Add Clerk authentication to Expo and React Native apps using @clerk/expo. Use for Expo setup, prebuilt native components (AuthView, UserButton), custom sign-in/sign-up flows (email, password, SMS/phone OTP, MFA), OAuth/SSO, native Google/Apple sign-in, Expo Router protected routes, biometrics, and push notifications. Do not use for native Swift/iOS, native Android/Kotlin, or web-only framework projects.

Audits the bundled `clerk-expo` skill against the @clerk/expo SDK source and clerk-docs, then proposes or applies updates. Use when the user says "audit the expo skill", "update the clerk-expo skill", "check clerk-expo against the SDK", "resync clerk-expo skill", "run audit-expo-skill", or after @clerk/expo ships a minor or major release.

Add Clerk authentication to any project by following the official quickstart guides.
