Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish readOnlyHint=true and openWorldHint=true, so the safety profile is known. The description adds the context that this is a bulk result-retrieval operation, but it does not disclose relevant behavior such as whether results are available immediately, require polling, or may be partial if the bulk search is still running.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
