Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It does convey that this is a mutating toggle operation (hide/unhide) and shows the HTTP method and endpoint, which helps. But it does not explicitly state side effects (e.g., whether hiding removes the comment from public view, whether it is reversible beyond toggling), authorization needs beyond 'your Page's post', or any rate-limit considerations. The disclosure is adequate for a simple toggle but not comprehensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
