React Native mobile app (Expo) that provides the Syllabye chat and calendar UI.

• React Native + Expo – cross-platform mobile UI for iOS/Android
• TypeScript – typed components, hooks, and API helpers
• React Navigation – tab navigation between Syllabus, Calendar, and Syl AI screens
• Context API (AppContext) – stores auth session, classes, and user state across screens
• Fetch API – REST calls for auth, classes, syllabi, and events
• WebSockets – streaming chat and tool-call events from the backend (/chat/ws)
• FastAPI backend – consumed via src/api.ts using API_BASE_URL

The SylAiScreen uses helpers from src/api.ts:

• streamChatMessageWs – primary WebSocket-based streaming chat
  • Streams text chunks for the assistant message
  • Streams structured tool-call events so the UI can show live tasks
• streamChatMessage – HTTP streaming fallback when WebSockets are unavailable

The Syl AI UI shows:

• Incremental assistant responses as text streams in
• A small task strip at the top of the chat listing tools the agent is running (e.g. list_classes, create_event)
• An inline ... assistant bubble while the model is thinking before text arrives

Authentication is handled by AppContext:

• Persists JWT and user profile via AsyncStorage
• Exposes setSession and logout
• The Syl AI screen has a small circular logout button in the header that calls logout()

1. Start the backend API (see ../Syllabye-backend/README.md).

2. In this folder, install dependencies and run the app with Expo:

   npm install
   npm run start

3. Use the Expo CLI to open the app on an iOS simulator or device and point it at the running backend.
