## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "build_packing_list" says "list": a word for reading.
```
