Zypsy's product design skill is a free, MIT-licensed design system for AI agents. It teaches Claude Code, Cursor and any agent that supports skills to think about product design the way we do. We're a design and investment firm, and we built it from a decade of shipping product for funded startups and global brands. It's on GitHub, free for anyone to use.

What the skill covers

  • Information architecture
  • Interaction patterns
  • Visual design
  • Design systems
  • AI-native UX

The skill isn't a style guide. It's an operating system for design decisions.

Why AI-generated UI looks generic

Most AI-generated UI looks like AI-generated UI. Generic, safe, forgettable. That's a tooling problem, not a model problem. The models are capable. They just don't know what good looks like unless you teach them.

How the skill handles empty states and forms

Take empty states. Most AI tools treat them as an afterthought: a centered icon, a headline, a button. But an empty state is where someone decides whether the thing is worth their time. Our skill treats it as an onboarding moment, not a placeholder.

Or take forms. Most AI output stacks every field with equal weight and throws away your input when something fails. Our skill shows only what's needed to finish the task, keeps labels visible instead of hiding them in placeholder text, and never loses a half-completed form on error.

How to install it

Two commands in Claude Code, a remote rule in Cursor, or one line for any other agent. Install instructions are in the README. Or read the skill itself.

Frequently Asked Questions

What is the Zypsy product design skill?

The Zypsy product design skill is a free, open-source behavioral instruction file that teaches AI coding agents how to approach product design systematically. Instead of only generating visuals, it shapes how an agent reasons about UI structure, information hierarchy, component choices, copy, and AI-specific features.

Is the Zypsy product design skill free?

Yes. It's free and open source under the MIT license.

What does the skill cover?

The Zypsy product design skill covers the areas where AI agents most often produce weak design: structural decisions, information hierarchy, state coverage including empty and error states, AI feature design, copy quality, and common anti-patterns. It spans information architecture, interaction patterns, visual design, design systems, and AI-native UX.

How is it different from a style guide?

A style guide describes how things should look. The Zypsy product design skill describes how to decide. It encodes reasoning: what to ask before designing a flow, how to sequence a form, when an empty state carries the product. That makes it portable across brands rather than tied to one visual language.

Who is it for?

The Zypsy product design skill is built for developers shipping their own products, designers working in AI coding tools, and design-aware founders who want structurally sound output instead of generic AI patterns. It assumes you are building real product, not prototyping throwaway screens.

Which AI tools does it work with?

Claude Code, Cursor, and any agent that supports skills.

How do I install the Zypsy product design skill?

In Claude Code, run /plugin marketplace add zypsycom/product-design-skills then /plugin install. In Cursor, add a Remote Rule pointing to the repo under Settings, then Rules & Command, then Project Rules. For any other agent, run npx skills add zypsycom/product-design-skills. No API key or configuration is required.

Will it replace a product designer?

No. It isn't meant to replace a designer on complex products. It raises the quality of what AI agents produce. If your team needs designers in the loop, not just agents, that's what we do.
