Pattern: DESIGN.md Becomes Standard Context-Engineering Interface Between Designers and Coding Agents

GitHub / Google Stitch·medium signal

Google Stitch generates DESIGN.md files alongside its UI designs; awesome-design-md hit 71K stars packaging 57 brand systems in this format; Claude Code skills marketplaces list DESIGN.md loaders. The pattern: a structured markdown file describing colors, typography, spacing, and component patterns serves as persistent agent context for UI generation. This is context engineering applied to design — the same file works for Claude Code, Cursor, Codex, and any MCP-compatible agent.
