This article presents a brilliantly innovative approach to autonomous software development by structuring multiple Large Language Models (LLMs) into a checks-and-balances system. By utilizing Claude, GPT, and Gemini as a Writer, Critic, and Judge respectively, the author has successfully automated the tedious aspects of coding. It is a fantastic showcase of how multi-agent architectures can unlock true automation and completely eliminate human bottlenecks in the development pipeline.
Key Takeaways
- •A multi-agent "Trias Politica" loop was built using n8n to completely automate code generation, review, and testing.
- •Different models are assigned distinct roles: Claude acts as the Writer, GPT as the Critic, and Gemini as the Judge.
- •The Judge agent runs the code in an E2B sandbox to physically verify execution, looping back to the Writer if it scores below 70 points.
