A Claude Code plugin that helps you make confident UI design decisions through rapid iteration.

Design and Refine generates multiple distinct UI variations for any component or page, lets you compare them side-by-side in your browser, collects your feedback on what you like about each, and synthesizes a refined version—repeating until you're confident in the result.

Instead of guessing at the right design or going back-and-forth on revisions, you see real options, pick what works, and iterate quickly.

• Starting a new component or page — explore different approaches before committing
• Redesigning existing UI — see alternatives to what you have today
• Stuck on a design direction — generate options when you're not sure what you want
• Getting stakeholder buy-in — show concrete variations instead of describing ideas
• Learning what works — see how different layouts, densities, and patterns feel in your actual codebase

1. Uses your existing design system — infers colors, typography, spacing from your Tailwind config, CSS variables, or component library
2. Generates real code — not mockups, actual working components in your framework
3. Side-by-side comparison — view all variations at /__design_lab in your dev server
4. Iterative refinement — tell it what you like about each, get a synthesized version
5. Clean handoff — outputs DESIGN_PLAN.md with implementation steps when you're done
6. No mess left behind — automatically cleans up all temporary files

In Claude Code, run:

/plugin marketplace add 0xdesign/design-plugin

/plugin install design-and-refine@design-plugins

That's it. The plugin is now available in any project.

/design-and-refine:start

Or with a specific target:

/design-and-refine:start ProfileCard

1. Preflight — detects your framework (Next.js, Vite, etc.) and styling system (Tailwind, MUI, etc.)

2. Style inference — reads your existing design tokens from Tailwind config, CSS variables, or theme files

3. Interview — asks about:

   • What you're designing (component vs page, new vs redesign)
   • Pain points and what should improve
   • Visual and interaction inspiration
   • Target user and key tasks

4. Generation — creates 5 distinct variations exploring different:

   • Information hierarchy
   • Layout models (cards, lists, tables, split-pane)
   • Density (compact vs spacious)
   • Interaction patterns (modal, inline, drawer)
   • Visual expression

5. Review — open http://localhost:3000/__design_lab (or your dev server port) to see all variations side-by-side

6. Feedback — tell Claude:

   • If one is already good → select it, make minor tweaks
   • If you like parts of different ones → describe what you like about each, get a synthesized version

7. Iterate — repeat until you're confident

8. Finalize — all temp files are deleted, DESIGN_PLAN.md is generated with implementation steps

/design-and-refine:cleanup

• Next.js (App Router & Pages Router)
• Vite (React, Vue)
• Remix
• Astro
• Create React App

• Tailwind CSS
• CSS Modules
• Material UI (MUI)
• Chakra UI
• Ant Design
• styled-components
• Emotion

Be specific in the interview. The more context you give about pain points, target users, and inspiration, the more distinct and useful the variations will be.

Reference products you admire. "Like Linear's density" or "Stripe's clarity" gives Claude concrete direction.

Don't settle on round one. The synthesis step is where it gets good—describe what you like about each variant and let it combine them.

Keep your dev server running. The plugin won't start it for you (that would block). Just have it running in another terminal.

Check the DESIGN_PLAN.md. After finalizing, this file contains the implementation steps, component API, accessibility checklist, and testing guidance.

During the session:

• .claude-design/ — variants, previews, design brief
• app/__design_lab/ or pages/__design_lab.tsx — the comparison route

All of this is deleted when you finalize or abort. Nothing is left behind.

After finalizing:

• DESIGN_PLAN.md — implementation plan for your chosen design
• DESIGN_MEMORY.md — captured style decisions (speeds up future sessions)
