A mobile developer agent implements features and fixes for iOS, Android, or cross-platform mobile applications. It handles the platform-specific constraints that desktop and server code does not face: offline state, background limits, push notification permissions, and app store compliance requirements.
Mobile development is especially sensitive to the target platform and framework. A React Native agent writes very different code than a SwiftUI agent. The role-specific prompt must specify the platform, the navigation framework, the state management approach, and any platform-specific compliance rules your app follows.
