Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It only states the action 'delete' without revealing whether deletion is permanent, cascades to related entities, requires special permissions, or what happens if the placement is not in draft status. Critical side-effect information is missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
