Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the disclosure burden. 'List all queues' implies a non-mutating read, but it says nothing about ordering, pagination, or whether the listing reflects active versus disabled queues. For a zero-parameter read tool the risk is low, so this is a modest rather than severe gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
