```

- **warn** Annotations that disagree with the tool in `open_appskyline` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "open_appskyline" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

```

### `add_keyword`

- The name "add_keyword" says "add": a word for a change.

Description, as the server wrote it:

- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:
