Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden of explaining behavior. It does disclose what data the tool returns (economy, population, government, provinces), which is useful. However, it does not mention read-only status, response structure, or potential limitations, leaving some behavioral ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
