Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions highest/lowest rows and numeric columns, but it doesn't state behavior around limit defaults, empty results, ties, non-numeric values, or whether the full row or only the selected column is returned. This leaves significant 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.
