What do people build with it?

USE CASE 1

Build consistent dashboards by having Claude remember your spacing and color choices across multiple coding sessions.

USE CASE 2

Audit existing AI-generated UI code to find components that don't match your saved design system.

USE CASE 3

Extract design patterns from code you've already written and save them as reusable tokens for future sessions.

USE CASE 4

Have Claude infer a design direction from your project context and apply it automatically before building new screens.

So what is it?

Interface Design is a plugin for Claude Code, the AI coding assistant, that brings structure and memory to UI building. When you ask Claude to build a dashboard, an app, or an admin panel, design choices get made on the fly: spacing values, colors, depth treatment, button sizes. Without a system in place, those choices drift between sessions, leaving inconsistent interfaces where buttons are 36px in one place and 40px in another. This plugin addresses that by giving Claude a set of design principles to follow and a persistent memory file. Your decisions get saved to a file called .interface-design/system.md in your project, things like your spacing base, color tokens, and component patterns. At the start of each session, Claude loads that file and applies the same established patterns automatically, so a settings page built in week two matches the dashboard built in week one. The plugin also adds commands you can run inside Claude Code: /interface-design:init starts a new design session, /interface-design:status shows the current system, /interface-design:audit checks existing code against the system, and /interface-design:extract pulls patterns out of code you have already written. When starting fresh, Claude infers a design direction from your project context, choosing between directions like Precision & Density for developer tools, Warmth & Approachability for consumer apps, or Data & Analysis for analytics dashboards, then asks for confirmation before applying it. It is scoped to functional interface design: dashboards, apps, tools, and admin panels. It explicitly does not target marketing sites. Written primarily in Shell. Licensed under MIT.

Copy-paste prompts

Prompt 1

I am using the interface-design Claude Code plugin. Run /interface-design:init for my developer tool project and apply the Precision and Density design direction.

Prompt 2

Run /interface-design:audit on my codebase and list every component that violates the spacing or color rules saved in .interface-design/system.md.

Prompt 3

Use /interface-design:extract to pull button sizing and color token patterns from my existing components and add them to the design system file.

Prompt 4

Build me a settings page using Claude Code with the interface-design plugin active, making sure it matches the design system already established for my dashboard.

Prompt 5

My project is a consumer app. Run /interface-design:init with the Warmth and Approachability direction and then show me the full system with /interface-design:status.
