Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It does disclose one real behavioral trait — that properties are not fully materialized, making this a cheap enumeration — and "List" implies read-only. However, it says nothing about return shape, pagination, or error behavior for a missing asset path.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
