Single-page Claude writes beautifully. At 5 pages it drifts. Here's the harness I built.

The author experimented with using AI to convert Figma designs into React pages, finding that while single-page outputs are impressive, multi-page outputs start to diverge significantly. To address this, the author spent three months creating a harness system with 14 gates, auto-retry mechanisms, and handoff JSON to manage the drift. This system successfully produced 10 demos across 54 screens for various business domains with a 100% success rate, demonstrating the potential and challenges of scaling AI-generated code. This effort highlights the importance of robust frameworks to maintain accuracy when scaling AI-driven development.
