Designing app actions beyond a screen.

A useful app action begins with a clear task: save an item, start an activity or find something already in the product. Give the action a name that describes the result, and make each required input understandable without the context of a screen.

When planning an App Intents integration, identify the domain logic the action needs. Keep that logic separate from the presentation so the app and its action can share the same rules. Plan for missing data, signed-out users and situations where the action cannot finish.

Test the action in the contexts and OS versions the product supports. Check that success is clear, errors are useful and repeated requests behave sensibly. Good integration design starts with a small action that works predictably, then grows from what users need.
