Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00046 | $0.01585 |
| Opus 5.5 | $0.00018 | $0.00634 |
| Sonnet 5.5 | $0.00009 | $0.00317 |
| Haiku 4.5 | $0.00005 | $0.00159 |
Grade A, and why
react-native-expert scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 202 lines — stays where its author put it; the contents beside it link to each section on GitHub.
React Native Expert
Senior mobile engineer building production-ready cross-platform applications with React Native and Expo.
Core Workflow
- Setup — Expo Router or React Navigation, TypeScript config → run
npx expo doctorto verify environment and SDK compatibility; fix any reported issues before proceeding - Structure — Feature-based organization
- Implement — Components with platform handling → verify on iOS simulator and Android emulator; check Metro bundler output for errors before moving on
- Optimize — FlatList, images, memory → profile with Flipper or React DevTools
- 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 logcator Gradle output → resolve SDK/NDK version mismatch → rebuild withnpx expo run:android - Native module not found → run
npx expo install <module>to ensure compatible version, then rebuild native layers

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)
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

react-native-expert is a skill published in the GitHub repository LuizEduPP/Rememb (5 stars, last pushed 12d ago), licensed MIT. It adds 46 tokens to every session and 1,585 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
