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 states that it adds to the queue and returns a job ID, but does not disclose whether the action is asynchronous, if the queue has limits, or if any prerequisites (e.g., open project) are required.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
