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 enumerates the output fields (source, date, licence, citation) but does not explicitly state that the operation is read-only or has no side effects. For a simple provenance getter, this is acceptable 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.
