# Validate Skills ## Steps 1. Run the validator across all skills — public and internal: ```bash uv run scripts/validate-skill.py uv run scripts/validate-skill.py .claude/skills/*/SKILL.md ``` To validate only public skills: ```bash uv run scripts/validate-skill.py ``` To validate only internal skills: ```bash uv run scripts/validate-skill.py .claude/skills/*/SKILL.md ``` 2. If any **errors** are reported, fix them before proceeding. Errors are blocking. 3. **Warnings** should be reviewed; fix if the skill is being released. 4. Run the version sync check: ```bash uv run scripts/check-version-sync.py ``` 5. If all checks pass, skills are release-ready. ## What is checked | Check | Level | |-------|-------| | Frontmatter present | Error | | `name` field present | Error | | `description` field present | Error | | Description contains "Use when" trigger clause | Error | | Description ≤ 1024 chars | Error | | Skill name matches directory name | Error | | Header level progression (no skipping levels) | Error | | Description with `': '` must be single-quoted | Error | | Legacy output paths (`./codereview.md` etc.) | Warning | | Body exceeds 500 lines | Warning |
