Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the burden. 'List items currently waiting' clearly implies a read-only operation and a specific state, but it does not disclose ordering, pagination, or what happens when the queue is empty. The output schema may cover return shape, but behavioral details are limited.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
