UI Craft

Ship designer-grade UI by default. A design engineering system for AI coding agents — install it as a skill or as the ui-craft CLI, and your agent starts designing like it has taste. Ask for a dashboard, get one you'd put in production. Not gradient cards and bounce animations.

Website: skills.smoothui.dev

Ask for a surface. Ship it.

/craft dashboard

Three questions (or none — the defaults are strong), a named composition, a production theme preset, and a build that must pass a 10-item acceptance bar before it reports done: "would a designer retouch this?" If a box fails, it isn't done.

For everything else — reviews, animations, forms, polish — the skill routes by intent: just describe what you're building.

New here? Run /start — it reads your project (framework, tokens, brief, existing UI) and tells you what ui-craft can do right now, then points you at the right next step.

What it does

UI Craft gives AI coding agents the design knowledge they're missing. Not templates. Not component libraries. Actual craft knowledge — opinionated rules about how interfaces should look, move, and feel — plus the tooling to verify the result. Stack-agnostic by design.

Every UI gets tested against a single question: "Would someone believe AI made this?" If yes, it starts over.

The ladder — four rungs

There is one thing to learn, and it's a ladder. Each rung is a real jump in what you get, and each costs a little more than the one below. You only climb when you want the next thing.

Rung	You want	You do	You get	Effort
0 · Ask	Better UI with zero effort	Install, then ask for UI the way you always do	Real hierarchy, your own tokens, no AI slop — same prompt, shippable result	none
1 · Direct	Control over one pass	/craft, /critique, /polish, /animate, …	A focused pass on one surface, aimed by you	one command
2 · Persist	Consistency across sessions	/brief, /tokens, /remember	Durable design context every future session reads	write once
3 · Enforce	Proof it cannot regress	/finalize, review agents, MCP gates, ui-craft-detect	Gates in review and CI, plus a deterministic 0-100 score	wire once

Start at rung 0. Most people never leave it — that's the point. Rungs 1 to 3 are there the day you want them, and /start will tell you which rung your project is on right now.

/sddesign is not a fifth rung. It's the express lane that walks rungs 1 to 3 in one guided run, for a single big surface.

What makes this different: the only AI design system that produces a scoreable, defensible critique — Nielsen's 10 usability heuristics × 6 classic design laws (Fitts, Hick, Doherty, Cleveland-McGill, Miller, Tesler) × 5 persona walkthroughs, with every finding tagged by business impact (blocks-conversion / adds-friction / reduces-trust / minor-polish). Paste the scorecard straight into any issue tracker.
