Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is fully covered and the description correctly does not contradict it. It adds the returned-id semantics but says nothing about pagination behavior despite limit/offset parameters, nor about auth or rate limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
