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 partially meets that with the inline return shape, which reveals the tool is a non-destructive enumeration returning document metadata. It says nothing about ordering, whether documents from other workspaces are included, or cost/volume limits, which are the remaining behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
