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 clearly states the state transition (exiting game mode and entering edit mode) and is honest about the operation's effect. It does not detail edge cases like calling it while already in edit mode, but for a parameterless mode toggle this is adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
