How to Wire DESIGN.md into Claude Code, Cursor, Kiro and Windsurf

A developer shows how to wire a DESIGN.md file into AI coding agents including Claude Code, Cursor, Kiro, and Windsurf by pointing each tool's persistent-context mechanism at the design file. The same DESIGN.md serves all tools simultaneously, preventing design drift. The approach works by referencing DESIGN.md from CLAUDE.md or using a rules file to inject design context into every UI generation.

To make an agent use DESIGN.md, point its persistent-context mechanism at the file. The pattern is the same everywhere: tell the agent to read DESIGN.md for UI work. Reference DESIGN.md from your CLAUDE.md: In CLAUDE.md Design This project has a DESIGN.md defining the visual identity. Before generating or modifying any UI, read DESIGN.md and follow its tokens and rationale. Use the accent color only as the rationale specifies. Use a rules file to inject DESIGN.md into every UI generation, so the design context is present whenever the agent produces interface code. php Kiro - add DESIGN.md to the steering directory Windsurf - point the global rules file at DESIGN.md Every agent has a persistent-context mechanism; you route it to your design file. Ask the agent to generate a component and inspect the result: The first generation usually reveals a gap in your prose. Fill it, and the fix is permanent. Because DESIGN.md is an open format, the same file serves Claude Code, Cursor, Kiro and Windsurf at once - one design source of truth, no per-tool drift. Where do DESIGN.md files come from? Write one by hand, generate a draft with an agent, or export from Google Stitch. Does it work across tools? Yes - one file, read by each tool's own mechanism. Wiring in DESIGN.md is always the same move: tell the agent's context mechanism to read the design file for UI work.
