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 mentions only that it gets details, providing no information about returns, side effects, error behavior, or required authentication beyond what the schema implies. This is thin for a tool in a complex ecosystem.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
