Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the behavioral burden. It conveys that this is a non-building, diagnostic reporting tool ('检查/报告'), but it does not state side effects, permissions, failure behavior, or the exact format of the report. The '是否像' phrase adds useful context that it surveys resemblance rather than guaranteeing functionality.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
