Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description clearly states this is a destructive/state-changing operation ('delete', 'move to trash', 'auto-purged'), but the annotations declare readOnlyHint: true. This is a direct annotation contradiction, so the behavioral transparency score must be 1.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
