Local Development

Testing with Chrome DevTools

To test locally, you need a Chrome DevTools WebSocket debugger URL.

1) Start Chrome with remote debugging enabled

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome \
  --remote-debugging-port=9222 \
  --user-data-dir=/tmp/chrome-debug

Keep this Chrome instance running while you test.

2) Verify and copy the WebSocket URL

Open http://localhost:9222/json/version in your browser. Find the webSocketDebuggerUrl field and copy its value. It will look like:

ws://localhost:9222/devtools/browser/<some-guid>

3) Set your .env

Create or update .env with your keys and the copied URL:

ANTHROPIC_API_KEY=sk-...
WEBSOCKET_DEBUGGER_URL=ws://localhost:9222/devtools/browser/<some-guid>
