Here's the prompt mentioned in the video:
Set up Google Sign-In and Apple Sign-In with Supabase Auth in this Expo React Native app. Use native sign-in libraries (@react-native-google-signin and expo-apple-authentication) with supabase.auth.signInWithIdToken() — not signInWithOAuth. Configure app.json plugins, set up persistent session storage, and handle both providers.
Set up Google Sign-In and Apple Sign-In with Supabase Auth in a React Native Expo app, using an AI agent to handle the heavy lifting.
In this tutorial, I'll walk through the full setup — from Firebase credentials and native sign-in libraries to persistent sessions and real device testing. I'll show you what the AI agent can do, what it can't, and how to get production-ready social authentication working end to end.
