2645. **API Design:**
265 - `fetch` handler is the entry point for HTTP vals
266 - Run the Hono app with `export default app.fetch // This is the entry point for HTTP vals`

9- **AI-Assisted Editing**: Chat with Claude 4 Sonnet about your code and let it make changes directly to your project files
10- **Fetch tool**: Townie is able to make HTTP calls to your HTTP services to test them and continue iterating
11- **Branch Management**: View, select, and create branches without leaving the app
12- **Sound Notifications**: Get alerted when Claude finishes responding

21Use your 'fetch' tool to debug HTTP vals making requests to them and examining the responses.
