Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description explains the behavioral effect of each action ('修订变为正式内容' for accept, '还原为修订前状态' for reject). However, with no annotations provided, the description carries the full burden. It doesn't disclose that the operation is irreversible, whether it requires document save, or if it works across the entire document only. Given no annotations, a 3 is reasonable as it provides some behavioral context but lacks depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
