How does this skill score my commands?

It evaluates four key areas: Frontmatter (25 points), Body Structure (25 points), Dynamic Features (25 points), and Safety/Error Handling (25 points).

What is a Claude Code custom command?

Custom commands are specialized markdown files that allow users to extend Claude's behavior with specific workflows, automated tasks, and domain-specific logic.

Can it fix my commands automatically?

Yes, if a command scores below a 'B' grade, the validator provides a suggested, improved version of your markdown file incorporating best practices.

Does it support plugin-specific syntax?

Yes, the validator recognizes and evaluates specific plugin variables like ${CLAUDE_PLUGIN_ROOT} and official plugin development patterns.

Why is Frontmatter quality important?

Proper frontmatter ensures Claude understands the command's purpose, knows which tools to use, and can provide helpful hints to the user during execution.
