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. 'List' implies a read-only operation, but the description does not mention any potential limitations such as pagination, ordering, or authorization requirements. It is minimally adequate for a simple list operation but lacks depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
