Partial The dual-agent arena and scenario demo are vibe-codeable, but live ordering depends on access to a restricted McDonald's China API that a solo builder cannot obtain without a partnership.
What it would actually take: The demo layer is straightforward agent orchestration with a UI. Live use requires authorized API credentials, schema mapping against a proprietary ordering system, and handling of payments and real-world order failures, which depend on the partner's access and cooperation rather than engineering alone.
