Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral burden. 'List' implies a read-only operation, which is clear enough at a basic level. However, the description does not disclose what exactly the list contains (e.g., names, paths, content snippets) or how the result is structured.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
