Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries full burden for disclosing side effects. It does mention a $0.01 USDC payment, which is a notable behavioral trait, but it does not state whether the tool is read-only or has other destructive side effects. The disclosed cost is partial transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
