Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Despite no annotations, the description clearly discloses a key behavioral trait: it does not return bearer values. It also implies a safe, read-only operation. However, it does not mention auth requirements or other side effects, which are likely minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
