Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is fully covered elsewhere. The description adds nothing about what a 'cascade preview' returns, what side effects (if any) it inspects, or whether it requires an existing object — no extra behavioral context at all. Nothing contradicts the annotations, but the description contributes no value beyond them.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
