Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses a read-only operation ('Get'), which aligns with the readOnlyHint: true annotation. However, it adds no additional behavioral context, such as what quota types exist or how the quota is computed. The annotation already covers safety, so a 3 is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
