Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructive=true, idempotent=true, and readOnly=false, providing the safety profile structurally. The description adds no context about what is deleted, whether associated data is cascaded, or any permission requirements, so it offers nothing beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
