Shipping in Half a Day: How AI Agents Split Roles Like a Real Team

This project showcases a novel development workflow where AI agents divide responsibilities—Claude Code handles product management and code review while Codex implements—eliminating the self-confirmation bias of single-model development. By shipping a fully functional, payment-enabled web app in half a day, it demonstrates the unprecedented speed AI collaboration can achieve in the development cycle. The architecture choice to process sensitive health data entirely in-browser highlights how AI-assisted development can incorporate privacy-first design principles.
