Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the annotations, the description adds meaningful behavioral context: disabling is unlimited, immediate, and any price reduction is deferred to the end of the billing cycle. It does not contradict the destructiveHint annotation, since it clearly frames the action as a status change rather than deletion.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
