Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true, so the safety profile is covered. The description adds that the tool 'Returns a single view' and lists the metrics, but provides no extra behavioral details such as authentication requirements, rate limits, or data freshness, which falls short of adding significant value beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
