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 indicates a read-only operation ('List') but doesn't specify permissions, rate limits, pagination, or response format. The mention of 'metadata' is vague without detailing what metadata is included.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
