Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the behavioral disclosure burden. '列出' (list) implies a read-only operation, but the description does not disclose output format, pagination, the meaning of advanced mock expectations, or any side effects. It provides only the most basic behavioral signal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
