## What it does

The skill hands your agent a written set of React Native conventions: type-safe TypeScript, functional components and hooks over classes, files grouped by feature rather than by type. It covers code style, naming, TypeScript usage, performance, styling and general practice.

The performance section is the concrete part. Keep `useEffect`, `useState` and heavy work out of render, wrap components with static props in `React.memo()`, and tune FlatList with `removeClippedSubviews`, `maxToRenderPerBatch`, `windowSize` and `getItemLayout` when rows share a height. Anonymous functions in `renderItem` or event handlers are called out as a problem, since they defeat memoization. Styling goes through `StyleSheet.create()` or Styled Components, and images are meant to be optimized with `react-native-fast-image`.

These rules assume a specific stack: strict TypeScript in `tsconfig.json`, functional components, React Navigation for navigation and deep linking, Expo with EAS Build and over-the-air updates. On a class-component or plain-JavaScript codebase a good chunk of the advice won't apply. Install is one command through `npx skills add`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill react-native-cursor-rules -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill react-native-cursor-rules -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill react-native-cursor-rules -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Mindrally/skills react-native-cursor-rules
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill react-native-cursor-rules -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Mindrally/skills --path react-native-cursor-rules
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill react-native-cursor-rules -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/Mindrally/skills/tree/HEAD/react-native-cursor-rules/SKILL.md

## When to use it
- write typed components without falling back to `any`
- cut unnecessary re-renders with `React.memo()` and memoized callbacks
- tune a FlatList so long lists scroll without stutter
- group files by feature instead of by file type
- settle naming for components, variables and directories

## Example prompts
- add a profile screen in React Native with typed props
- why does this FlatList stutter while scrolling — check it against the skill rules
- refactor this component: move styles into StyleSheet.create and drop the anonymous handlers

# React Native Cursor Rules

Expert guidelines for React Native development by Will Sims, focusing on type-safe TypeScript code, performance optimization, and maintainable component architecture.

## Code Style and Structure

- Write concise, type-safe TypeScript code
- Use functional components and hooks instead of class components
- Ensure components are modular, reusable, and maintainable
- Organize files by feature, grouping related components, hooks, and styles

## Naming Conventions

- Use camelCase for variables and functions (e.g., `isFetchingData`, `handleUserInput`)
- Use PascalCase for components (e.g., `UserProfile`, `ChatScreen`)
- Directory names should be lowercase and hyphenated (e.g., `user-profile`, `chat-screen`)

## TypeScript Usage

- Use TypeScript for all components, favoring interfaces for props and state
- Enable strict typing in `tsconfig.json`
- Avoid `any` type; strive for precise types
- Utilize `React.FC` for defining functional components with props

## Performance Optimization

- Minimize `useEffect`, `useState`, and heavy computations in render methods
- Use `React.memo()` for components with static props to prevent unnecessary re-renders
- Optimize FlatLists with the following props:
  - `removeClippedSubviews`
  - `maxToRenderPerBatch`
  - `windowSize`
- Use `getItemLayout` for consistent-sized FlatList items
- Avoid anonymous functions in `renderItem` or event handlers

## UI and Styling

- Use consistent styling via `StyleSheet.create()` or Styled Components
- Ensure responsive design for different screen sizes and orientations
- Optimize images using `react-native-fast-image`

## Best Practices

- Follow React Native's threading model for smooth performance
- Utilize Expo's EAS Build and Over-The-Air updates
- Use React Navigation for navigation and deep linking
