Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description does not add behavioral context beyond what annotations already provide. It simply states the action. No mention of irreversibility, effects on scene items, or error conditions. Since annotations already declare destructiveHint=true and idempotentHint=true, the description adds no extra context, but it doesn't contradict either.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
