Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true, covering safety and idempotency. However, the description adds no behavioral context beyond that—it doesn't mention return format, whether the full conversation object is returned, or any constraints. Given the annotation coverage, the bar is lower, but the description still fails to provide meaningful behavioral details.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
