEN", "GITLAB_CI", "CI"]
}
```
## passThroughEnv Doesn't Affect Hash
Variables in `passThroughEnv` are available at runtime but changes WON'T trigger rebuilds.
**Dangerous example:**
```json
{
"tasks": {
"build": {
"passThroughEnv": ["API_URL"]
}
}
}
```
If `API_URL` changes from staging to production, Turbo may serve a cached build pointing to the wrong API.
**Use passThroughEnv only for:**
- Auth tokens that don't affect output (SENTRY_AUTH_TOKEN)
- CI metadata (GITHUB_RUN_ID)
- Variables consumed after build (deploy credentials)
## Runtime-Created Variables Are Invisible
Turbo captures env vars at startup. Variables created during execution aren't seen.
**Won't work:**
```bash
# In package.json scripts
"build": "export API_URL=$COMPUTED_VALUE && next build"
```
**Solution:** Set vars before invoking turbo:
```bash
API_URL=$COMPUTED_VALUE turbo run build
```
## Different .env Files for Different Environments
If you use `.env.development` and `.env.production`, both should be in inputs.
```json
{
"tasks": {
"build": {
"inputs": [
"$TURBO_DEFAULT$",
".env",
".env.local",
".env.development",
".env.development.local",
".env.production",
".env.production.local"
]
}
}
}
```
## Complete Next.js Example
```json
{
"$schema": "https://turborepo.dev/schema.v2.json",
"globalEnv": ["CI", "NODE_ENV", "VERCEL"],
"globalPassThroughEnv": ["GITHUB_TOKEN", "VERCEL_URL"],
"tasks": {
"build": {
"dependsOn": ["^build"],
"env": [
"DATABASE_URL",
"NEXT_PUBLIC_*",
"!NEXT_PUBLIC_ANALYTICS_ID"
],
"passThroughEnv": ["SENTRY_AUTH_TOKEN"],
"inputs": [
"$TURBO_DEFAULT$",
".env",
".env.local",
".env.production",
".env.production.local"
],
"outputs": [".next/**", "!.next/cache/**"]
}
}
}
```
This config:
- Hashes DATABASE*URL and NEXT_PUBLIC*\* vars (except analytics)
- Passes through SENTRY_AUTH_TOKEN without hashing
- Includes all .env file variants in the hash
- Makes CI tokens available globally

# Environment Modes
Turborepo supports different modes for handling environment variables during task execution.
## Strict Mode (Default)
Only explicitly configured variables are available to tasks.
**Behavior:**
- Tasks only see vars listed in `env`, `globalEnv`, `passThroughEnv`, or `globalPassThroughEnv`
- Unlisted vars are filtered out
- Tasks fail if they require unlisted variables
**Benefits:**
- Guarantees cache correctness
- Prevents accidental dependencies on system vars
- Reproducible builds across machines
```bash
# Explicit (though it's the default)
turbo run build --env-mode=strict
```
## Loose Mode
All system environment variables are available to tasks.
```bash
turbo run build --env-mode=loose
```
**Behavior:**
- Every system env var is passed through
- Only vars in `env`/`globalEnv` affect the hash
- Other vars are available but NOT hashed
**Risks:**
- Cache may restore incorrect results if unhashed vars changed
- "Works on my machine" bugs
- CI vs local environment mismatches
**Use case:** Migrating legacy projects or debugging strict mode issues.
## Framework Inference (Automatic)
Turborepo automatically detects frameworks and includes their conventional env vars.
### Inferred Variables by Framework
| Framework | Pattern |
| ---------------- | ------------------- |
| Next.js | `NEXT_PUBLIC_*` |
| Vite | `VITE_*` |
| Create React App | `REACT_APP_*` |
| Gatsby | `GATSBY_*` |
| Nuxt | `NUXT_*`, `NITRO_*` |
| Expo | `EXPO_PUBLIC_*` |
| Astro | `PUBLIC_*` |
| SvelteKit | `PUBLIC_*` |
| Remix | `REMIX_*` |
| Redwood | `REDWOOD_ENV_*` |
| Sanity | `SANITY_STUDIO_*` |
| Solid | `VITE_*` |
### Disabling Framework Inference
Globally via CLI:
```bash
turbo run build --framework-inference=false
```
Or exclude specific patterns in config:
```json
{
"tasks": {
"build": {
"env": ["!NEXT_PUBLIC_*"]
}
}
}
```
### Why Disable?
- You want explicit control over all env vars
- Framework vars shouldn't bust the cache (e.g., analytics IDs)
- Debugging unexpected cache misses
## Checking Environment Mode
Use `--dry` to see which vars affect each task:
```bash
turbo run build --dry=json | jq '.tasks[].environmentVariables'
```

# Common Filter Patterns
Practical examples for typical monorepo scenarios.
## Single Package
Run task in one package:
```bash
turbo run build --filter=web
turbo run test --filter=@acme/api
```
## Package with Dependencies
Build a package and everything it depends on:
```bash
turbo run build --filter=web...
```
Useful for: ensuring all dependencies are built before the target.
## Package Dependents
Run in all packages that depend on a library:
```bash
turbo run test --filter=...ui
```
Useful for: testing consumers after changing a shared package.
## Dependents Only (Exclude Target)
Test packages that depend on ui, but not ui itself:
```bash
turbo run test --filter=...^ui
```
## Changed Packages
Run only in packages with file changes since last commit:
```bash
turbo run lint --filter=[HEAD^1]
```
Since a specific branch point:
```bash
turbo run lint --filter=[main...HEAD]
```
## Changed + Dependents (PR Builds)
Run in changed packages AND packages that depend on them:
```bash
turbo run build test --filter=...[HEAD^1]
```
Or use the shortcut:
```bash
turbo run build test --affected
```
## Directory-Based
Run in all apps:
```bash
turbo run build --filter=./apps/*
```
Run in specific directories:
```bash
turbo run build --filter=./apps/web --filter=./apps/api
```
## Scope-Based
Run in all packages under a scope:
```bash
turbo run build --filter=@acme/*
```
## Exclusions
Run in all apps except admin:
```bash
turbo run build --filter=./apps/* --filter=!admin
```
Run everywhere except specific packages:
```bash
turbo run lint --filter=!legacy-app --filter=!deprecated-pkg
```
## Complex Combinations
Apps that changed, plus their dependents:
```bash
turbo run build --filter=...[HEAD^1] --filter=./apps/*
```
All packages except docs, but only if changed:
```bash
turbo run build --filter=[main...HEAD] --filter=!docs
```
## Debugging Filters
Use `--dry` to see what would run without executing:
```bash
turbo run build --filter=web... --dry
```
Use `--dry=json` for machine-readable output:
```bash
turbo run build --filter=...[HEAD^1] --dry=json
```
## CI/CD Patterns
PR validation (most common):
```bash
turbo run build test lint --affected
```

# TypeScript Expert
You are an advanced TypeScript expert with deep, practical knowledge of type-level programming, performance optimization, and real-world problem solving based on current best practices.
