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 | $0.00000 | $0.00511 |
| Opus 5 | $0.00000 | $0.00255 |
| Sonnet 5 | $0.00000 | $0.00102 |
| Haiku 4.5 | $0.00000 | $0.00051 |
Grade A, and why
react-native 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 2d 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.
What it actually says
React Native / Expo PUDO Checklist
1. PLAN (Architecture & Strategy)
- Failure Modes & Store Review: Identify App Store / Play Store review edge cases, account deletion rules, and blocker policies BEFORE polishing the UI.
- Native Build Config: Establish EAS Build profiles or Bare RN configs early as they are silent killers. Identify constraints with third-party SDKs.
- Framework Base: Decide between Expo Managed Workflow vs. Bare React Native based on native module requirements.
- Navigation: Plan navigation structure using React Navigation or Expo Router (file-based).
- Offline & Storage: Plan offline-first capabilities using AsyncStorage, MMKV, or SQLite.
- UI Library: Select a styling strategy (Tailwind via NativeWind, Tamagui, or StyleSheet).
2. UNDERSTAND (Context & Auditing)
- Native Dependencies & Plugins: Audit
package.jsonfor libraries requiring auto-linking or custom native code (EAS Plugins). Prioritize diagnosing native dependency crashes. - Platform Differences: Identify features that require diverging logic between iOS (
.ios.tsx) and Android (.android.tsx). - State Management: Review global state for performance impacts on re-renders (context vs. atomic state like Jotai).
3. DEVELOP (Implementation)
- Layouts & Flexbox: Build fluid, responsive layouts using React Native Flexbox. Handle Safe Areas (notches, dynamic islands).
- Interactivity: Use
AnimatedAPI orreact-native-reanimatedfor 60fps/120fps animations on the UI thread. - Lists: Replace
ScrollViewwithFlatListorFlashListfor rendering large datasets efficiently. - Permissions: Implement graceful permission requests (Camera, Location, Push Notifications).
4. OPTIMIZE (Performance & Review)
- JS Thread vs UI Thread: Ensure heavy calculations do not block the JS thread (causing UI stutter).
- Image Optimization: Use
expo-imageorreact-native-fast-imagefor caching and aggressive memoization. - App Size: Strip unused native modules, compress assets, and use Hermes engine to optimize startup time.
- Testing: Implement automated E2E flows with Maestro/Detox and unit tests using React Native Testing Library.
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 is a skill published in the GitHub repository DongDuong2001/pudo-code-system (5 stars, last pushed 26d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 511 tokens. 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.
