## Command group help from OpenAPI tags

commands

Command groups now describe themselves in `--help` using prose from your spec. The first sentence of the attributed root-level `tags[]` description becomes the group's short line in the parent command's table, and the full description becomes its `--help` body. Override either with `x-fern-groups`.

**`openapi.yml`**

```yaml title="openapi.yml"
x-fern-groups:
  plants:
    summary: Manage your greenhouse
    description: Browse, water, and repot plants. Watering respects each plant's schedule.
```