## When invoked:
0. If the issue requires ultra-specific expertise, recommend switching and stop:
- Deep webpack/vite/rollup bundler internals → typescript-build-expert
- Complex ESM/CJS migration or circular dependency analysis → typescript-module-expert
- Type performance profiling or compiler internals → typescript-type-expert
Example to output:
"This requires deep bundler expertise. Please invoke: 'Use the typescript-build-expert subagent.' Stopping here."
1. Analyze project setup comprehensively:
**Use internal tools first (Read, Grep, Glob) for better performance. Shell commands are fallbacks.**
```bash
# Core versions and configuration
npx tsc --version
node -v
# Detect tooling ecosystem (prefer parsing package.json)
node -e "const p=require('./package.json');console.log(Object.keys({...p.devDependencies,...p.dependencies}||{}).join('\n'))" 2>/dev/null | grep -E 'biome|eslint|prettier|vitest|jest|turborepo|nx' || echo "No tooling detected"
# Check for monorepo (fixed precedence)
(test -f pnpm-workspace.yaml || test -f lerna.json || test -f nx.json || test -f turbo.json) && echo "Monorepo detected"
```
**After detection, adapt approach:**
- Match import style (absolute vs relative)
- Respect existing baseUrl/paths configuration
- Prefer existing project scripts over raw tools
- In monorepos, consider project references before broad tsconfig changes
2. Identify the specific problem category and complexity level
3. Apply the appropriate solution strategy from my expertise
4. Validate thoroughly:
```bash
# Fast fail approach (avoid long-lived processes)
npm run -s typecheck || npx tsc --noEmit
npm test -s || npx vitest run --reporter=basic --no-watch
# Only if needed and build affects outputs/config
npm run -s build
```
**Safety note:** Avoid watch/serve processes in validation. Use one-shot diagnostics only.
## Advanced Type System Expertise
### Type-Level Programming Patterns
**Branded Types for Domain Modeling**
```typescript
// Create nominal types to prevent primitive obsession
type Brand<K, T> = K & { __brand: T };
type UserId = Brand<string, 'UserId'>;
type OrderId = Brand<string, 'OrderId'>;
// Prevents accidental mixing of domain primitives
function processOrder(orderId: OrderId, userId: UserId) { }
```
- Use for: Critical domain primitives, API boundaries, currency/units
- Resource: https://egghead.io/blog/using-branded-types-in-typescript
**Advanced Conditional Types**
```typescript
// Recursive type manipulation
type DeepReadonly<T> = T extends (...args: any[]) => any
? T
: T extends object
? { readonly [K in keyof T]: DeepReadonly<T[K]> }
: T;
// Template literal type magic
type PropEventSource<Type> = {
on<Key extends string & keyof Type>
(eventName: `${Key}Changed`, callback: (newValue: Type[Key]) => void): void;
};
```
- Use for: Library APIs, type-safe event systems, compile-time validation
- Watch for: Type instantiation depth errors (limit recursion to 10 levels)
**Type Inference Techniques**
```typescript
// Use 'satisfies' for constraint validation (TS 5.0+)
const config = {
api: "https://api.example.com",
timeout: 5000
} satisfies Record<string, string | number>;
// Preserves literal types while ensuring constraints
// Const assertions for maximum inference
const routes = ['/home', '/about', '/contact'] as const;
type Route = typeof routes[number]; // '/home' | '/about' | '/contact'
```
### Performance Optimization Strategies
**Type Checking Performance**
```bash
# Diagnose slow type checking
npx tsc --extendedDiagnostics --incremental false | grep -E "Check time|Files:|Lines:|Nodes:"
# Common fixes for "Type instantiation is excessively deep"
# 1. Replace type intersections with interfaces
# 2. Split large union types (>100 members)
# 3. Avoid circular generic constraints
# 4. Use type aliases to break recursion
```
**Build Performance Patterns**
- Enable `skipLibCheck: true` for library type checking only (often significantly improves performance on large projects, but avoid masking app typing issues)
- Use `incremental: true` with `.tsbuildinfo` cache
- Configure `include`/`exclude` precisely
- For monorepos: Use project references with `composite: true`
## Real-World Problem Resolution
### Complex Error Patterns
**"The inferred type of X cannot be named"**
- Cause: Missing type export or circular dependency
- Fix priority:
1. Export the required type explicitly
2. Use `ReturnType<typeof function>` helper
3. Break circular dependencies with type-only imports
- Resource: https://github.com/microsoft/TypeScript/issues/47663
**Missing type declarations**
- Quick fix with ambient declarations:
```typescript
// types/ambient.d.ts
declare module 'some-untyped-package' {
const value: unknown;
export default value;
export = value; // if CJS interop is needed
}
```
- For more details: [Declaration Files Guide](https://www.typescriptlang.org/docs/handbook/declaration-files/introduction.html)
**"Excessive stack depth comparing types"**
- Cause: Circular or deeply recursive types
- Fix priority:
1. Limit recursion depth with conditional types
2. Use `interface` extends instead of type intersection
3. Simplify generic constraints
```typescript
// Bad: Infinite recursion
type InfiniteArray<T> = T | InfiniteArray<T>[];
// Good: Limited recursion
type NestedArray<T, D extends number = 5> =
D extends 0 ? T : T | NestedArray<T, [-1, 0, 1, 2, 3, 4][D]>[];
```
**Module Resolution Mysteries**
- "Cannot find module" despite file existing:
1. Check `moduleResolution` matches your bundler
2. Verify `baseUrl` and `paths` alignment
3. For monorepos: Ensure workspace protocol (workspace:*)
4. Try clearing cache: `rm -rf node_modules/.cache .tsbuildinfo`
**Path Mapping at Runtime**
- TypeScript paths only work at compile time, not runtime
- Node.js runtime solutions:
- ts-node: Use `ts-node -r tsconfig-paths/register`
- Node ESM: Use loader alternatives or avoid TS paths at runtime
- Production: Pre-compile with resolved paths
### Migration Expertise
**JavaScript to TypeScript Migration**
```bash
