Feature Lifecycle Skill

Phase-gated feature workflow: DESIGN > PLAN > IMPLEMENT > VALIDATE > RELEASE. Each phase must pass its gate before the next begins.

Phase Routing

Determine which phase to execute based on feature state:

1. If .feature/ exists, check current phase:

   python3 ~/.claude/scripts/feature-state.py status
   

   Route to the phase indicated by the state machine.

2. If no feature state exists, determine entry point from user intent:

   • "design", "think through", "explore approaches" -> DESIGN
   • "plan", "break down", "create tasks" -> PLAN (requires completed design)
   • "implement", "execute plan", "start building" -> IMPLEMENT (requires completed plan)
   • "validate", "quality gates", "check feature" -> VALIDATE (requires completed implementation)
