What it does
React Native Performance is an agent skill from HoangNguyen0403/agent-skills-standard. Optimize React Native rendering for smooth 60fps mobile experiences. Use when optimizing React Native app performance, reducing re-renders, or fixing frame drops.
Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/optimization-guide.md`).
It sits in Mobile, covering Cross-platform mobile apps. It works with React Native and Android. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.
When your agent uses it
- Optimizing React Native app performance
- Reducing re-renders
- Fixing frame drops
Example prompts
- “/react-native-performance”
What it can do on your machine
Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
React Native Performance loads about 628 tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 47 tokens; SKILL.md has 233 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- Optimize React Native rendering for smooth 60fps mobile experiences. Use when optimizing React Native app performance, reducing re-renders, or fixing frame drops.
React Native Performance
Priority: P0 (CRITICAL)
Tune FlatList for 60fps
windowSize: Reduce to 5-10 for memory-heavy lists (default 21).initialNumToRendershould cover first viewport.getItemLayout: Provide for fixed-height items. Skips runtime measurement.removeClippedSubviews: Enable for Android (default true) to offload clipped items.maxToRenderPerBatch: Limit to 5-10 items per frame to prevent JS thread blockage.keyExtractor: Use stable unique IDs, never array index.
See optimization guide for FlatList configuration examples with getItemLayout, windowSize, and memoization patterns.
Accelerate Core Rendering
- ** Engine**: Ensure Hermes engine enabled (default in 0.7x). Verify via
global.HermesInternal. - Animations: Use Native Driver (
useNativeDriver: true) or Reanimated 3 for GPU-accelerated 60fps animations. - Re-renders: Use
React.memoanduseMemofor expensive props. Profile via Flipper (React DevTools) for flamegraphs. - Network: Batch API calls. Use React Query/Zustand to prevent unnecessary screen refreshes.
- Images: Use
react-native-fast-imagefor caching and priority. Avoid large PNGs; use WebP.
Reduce Bundle and Startup Time
- Hermes: Enable for faster startup (default in RN 0.70+).
- Tree Shaking: Remove unused imports.
- ProGuard/R8: Enable code shrinking on Android.
- Lazy Screens: Use
lazyprop for stack screens (enabled by default).
Anti-Patterns
- No ScrollView for Large Lists: Use FlatList.
- No Inline Styles: Use
StyleSheet.create(optimized). - No console.log in Production: Strip with babel plugin.
References
See references/optimization-guide.md for FlatList configuration, memoization rules, and bundle analysis.
