Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint=true and destructiveHint=false, and the description is consistent with a read-only operation. The description does not add extra behavioral context such as return format or error handling, but given the tool's simplicity, the annotations are sufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
