"My Two AI Tasks Kept Fighting for the Same Mouse"

A local AI assistant was experiencing issues with multiple tasks competing for the same physical resources (mouse, keyboard, and screen) on a Windows desktop. This was due to a shallow mental model that treated all tasks as equally parallel. By introducing a separate truth about resource ownership and waiters, the AI assistant can now serialize tasks that need the same exclusive resource and run them in parallel otherwise. This change has improved the assistant's behavior, making it more like a human assistant.
