## What it does

The skill is a table of contents. Each topic lives in its own `SKILL.md` under `references/`, and the agent reads the file that matches the job before writing, reviewing or debugging code. That keeps the advice out of context until a topic actually comes up.

It turns on by itself when the working directory holds a `package.json` depending on `react-native`, `expo` or `expo-router`. Topics cover animations on Reanimated 4 (CSS, shared values, layout, GPU shaders via WebGPU and TypeGPU), touch handling with Gesture Handler, vector work in `react-native-svg`, audio through `react-native-audio-api`, rich text editing, and on-device models with ExecuTorch. Two more files deal with JSI and C++ modules, and with moving computation off the JS thread using `react-native-worklets`.

Bundle Mode has its own file, and it matters: enabling it means patching `metro` and `metro-runtime` for your package manager, and the file walks through the SHA-1 failure and the lost Fast Refresh that follow. The guidance assumes the New Architecture, so an app still on the old bridge will not match some of it. Supported clients are Claude, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add software-mansion-labs/skills --skill react-native-best-practices -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/react-native-best-practices/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/react-native-best-practices/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add software-mansion-labs/skills --skill react-native-best-practices -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/react-native-best-practices/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add software-mansion-labs/skills --skill react-native-best-practices -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/react-native-best-practices/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install software-mansion-labs/skills react-native-best-practices
```

2. **Manually: put the files in place**
- File: `.github/skills/react-native-best-practices/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add software-mansion-labs/skills --skill react-native-best-practices -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/software-mansion-labs/skills --path skills/react-native-best-practices
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/react-native-best-practices/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add software-mansion-labs/skills --skill react-native-best-practices -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/software-mansion-labs/skills/tree/HEAD/skills/react-native-best-practices/SKILL.md

## When to use it
- work out what runs on a worklet and what has to come back to JS
- build a drag gesture with Gesture Handler that does not fight the animation
- move heavy computation off the JS thread with react-native-worklets
- enable Bundle Mode and get past SHA-1 errors
- write a C++ module on JSI without breaking threading rules

## Example prompts
- Before you touch the cart screen, read `references/gestures/SKILL.md` and rewrite the swipe gesture to match
- The animation stutters — check `references/animations/SKILL.md` and tell me why
- I need to parse JSON inside a worklet; look at `references/multithreading/SKILL.md` and suggest an approach
