Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral traits. It states the tool will '智能分配任务并互相协作' (intelligently assign tasks and collaborate), but lacks details on side effects, permissions, output format, or internal mechanics. This is insufficient for understanding the tool's full behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
