## Findings

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

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

annotations: {"readOnlyHint":true}; The name "healthgorilla_list_observations" says "list": a word for reading.
```


## Deletes or cancels (2)

Removes, cancels or revokes something. Claude Code: deny.
