Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate the operation is a mutation (readOnlyHint=false) and not destructive (destructiveHint=false), and the description does not contradict them. However, the description adds no extra behavioral detail, such as whether folder contents or IDs remain unaffected by the rename, so transparency is adequate but minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
