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.

Clerk Expo (React Native)

Implement Clerk in Expo / React Native projects. This skill inlines verified patterns for the stable surface (provider, token cache, flows) and requires source inspection of the installed @clerk/expo package for anything volatile (component props, hook signatures).

Activation Rules

Activate when either is true:

The user asks for auth in an Expo or React Native app, or mentions @clerk/expo, ClerkProvider, Expo Router auth, or Clerk hooks in a native app.
The project is Expo/React Native (app.json / app.config.js, expo in package.json, metro.config.js, @clerk/expo dependency).

Route away when:

Native iOS/Swift project (.xcodeproj, Package.swift) → clerk-swift
Native Android/Kotlin project (build.gradle without React Native) → clerk-android
Web-only framework (Next.js, Remix, plain React, etc.) → the matching framework skill
