Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate a mutating, non-idempotent operation (readOnlyHint=false, idempotentHint=false), so the description does not need to restate that. However, it adds no additional behavioral context—such as whether the clone copies all agent settings, whether it is deep or shallow, or what resource is returned. The core action is clear, but beyond that, the description is silent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
