Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds a behavioral detail beyond the annotations: it marks the request ready for review. Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, so the safety profile is covered; the description's added effect of changing readiness is useful context without contradiction.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
