# WebChat (macOS app)

The macOS menu bar app embeds the WebChat UI as a native SwiftUI view. It
connects to the Gateway and defaults to the **main session** for the selected
agent (with a session switcher for other sessions).

- **Local mode**: connects directly to the local Gateway WebSocket.
- **Remote mode**: forwards the Gateway control port over SSH and uses that
  tunnel as the data plane.

## Launch & debugging

- Manual: Lobster menu → “Open Chat”.
- Auto‑open for testing:
  ```bash
  dist/OpenClaw.app/Contents/MacOS/OpenClaw --webchat
  ```
- Logs: `./scripts/clawlog.sh` (subsystem `bot.molt`, category `WebChatSwiftUI`).

## How it’s wired

- Data plane: Gateway WS methods `chat.history`, `chat.send`, `chat.abort`,
  `chat.inject` and events `chat`, `agent`, `presence`, `tick`, `health`.
- Session: defaults to the primary session (`main`, or `global` when scope is
  global). The UI can switch between sessions.
- Onboarding uses a dedicated session to keep first‑run setup separate.

## Security surface

- Remote mode forwards only the Gateway WebSocket control port over SSH.

## Known limitations

- The UI is optimized for chat sessions (not a full browser sandbox).
