App Feature Craft

Use this skill to turn an app request into a feature users can actually rely on. Default to shipping the smallest complete behavior, not a technical stub.

Workflow

1. Ground in the product before designing.

   • Inspect routes, screens, state stores, API clients, backend handlers, data models, tests, packaging scripts, and existing copy.
   • Resolve discoverable facts from the repo before asking the user.
   • If visual behavior matters, inspect screenshots or run the app.

2. Define the user-facing outcome.

   • State what the user can do after the change.
   • Identify the audience, success criteria, in/out of scope, data safety constraints, and where the behavior must appear.
   • Separate optional convenience from behavior required for a complete feature.
