description: "Run the Vite + React UI for testing the daemon."

The demo frontend lives at `frontend/packages/inspector`.

## Run locally

```bash
pnpm install
pnpm --filter @sandbox-agent/inspector dev
```

The UI expects:

- Endpoint (e.g. `http://127.0.0.1:2468`)
- Optional token

When running the daemon, the inspector is also served automatically at `http://127.0.0.1:2468/ui`.

If you see CORS errors, enable CORS on the daemon with `sandbox-daemon server --cors-allow-origin` and related flags.
