What it does

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).
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
The project must run in Expo Go (no dev build).
The app targets web (native components don't render on web).

Requirements & configuration

Match what the user asked for, then load the reference(s) listed. Load only what the task needs.
2. Follow references/setup.md: install, env key, provider, token cache, config plugin, build type.
Walk the developer through one real sign-in, then confirm the session survives an app restart (token cache working).
6. Token cache — tokenCache from @clerk/expo/token-cache on ClerkProvider. Never use expo-secure-store directly for session tokens, never AsyncStorage.
10. Bot protection — custom sign-up screens must render <View nativeID="clerk-captcha" />; Clerk's bot protection is on by default and needs this mount point.
