Device Management

View, rename, and monitor all devices connected through Tai Link.

## Device list

Open the **Tai Link** panel in Yao Agents. Every registered device appears as a card showing:

| Field | Description |
|-------|-------------|
| Display name | Hostname or the name you set via `--display-name` / `config.yml` |
| Status | **Online** (green) or **Offline** (gray) |
| OS / Arch | Operating system and CPU architecture (e.g. linux/amd64, darwin/arm64) |
| Version | Tai Link build version |
| Capabilities | Icons for Docker, K8s, VNC, Host Exec — only the features detected at startup |

## Device detail

Click a device card to open its detail page. From here you can:

- **Remote Desktop** — open a VNC session to the device.
- **Workspaces** — browse and manage file sync workspaces.
- View connection logs and runtime information.

## Rename a device

Set the display name when starting Tai Link:

```bash
tai server --display-name "Build Server" http://<YOUR_YAO_SERVER>:5099
```

Or in `config.yml`:

```yaml
yao:
  display_name: "Build Server"
```

The name updates in Yao Agents after the next registration heartbeat.

## Remove a device

To disconnect a device:

1. Stop Tai Link on the remote machine (`Ctrl+C` or stop the Docker container).
2. The device status changes to **Offline** in the UI.

To remove credentials from the remote machine entirely:

```bash
tai logout
```
