Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so safety is covered. The description adds that matching is by name and that results include URLs and latest versions, but it does not disclose possible limitations such as pagination, result caps, or exact/partial matching behavior. This is acceptable but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
