SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pyyaml, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Valide la conformite structurelle d'un SKILL.md (standards Anthropic, score /50, deterministe). Utiliser quand l'utilisateur dit "verifie ce skill" ou "check skill". Pour l'evaluation semantique, utiliser /skill-review.

Core Features & Use Cases

  • Validates the presence and correctness of frontmatter (name, description, etc.) and the body structure per Anthropic S01-S15.
  • Produces a deterministic score out of 50, plus an empirical SkillsBench rubric (S16-S20) for a total of 65 points, with a detailed report.
  • Supports batch validation in workspace workflows and integrates with /skill-review for semantic evaluation.

Quick Start

Run /skill-conformity-checker <path-to-SKILL.md> to audit a skill's structure.

Frequently Asked Questions about skill-conformity-checker

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I validate a SKILL.md file against Anthropic structural standards?

The checker validates frontmatter correctness, body structure, and resource references per Anthropic S01-S15 criteria, generating a formal report with a deterministic score out of 50.

What is a deterministic skill validation score?

A deterministic skill validation score is a reproducible 50-point rating generated by applying a fixed rubric defined in references/criteres-conformite.md to a SKILL.md file's structure and frontmatter.

Can I batch validate multiple Claude skills in a repository?

Yes, you can batch validate multiple Claude skills in a repository using workspace workflows to apply structural conformance checks across all SKILL.md files and generate a consolidated formal report.

Does the validator check semantic quality or only structural conformance?

The validator checks only structural conformance and frontmatter correctness, producing a deterministic score. For semantic evaluation, you must integrate it with the /skill-review command.

Do I need pyyaml installed to run the skill conformance checker?

Yes, you need pyyaml installed, as the skill depends on it to parse and validate the frontmatter YAML structure within your SKILL.md files accurately.

What is the difference between the 50-point score and the 65-point total score?

The 50-point score enforces deterministic structural conformance per S01-S15, while the 65-point total adds an empirical SkillsBench rubric (S16-S20) to evaluate additional skill quality dimensions.
