Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds no behavioral context beyond restating the purpose—no information about authentication needs, rate limits, or side effects. With annotations present, the bar is lower, but this description contributes nothing extra.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
