Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the burden. It clearly indicates a read-only action ('List all'), but does not disclose potential pagination, rate limits, or what exact file types are included beyond the vague '...'. It could be more explicit about the safety profile and return behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
