What is CLAUDE.md?
CLAUDE.md is a markdown file that gives AI coding assistants context about your brand. Colors, fonts, component patterns — so every AI-generated component is on-brand.
Definition
CLAUDE.md is a markdown file placed in a project's root directory that provides brand context to AI coding assistants like Cursor, Claude, and GitHub Copilot. It contains design rules, color values, component patterns, and style guidelines.
How it works
When you use an AI assistant to generate a React component, it needs to know your brand colors, preferred font, button style, and spacing conventions. Without this context, every AI-generated component uses random defaults. CLAUDE.md solves this by giving the AI a concise reference document. When Cursor or Claude reads your project, it finds CLAUDE.md and uses it as a style guide for all generated code.
Why it matters
AI-assisted coding is the default in 2026. If your AI assistant doesn't know your brand, you're manually fixing colors and fonts in every generated component. CLAUDE.md turns AI from a brand liability into a brand asset — every component it generates is automatically on-brand.
Example
