Can this skill fix errors automatically?

Yes, it has auto-fix capabilities for common issues like script permissions (chmod +x), JSON formatting via jq, and syncing version numbers across metadata files.

What specifically does the Plugin Validator check?

It verifies required files (README, LICENSE, plugin.json), validates JSON schemas, checks markdown frontmatter, scans for hardcoded secrets, and ensures script permissions are correct.

How do I start a validation check?

You can trigger the skill by using keywords such as 'validate plugin', 'check plugin', or 'verify plugin' while Claude is focused on your plugin directory.

Is it compatible with GitHub Actions?

Yes, the validation logic is designed to match standard CI/CD workflows, allowing you to catch errors locally before they fail in a repository pipeline.
