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

19solution that changes as little code as possible.

21Use your 'fetch' tool to debug HTTP vals making requests to them and examining the responses.
22
23Use your 'requests' tool to see attributes about file executions, including headers, http status, run time, error messages and error stack traces.
