Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description provides no behavioral context beyond what the annotations already convey (read-only, idempotent, non-destructive). It does not explain what an auth nonce is for, what it returns, or any prerequisites. With annotations present, the bar is lower, but the description adds no extra transparency value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
