Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full responsibility for behavioral disclosure. It mentions that calls are billed with metered credits, which is useful context, but it says nothing about request/response behavior, side effects, or whether generation is synchronous or asynchronous. The billing note is the only behavior disclosed beyond generating content.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
