Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It says "delete" but never states that data is destroyed, whether the action is reversible, whether it requires a case/analysis to be active, or what the option values mean. For a destructive mutation this is a serious gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
