Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=false, so safety and scope are covered. The description adds genuinely new behavioral context — result ordering (newest first) and the fields each entry carries — but says nothing about result size, pagination, or what happens when no drafts exist.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
