What is the Superdesign skill?

The Superdesign skill (a design skill, or UI skill, for coding agents) is an AI product design agent you run from inside Claude Code, Cursor, Windsurf and other agentic tools. After a quick CLI install you invoke it with a prompt such as help me design a pricing page, and it generates and iterates real UI designs on an infinite canvas, using the full context of your codebase, then hands a design prompt back to your agent to implement the code. It is the same design agent as the Superdesign web app, just delivered inside your coding workflow instead of the browser.

A quick tour of designing UI from inside your coding agent with the Superdesign skill.

How it works

Install the CLI

One npm command, globally.

Log in

Authorize the CLI through your browser.

Add the skill to your agent

Add it at project level (creates an agents folder in your project) or globally across every project.

Prompt from your agent, iterate on the canvas

Ask your agent to design something, then refine on the infinite canvas and send the design prompt back to ship the code.

Install in your agent

Same skill everywhere. Pick your coding agent for the exact setup.

Zero extra config. Once the skill is added, Claude Code picks it up as a slash command straight away.

1. Add the skill

2. Use it

That's it. Ask it to set a design system, improve an existing screen, or design a whole flow, all from your terminal.

What you can build

Dashboards & data UI →

Charts, tables, filters and layouts that actually hold together, generated and refined in a few prompts.

Landing pages →

Hero, sections, pricing and CTAs designed as a coherent page, not a pile of disconnected blocks.

Components →

Buttons, cards, modals and nav with real states and animation, matched to your design system.

Full flows →

Multi-page flows like onboarding or schedule-a-demo, designed as functional pages with clickable elements.

It knows your codebase

On a new project it drafts clear requirements and a style guide. On an existing one it analyzes your current UI and creates a superdesign folder with a design-system file and replica HTML of your pages, so every new design builds on top of what you already have.

It's an interactive process

The agent asks clarifying questions, proposes multiple options for banners, cards and layouts, and iterates on your feedback instead of dumping one take and calling it done.

Flows, not just screens

It designs entire flows like onboarding or schedule-a-demo as multiple functional pages with interactive, clickable elements, not isolated mockups.

Design to shipped code

Copy the design prompt from Superdesign, hand it to your coding agent, and it fetches the design context and plans the build. Multi-select pages to generate one comprehensive implementation prompt.

Matches your brand

Pin your logos, fonts and colors, or pull a brand guide straight from any live URL, so every design comes out on-brand instead of in a generic template look.

Explore directions in parallel

Branch a design into several directions at once and keep the one that works, instead of re-prompting a blind model and re-rendering by hand to compare.

Edit on the canvas, undo anything

Click, drag, resize and restyle any element directly on the canvas without writing a prompt, with full version history to roll back any frame.

Start from any live page

Clone a full page or a single component from any live website into your canvas with the Chrome extension, then redesign from there.

Not sure which direction to take? Browse the design styles encyclopedia for ready-made looks like glassmorphism, brutalism and neumorphism, then generate any of them as a design skill inside Claude Code or Cursor.

Skill vs web app vs designing by hand

All three get you to a UI. Here is the honest trade-off, so you can pick the one that fits how you work.

	Superdesign skill	Superdesign web app	Designing by hand
Where it runs	Inside your coding agent	In your browser	In a design tool
Setup	One CLI install	None, just sign in	Learn the tool
Iteration speed	Fastest, you never leave flow	Fast, visual canvas	Slowest, manual
Codebase context	Reads your existing code	Prompt-driven	You hold it in your head
Handoff to code	Design prompt straight to your agent	Copy prompt to your agent	Manual spec / redlines
Best for	Devs shipping UI in their workflow	Trying it with nothing installed	Full pixel control

The reason so many power users live in the skill: it stays in your coding workflow, so the loop from idea to iterated design to shipped code never breaks. If you would rather not install anything, the web app runs the exact same agent.

Frequently asked questions

How do I install the Superdesign skill?

Three commands. Install the CLI with npm install -g @superdesign/cli@latest, authorize with superdesign login, then add the skill to your coding agent with npx skills add superdesigndev/superdesign-skill. You can add it at project level (creates an agents folder in that project) or globally (available across all your projects).

Can Claude Code design UI?

Yes. With the Superdesign skill added, Claude Code designs UI directly through a slash command: /superdesign help me design a pricing page. It generates and iterates on real UI designs on an infinite canvas without you leaving your terminal.

What's the best design agent for Cursor?

Superdesign is a design agent built for exactly this. In Cursor you register it once under Settings, Rules and Commands as a command named superdesign, then invoke it with /superdesign like any other command.

What's the best design skill for Claude Code?

For UI and product design, Superdesign is purpose-built for it. Most Claude Code skills wrap a prompt; Superdesign runs a full design agent that reads your codebase, generates and iterates real UI on an infinite canvas, and hands a design prompt back to Claude Code to implement. Add it with npx skills add superdesigndev/superdesign-skill and design with /superdesign help me design X.

Is Superdesign a Figma alternative?

For the design-to-code workflow, yes. Instead of drawing static frames in Figma and handing them off, Superdesign generates and iterates real UI from inside your coding agent, then passes a design prompt straight to Claude Code or Cursor to build it. You skip the manual redraw-then-redline loop and go from idea to shipped UI in one flow.

Does the Superdesign skill work with Claude Code and Cursor?

Both, plus Windsurf and other coding agents. The same skill installs everywhere via npx skills add superdesigndev/superdesign-skill. Claude Code works with zero extra config, Cursor needs a one-time command setup, and the workflow stays consistent across agents.

Is the Superdesign skill free?

The CLI and skill are free to install and the open-source roots are public. You bring your Superdesign account for generation. If you would rather not install anything, the web app gives you the same design agent in the browser.

What's the difference between the Superdesign skill and the web app?

Same design agent, two ways in. The skill lives inside your coding agent so you never break flow and iteration is fastest, and it can read your existing codebase for context. The web app runs the same agent on a visual canvas in your browser with nothing to install. Most power users live in the skill because it stays in their workflow.

How do I design UI without leaving my coding agent?

Add the Superdesign skill, then just ask your agent: help me design X, set a design system, or improve the design of X. It generates designs on an infinite canvas, iterates on your feedback, and hands a design prompt back to your agent to implement the code, all without switching tools.

Design without leaving your agent

Install the Superdesign skill and start designing UI from Claude Code, Cursor or Windsurf in under a minute.
