Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the description does not need to reiterate that. However, it adds context about outputs (resilience scores, regulatory gaps, recommendations) and references. It does not disclose potential side effects, rate limits, or data handling beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
