Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure. It explains what data the tool exposes and hints that it is a metadata lookup, but it does not explicitly state that the operation is read-only, describe the response shape, or mention any side effects. The absence of side-effect disclosure is a moderate gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
