Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully disclose behavioral traits, but it does not. It fails to mention permissions, whether the page is published as draft, what happens with hierarchy, or the return value. The phrase 'hierarchy support' is an unsubstantiated claim since the schema only accepts title and content.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
