Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description does not disclose behavioral traits such as return format, the meaning of 'prices' (e.g., bid/ask, mid), or any side semantics despite the `side` parameter. It does not mention rate limits, authentication, or any side effects. The tool is a read operation, but the description leaves the agent guessing about response structure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
