# Skill Check

> Evaluate a SKILL.md file using three-layer linting: schema validation, 17 skill-authoring patterns, and optional substance review (--deep). Use when reviewing skill quality, checking pattern coverage, testing activation metadata, or assessing a skill before sharing. Add --deep for qualitative substance review. Do NOT use for prompt-level analysis (use prompt:skill-checker instead) or for enhancing/rewriting skills (use skill:enhance instead).
