BUILDING AN AI-READY DESIGN SYSTEM LIBRARY: CODE → FIGMA WITH MCP. HANDS-ON GUIDE

Summary from the TLDR Design newsletter

Figma captures only part of the behavior encoded in production components, leaving AI to invent missing details such as focus order, error states, accessibility behavior, and failure handling when translating designs directly into code. Reversing the workflow makes code the source of truth and Figma its visual mirror, with AI and MCP transferring real tokens, styles, properties, variants, and states from a repository into a usable design library. Storybook provides designers with a visual view of the production system, while explicit documentation of anything that cannot be represented in Figma helps maintain parity instead of allowing invisible differences to accumulate.
