Can I validate multiple plugins at once?

Yes, the skill supports a '--all' flag which allows you to scan and validate every plugin within your repository simultaneously.

How do I run the validation for a specific plugin?

You can invoke the skill directly in Claude Code using the command /validate-plugin followed by the name of the plugin directory.

What specifically does Plugin Validator check for?

It verifies required file existence, JSON syntax in manifests, proper YAML frontmatter in skill/agent files, and ensures compliance with the latest Claude Code architectural standards.

Why does the validator flag my 'commands' directory?

As of Claude Code version 2.1.3, commands have been merged into skills. The validator identifies the old directory structure as deprecated to ensure your plugin remains modern.

Does this skill perform functional testing of the code?

No, this skill focuses on structural and manifest validation. It ensures your plugin can be correctly loaded and indexed by the marketplace and the Claude environment.
