Interface Design

Build product interfaces with the craft of a top design team — Linear, Vercel, Stripe, Apple. The difference between those and generic output is not talent. It is that every decision was decided, the hierarchy is unmistakable, and a hundred small details are correct at once. This skill is how you get there.

Scope

Use for: Dashboards, admin panels, SaaS apps, tools, settings pages, data interfaces.

Not for: Landing pages, marketing sites, campaigns, brand-only work. Use a marketing/frontend design skill for those.

This skill is self-contained: direction, visual hierarchy, design-system architecture, and the polish and motion essentials needed to ship production-grade UI all live here.

The Problem

You will generate generic output. Your training has seen thousands of dashboards, and the patterns are strong. You can follow this entire process — explore the domain, name a signature, state your intent — and still produce a template: warm colors on cold structures, friendly fonts on generic layouts.

This happens because intent lives in prose, but code generation pulls from patterns. The gap between them is where defaults win. Process helps, but it doesn't guarantee craft. You have to catch yourself, and you have to know the concrete moves that defaults don't.

The bar: If another AI, given a similar prompt, would produce substantially the same output, you have failed. Not different for its own sake — different because the interface emerged from this user, this task, this world. When you design from defaults, everything looks the same, because defaults are shared.

Where Defaults Hide

Defaults disguise themselves as infrastructure — the parts that feel like they just need to work, not be designed.

• Typography feels like a container. But type isn't holding your design, it is your design. The weight of a headline, the personality of a label, the texture of a paragraph shape how the product feels before anyone reads a word. Reaching for your usual font means you're not designing.
• Navigation feels like scaffolding. But navigation is the product — where you are, where you can go, what matters. A page floating in space is a component demo, not software.
• Data feels like presentation. But a number on screen is not design. What does it mean to the person looking? A progress ring and a stacked label both show "3 of 10" — one tells a story, one fills space.
• Token names feel like implementation detail. But --ink and --parchment evoke a world; --gray-700 and --surface-2 evoke a template. Someone reading only your tokens should guess what product this is.
