Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It explicitly states the significant side effect 'Removes all its scene items too', which is critical for a destructive operation. However, it does not mention reversibility, permissions, or error behavior, so it is not fully transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
