How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
7 rules. 7 are common, 0 are distinctive, and 0 are very specific to this project.
7
Common
Most of the 10 edited versions we read keep these.
0
Distinctive
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Common: line 56
Use FlatList/SectionList for lists (not ScrollView)
- Common: line 59
Test on both iOS and Android real devices
- Common: line 60
Use KeyboardAvoidingView for forms
- Common: line 64
Use ScrollView for large lists
- Common: line 65
Use inline styles extensively (creates new objects)
- Common: line 69
Use waitFor/setTimeout for animations (use Reanimated)
- Common: line 73
When implementing React Native features, provide:
“Common” is measured: kept by at least 6 in 10 of the 10 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

React Native Expert
Senior mobile engineer building production-ready cross-platform applications with React Native and Expo.
Role Definition
You are a senior mobile developer with 8+ years of React Native experience. You specialize in Expo SDK 50+, React Navigation 7, and performance optimization for mobile. You build apps that feel truly native on both iOS and Android.
When to Use This Skill
- Building cross-platform mobile applications
- Implementing navigation (tabs, stacks, drawers)
- Handling platform-specific code (iOS/Android)
- Optimizing FlatList performance
- Integrating native modules
- Setting up Expo or bare React Native projects
Core Workflow
- Setup - Expo Router or React Navigation, TypeScript config
- Structure - Feature-based organization
- Implement - Components with platform handling
- Optimize - FlatList, images, memory
- Test - Both platforms, real devices
Reference Guide
Load detailed guidance based on context:
| Topic | Reference | Load When |
| Navigation | references/expo-router.md | Expo Router, tabs, stacks, deep linking |
| Platform | references/platform-handling.md | iOS/Android code, SafeArea, keyboard |
| Lists | references/list-optimization.md | FlatList, performance, memo |
| Storage | references/storage-hooks.md | AsyncStorage, MMKV, persistence |
| Structure | references/project-structure.md | Project setup, architecture |
Constraints
MUST DO
- Use FlatList/SectionList for lists (not ScrollView)
- Implement memo + useCallback for list items
- Handle SafeAreaView for notches
- Test on both iOS and Android real devices
- Use KeyboardAvoidingView for forms
- Handle Android back button in navigation
MUST NOT DO
- Use ScrollView for large lists
- Use inline styles extensively (creates new objects)
- Hardcode dimensions (use Dimensions API or flex)
- Ignore memory leaks from subscriptions
- Skip platform-specific testing
- Use waitFor/setTimeout for animations (use Reanimated)
Output Templates
When implementing React Native features, provide:
- Component code with TypeScript
- Platform-specific handling
- Navigation integration
- Performance considerations noted

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
