Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the burden of indicating the operation is a read-only list. 'List' clearly implies no mutation, but the description does not mention pagination, response details, or any access/scope limitations. For a zero-parameter read-only tool, this is acceptable 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.
