Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide no positive safety hints, so the description's disclosure of rate limiting for free accounts, the list of audit areas, and the scored result add meaningful behavioral context. It does not describe side effects or authentication requirements, but for an audit tool this is reasonably transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
