Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the behavioral burden. It indicates a read-only operation ('Get') with no side effects, which is adequate for this simple getter. However, it does not disclose what the response contains (though an output schema exists) or any potential errors. The transparency is acceptable but not enhanced beyond the basic action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
