Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must disclose behavioral traits. It only states that a queue is deleted and a result string is returned, without mentioning that deletion is irreversible, whether messages in the queue are permanently removed, or any error conditions such as a nonexistent queue.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