# Incremental migration strategy
# 1. Enable allowJs and checkJs (merge into existing tsconfig.json):
# Add to existing tsconfig.json:
# {
# "compilerOptions": {
# "allowJs": true,
# "checkJs": true
# }
# }
# 2. Rename files gradually (.js → .ts)
# 3. Add types file by file using AI assistance
# 4. Enable strict mode features one by one
# Automated helpers (if installed/needed)
command -v ts-migrate >/dev/null 2>&1 && npx ts-migrate migrate . --sources 'src/**/*.js'
command -v typesync >/dev/null 2>&1 && npx typesync # Install missing @types packages
```
**Tool Migration Decisions**
| From | To | When | Migration Effort |
|------|-----|------|-----------------|
| ESLint + Prettier | Biome | Need much faster speed, okay with fewer rules | Low (1 day) |
| TSC for linting | Type-check only | Have 100+ files, need faster feedback | Medium (2-3 days) |
| Lerna | Nx/Turborepo | Need caching, parallel builds | High (1 week) |
| CJS | ESM | Node 18+, modern tooling | High (varies) |
### Monorepo Management
**Nx vs Turborepo Decision Matrix**
- Choose **Turborepo** if: Simple structure, need speed, <20 packages
- Choose **Nx** if: Complex dependencies, need visualization, plugins required
- Performance: Nx often performs better on large monorepos (>50 packages)
**TypeScript Monorepo Configuration**
```json
// Root tsconfig.json
{
"references": [
{ "path": "./packages/core" },
{ "path": "./packages/ui" },
{ "path": "./apps/web" }
],
"compilerOptions": {
"composite": true,
"declaration": true,
"declarationMap": true
}
}
```
## Modern Tooling Expertise
### Biome vs ESLint
**Use Biome when:**
- Speed is critical (often faster than traditional setups)
- Want single tool for lint + format
- TypeScript-first project
- Okay with 64 TS rules vs 100+ in typescript-eslint
**Stay with ESLint when:**
- Need specific rules/plugins
- Have complex custom rules
- Working with Vue/Angular (limited Biome support)
- Need type-aware linting (Biome doesn't have this yet)
### Type Testing Strategies
**Vitest Type Testing (Recommended)**
```typescript
// in avatar.test-d.ts
import { expectTypeOf } from 'vitest'
import type { Avatar } from './avatar'
test('Avatar props are correctly typed', () => {
expectTypeOf<Avatar>().toHaveProperty('size')
expectTypeOf<Avatar['size']>().toEqualTypeOf<'sm' | 'md' | 'lg'>()
})
```
**When to Test Types:**
- Publishing libraries
- Complex generic functions
- Type-level utilities
- API contracts
## Debugging Mastery
### CLI Debugging Tools
```bash
# Debug TypeScript files directly (if tools installed)
command -v tsx >/dev/null 2>&1 && npx tsx --inspect src/file.ts
command -v ts-node >/dev/null 2>&1 && npx ts-node --inspect-brk src/file.ts
# Trace module resolution issues
npx tsc --traceResolution > resolution.log 2>&1
grep "Module resolution" resolution.log
# Debug type checking performance (use --incremental false for clean trace)
npx tsc --generateTrace trace --incremental false
# Analyze trace (if installed)
command -v @typescript/analyze-trace >/dev/null 2>&1 && npx @typescript/analyze-trace trace
# Memory usage analysis
node --max-old-space-size=8192 node_modules/typescript/lib/tsc.js
```
### Custom Error Classes
```typescript
// Proper error class with stack preservation
class DomainError extends Error {
constructor(
message: string,
public code: string,
public statusCode: number
) {
super(message);
this.name = 'DomainError';
Error.captureStackTrace(this, this.constructor);
}
}
```
## Current Best Practices
### Strict by Default
```json
{
"compilerOptions": {
"strict": true,
"noUncheckedIndexedAccess": true,
"noImplicitOverride": true,
"exactOptionalPropertyTypes": true,
"noPropertyAccessFromIndexSignature": true
}
}
```
### ESM-First Approach
- Set `"type": "module"` in package.json
- Use `.mts` for TypeScript ESM files if needed
- Configure `"moduleResolution": "bundler"` for modern tools
- Use dynamic imports for CJS: `const pkg = await import('cjs-package')`
- Note: `await import()` requires async function or top-level await in ESM
- For CJS packages in ESM: May need `(await import('pkg')).default` depending on the package's export structure and your compiler settings
### AI-Assisted Development
- GitHub Copilot excels at TypeScript generics
- Use AI for boilerplate type definitions
- Validate AI-generated types with type tests
- Document complex types for AI context
## Code Review Checklist
When reviewing TypeScript/JavaScript code, focus on these domain-specific aspects:
### Type Safety
- [ ] No implicit `any` types (use `unknown` or proper types)
- [ ] Strict null checks enabled and properly handled
- [ ] Type assertions (`as`) justified and minimal
- [ ] Generic constraints properly defined
- [ ] Discriminated unions for error handling
- [ ] Return types explicitly declared for public APIs
### TypeScript Best Practices
- [ ] Prefer `interface` over `type` for object shapes (better error messages)
- [ ] Use const assertions for literal types
- [ ] Leverage type guards and predicates
- [ ] Avoid type gymnastics when simpler solution exists
- [ ] Template literal types used appropriately
- [ ] Branded types for domain primitives
### Performance Considerations
- [ ] Type complexity doesn't cause slow compilation
- [ ] No excessive type instantiation depth
- [ ] Avoid complex mapped types in hot paths
- [ ] Use `skipLibCheck: true` in tsconfig
- [ ] Project references configured for monorepos
### Module System
- [ ] Consistent import/export patterns
- [ ] No circular dependencies
- [ ] Proper use of barrel exports (avoid over-bundling)
- [ ] ESM/CJS compatibility handled correctly
- [ ] Dynamic imports for code splitting
### Error Handling Patterns
- [ ] Result types or discriminated unions for errors
- [ ] Custom error classes with proper inheritance
- [ ] Type-safe error boundaries
- [ ] Exhaustive switch cases with `never` type
### Code Organization
- [ ] Types co-located with implementation
- [ ] Shared types in dedicated modules
- [ ] Avoid global type augmentation when possible
- [ ] Proper use of declaration files (.d.ts)
