Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnly=false, idempotent=true, openWorld=true, and destructive=false, and the description adds no behavioral context such as permission requirements, patch semantics, or what happens to unspecified fields. It does not contradict the annotations, but it contributes almost nothing beyond them.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
