Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. The description does not disclose what happens with an invalid ID (does it error or return null?), whether the entry is a single object or wrapper, or any behavioral characteristics. '取得' implies a read operation, but with zero annotations and no behavioral detail, this is a thin disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
