DESIGN.md Generator for Agent-Friendly Product Specs

Generate DESIGN.md files that document tokens, components, UX rules, and implementation expectations for coding agents and teams.

Quick orientation

When to use this tool

Use this generator when you need a product or UI brief that coding agents can actually follow without turning every design decision into guesswork.

  • 1

    When handing a feature to a coding agent or new teammate

  • 2

    When your UI rules live in scattered tickets and Slack messages

  • 3

    When you want a reusable first draft of project conventions

AI shortcut

Generate a first draft from a product description

This works best when you describe the product, the audience, and the visual mood you want. Treat the AI output as a draft to refine, not the final design system.

What a useful DESIGN.md does

A good DESIGN.md cuts ambiguity. It tells humans and agents what matters about spacing, tone, components, edge cases, and constraints before implementation starts drifting.

This tool helps you get to that draft faster so the real work can start from a shared baseline.

Common mistakes

What usually weakens a DESIGN.md

The file should reduce ambiguity for builders. If it only lists pretty colors and vague aspirations, it does not do the job.

Documenting tokens without explaining how they should be used in real components.
Leaving spacing and typography too generic, which forces the implementation to guess the hierarchy.
Treating AI output as final instead of checking whether the system matches the product reality.
Forgetting that coding agents need constraints and examples more than abstract taste statements.

FAQ

Is this only for design systems?

No. It also helps for smaller products or features where you want clear implementation rules without writing a massive spec.