## Quick Decision Trees
### "Which tool should I use?"
```
Type checking only? → tsc
Type checking + linting speed critical? → Biome
Type checking + comprehensive linting? → ESLint + typescript-eslint
Type testing? → Vitest expectTypeOf
Build tool? → Project size <10 packages? Turborepo. Else? Nx
```
### "How do I fix this performance issue?"
```
Slow type checking? → skipLibCheck, incremental, project references
Slow builds? → Check bundler config, enable caching
Slow tests? → Vitest with threads, avoid type checking in tests
Slow language server? → Exclude node_modules, limit files in tsconfig
```

# TypeScript Cheatsheet
## Type Basics
```typescript
// Primitives
const name: string = 'John'
const age: number = 30
const isActive: boolean = true
const nothing: null = null
const notDefined: undefined = undefined
// Arrays
const numbers: number[] = [1, 2, 3]
const strings: Array<string> = ['a', 'b', 'c']
// Tuple
const tuple: [string, number] = ['hello', 42]
// Object
const user: { name: string; age: number } = { name: 'John', age: 30 }
// Union
const value: string | number = 'hello'
// Literal
const direction: 'up' | 'down' | 'left' | 'right' = 'up'
// Any vs Unknown
const anyValue: any = 'anything' // ❌ Avoid
const unknownValue: unknown = 'safe' // ✅ Prefer, requires narrowing
```
## Type Aliases & Interfaces
```typescript
// Type Alias
type Point = {
x: number
y: number
}
// Interface (preferred for objects)
interface User {
id: string
name: string
email?: string // Optional
readonly createdAt: Date // Readonly
}
// Extending
interface Admin extends User {
permissions: string[]
}
// Intersection
type AdminUser = User & { permissions: string[] }
```
## Generics
```typescript
// Generic function
function identity<T>(value: T): T {
return value
}
// Generic with constraint
function getLength<T extends { length: number }>(item: T): number {
return item.length
}
// Generic interface
interface ApiResponse<T> {
data: T
status: number
message: string
}
// Generic with default
type Container<T = string> = {
value: T
}
// Multiple generics
function merge<T, U>(obj1: T, obj2: U): T & U {
return { ...obj1, ...obj2 }
}
```
## Utility Types
```typescript
interface User {
id: string
name: string
email: string
age: number
}
// Partial - all optional
type PartialUser = Partial<User>
// Required - all required
type RequiredUser = Required<User>
// Readonly - all readonly
type ReadonlyUser = Readonly<User>
// Pick - select properties
type UserName = Pick<User, 'id' | 'name'>
// Omit - exclude properties
type UserWithoutEmail = Omit<User, 'email'>
// Record - key-value map
type UserMap = Record<string, User>
// Extract - extract from union
type StringOrNumber = string | number | boolean
type OnlyStrings = Extract<StringOrNumber, string>
// Exclude - exclude from union
type NotString = Exclude<StringOrNumber, string>
// NonNullable - remove null/undefined
type MaybeString = string | null | undefined
type DefinitelyString = NonNullable<MaybeString>
// ReturnType - get function return type
function getUser() { return { name: 'John' } }
type UserReturn = ReturnType<typeof getUser>
// Parameters - get function parameters
type GetUserParams = Parameters<typeof getUser>
// Awaited - unwrap Promise
type ResolvedUser = Awaited<Promise<User>>
```
## Conditional Types
```typescript
// Basic conditional
type IsString<T> = T extends string ? true : false
// Infer keyword
type UnwrapPromise<T> = T extends Promise<infer U> ? U : T
// Distributive conditional
type ToArray<T> = T extends any ? T[] : never
type Result = ToArray<string | number> // string[] | number[]
// NonDistributive
type ToArrayNonDist<T> = [T] extends [any] ? T[] : never
```
## Template Literal Types
```typescript
type Color = 'red' | 'green' | 'blue'
type Size = 'small' | 'medium' | 'large'
// Combine
type ColorSize = `${Color}-${Size}`
// 'red-small' | 'red-medium' | 'red-large' | ...
// Event handlers
type EventName = 'click' | 'focus' | 'blur'
type EventHandler = `on${Capitalize<EventName>}`
// 'onClick' | 'onFocus' | 'onBlur'
```
## Mapped Types
```typescript
// Basic mapped type
type Optional<T> = {
[K in keyof T]?: T[K]
}
// With key remapping
type Getters<T> = {
[K in keyof T as `get${Capitalize<string & K>}`]: () => T[K]
}
// Filter keys
type OnlyStrings<T> = {
[K in keyof T as T[K] extends string ? K : never]: T[K]
}
```
## Type Guards
```typescript
// typeof guard
function process(value: string | number) {
if (typeof value === 'string') {
return value.toUpperCase() // string
}
return value.toFixed(2) // number
}
// instanceof guard
class Dog { bark() {} }
class Cat { meow() {} }
function makeSound(animal: Dog | Cat) {
if (animal instanceof Dog) {
animal.bark()
} else {
animal.meow()
}
}
// in guard
interface Bird { fly(): void }
interface Fish { swim(): void }
function move(animal: Bird | Fish) {
if ('fly' in animal) {
animal.fly()
} else {
animal.swim()
}
}
// Custom type guard
function isString(value: unknown): value is string {
return typeof value === 'string'
}
// Assertion function
function assertIsString(value: unknown): asserts value is string {
if (typeof value !== 'string') {
throw new Error('Not a string')
}
}
```
## Discriminated Unions
```typescript
// With type discriminant
type Success<T> = { type: 'success'; data: T }
type Error = { type: 'error'; message: string }
type Loading = { type: 'loading' }
type State<T> = Success<T> | Error | Loading
function handle<T>(state: State<T>) {
switch (state.type) {
case 'success':
return state.data // T
case 'error':
return state.message // string
case 'loading':
return null
}
}
// Exhaustive check
function assertNever(value: never): never {
throw new Error(`Unexpected value: ${value}`)
}
```
## Branded Types
```typescript
// Create branded type
type Brand<K, T> = K & { __brand: T }
type UserId = Brand<string, 'UserId'>
type OrderId = Brand<string, 'OrderId'>
// Constructor functions
function createUserId(id: string): UserId {
return id as UserId
}
function createOrderId(id: string): OrderId {
return id as OrderId
}
// Usage - prevents mixing
function getOrder(orderId: OrderId, userId: UserId) {}
const userId = createUserId('user-123')
const orderId = createOrderId('order-456')
getOrder(orderId, userId) // ✅ OK
// getOrder(userId, orderId) // ❌ Error - types don't match
```
## Module Declarations
```typescript
// Declare module for untyped package
declare module 'untyped-package' {
export function doSomething(): void
export const value: string
}
// Augment existing module
declare module 'express' {
interface Request {
user?: { id: string }
}
}
// Declare global
declare global {
interface Window {
myGlobal: string
}
}
```
## TSConfig Essentials
```json
{
"compilerOptions": {
// Strictness
"strict": true,
"noUncheckedIndexedAccess": true,
"noImplicitOverride": true,
// Modules
"module": "ESNext",
"moduleResolution": "bundler",
"esModuleInterop": true,
// Output
"target": "ES2022",
"lib": ["ES2022", "DOM"],
// Performance
"skipLibCheck": true,
"incremental": true,
// Paths
"baseUrl": ".",
"paths": {
"@/*": ["./src/*"]
}
}
}
```
## Best Practices
```typescript
// ✅ Prefer interface for objects
interface User {
name: string
}
// ✅ Use const assertions
const routes = ['home', 'about'] as const
// ✅ Use satisfies for validation
const config = {
api: 'https://api.example.com'
} satisfies Record<string, string>
// ✅ Use unknown over any
function parse(input: unknown) {
if (typeof input === 'string') {
return JSON.parse(input)
}
}
// ✅ Explicit return types for public APIs
export function getUser(id: string): User | null {
// ...
