Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It describes the tool as returning data and lists parameters, which implies a read-only operation. However, it does not explicitly state that no data is modified, nor does it cover error handling or authentication requirements. The description is adequate but not rich in behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
