THE BOX DESIGN SYSTEM: AI‑READY FIGMA FILES FOR ENTERPRISE SOFTWARE

Summary from the TLDR Design newsletter

Flexy Global's Box Design System organizes complex enterprise product behavior into bounded Figma sections, making design files easier for people to navigate and for AI coding agents to use. Boxes form a feature, flow, and screen-state hierarchy built around behavior rather than pages, with self-contained context and arrows showing transitions. They cannot fix an undefined product or replace the design system and codebase, but as design files become inputs to AI-assisted development, this structure is becoming part of the product.
