## Findings

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

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