Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full responsibility for behavioral disclosure. It states the operation is a removal, implying a destructive action, but does not mention permanence, effects on related data, error behavior (e.g., if the case is not attached), or any side effects. An agent cannot anticipate the operational consequences from this description alone.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
