Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral disclosure burden. It does state the core behavior (highest or lowest rows by a numeric column), but it does not describe limit/default behavior, tie handling, non-numeric handling, or the returned row shape. Without an output schema, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
