Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the full burden of disclosing behavior. It does reveal that the operation changes which task is current, but it does not explain whether this also starts execution, whether it is reversible, what permissions are required, or what happens to the previously current task.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
