Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. It discloses that the operation is a soft-delete (implying recoverability) and affects all active versions, which is valuable. However, it omits permissions required, whether the action is reversible, and any side effects beyond scope.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
