Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, which communicates the write nature and safety. The description adds that the operation uses POST, but it does not disclose additional behavioral details such as permissions required, side effects, or reversibility. With annotations covering the core safety profile, this is acceptable but not enriched.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
