Can I use the Google Stitch and DESIGN.md DESIGN.md with Cursor, Claude Code, or Codex?

Yes. Copy the DESIGN.md file into your project root and reference it in your agent rules. For Cursor, add it to .cursor/rules. For Claude Code, include it as CLAUDE.md. For Codex, add it to your system prompt. The agent will read it and apply the Google Stitch and DESIGN.md visual system to any UI it generates.

What is a DESIGN.md file?

A DESIGN.md file is a Markdown document that describes a product's visual design system — color palettes, typography, spacing, and component patterns — in a format that AI coding agents like Cursor, Claude Code, and Codex can read and follow when generating UI.

How do I add the Google Stitch and DESIGN.md DESIGN.md to my project?

Download or copy the DESIGN.md file from this page and place it in your project root. Then instruct your AI agent: "Read the DESIGN.md file in this project and follow its design system when generating UI." The agent will pick it up automatically in Cursor, Claude Code, Codex, and most modern AI coding tools.

Design System Overview

The Google Stitch and design system captures the visual language of a well-known developer tools and IDEs product. This DESIGN.md file distills its color palette, typography, spacing scale, and component patterns into a format that AI coding agents can read and follow when generating UI.

Why Stitch made design memory a real product pattern.

AI agents like Cursor, Claude Code, Codex, and Google Stitch can reference this file to produce UI that visually matches the Google Stitch and aesthetic — consistent colors, proportional spacing, and recognizable component patterns — without requiring explicit pixel-by-pixel instructions for every element.

Use with AI Coding Agents

Copy one of these prompts into your AI coding agent to apply the Google Stitch and DESIGN.md design system to your project. The DESIGN.md file in your repo root is the source of truth.

# .cursor/rules (or DESIGN.md)
You are working in a project that uses the Google Stitch and DESIGN.md design system.

Read the DESIGN.md file in this project root and follow it strictly when generating UI.
Match the brand's exact colors, typography, spacing scale, and border radius.
Do not create generic Tailwind UI — apply the visual language from DESIGN.md.

Key rules:
- Use the defined color palette, not arbitrary hex values
- Apply the correct font family and weight scale
- Follow spacing tokens (4/8/12/16/24/32px scale)
- Match component patterns: buttons, cards, inputs, badges as specified
