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.
