Clerk Expo

Adds Clerk authentication to Expo and React Native apps via @clerk/expo. You get prebuilt native components (AuthView, UserButton) for the fastest path to working auth, or drop down to custom flows when you need Expo Go compatibility, web targets, or your own UI. Handles email, password, SMS OTP, MFA, OAuth, native Google and Apple sign-in, Expo Router guards, and biometrics. The skill enforces current v3.4+ APIs (method-based flows like signIn.password(), useSSO not useOAuth) and won't let you ship deprecated patterns. Build-type aware: it knows what needs a development build versus what runs in Expo Go, and it typechecks then builds to verify against your installed SDK before calling it done.
