Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. 'Returns' implies a read-only query operation, which is appropriate. However, it doesn't disclose any behavioral traits like rate limits, authentication requirements, response format, or whether this is a lightweight or heavy query. The description is minimal but doesn't contradict any annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
