# CLI Channel

The CLI connects to Luna via SignalR. `CliChannel` is a server-side adapter that bridges the SignalR hub to the `IChannel` interface defined in [[Channels]].

## How It Works

`CliChannel` wraps `IChatHubContext` from [[Core]] to send streaming responses back to the connected SignalR client. The flow:

1. The `ChatHub` receives a message from the CLI client over SignalR.
2. `ChatHub` calls `RaiseMessageReceived` on the `CliChannel` instance.
3. The [[Channels|ChannelManager]] picks up the event and routes it through `SessionManager.RouteMessagesAsync`.
4. The resulting `IAsyncEnumerable<ChatStreamUpdate>` is passed back to `CliChannel.SendStreamingMessageAsync`.
5. `CliChannel` forwards the stream to the SignalR client via `IChatHubContext`.

## Key Characteristics

- **Server-side adapter**: `CliChannel` lives on the server; the actual CLI is a separate SignalR client.
- **Single connection**: One `CliChannel` instance maps to the SignalR hub connection.
- **No polling**: Unlike [[Telegram Channel]], the CLI uses persistent WebSocket connections via SignalR.
