Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations are absent, so the description carries the transparency burden. It adds useful behavioral details: '智能插入到正确位置' (intelligently inserts into the correct position) and '避免重复' (avoids duplicates). However, it does not disclose edit effects, permission requirements, or behavior when the category already exists beyond duplicate avoidance.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
