Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and readOnlyHint=false, so the description adds the important nuance of permanence with 'Permanently delete'. However, it does not disclose other behavioral details such as side effects, error behavior when the asset does not exist, or authorization requirements. Given the strong annotation coverage, a score of 3 is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
