Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, so the description's 'WRITE' adds no new safety information. The description fails to disclose important behavioral details such as whether the body is a full replacement or partial update, what the id refers to, or any side effects. With annotations covering the basic write nature, the description contributes minimally to transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
