How our agents build on-brand pages with design.md

Summary

Vercel described how its coding agents build on-brand pages using a design.md file, a skill it calls product-design that encodes the typography, color, and composition judgment used on its own shipped pages.

Key facts

• Vercel uses coding agents to design and build pages that match its brand.
• The approach relies on a design.md file.
• Vercel calls the skill product-design.
• The skill covers typography, color, and composition.

Why it matters

Teams that want agent-generated pages to match an existing brand may need to encode their design rules in a written spec rather than rely on the model's defaults.
