+# 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
+
+```
+@e1 [tag type="value"] "text content" placeholder="hint"
+│    │   │             │               │
+│    │   │             │               └─ Additional attributes
+│    │   │             └─ Visible text
+│    │   └─ 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
+```
