## Event types

Common events include:

- `mention`
- `assign`

## Quiet hours & digest

You can define quiet hours and digest schedules to reduce noise. These settings are available in user notification preferences and can be managed via the CLI.

```bash
och notify settings --show
```

## CLI usage

```bash
och notify list --unread
och notify read --all
```

## Tips

- Turn on Slack for `review_request` and `merge_queue` events.
- Use quiet hours to avoid off‑hours alerting.
- Combine with automation rules for consistent team practices.
