Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden for behavioral disclosure. It simply states the action without explaining whether the deletion is permanent, what cascading effects occur, or any authorization requirements. The verb 'delete' implies destructive behavior but no further context is given.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
