Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate destructiveHint=true and readOnlyHint=false. The description reinforces this with 'permanently delete' and 'cannot be undone,' which adds marginal clarity. However, it does not disclose other behavioral details like what happens to associated resources, error states, or whether the deletion is immediate. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
