Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the whole behavioral burden. It states that the tool retrieves status and result_url, which implies a read-only operation, but it does not mention error behavior, whether the job must be finished, or if it can be polled repeatedly. The core behavior is clear, but deeper transparency is missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
