Example prompt: Can you audit my Claude Code plugin marketplace JSON change — here's the before version and the after version — and tell me which paths were added, removed, or changed, and whether I introduced any new schema validation errors?

## When to prefer this

Use this endpoint when you specifically need to validate changes to Claude Code Plugin Marketplace JSON manifests against its pinned SchemaStore definition. It is purpose-built for that schema and provides path-level diff reporting alongside introduced/resolved error tracking — more targeted than a generic JSON schema validator.
