Where should I store my skills for validation?

Skill Check scans both personal skill directories (~/.claude/skills/) and project-specific directories (.claude/skills/).

Can it automatically fix issues?

Yes, the skill can optionally apply suggested fixes to your SKILL.md and supporting files after your approval.

What does Skill Check actually validate?

It checks YAML frontmatter syntax, naming conventions, description clarity, file structure, and adherence to the Agent Skills best practices.

Why is description quality important for skills?

Claude uses these descriptions to decide when to trigger a skill; well-formatted descriptions with clear keywords improve discoverability and performance.
