tasks

Break down the plan into executable tasks.

This is the third step in the Spec-Driven Development lifecycle.

Given the context provided as an argument, do this:

1. Run scripts/check-task-prerequisites.sh --json from repo root and parse FEATURE_DIR and AVAILABLE_DOCS list. All paths must be absolute.

2. Load and analyze available design documents:

   • Always read plan.md for tech stack and libraries
   • IF EXISTS: Read data-model.md for entities
   • IF EXISTS: Read contracts/ for API endpoints
   • IF EXISTS: Read research.md for technical decisions
   • IF EXISTS: Read quickstart.md for test scenarios

   Note: Not all projects have all documents. For example:

   • CLI tools might not have contracts/
   • Simple libraries might not need data-model.md
   • Generate tasks based on what's available

3. Generate tasks following the template:

   • Use /templates/tasks-template.md as the base
   • Replace example tasks with actual tasks based on:
     • Setup tasks: Project init, dependencies, linting
     • Test tasks [P]: One per contract, one per integration scenario
     • Core tasks: One per entity, service, CLI command, endpoint
     • Integration tasks: DB connections, middleware, logging
     • Polish tasks [P]: Unit tests, performance, docs

4. Task generation rules:

   • Each contract file → contract test task marked [P]
   • Each entity in data-model → model creation task marked [P]
   • Each endpoint → implementation task (not parallel if shared files)
   • Each user story → integration test marked [P]
   • Different files = can be parallel [P]
   • Same file = sequential (no [P])

5. Order tasks by dependencies:

   • Setup before everything
   • Tests before implementation (TDD)
   • Models before services
   • Services before endpoints
   • Core before integration
   • Everything before polish

6. Include parallel execution examples:

   • Group [P] tasks that can run together
   • Show actual Task agent commands

7. Create FEATURE_DIR/tasks.md with:

   • Correct feature name from implementation plan
   • Numbered tasks (T001, T002, etc.)
   • Clear file paths for each task
   • Dependency notes
   • Parallel execution guidance

Context for task generation: $ARGUMENTS

The tasks.md should be immediately executable - each task must be specific enough that an LLM can complete it without additional context.
