Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry behavioral transparency on its own. It does convey that the operation is a read via 'Query' and that it returns status/progress/result, but it does not disclose what happens if the job is not found, whether it returns immediately, or whether it can be called repeatedly. This is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
