Mobile Stack Patterns

Mobile Stack Patterns

Use this skill when implementing or reviewing code in a mobile app repository.

Read references/mobile-platform-and-stack-guide.md for stack selection and framework source notes. Read project files before recommending packages or APIs.

Workflow

1. Detect the stack:
   • Expo or React Native: package.json, app.json, app.config.*, ios/, android/, Metro, Expo Router, React Navigation.
   • Flutter: pubspec.yaml, lib/, platform folders, Flutter tests.
   • iOS native: Xcode project/workspace, Swift packages, SwiftUI/UIKit files.
   • Android native: Gradle, Kotlin, Compose, AndroidManifest, modules.
2. Respect existing conventions:
   • routing/navigation;
   • state management;
   • styling/theming;
   • data fetching and cache;
   • error handling;
   • test style.
3. Design for mobile constraints:
   • app lifecycle;
   • background/foreground transitions;
   • permissions;
   • offline and retry;
   • deep links;
   • push notifications;
   • storage and secure storage.
4. Keep architecture practical:
   • feature folders or platform modules where local style supports it;
   • shared domain logic separated from view code when useful;
   • native bridges isolated and tested;
   • no broad rewrites for narrow UI tasks.
5. Verify with available project checks.

Output

Return:

• detected stack and assumptions
• implementation changes or review findings
• platform-specific branches
• tests/checks run or missing
• remaining risks
