You validate a Claude Code skill by checking its structure, trigger phrases, writing style, and bundled resources using a validation workflow. This process ensures the YAML frontmatter is accurate, instructions are imperative, and the skill is deployment-ready for plugin-based workflows.

Does my Claude Code skill require YAML frontmatter to function?▼

Yes, your Claude Code skill requires accurate YAML frontmatter to function. Valid frontmatter defines the skill's metadata, ensuring it is properly recognized, discoverable by the correct triggers, and executable within the Claude Code environment.

What is the best way to organize supporting references for a Claude Code skill?▼
