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 states the delete action but does not disclose whether the deletion is permanent, whether notifications stop immediately, whether it is idempotent, or what happens if the id does not exist. There is no contradiction, but the transparency is minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