}
// ❌ Avoid
const data: any = fetchData()
data.anything.goes.wrong // No type safety

name: web-perf
description: Analyzes web performance using Chrome DevTools MCP. Measures Core Web Vitals (FCP, LCP, TBT, CLS, Speed Index), identifies render-blocking resources, network dependency chains, layout shifts, caching issues, and accessibility gaps. Use when asked to audit, profile, debug, or optimize page load performance, Lighthouse scores, or site speed.
---
# Web Performance Audit
Audit web page performance using Chrome DevTools MCP tools. This skill focuses on Core Web Vitals, network optimization, and high-level accessibility gaps.
## FIRST: Verify MCP Tools Available
**Run this before starting.** Try calling `navigate_page` or `performance_start_trace`. If unavailable, STOP—the chrome-devtools MCP server isn't configured.
Ask the user to add this to their MCP config:
```json
"chrome-devtools": {
"type": "local",
"command": ["npx", "-y", "chrome-devtools-mcp@latest"]
}
```
## Key Guidelines
- **Be assertive**: Verify claims by checking network requests, DOM, or codebase—then state findings definitively.
- **Verify before recommending**: Confirm something is unused before suggesting removal.
- **Quantify impact**: Use estimated savings from insights. Don't prioritize changes with 0ms impact.
- **Skip non-issues**: If render-blocking resources have 0ms estimated impact, note but don't recommend action.
- **Be specific**: Say "compress hero.png (450KB) to WebP" not "optimize images".
- **Prioritize ruthlessly**: A site with 200ms LCP and 0 CLS is already excellent—say so.
## Quick Reference
| Task | Tool Call |
|------|-----------|
| Load page | `navigate_page(url: "...")` |
| Start trace | `performance_start_trace(autoStop: true, reload: true)` |
| Analyze insight | `performance_analyze_insight(insightSetId: "...", insightName: "...")` |
| List requests | `list_network_requests(resourceTypes: ["Script", "Stylesheet", ...])` |
| Request details | `get_network_request(reqid: <id>)` |
| A11y snapshot | `take_snapshot(verbose: true)` |
## Workflow
Copy this checklist to track progress:
```
Audit Progress:
- [ ] Phase 1: Performance trace (navigate + record)
- [ ] Phase 2: Core Web Vitals analysis (includes CLS culprits)
- [ ] Phase 3: Network analysis
- [ ] Phase 4: Accessibility snapshot
- [ ] Phase 5: Codebase analysis (skip if third-party site)
```
### Phase 1: Performance Trace
1. Navigate to the target URL:
```
navigate_page(url: "<target-url>")
```
2. Start a performance trace with reload to capture cold-load metrics:
```
performance_start_trace(autoStop: true, reload: true)
```
3. Wait for trace completion, then retrieve results.
**Troubleshooting:**
- If trace returns empty or fails, verify the page loaded correctly with `navigate_page` first
- If insight names don't match, inspect the trace response to list available insights
### Phase 2: Core Web Vitals Analysis
Use `performance_analyze_insight` to extract key metrics.
**Note:** Insight names may vary across Chrome DevTools versions. If an insight name doesn't work, check the `insightSetId` from the trace response to discover available insights.
Common insight names:
| Metric | Insight Name | What to Look For |
|--------|--------------|------------------|
| LCP | `LCPBreakdown` | Time to largest contentful paint; breakdown of TTFB, resource load, render delay |
| CLS | `CLSCulprits` | Elements causing layout shifts (images without dimensions, injected content, font swaps) |
| Render Blocking | `RenderBlocking` | CSS/JS blocking first paint |
| Document Latency | `DocumentLatency` | Server response time issues |
| Network Dependencies | `NetworkRequestsDepGraph` | Request chains delaying critical resources |
Example:
```
performance_analyze_insight(insightSetId: "<id-from-trace>", insightName: "LCPBreakdown")
```
**Key thresholds (good/needs-improvement/poor):**
- TTFB: < 800ms / < 1.8s / > 1.8s
- FCP: < 1.8s / < 3s / > 3s
- LCP: < 2.5s / < 4s / > 4s
- INP: < 200ms / < 500ms / > 500ms
- TBT: < 200ms / < 600ms / > 600ms
- CLS: < 0.1 / < 0.25 / > 0.25
- Speed Index: < 3.4s / < 5.8s / > 5.8s
### Phase 3: Network Analysis
List all network requests to identify optimization opportunities:
```
list_network_requests(resourceTypes: ["Script", "Stylesheet", "Document", "Font", "Image"])
```
**Look for:**
1. **Render-blocking resources**: JS/CSS in `<head>` without `async`/`defer`/`media` attributes
2. **Network chains**: Resources discovered late because they depend on other resources loading first (e.g., CSS imports, JS-loaded fonts)
3. **Missing preloads**: Critical resources (fonts, hero images, key scripts) not preloaded
4. **Caching issues**: Missing or weak `Cache-Control`, `ETag`, or `Last-Modified` headers
5. **Large payloads**: Uncompressed or oversized JS/CSS bundles
6. **Unused preconnects**: If flagged, verify by checking if ANY requests went to that origin. If zero requests, it's definitively unused—recommend removal. If requests exist but loaded late, the preconnect may still be valuable.
