Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral disclosure burden. 'List all' clearly indicates a read-only enumeration operation with no filtering, which is useful, but it does not describe the return shape, pagination, or error behavior. This is adequate for a simple list tool but minimally transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
