Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the full burden. It merely states the delete action without disclosing whether it is reversible, any side effects, or what happens to the autoresponder after deletion. The description adds no behavioral detail beyond the tool name.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
