Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It discloses the destructive nature and the confirmation requirement, but lacks details about irreversibility, cascading effects (e.g., on attachments), or authorization needs. The confirmation is a behavioral trait, but more context would improve transparency for a deletion operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
