Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full behavioral burden. It implies a read operation through 'List', but does not explain whether traversal is recursive, how deep it goes, what the default root behavior is, or what the result looks like. For a hierarchy-listing tool with zero annotation coverage, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
