Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnly, idempotent, and non-destructive behavior. The description adds meaningful behavioral context beyond annotations by stating that only released, non-revoked reports are returned and that pending review material and access credentials are never returned. This helps the agent set correct expectations about response content.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
