Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the behavioral disclosure burden. It discloses the task, jurisdiction, speed, target users, and the pay-per-use cost of 25.0 USDC on Base, which is useful. However, it does not explain the output format or other execution behavior, and there is no output schema to fill that gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
