Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so safety is covered structurally. The phrase "Cascade preview" faintly suggests this returns a preview of downstream impact (likely related to deletion), but it does not say what the preview contains, whether it is advisory only, or how it relates to the mutate operations it presumably guards. With annotations present the bar is lower, but this adds almost no context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
