# cast stop

Stop a running agent and destroy its sandbox.

## Usage

cast stop <slug>
```

| `slug`   | The agent's unique slug | Yes      |

<Warning>
  Stopping an agent destroys its sandbox. All files and state inside the sandbox will be lost. The agent can be redeployed with `cast deploy`.

2. The agent status changes to `stopped`
3. The agent can no longer receive invocations until redeployed
