# description

The human-readable summary shown in /hooks.

Required on every Catalog Entry—Hooks **and** Presets. It is the summary
the `/hooks` panel shows:

<!-- docs-example:valid -->

```json
{
  "local": {
    "no-env-access": {
      "description": "Blocks reads and writes to .env files.",
      "event": "tool_call",
      "shell": "false"
    }
  }
}
```

- **Type** `string` · required · every Hook and Preset
- Shown as the identifying summary in `/hooks` when a reader decides whether
  to enable or edit the entry.
- Not the Event or the command: `event`, `shell`, `when`, and `filter` carry
  behavior, while `description` only explains it.
