Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already mark destructiveHint=true, so the destructive nature is known. The description adds useful context beyond annotations: it is a 'Paid feature' (cost/authorization implication) and only affects visits the user logged, not shared records. It does not detail irreversibility, but that is already signaled by destructiveHint.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
