Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It clearly indicates a metadata/inspection operation and describes the output, but it does not explicitly state that the call is read-only or has no side effects. This is adequate for a zero-parameter field-listing tool but not fully transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