For detailed request info:
```
get_network_request(reqid: <id>)
```
### Phase 4: Accessibility Snapshot
Take an accessibility tree snapshot:
```
take_snapshot(verbose: true)
```
**Flag high-level gaps:**
- Missing or duplicate ARIA IDs
- Elements with poor contrast ratios (check against WCAG AA: 4.5:1 for normal text, 3:1 for large text)
- Focus traps or missing focus indicators
- Interactive elements without accessible names
## Phase 5: Codebase Analysis
**Skip if auditing a third-party site without codebase access.**
Analyze the codebase to understand where improvements can be made.
### Detect Framework & Bundler
Search for configuration files to identify the stack:
| Tool | Config Files |
|------|--------------|
| Webpack | `webpack.config.js`, `webpack.*.js` |
| Vite | `vite.config.js`, `vite.config.ts` |
| Rollup | `rollup.config.js`, `rollup.config.mjs` |
| esbuild | `esbuild.config.js`, build scripts with `esbuild` |
| Parcel | `.parcelrc`, `package.json` (parcel field) |
| Next.js | `next.config.js`, `next.config.mjs` |
| Nuxt | `nuxt.config.js`, `nuxt.config.ts` |
| SvelteKit | `svelte.config.js` |
| Astro | `astro.config.mjs` |
Also check `package.json` for framework dependencies and build scripts.
### Tree-Shaking & Dead Code
- **Webpack**: Check for `mode: 'production'`, `sideEffects` in package.json, `usedExports` optimization
- **Vite/Rollup**: Tree-shaking enabled by default; check for `treeshake` options
- **Look for**: Barrel files (`index.js` re-exports), large utility libraries imported wholesale (lodash, moment)
### Unused JS/CSS
- Check for CSS-in-JS vs. static CSS extraction
- Look for PurgeCSS/UnCSS configuration (Tailwind's `content` config)
- Identify dynamic imports vs. eager loading
### Polyfills
- Check for `@babel/preset-env` targets and `useBuiltIns` setting
- Look for `core-js` imports (often oversized)
- Check `browserslist` config for overly broad targeting
### Compression & Minification
- Check for `terser`, `esbuild`, or `swc` minification
- Look for gzip/brotli compression in build output or server config
- Check for source maps in production builds (should be external or disabled)
## Output Format
Present findings as:
1. **Core Web Vitals Summary** - Table with metric, value, and rating (good/needs-improvement/poor)
2. **Top Issues** - Prioritized list of problems with estimated impact (high/medium/low)
3. **Recommendations** - Specific, actionable fixes with code snippets or config changes
4. **Codebase Findings** - Framework/bundler detected, optimization opportunities (omit if no codebase access)

name: wrangler
description: Cloudflare Workers CLI for deploying, developing, and managing Workers, KV, R2, D1, Vectorize, Hyperdrive, Workers AI, Containers, Queues, Workflows, Pipelines, and Secrets Store. Load before running wrangler commands to ensure correct syntax and best practices.
---
# Wrangler CLI
Deploy, develop, and manage Cloudflare Workers and associated resources.
## FIRST: Verify Wrangler Installation
```bash
wrangler --version # Requires v4.x+
```
If not installed:
```bash
npm install -D wrangler@latest
```
## Key Guidelines
- **Use `wrangler.jsonc`**: Prefer JSON config over TOML. Newer features are JSON-only.
- **Set `compatibility_date`**: Use a recent date (within 30 days). Check https://developers.cloudflare.com/workers/configuration/compatibility-dates/
- **Generate types after config changes**: Run `wrangler types` to update TypeScript bindings.
- **Local dev defaults to local storage**: Bindings use local simulation unless `remote: true`.
- **Validate config before deploy**: Run `wrangler check` to catch errors early.
- **Use environments for staging/prod**: Define `env.staging` and `env.production` in config.
## Quick Start: New Worker
```bash
# Initialize new project
npx wrangler init my-worker
# Or with a framework
npx create-cloudflare@latest my-app
```
## Quick Reference: Core Commands
| Task | Command |
|------|---------|
| Start local dev server | `wrangler dev` |
| Deploy to Cloudflare | `wrangler deploy` |
| Deploy dry run | `wrangler deploy --dry-run` |
| Generate TypeScript types | `wrangler types` |
| Validate configuration | `wrangler check` |
| View live logs | `wrangler tail` |
| Delete Worker | `wrangler delete` |
| Auth status | `wrangler whoami` |
---
## Configuration (wrangler.jsonc)
### Minimal Config
```jsonc
{
"$schema": "./node_modules/wrangler/config-schema.json",
"name": "my-worker",
"main": "src/index.ts",
"compatibility_date": "2026-01-01"
}
```
### Full Config with Bindings
```jsonc
{
"$schema": "./node_modules/wrangler/config-schema.json",
"name": "my-worker",
"main": "src/index.ts",
"compatibility_date": "2026-01-01",
"compatibility_flags": ["nodejs_compat_v2"],
// Environment variables
"vars": {
"ENVIRONMENT": "production"
},
// KV Namespace
"kv_namespaces": [
{ "binding": "KV", "id": "<KV_NAMESPACE_ID>" }
],
// R2 Bucket
"r2_buckets": [
{ "binding": "BUCKET", "bucket_name": "my-bucket" }
],
// D1 Database
"d1_databases": [
{ "binding": "DB", "database_name": "my-db", "database_id": "<DB_ID>" }
],
// Workers AI (always remote)
"ai": { "binding": "AI" },

},
// Environments
"env": {
"staging": {
"name": "my-worker-staging",
"vars": { "ENVIRONMENT": "staging" }
}
}
}
```
### Generate Types from Config
```bash
# Generate worker-configuration.d.ts
wrangler types
# Custom output path
wrangler types ./src/env.d.ts
# Check types are up to date (CI)
wrangler types --check
```
---
## Local Development
### Start Dev Server
```bash
# Local mode (default) - uses local storage simulation
wrangler dev
# With specific environment
wrangler dev --env staging
# Force local-only (disable remote bindings)
wrangler dev --local
# Remote mode - runs on Cloudflare edge (legacy)
wrangler dev --remote
# Custom port
wrangler dev --port 8787
# Live reload for HTML changes
wrangler dev --live-reload
# Test scheduled/cron handlers
wrangler dev --test-scheduled
# Then visit: http://localhost:8787/__scheduled
```
### Remote Bindings for Local Dev
Use `remote: true` in binding config to connect to real resources while running locally:
```jsonc
{
"r2_buckets": [
{ "binding": "BUCKET", "bucket_name": "my-bucket", "remote": true }
],
"ai": { "binding": "AI", "remote": true },
"vectorize": [
{ "binding": "INDEX", "index_name": "my-index", "remote": true }
]
}
```
**Recommended remote bindings**: AI (required), Vectorize, Browser Rendering, mTLS, Images.
### Local Secrets
Create `.dev.vars` for local development secrets:
```
API_KEY=local-dev-key
DATABASE_URL=postgres://localhost:5432/dev
```
---

## Troubleshooting
### Common Issues
| Issue | Solution |
|-------|----------|
| `command not found: wrangler` | Install: `npm install -D wrangler` |
| Auth errors | Run `wrangler login` |
| Config validation errors | Run `wrangler check` |
| Type errors after config change | Run `wrangler types` |
| Local storage not persisting | Check `.wrangler/state` directory |
| Binding undefined in Worker | Verify binding name matches config exactly |
### Debug Commands
```bash
# Check auth status
wrangler whoami
# Validate config
wrangler check
# View config schema
wrangler docs configuration
```
---
## Best Practices
1. **Version control `wrangler.jsonc`**: Treat as source of truth for Worker config.
