Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. 'List' implies a read-only operation, which is useful, but the description does not disclose whether dependencies are resolved recursively, what happens for invalid paths, or any permission requirements. The output fields (path, uid, type) are stated, but deeper behavioral traits are missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
