Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden. It indicates a read-only operation ('Get list') and names the folder, but it does not disclose how the list is returned, whether it is sorted, or whether it may fail for missing folders.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
