What Supercomputer calls a projection
A projection is the version of an approved app action made for one specific place. Siri, Shortcuts, MCP, and a command-line tool each need different code and presentation, but they can still use the same action ID and working app code.
Each place has its own needs
- App Intents describe actions, app data, searches, results, and how Apple features find them.
- MCP or a command-line tool may need a different data format, connection method, sign-in process, and error handling.
- A widget, control, or Live Activity has its own update rules and operating-system requirements.
No automatic support
Adding one connection does not make every related feature work. Each one must be planned, built, and tested in the real place where people will use it.
