Validates every SKILL.md and command file in this repository against the Agent Skills specification and the repo's own conventions, reporting structural errors before they reach CI. Use when verifying skills are well-formed — before a release, after adding or editing a skill, or when a skill-validation gate fails.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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.

How to install

The exact contents, by fingerprint
mdr add ivuorinen/skills/validate-skills@sha256:5fc1160b9dadeb19

The line at the top of this page pins the label git:20261027.410058f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
