Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states 'Delete' implying a destructive, irreversible action, but does not clarify whether deletion requires special permissions, what happens to associated data, or that the action cannot be undone. The lack of a response format also obscures success/failure behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
