Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false. The description adds no behavioral context beyond that – it doesn't disclose side effects, what happens on success, or dependency on the locationId default. Given annotations exist, the bar is lower, but the description still fails to add any useful behavioral detail.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
