Google Stitch and DESIGN.md
How Google Stitch popularized DESIGN.md as a design-system format for AI UI generation.
The pattern
Stitch uses DESIGN.md as a way to preserve visual identity across AI-generated UI. The file acts like an instruction layer for taste, not just a token dump.
Beyond Stitch
The same idea works for code agents. A repo can pair AGENTS.md for engineering behavior with DESIGN.md for visual behavior.
Catalog opportunity
Because the ecosystem is early, a curated directory helps people find working examples faster than searching generic web results.
