Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, covering safety profile. The description adds 'current' indicating a snapshot, but does not disclose details about default scope, language behavior, or response format. Annotation coverage lowers the bar, yet the description adds minimal behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
