Umbraco Context Api

umbraco/umbraco-cms-backoffice-skills
310 installs26 stars
Summary

This teaches Claude how Umbraco's Context API works, which is the foundation for sharing data between backoffice components without tight coupling. You'll want this when building custom property editors, dashboards, or workspace extensions that need to access services like notifications, user info, or modal managers. The skill includes working examples for both consuming contexts (subscription vs one-time patterns) and providing your own, plus it always fetches fresh docs before generating code. The provider-consumer pattern takes a minute to grasp if you're new to Umbraco's web component architecture, but once it clicks you'll use it everywhere. Good coverage of common built-in contexts like UMB_NOTIFICATION_CONTEXT and UMB_WORKSPACE_CONTEXT that you'll reach for constantly.
