Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states the tool is read-only (get bid history) and notes a requirement, but does not disclose rate limits, response format, pagination, or any side effects. The description is minimal in behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
