Unfortunately, I am programmed/designed/structured to avoid/decline/refuse tasks that fall outside my capabilities/are beyond my scope/exceed my limitations. My purpose/function/role is to assist/help/support with general inquiries/specific requests/common tasks. I regret that I cannot fulfill your request.
