DESIGN.md: Single file standardizes brand design for agents
The article explains DESIGN.md, a proposed plain-text standard that combines machine-readable design tokens (YAML frontmatter) with human-readable rationale (Markdown) in one file. Google Labs open-sourced the DESIGN.md format in April 2026 and provides examples and command-line tooling to lint, diff, and export tokens. The format defines eight ordered sections (Overview, Colors, Typography, Layout, Elevation & Depth, Shapes, Components, Do’s and Don’ts) and treats tokens as normative while prose provides intent. The file is intended to live in the code repository (e.g., beside README.md) so both humans and AI agents can read the brand’s source of truth, reducing agents’ reliance on generic components and improving design-to-code workflows.