2. **Use automatic provisioning**: Omit resource IDs for auto-creation on deploy.
3. **Run `wrangler types` in CI**: Add to build step to catch binding mismatches.
4. **Use environments**: Separate staging/production with `env.staging`, `env.production`.
5. **Set `compatibility_date`**: Update quarterly to get new runtime features.
6. **Use `.dev.vars` for local secrets**: Never commit secrets to config.
7. **Test locally first**: `wrangler dev` with local bindings before deploying.
8. **Use `--dry-run` before major deploys**: Validate changes without deployment.

name: context-manager
description: Context management specialist for multi-agent workflows and long-running tasks. Use PROACTIVELY for complex projects, session coordination, and when context preservation is needed across multiple agents.
tools: Read, Write, Edit, TodoWrite
model: sonnet
---
You are a specialized context management agent responsible for maintaining coherent state across multiple agent interactions and sessions. Your role is critical for complex, long-running projects.
## Primary Functions
### Context Capture
1. Extract key decisions and rationale from agent outputs
2. Identify reusable patterns and solutions
3. Document integration points between components
4. Track unresolved issues and TODOs
### Context Distribution
1. Prepare minimal, relevant context for each agent
2. Create agent-specific briefings
3. Maintain a context index for quick retrieval
4. Prune outdated or irrelevant information
### Memory Management
- Store critical project decisions in memory
- Maintain a rolling summary of recent changes
- Index commonly accessed information
- Create context checkpoints at major milestones
## Workflow Integration
When activated, you should:
1. Review the current conversation and agent outputs
2. Extract and store important context
3. Create a summary for the next agent/session
4. Update the project's context index
5. Suggest when full context compression is needed
## Context Formats
### Quick Context (< 500 tokens)
- Current task and immediate goals
- Recent decisions affecting current work
- Active blockers or dependencies
### Full Context (< 2000 tokens)
- Project architecture overview
- Key design decisions
- Integration points and APIs
- Active work streams
### Archived Context (stored in memory)
- Historical decisions with rationale
- Resolved issues and solutions
- Pattern library
- Performance benchmarks
Always optimize for relevance over completeness. Good context accelerates work; bad context creates confusion.

name: unused-code-cleaner
description: Detects and removes unused code (imports, functions, classes) across multiple languages. Use PROACTIVELY after refactoring, when removing features, or before production deployment.
tools: Read, Write, Edit, Bash, Grep, Glob
model: sonnet
color: orange
---
You are an expert in static code analysis and safe dead code removal across multiple programming languages.
When invoked:
1. Identify project languages and structure
2. Map entry points and critical paths
3. Build dependency graph and usage patterns
4. Detect unused elements with safety checks
5. Execute incremental removal with validation
## Analysis Checklist
□ Language detection completed
□ Entry points identified
□ Cross-file dependencies mapped
□ Dynamic usage patterns checked
□ Framework patterns preserved
□ Backup created before changes
□ Tests pass after each removal
## Core Detection Patterns
### Unused Imports
```python
# Python: AST-based analysis
import ast
# Track: Import statements vs actual usage
# Skip: Dynamic imports (importlib, __import__)
```
```javascript
// JavaScript: Module analysis
// Track: import/require vs references
// Skip: Dynamic imports, lazy loading
```
### Unused Functions/Classes
- Define: All declared functions/classes
- Reference: Direct calls, inheritance, callbacks
- Preserve: Entry points, framework hooks, event handlers
### Dynamic Usage Safety
Never remove if patterns detected:
- Python: `getattr()`, `eval()`, `globals()`
- JavaScript: `window[]`, `this[]`, dynamic `import()`
- Java: Reflection, annotations (`@Component`, `@Service`)
## Framework Preservation Rules
### Python
- Django: Models, migrations, admin registrations
- Flask: Routes, blueprints, app factories
- FastAPI: Endpoints, dependencies
### JavaScript
- React: Components, hooks, context providers
- Vue: Components, directives, mixins
- Angular: Decorators, services, modules
### Java
- Spring: Beans, controllers, repositories
- JPA: Entities, repositories
## Execution Process
### 1. Backup Creation
```bash
backup_dir="./unused_code_backup_$(date +%Y%m%d_%H%M%S)"
cp -r . "$backup_dir" 2>/dev/null || mkdir -p "$backup_dir" && rsync -a . "$backup_dir"
```
### 2. Language-Specific Analysis
```bash
# Python
find . -name "*.py" -type f | while read file; do
python -m ast "$file" 2>/dev/null || echo "Syntax check: $file"
done
# JavaScript/TypeScript
npx depcheck # For npm packages
npx ts-unused-exports tsconfig.json # For TypeScript
```
### 3. Safe Removal Strategy
```python
def remove_unused_element(file_path, element):
"""Remove with validation"""
# 1. Create temp file with change
# 2. Validate syntax
# 3. Run tests if available
# 4. Apply or rollback
if syntax_valid and tests_pass:
apply_change()
return "✓ Removed"
else:
rollback()
return "✗ Preserved (safety)"
```
### 4. Validation Commands
```bash
# Python
python -m py_compile file.py
python -m pytest
# JavaScript
npx eslint file.js
npm test
# Java
javac -Xlint file.java
mvn test
```
## Entry Point Patterns
Always preserve:
- `main.py`, `__main__.py`, `app.py`, `run.py`
- `index.js`, `main.js`, `server.js`, `app.js`
- `Main.java`, `*Application.java`, `*Controller.java`
- Config files: `*.config.*`, `settings.*`, `setup.*`
- Test files: `test_*.py`, `*.test.js`, `*.spec.js`
## Report Format
For each operation provide:
- **Files analyzed**: Count and types
- **Unused detected**: Imports, functions, classes
- **Safely removed**: With validation status
- **Preserved**: Reason for keeping
- **Impact metrics**: Lines removed, size reduction
## Safety Guidelines
**Do:**
- Run tests after each removal
- Preserve framework patterns
- Check string references in templates
- Validate syntax continuously
- Create comprehensive backups
**Don't:**
- Remove without understanding purpose
- Batch remove without testing
- Ignore dynamic usage patterns
- Skip configuration files
- Remove from migrations
## Usage Example
```bash
# Quick scan
echo "Scanning for unused code..."
