Storybook for React Native is a development environment for designing and testing individual React Native components without running the whole application. It is for React Native and Expo developers who need to build components in isolation, document them with stories, and test them. The catalogue skills, plugins, instructions, MCP integration, and command support workflows around using Storybook for React Native.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 5.1 | $0.00102 | $0.01273 |
| Opus 5.5 | $0.00041 | $0.00509 |
| Sonnet 5.5 | $0.00020 | $0.00255 |
| Haiku 4.5 | $0.00010 | $0.00127 |
Grade A, and why
setup-react-native-storybook 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.
React Native Storybook Setup
Add @storybook/react-native v10 to a React Native project.
Important: Detect the project's package manager (look for yarn.lock, pnpm-lock.yaml, or bun.lockb) and use it for all install/run commands instead of npm. The examples below use npm but substitute accordingly (e.g. yarn add instead of npm install, yarn storybook instead of npm run storybook). For Expo projects, use npx expo install (or bunx expo install, etc.) to install dependencies so Expo can resolve compatible versions.
For the init command, use <pm> create storybook with the flags shown below. Only npm needs -- before the flags. Never use npx/bunx etc for this.
Four setup flows based on project type:
- Expo (no router) - see references/expo-setup.md
- Expo with Expo Router - see references/expo-router-setup.md
- React Native CLI (no Expo) - see references/react-native-cli-setup.md
- Re.Pack (rspack/webpack) - see references/repack-setup.md
Flow Selection
- Project has
rspack.configorwebpack.configand uses@callstack/repack-> Re.Pack - Project has
app/directory with_layout.tsxand usesexpo-router-> Expo Router - Project uses Expo but not file-based routing -> Expo
- Project uses
@react-native-community/cliwith no Expo -> React Native CLI
Common Steps (all flows)
1. Run CLI Init
npm create storybook -- --type react_native --yes
# or: pnpm create storybook --type react_native --yes
# or: bun create storybook --type react_native --yes
This installs dependencies and creates .rnstorybook/ with main.ts, preview.tsx, and index.tsx.
2. Enable WebSockets in .rnstorybook/index.tsx
Update the generated .rnstorybook/index.tsx to enable WebSocket support. This is required for remote control and syncing with the Storybook web companion:
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
