Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only, non-destructive, idempotent behavior. The description does not contradict these, and it adds that the tool lists both active and completed searches, which is helpful. However, it does not disclose any potential behavioral traits like result limits or order.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
