| You send                                           | While                                 | Result                                                                                                                                                   |

| A message                                          | A turn is running                     | Steer: the model sees the message after the tool call in progress returns. The turn continues.                                                           |
| A message                                          | An approval, question or plan is open | Answers or declines the prompt. See [Approvals, questions and plans](/slack/approvals-questions-plans).                                                  |
| `!stop` or `!esc`                                  | A turn is running                     | The turn stops. Open prompts are cancelled.                                                                                                              |
| `!! <text>`                                        | Any time                              | Listed in `!help` as interrupt-and-redirect, but answers "unknown command `!!`, try `!help`" and interrupts nothing. Send `!stop`, then the new message. |
| Slack's stop button on the agent status            | A turn is running                     | Same as `!stop`.                                                                                                                                         |
| Another `!` command                                | Any time                              | Runs at once, outside the turn.                                                                                                                          |
| A model tier alone (`+smart`, `+fast`, `+default`) | Any time                              | Switches the session's model; nothing is sent to the agent.                                                                                              |

## Steering

* The bot adds an :eyes: reaction to a message that arrives mid-turn.
* The turn's output continues in a new message below yours.
* In a [shared thread](/slack/shared-threads#who-can-steer), anyone whose messages are delivered can steer.

## Stopping

* Steps still running show "interrupted", and the turn's footer starts with the stop reason.
* The next message continues the same conversation.
* While the host is offline, Slack's stop button does nothing. A typed `!stop` is queued like any message.
