Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It does disclose the main effect (returning to the main menu) and the prerequisite relationship to omni_world_create. However, it does not clarify side effects, whether the operation is safe/idempotent when no world is active, or what happens to the current world state.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
