Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Return,' which implies a read-only operation, but it does not explicitly state that it has no side effects, nor does it disclose any details about polling behavior, job lifecycle, or how errors are surfaced. This is a significant gap for a status-query tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
