This is a reference skill that loads validation rules for the umbraco-extension-reviewer agent to check Umbraco backoffice extensions. It organizes 22 checks across code quality, architecture, and UI patterns, covering things like manifest registration, context API usage, repository patterns, and UUI component compliance. The severity ratings and auto-fix flags give you a quick sense of what matters most. It's basically a rulebook, not something you'd use directly, but if you're building extensions or writing your own review tooling, it shows you exactly what patterns the Umbraco team cares about. The skill intelligently checks for local CMS source code before hitting GitHub, which is a nice touch for offline work.
