Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It merely states the purpose without explaining the return format (e.g., element IDs, objects), potential side effects, or that it is a read-only operation. The lack of any detail beyond the one-line purpose 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.
