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 only states it gets file info, implying a read operation, but does not disclose limitations, authorization needs, or potential side effects. For a simple read tool, minimal info is provided.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
