Execute the implementation plan by processing and executing all tasks defined in tasks.md

User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Outline

1. Run .specify/scripts/bash/check-prerequisites.sh --json --require-tasks --include-tasks from repo root and parse FEATURE_DIR and AVAILABLE_DOCS list. All paths must be absolute.

2. Check checklists status (if FEATURE_DIR/checklists/ exists):

   • Scan all checklist files in the checklists/ directory

   • For each checklist, count:

     • Total items: All lines matching - [ ] or - [X] or - [x]
     • Completed items: Lines matching - [X] or - [x]
     • Incomplete items: Lines matching - [ ]

   • Create a status table:

     | Checklist | Total | Completed | Incomplete | Status |
     |-----------|-------|-----------|------------|--------|
     | ux.md     | 12    | 12        | 0          | ✓ PASS |
     | test.md   | 8     | 5         | 3          | ✗ FAIL |
     | security.md | 6   | 6         | 0          | ✓ PASS |
     

   • Calculate overall status:

     • PASS: All checklists have 0 incomplete items
     • FAIL: One or more checklists have incomplete items

   • If any checklist is incomplete:

     • Display the table with incomplete item counts
     • STOP and ask: "Some checklists are incomplete. Do you want to proceed with implementation anyway? (yes/no)"
     • Wait for user response before continuing
     • If user says "no" or "wait" or "stop", halt execution
     • If user says "yes" or "proceed" or "continue", proceed to step 3

   • If all checklists are complete:

     • Display the table showing all checklists passed
     • Automatically proceed to step 3

3. Load and analyze the implementation context:

   • REQUIRED: Read tasks.md for the complete task list and execution plan
   • REQUIRED: Read plan.md for tech stack, architecture, and file structure
   • IF EXISTS: Read data-model.md for entities and relationships
   • IF EXISTS: Read contracts/ for API specifications and test requirements
   • IF EXISTS: Read research.md for technical decisions and constraints
   • IF EXISTS: Read quickstart.md for integration scenarios

4. Parse tasks.md structure and extract:

   • Task phases: Setup, Tests, Core, Integration, Polish
   • Task dependencies: Sequential vs parallel execution rules
   • Task details: ID, description, file paths, parallel markers [P]
   • Execution flow: Order and dependency requirements

5. Execute implementation following the task plan:

   • Phase-by-phase execution: Complete each phase before moving to the next
   • Respect dependencies: Run sequential tasks in order, parallel tasks [P] can run together
   • Follow TDD approach: Execute test tasks before their corresponding implementation tasks
   • File-based coordination: Tasks affecting the same files must run sequentially
   • Validation checkpoints: Verify each phase completion before proceeding

6. Implementation execution rules:

   • Setup first: Initialize project structure, dependencies, configuration
   • Tests before code: If you need to write tests for contracts, entities, and integration scenarios
   • Core development: Implement models, services, CLI commands, endpoints
   • Integration work: Database connections, middleware, logging, external services
   • Polish and validation: Unit tests, performance optimization, documentation

7. Progress tracking and error handling:

   • Report progress after each completed task
   • Halt execution if any non-parallel task fails
   • For parallel tasks [P], continue with successful tasks, report failed ones
   • Provide clear error messages with context for debugging
   • Suggest next steps if implementation cannot proceed
   • IMPORTANT For completed tasks, make sure to mark the task off as [X] in the tasks file.

8. Completion validation:

   • Verify all required tasks are completed
   • Check that implemented features match the original specification
   • Validate that tests pass and coverage meets requirements
   • Confirm the implementation follows the technical plan
   • Report final status with summary of completed work

Note: This command assumes a complete task breakdown exists in tasks.md. If tasks are incomplete or missing, suggest running /tasks first to regenerate the task list.
