Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=false and destructiveHint=false, so the agent knows this is a non-destructive mutation. The description adds that the page is AI-generated, which is useful context, but it does not disclose other behavioral aspects like whether the page is immediately published, if credits are consumed, or if there is any asynchronous processing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
