Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It says the task tree must be '正在运行的' (currently running), implying a condition, but does not disclose side effects on child tasks, authentication requirements, idempotency, error behavior, or what happens to incomplete tasks.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
