How the author describes it

Migrate an existing web React app to a native iOS/Android app with Expo. Use when the user wants to turn a website into a mobile app, port a Next.js/Vite/CRA React codebase to React Native, reuse web code on native incrementally, or asks how web idioms (the DOM, CSS, React Router, localStorage, window) map to native. This is the end-to-end migration guide; use the `expo-dom` skill for the DOM-component mechanism itself.

From the description field of SKILL.md. Agents read this line to decide when to load the skill.

Principles
Run it as a loop (recommended)
The migration
1. Assess → write the worklist
2. Scaffold the shell
3. Shell it in DOM components — the day-one milestone
4. Strangle screens to native — by value
5. Wire data, auth, and storage
6. Ship
Verify by running, not compiling
