Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the behavioral disclosure. 'List' clearly signals a read-only operation, and the description states what is returned. However, it does not mention authentication expectations, pagination, error conditions, or whether an empty list is possible. For a zero-parameter read-only tool this is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
