Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, and the description's 'GET' is consistent with those. The description adds the exact endpoint but no extra behavioral context such as auth scope, response shape, or any special restrictions; with annotations present, this is acceptable but not enriching.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
