Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It discloses cost ('$0.020 USDC') and service provider ('groundtruth'), which are useful behavioral traits. However, it doesn't cover other important aspects like authentication needs, rate limits, error handling, or what 'verify' entails operationally (e.g., what verification means in this context).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
