Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=true, and the description's 'Get information' is consistent with these. However, the description adds no additional behavioral context such as authentication requirements, rate limits, or the nature of the returned data. With annotations covering the safety profile, a 3 is appropriate as it adds minimal value beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
