Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It does add useful traits: the queue is persistent and the items are ordered. However, it does not disclose behavior for invalid or missing queue_id, whether the operation is read-only, or what the returned object structure looks like beyond 'ordered items'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
