UI-stack – Claude skill that enforces design system on AI-generated UI
The problem with AI-generated frontend code is that without constraints, every generation picks different spacing, colors, and patterns. The 50th component looks nothing like the first. ui-stack is a Claude Code skill — a set of structured reference files that Claude reads when building UI. It's built for Next.js + Tailwind + Shadcn but the principles are framework-agnostic. What's interesting about the "skill" approach vs. a system prompt: the reference is modular and file-based, so you can update one file (say, colors.md) and the change propagates everywhere. There's also a browser-based config dashboard so you can customize your brand palette and font before the skill activates. Would love feedback — especially from anyone who's tried to enforce design consistency across a large Claude Code project.

✨ AI Summary
UI-stack is a Claude Code skill that enforces a design system on AI-generated frontend code by providing structured reference files. It is built for Next.js, Tailwind, and Shadcn, but its modular, file-based approach is framework-agnostic.
Best For
Frontend developers using Claude Code for UI generation, Teams building large projects with AI-generated components, Developers seeking design consistency across multiple AI-generated UIs
Why It Matters
It ensures design consistency in AI-generated UI by using modular reference files that can be updated centrally, preventing visual drift across components.
Key Features
- Enforces design system consistency across AI-generated UI components
- Provides modular file-based reference system for design constraints
- Includes browser-based config dashboard for brand customization
- Built for Next.js, Tailwind, and Shadcn frameworks
Use Cases
- A startup founder uses Claude to rapidly prototype their SaaS dashboard. Without UI-stack, each new feature request results in inconsistent button styles and spacing. With the skill activated, every generated component maintains the brand's color palette and typography scale, allowing the founder to present a polished MVP to investors.
- A freelance developer maintains multiple client projects where each uses Claude for component generation. Previously, updating a client's brand colors meant manually editing dozens of generated files. Now, they simply modify the colors.md reference file once, and all future Claude-generated components automatically reflect the new palette.
- A design system lead at a mid-sized tech company struggles with engineers using AI tools that bypass established patterns. They configure UI-stack's dashboard with approved spacing tokens and component variants, ensuring that even AI-assisted development adheres to the company's design guidelines.
