| description | Validate Claude Code skills against best practices. Use when checking skill quality, running validation, or creating improvement issues. |
Framework for validating Claude Code skills against best practices. This skill provides checklists and templates used by validation commands.
| Resource | Purpose |
|---|---|
| checklists/frontmatter.md | Name, description, required fields |
| checklists/structure.md | Token budget, progressive disclosure |
| checklists/quality.md | Content quality checks |
| checklists/8-pillars.md | 8+1 Pillar coverage for lang/convert skills |
| templates/issue-templates.md | GitHub issue body templates |
| Level | Scope | Command |
|---|---|---|
| Quick | Naming, frontmatter, SKILL.md exists | just validate-skill <path> |
| Standard | + Token budget, structure, quality | /refine-skill --check-only |
| Deep | + 8 Pillars, meta-skill compliance | /validate-lang-conversion-skill |
just validate-skill components/skills/my-skill
Checks:
/refine-skill components/skills/my-skill --check-only
Adds:
/validate-lang-conversion-skill convert-python-rust
# Or for pillar coverage only:
just validate-pillars lang-rust-dev
Adds:
| Severity | Definition | Action |
|---|---|---|
| Critical | Blocks functionality, must fix before use | Create bug issue |
| Warning | Should fix, impacts quality | Create enhancement issue |
| Suggestion | Nice to have, improves experience | Create docs issue |
| Check | Critical | Warning | Pass |
|---|---|---|---|

Developing custom GitHub Actions (JavaScript, TypeScript, Docker, Composite). Use this skill when the user asks to 'create a GitHub Action', 'build a custom action', 'publish action to marketplace', 'write action.yml', or 'develop reusable action'.
Use when creating new skills, editing existing skills, initializing skill structure, packaging skills for distribution, or verifying skills work before deployment. This skill applies TDD methodology to documentation.
Identify skill coverage gaps and improvement opportunities. Use when analyzing missing skills for a task, creating skill gap issues, evaluating skill effectiveness, or refining skill progressive disclosure.
Create, test, and maintain Homebrew formulas. Use when adding packages to a Homebrew tap, debugging formula issues, running brew audit/test, or automating version updates with livecheck.
