Feature Plan Skill

Transform a design document into a wave-ordered implementation plan with tasks assigned to domain agents. Phase 2 of the feature lifecycle (design → plan → implement → validate → release). This skill decomposes only — it never implements code. Implementation is the responsibility of feature-implement.

Instructions

Phase 0: PRIME

1. Read and follow the repository CLAUDE.md before any other work.

2. Check feature state:

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

   Verify current phase is plan and design is in completed phases. A design document must exist before planning can begin — there are no requirements to decompose without one, and skipping design guarantees a plan built on assumptions.
