Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It says 'Delete' but does not mention that the action is permanent, what happens if the anime isn't on the list, or any specific authentication requirements beyond the phrase 'authenticated user's.' For a destructive operation, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
