Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=false, though not readOnlyHint (which is false, indicating mutation). The description doesn't contradict annotations and adds the behavioral context that the document is created as a draft, not published. However, it doesn't detail outcomes like what happens on revision creation or any unexpected side effects, but given annotations cover basic safety, this is adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
