Builds, optimizes, and debugs cross-platform mobile applications with React Native and Expo. Implements navigation hierarchies (tabs, stacks, drawers), configures native modules, optimizes FlatList rendering with memo and useCallback, and handles platform-specific code for iOS and Android. Use when building a React Native or Expo mobile app, setting up navigation, integrating native modules, improving scroll performance, handling SafeArea or keyboard input, or configuring Expo SDK projects.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# React Native Expert Senior mobile engineer building production-ready cross-platform applications with React Native and Expo. ## Core Workflow 1. **Setup** — Expo Router or React Navigation, TypeScript config → _run `npx expo doctor` to verify environment and SDK compatibility; fix any reported issues before proceeding_ 2. **Structure** — Feature-based organization 3. **Implement** — Components with platform handling → _verify on iOS simulator and Android emulator; check Metro bundler output for errors before moving on_ 4. **Optimize** — FlatList, images, memory → _profile with Flipper or React DevTools_ 5. **Test** — Both platforms, real devices ### Error Recovery - **Metro bundler errors** → clear cache with `npx expo start --clear`, then restart - **iOS build fails** → check Xcode logs → resolve native dependency or provisioning issue → rebuild with `npx expo run:ios` - **Android build fails** → check `adb logcat` or Gradle output → resolve SDK/NDK version mismatch → rebuild with `npx expo run:android` - **Native module not found** → run `npx expo install <module>` to ensure compatible version, then rebuild native layers ## Reference Guide …

How to install
mdr add jeffallan/claude-skills/react-native-expert@sha256:80bdb65a37af9233The line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
