If you're building skills for Claude Code, this is your design system. It handles the full lifecycle: scaffolding new skills from scratch, auditing existing ones for activation problems, and encoding real domain expertise using progressive disclosure patterns. The three-layer architecture (lightweight metadata, lean SKILL.md under 500 lines, on-demand references) is the core philosophy here. Most useful when you're debugging why a skill won't activate, tightening descriptions to reduce false positives, or refactoring bloated skills that dump everything into context at once. Pairs naturally with skill-grader for feedback loops and skill-creator for implementation. Think of it as the meta-tool that teaches you to write skills that actually trigger when they should and stay quiet when they shouldn't.
