Notes from the system layer
Practical writing on design systems, component APIs, and the details that keep product UI consistent across Figma and React.
How to Connect Claude Code to Figma
Connect Claude Code to your Figma designs via AI Bridge. Read components, extract design tokens, generate production CSS with var() references — not hardcoded pixels.
How to Connect Cursor to Figma
Connect Cursor editor to Figma via AI Bridge plugin. Read design tokens, component structure, and generate production CSS — all from your editor.
How to Connect OpenAI Codex to Figma
Connect OpenAI Codex to Figma through AI Bridge. Expose the local Bridge API via tunnel so Codex's cloud sandbox can read designs and tokens.
Figma to React with AI: Complete Guide
Convert Figma designs to production React code using AI. Token-aware approach that preserves design variables instead of hardcoding pixel values.
Why AI-Generated CSS Breaks in Dark Mode
AI tools hardcode hex colors instead of using design tokens. Dark mode exposes the problem instantly. Here is how to fix it.
Design Tokens: What AI Code Editors Get Wrong
AI editors write valid CSS but miss design intent. Here is how design tokens get lost in translation and what to do about it.
Figma MCP vs Figma AI Bridge: What's the Difference
Figma MCPs read structure and raw values. AI Bridge reads and writes design token bindings. Here's when to use each — and when you need both.
Best React Component Libraries in 2026
A practical comparison of the best React component libraries in 2026 — features, trade-offs, and how to pick the right one for your project.
Best Figma Plugins for AI Code Generation
A fair comparison of Figma plugins that connect AI code editors to design files — from free MCPs to full read-write bridges.
Do Startups Need a Design System?
Startups think they are too early for a design system. With AI writing UI code faster than ever, you are too early to skip one.
Figma AI Bridge: Design Tokens, Not Just Pixels
Standard Figma MCPs return raw hex and pixel values. AI Bridge returns actual design token bindings — the difference between hardcoded CSS and production-ready code.
Why 9 Button Sizes, Not 4
Four button sizes are fine for demos. Real products need a broader, unified size scale across controls.
Why Your AI Code Editor Needs a Design System
AI code editors ship UI faster, but without a design system they also ship inconsistency. Here is how to keep quality high.
