## What it does

The skill drives `create-react-native-library` for you. It asks the agent to pick one of two flows first: a standalone library that can go to npm, or a local library inside an existing app. From there it follows the matching reference file.

Two docs sit in `references/`: `scaffold-library.md` for a new library with an Expo example, and `local-library.md` for a local library with autolinking. A problem-to-skill table maps each task to its entry point, so the agent does not start guessing. JS-only libraries, native modules and native UI components are all covered.

Check the current flags before you run anything: `npx create-react-native-library@latest --help`. The examples pass `--no-interactive` and `--yes`, so nothing prompts you — skip `--description`, `--type` or `--languages` and you get a scaffold you did not want. Worth checking those up front.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add callstackincubator/agent-skills --skill create-react-native-library -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add callstackincubator/agent-skills --skill create-react-native-library -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add callstackincubator/agent-skills --skill create-react-native-library -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install callstackincubator/agent-skills create-react-native-library
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add callstackincubator/agent-skills --skill create-react-native-library -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/callstackincubator/agent-skills --path skills/create-react-native-library
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add callstackincubator/agent-skills --skill create-react-native-library -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/callstackincubator/agent-skills/tree/HEAD/skills/create-react-native-library/SKILL.md

## When to use it
- scaffold a new React Native library for npm
- add a local native module to an existing app
- wrap a native SDK and expose it to JavaScript
- build a native UI component that renders native views
- decide between a standalone library and a local one

## Example prompts
- Scaffold a new React Native library called awesome-library with a turbo module and the Expo example
- Add a local turbo module to my app with create-react-native-library
- Wrap this native SDK in a module and expose it to JavaScript

# Create React Native Library

## Overview

Use this skill to scaffold a standalone React Native library or a local library inside an existing app, then continue with the correct implementation docs.

Examples:

- JS-only library that may use other React Native libraries
- Native modules that expose native functionality to JavaScript
- Native UI components that render native views in React Native

Choose one flow first:

- Use [scaffold-library.md][scaffold-library] when creating a new library that may be published to npm
- Use [local-library.md][local-library] when exposing native functionality in a React Native app

## When to Apply

Use this skill when:

- Creating or working on a React Native library with `create-react-native-library`
- Creating a native module or view in an existing app
- Wrapping native SDKs and exposing them to React Native

## Quick Reference

```bash
# Inspect current options before scaffolding
npx create-react-native-library@latest --help

# Scaffold a library with turbo modules and the Expo example app
npx create-react-native-library@latest awesome-library \
  --no-interactive \
  --yes \
  --description "A brief description of the library" \
  --type turbo-module \
  --languages kotlin-objc \
  --example expo

# Scaffold a local Turbo Module inside an existing app
cd MyApp
npx create-react-native-library@latest awesome-library \
  --local \
  --no-interactive \
  --yes \
  --description "A brief description of the library" \
  --type turbo-module \
  --languages kotlin-objc
```
