> ## Agent Instructions
> The canonical docs host is https://momentic.ai/docs. Append .md to any page URL for clean Markdown. Fetch https://momentic.ai/docs/llms.txt for the page index and https://momentic.ai/docs/llms-full.txt for every page in one file.
> For an unattended setup, run `npx --yes @momentic/wizard@latest -y --platform web --editor-tools skills` (use `--platform ios` or `--platform android` for mobile). Never run an interactive command in a non-TTY shell.
> You cannot complete the browser sign-in yourself. Read the API key from the MOMENTIC_API_KEY environment variable, or ask the user to create one at https://app.momentic.ai/settings/api-keys and paste it back.
> Momentic's capability summary for agents is at https://momentic.ai/docs/skill.md. Install the skills with `npx skills@latest add momentic-ai/skills`.
> Tests are YAML files in the user's repository. Use only the step names listed at https://momentic.ai/docs/reference/commands.md and the file structure at https://momentic.ai/docs/core-concepts/file-format.md. Do not invent step names, config keys, or CLI flags.
> Web tests run on Chromium, iOS tests on simulators, and Android tests on emulators. Physical devices are not supported.

# mo stop

> Stop the active turn of a Mo session.

Interrupt what Mo is doing right now. Mo cancels its in-flight tool work and the
session goes idle with its history intact, so you can resume it later with
[`mo send`](/docs/cli-reference/mo/commands/send). Use it when Mo is testing the
wrong thing or you want to pause the session.

```bash theme={null}
mo stop <session-id>
```

## Arguments

<ParamField path="<session-id>" type="string" required>
  The session whose active turn to stop.
</ParamField>

## Output

On success the command prints `Stopped Mo session <session-id>.` Stopping a
session that is already idle succeeds as well.

## Notes

* `stop` does not archive the session. Use
  [`mo archive`](/docs/cli-reference/mo/commands/archive) when you are finished with
  it.
* To stop and give new instructions in one step, use `mo send`, which stops the
  active turn before delivering your message.
