Build, evaluate, improve, and analyze Claude Code skills. Encodes skill-design expertise — description optimization, progressive disclosure via _references/, knowledge-delta scoring, archetype selection, anti-pattern detection. ANALYZE mode reads ~/.claude/skill-feedback.jsonl (populated by /rem-feedback), aggregates by skill + mistake_type, and proposes targeted edits — description triggers for misrouted flags, new anti-patterns for missed, severity calibration for over-flagged, Step-0-context for context-ignored, freshness stamps for stale. IMPROVE mode consumes that analysis and applies edits, marking entries addressed. Use when the user says "create skill", "new skill", "evaluate skill", "audit skill", "improve skill", "refactor skill", "skill builder", "meta-skill", "analyze skill", "aggregate feedback", "why is rem-X misfiring", "skill report card", "skill health", "skill won''t load", "skill not triggering", "skill not firing", "diagnose skill", "skill doctor", "why isn''t my skill loading".
