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 mentions the return format (JSON) and error handling (Chinese error messages), but lacks details on permissions, rate limits, side effects, or what '詳細資訊' includes. For a read operation with no annotations, this is insufficient behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
