Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description bears full responsibility for behavioral disclosure. It explicitly states that the operation is irreversible, which is the most critical behavioral trait for a delete operation. It also instructs to confirm with the user, indicating the expected interaction pattern. It does not mention potential side effects like cascading deletes, but for a simple single-resource delete, this is sufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
