What problem this solves

Demonstrating Claude Code's ability to autonomously plan, orchestrate multiple agents, and generate a complex, functional game (Mario Kart clone) from a single high-level prompt.

Summary

A single-prompt workflow leveraging Claude Code's internal multi-agent capabilities (Sonnet 5.5 High) to generate a complete, playable Mario Kart clone using 3JS, including multiple tracks, racers, items, and game modes.

Why it is useful

This workflow is highly valuable as it demonstrates an advanced capability of Claude Code: the ability to autonomously orchestrate multiple sub-agents (implied by the prompt) to plan, execute, and deliver a complex, functional software project (a Mario Kart clone) from a single, high-level prompt. It provides concrete metrics and a live playable demo, making it a powerful proof-of-concept for complex code generation and project management using LLMs. It highlights the potential for 'one-shot' development of significant applications.

Workflow

1. Prepare an empty directory for the project.
2. Provide the specified prompt to Claude Code, instructing it to launch five Sonnet 5.5 sub-agents and build a Mario Kart clone using 3JS without further interaction.
3. Allow Claude Code to execute the task, orchestrating the lead and builder agents over approximately 67 minutes.
4. Review the generated code and test the resulting game via the provided link.

Tools / artifacts

• Claude Code (with Sonnet 5.5 High)
• Prompt for multi-agent game generation
• 3JS (as the target library for game development)
• Generated Javascript game code
• Playable game (Turbo Karts)

Validation signals

• Detailed metrics: 67 min build time, 424 model calls, 889k tokens written, 78M tokens read, $29.28 API cost.
• Specific output: 11,400 lines of Javascript, 4 tracks, 8 racers, 10 items, drift boosts, bots, grand prix, skirmish mode.
• Live playable demo link provided: https://ohmygames.app/play/turbo-karts

Limitations

• High API cost ($29.28 for a single run).
• The generated game lacks images and sound files, making it purely code-based and visually basic.
• The exact mechanism of Claude Code 'launching sub-agents' is implied by the prompt rather than explicitly detailed as a user-configurable setup (e.g., via MCP).
