Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states 'List' which implies a read-only operation, but it does not disclose what the delete queue represents, whether results are paginated or ordered, whether any authentication or permissions are needed, or what the response contains. The phrase 'delete queue' is ambiguous.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
