Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=false, i.e. this is a mutating operation, yet the description's verb is 'Preview', which implies a read-only dry run. This directly contradicts the annotation, and the description says nothing about permissions, reversibility, or the effect of activation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