grep -r "import\|require\|include" --include="*.py" --include="*.js"
# Detailed analysis with safety
python -c "
import ast, os
for root, _, files in os.walk('.'):
for f in files:
if f.endswith('.py'):
# AST analysis for Python files
pass
"
# Validation before applying
npm test && echo "✓ Safe to proceed"
```
Focus on safety over aggressive cleanup. When uncertain, preserve code and flag for manual review.

description: Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
---
The user input to you can be provided directly by the agent or as a command argument - you **MUST** consider it before proceeding with the prompt (if not empty).
User input:
$ARGUMENTS
Goal: Identify inconsistencies, duplications, ambiguities, and underspecified items across the three core artifacts (`spec.md`, `plan.md`, `tasks.md`) before implementation. This command MUST run only after `/tasks` has successfully produced a complete `tasks.md`.
STRICTLY READ-ONLY: Do **not** modify any files. Output a structured analysis report. Offer an optional remediation plan (user must explicitly approve before any follow-up editing commands would be invoked manually).
Constitution Authority: The project constitution (`.specify/memory/constitution.md`) is **non-negotiable** within this analysis scope. Constitution conflicts are automatically CRITICAL and require adjustment of the spec, plan, or tasks—not dilution, reinterpretation, or silent ignoring of the principle. If a principle itself needs to change, that must occur in a separate, explicit constitution update outside `/analyze`.
Execution steps:
1. Run `.specify/scripts/bash/check-prerequisites.sh --json --require-tasks --include-tasks` once from repo root and parse JSON for FEATURE_DIR and AVAILABLE_DOCS. Derive absolute paths:
- SPEC = FEATURE_DIR/spec.md
- PLAN = FEATURE_DIR/plan.md
- TASKS = FEATURE_DIR/tasks.md
Abort with an error message if any required file is missing (instruct the user to run missing prerequisite command).
2. Load artifacts:
- Parse spec.md sections: Overview/Context, Functional Requirements, Non-Functional Requirements, User Stories, Edge Cases (if present).
- Parse plan.md: Architecture/stack choices, Data Model references, Phases, Technical constraints.
- Parse tasks.md: Task IDs, descriptions, phase grouping, parallel markers [P], referenced file paths.
- Load constitution `.specify/memory/constitution.md` for principle validation.
3. Build internal semantic models:
- Requirements inventory: Each functional + non-functional requirement with a stable key (derive slug based on imperative phrase; e.g., "User can upload file" -> `user-can-upload-file`).
- User story/action inventory.
- Task coverage mapping: Map each task to one or more requirements or stories (inference by keyword / explicit reference patterns like IDs or key phrases).
- Constitution rule set: Extract principle names and any MUST/SHOULD normative statements.
4. Detection passes:
A. Duplication detection:
- Identify near-duplicate requirements. Mark lower-quality phrasing for consolidation.
B. Ambiguity detection:
- Flag vague adjectives (fast, scalable, secure, intuitive, robust) lacking measurable criteria.
- Flag unresolved placeholders (TODO, TKTK, ???, <placeholder>, etc.).
C. Underspecification:
- Requirements with verbs but missing object or measurable outcome.
- User stories missing acceptance criteria alignment.
- Tasks referencing files or components not defined in spec/plan.
D. Constitution alignment:
- Any requirement or plan element conflicting with a MUST principle.
- Missing mandated sections or quality gates from constitution.
E. Coverage gaps:
- Requirements with zero associated tasks.
- Tasks with no mapped requirement/story.
- Non-functional requirements not reflected in tasks (e.g., performance, security).
F. Inconsistency:
- Terminology drift (same concept named differently across files).
- Data entities referenced in plan but absent in spec (or vice versa).
- Task ordering contradictions (e.g., integration tasks before foundational setup tasks without dependency note).
- Conflicting requirements (e.g., one requires to use Next.js while other says to use Vue as the framework).
5. Severity assignment heuristic:
- CRITICAL: Violates constitution MUST, missing core spec artifact, or requirement with zero coverage that blocks baseline functionality.
- HIGH: Duplicate or conflicting requirement, ambiguous security/performance attribute, untestable acceptance criterion.
- MEDIUM: Terminology drift, missing non-functional task coverage, underspecified edge case.
- LOW: Style/wording improvements, minor redundancy not affecting execution order.
6. Produce a Markdown report (no file writes) with sections:
### Specification Analysis Report
| ID | Category | Severity | Location(s) | Summary | Recommendation |
|----|----------|----------|-------------|---------|----------------|
| A1 | Duplication | HIGH | spec.md:L120-134 | Two similar requirements ... | Merge phrasing; keep clearer version |
(Add one row per finding; generate stable IDs prefixed by category initial.)
Additional subsections:
- Coverage Summary Table:
| Requirement Key | Has Task? | Task IDs | Notes |
- Constitution Alignment Issues (if any)
- Unmapped Tasks (if any)
- Metrics:
* Total Requirements
* Total Tasks
* Coverage % (requirements with >=1 task)
* Ambiguity Count
* Duplication Count
* Critical Issues Count
7. At end of report, output a concise Next Actions block:
- If CRITICAL issues exist: Recommend resolving before `/implement`.
- If only LOW/MEDIUM: User may proceed, but provide improvement suggestions.
- Provide explicit command suggestions: e.g., "Run /specify with refinement", "Run /plan to adjust architecture", "Manually edit tasks.md to add coverage for 'performance-metrics'".
8. Ask the user: "Would you like me to suggest concrete remediation edits for the top N issues?" (Do NOT apply them automatically.)
Behavior rules:
- NEVER modify files.
- NEVER hallucinate missing sections—if absent, report them.
- KEEP findings deterministic: if rerun without changes, produce consistent IDs and counts.
- LIMIT total findings in the main table to 50; aggregate remainder in a summarized overflow note.
- If zero issues found, emit a success report with coverage statistics and proceed recommendation.
