What is a Claude Code Skill?

A Claude Code Skill is a specialized capability that enhances Claude's behavior during specific tasks by providing domain-specific guidance, implementation patterns, and best practices.

Why isn't my Claude Code skill being invoked?

Common issues include vague descriptions or missing trigger keywords. This validator helps you audit your YAML frontmatter to ensure Claude knows exactly when to use your skill.

Does this tool help with cross-model compatibility?

Yes, it provides a testing workflow to verify that your skill works consistently across Claude Haiku, Sonnet, and Opus models.

When should I split a skill into multiple files?

The Skill Quality Validator recommends splitting a skill into a directory structure (with EXAMPLES.md, scripts, etc.) if the primary SKILL.md exceeds 500 lines.
