Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the full burden of behavioral disclosure. It only says 'overview and statistics' but does not specify what data is returned, whether it is read-only, if there are pagination or size limits, or what the output structure looks like. This lack of detail is a notable gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
