Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full behavioral disclosure burden. 'Get' implies a read-only operation, but the description does not explain what the quota value means, whether the response contains usage and limits, or any authentication/failure behavior. This is minimal disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
