Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations are absent, so the description carries the full burden. It only repeats the action implied by the name, providing no additional behavioral details such as whether deletion is permanent, if it triggers side effects, or if special permissions are required. A destructive action with zero safety annotations merits more disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
