What problem does it solve?
This skill helps you implement secure, correct Clerk authentication in Expo / React Native apps without guessing the right native setup details.
Core Features & Use Cases
- Expo / React Native Clerk integration: Sets up
<ClerkProvider> with the correct publishableKey wiring and token persistence using @clerk/expo/token-cache.
- Flow-specific implementation guidance: Guides you to choose and implement either prebuilt UI components (
AuthView, UserButton) or custom hook-driven flows (useSignIn, useSignUp, useSSO) based on your app and requirements.
- Source-driven, status-accurate behavior: Ensures custom flows follow Clerk hook return/status semantics and match the installed
@clerk/expo behavior.
- Safety and gating: Enforces prerequisites like flow choice, required keys, correct platform/build usage (not Expo Go for native hooks), and required environment checks for custom strategy coverage.
Quick Start
Ask the agent: “Implement Clerk authentication for my Expo React Native app using @clerk/expo with the prebuilt AuthView/UserButton flow, and use this publishable key: <PASTE_KEY>.”
