Umbraco Conditions

This handles Umbraco's extension conditions, the gatekeeping system that controls when and where backoffice extensions appear. You'd use it when building custom dashboards, workspace actions, or views that should only show up in specific contexts like a particular section, content type, or user permission level. It fetches the latest docs from Umbraco's site and includes examples for common scenarios like section matching, workspace filtering, and user permissions. All conditions use AND logic, so every one must pass. The skill covers both built-in conditions and how to build custom ones by extending UmbConditionBase. Honestly, conditions are foundational to any serious Umbraco customization work, so this is one you'll reference constantly if you're extending the backoffice.

Umbraco Conditions

What is it?

Extension Conditions enable developers to declare requirements that must be met before an extension becomes available in the backoffice. They function as gatekeeping mechanisms controlling when and where extensions appear based on context like section, workspace, user permissions, or content type. Multiple conditions use AND logic—all must pass for the extension to display.
