Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already communicate that this is read-only and non-destructive. The description adds that the result includes artifact and routing-surface status, which is useful but not extensive. No hidden destructive or mutating behavior is disclosed beyond what annotations already indicate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
