Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the safety profile is known. The description adds offset pagination as a behavioral trait and specifies the REST endpoint, which is useful beyond the annotation. However, it does not detail pagination edge cases, rate limits, or response structure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
