design.md

free

DESIGN.md is a format specification from Google Labs for describing a visual identity to coding agents. It pairs machine-readable design tokens (YAML front matter) with human-readable design rationale (Markdown prose), giving agents a persistent, structured understanding of your design system. Ships with an official CLI (@google/design.md) for linting (WCAG contrast, broken refs), diffing, and exporting to Tailwind v3/v4 or DTCG. Still in alpha.

AGENTS.md is an open format standard for documenting instructions that AI coding agents need to work on software projects. Think of it as a README for agents: a dedicated, predictable place for setup commands, code style, testing instructions, and project conventions. Stewarded by the Agentic AI Foundation under the Linux Foundation, it is used by 60,000+ open-source projects.
