Orchestrate KB development workflow from request to completion.Coordinates skills in sequence: kb → plan → test → validate → complete → reflect → inbox.WORKFLOW:1. LOOKUP - /pmc:kb (check existing PRDs, patterns, code maps)2. PLAN - /pmc:plan + /pmc:plan-validation + /pmc:lint-kb3. IMPLEMENT - /pmc:test (TDD cycle: RED → GREEN → REFACTOR)4. VALIDATE - /pmc:validate + /pmc:ticket-status5. COMPLETE - /pmc:complete (write 5-final.md, commit)6. REFLECT - /pmc:reflect + /pmc:lint-kb7. INBOX - /pmc:inbox (process pending items)Use when:- User says "implement", "build", "develop", "work on"- Starting new feature or phase work- Need guided workflow from start to finish- User says "dev workflow", "full cycle"
