Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and idempotentHint=true, so the bar is lower, yet the description still adds substantive context: the published page is read-only, link visibility depends on the public flag, and Admin rights are required. 'Always asks the user first' discloses an interactive confirmation behavior that no annotation conveys, though permanence/reversibility of publication (and how to undo it) is not stated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
