Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the read-only behavior is established. The description adds no new behavioral traits beyond repeating 'read-only'. It does not discuss error handling, permissions, rate limits, or any side effects. With annotations covering the safety profile, the description contributes minimal additional transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
