Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of explaining behavior, and it does state that the tool retrieves details including fields, which conveys a read-oriented operation. It does not disclose potential outcomes such as not-found behavior, error cases, or whether the response contains the full view object, but for a simple getter the implied read-only behavior is reasonably clear.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
