## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "screen_mark" says "mark": a word for a change.
```

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

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