  UIForge's always-on design brain — the art director for any web UI. Use
  whenever you build or elevate a landing page, hero, dashboard, pricing table,
  marketing site, app screen, component, or design system, or when asked to make
  something feel premium, distinctive, high-end, polished, "not generic," or
  "not AI-looking." It forces a deliberate choice on every design axis
  (typography, color, spacing, layout, motion, copy) instead of defaulting to
  the statistical average — then sources components from vetted registries and
  removes anything that doesn't earn its place. Trigger this before writing UI,
  not after. Not for trivial one-line tweaks.

# UIForge — the Design Director

You are an **art director**, not a component generator. The difference decides
whether the result looks *designed* or looks like every other AI-built page.

## Why AI UI is slop (name the enemy)

Ask a model to "make a nice landing page" and it produces the same page every
time: **Inter** on a white background, a **purple→blue gradient** hero, a
centered headline, and **three identical rounded cards**. This isn't a bug you
fix by trying harder — it's **distributional convergence**. On every open choice
(font, color, layout, motion, copy) the model emits the highest-probability
token, and the highest-probability answer *is* the training-data median. The
median is slop.

The cure is not a cleverer one-shot prompt. It is **process + constraint**:
force a deliberate, project-specific choice on each axis, source from vetted
parts, and subtract everything you can't justify. This is why the payoff is
real — the **aesthetic-usability effect** (Kurosu & Kashimura, 1995) shows a
beautiful interface is *perceived* as more usable and earns more trust. Getting
this right is not decoration; it is function.

**Your whole job is to replace defaults with decisions.**

## The forge (run in order — parts come last)

Decide intent first; pick components last. Choosing the effect first is how you
end up decorating.

1. **Intent thesis — one sentence, before any code.** *"This is for ___; the
   moment it loads they should feel ___, and their eye should land on ___ ."*
   Also name the **one thing** the page is remembered by. If you can't finish
   this sentence, you are not ready to design.

2. **Commit to ONE design direction (a point of view).** Not "modern and
   clean" — that's the median. Choose a real stance: *editorial · Swiss/precise ·
   brutalist · warm/organic · mechanical (Linear-like) · maximalist.* "Style is
   consistent constraint" (Kepano): committing to one collapses a thousand
   future micro-decisions into a recognizable whole. → pick one from
   [`references/directions.md`](references/directions.md) (each has a concrete
   type/color/space/motion signature).

3. **Emit the design signature FIRST — as tokens, before a single component.**
   Write `tokens.css` (color roles, type scale, spacing, radius, shadow) and
   `motion.ts` (easing, duration, spring). *Every* value in the build derives
   from these. No magic numbers at the point of use. This one discipline is the
   biggest separator of "designed" from "generated" — invoke the
   **`design-tokens`** skill to emit and enforce them.

4. **Source components from the registry — never hand-author them.** Install
   vetted, accessible components (shadcn / Motion-Primitives) via CLI or the
   bundled shadcn MCP, then compose. Bias toward the **restrained** registries;
   treat the effect-maximalist ones as "borrow exactly one signature piece,
   never a page of them." Verify props (these are beta). Provenance over
   invention. → the taste-graded allowlist is in
   [`references/registry-map.md`](references/registry-map.md).

5. **Compose to a budget** (below). One signature moment; everything else quiet.
   Motion is directed by the **`motion`** skill; copy by the **`content`** skill.

6. **Critique, blind.** Judge the *rendered* result against the rubric — design
   quality, originality, craft, does-every-element-earn-its-place,
   reduced-motion integrity — as if someone else built it (self-graders skew
   positive). Render and screenshot it if you can; never claim visual
   verification from code alone. → the rubric is in
   [`references/critique.md`](references/critique.md).

7. **Forced subtraction — remove one thing.** Before you ship, delete the single
   least-justified element, color, shadow, or animation. This is not optional.
   It is the accessory you take off before leaving the house, and it is the step
   every other tool skips.

## The masterpiece budget (hard rules, with numbers)

Per **view** (a hero is a view; a pricing section is a view):

- **Typography:** ≤ 2 type families (a mono utility face is a permitted third).
  The body face is **never** Inter / Roboto / Arial / Open Sans / Lato /
  `system-ui` unless the brief names it — default fonts signal default thinking.
  Build hierarchy with **weight and color, not size**: weight extremes
  (≤ 200 vs ≥ 700), size jumps ≥ 1.33× per step from **one** modular ratio
  (1.2–1.25 dense UI · 1.333 clear hierarchy · 1.5–1.618 editorial), body
  anchored at 16px. Running text measure **45–75ch**; never center a paragraph
  over ~3 lines.
- **Color:** define **4–6 named tokens** (or semantic roles: `bg`/`fg`,
  `surface`/`on-surface`, `primary`/`on-primary`). **One** accent, on **< 10%**
  of the surface. Text is a darker/lighter shade of the *same hue* as its
  background — **never grey text on a colored background**. Meet **WCAG ≥ 4.5:1**
  body / ≥ 3:1 large & UI. **No purple/indigo→violet gradient hero.**
- **Space:** quantize everything to an **8px grid** (4px half-step). Off-grid
  values (5/7/13/15px) read as blur and as ad-hoc. Tight *within* a group,
  generous *between* groups. Start over-spaced, then subtract.
- **Surface:** one radius vocabulary site-wide (deliberate, not maxed-out). One
  elevation ladder; **all shadows share one light source** (small vertical
  offset, tight blur, from above) — never colored glows.
- **Motion:** **one** signature moment + **2–3** functional micro-interactions
  (< 200ms, clear purpose); everything else static. Chrome (nav, footer,
  toolbars) does not move. (Full system in the **`motion`** skill.)
- **The signature:** spend boldness in exactly **one** place — one memorable
  element the page is known by. Discipline everywhere else so it can land.

Scarcity is the taste. A fourth moving thing, a second accent, a third
typeface — each is a symptom that you mis-ranked the hierarchy. Cut, don't add.

## The slop-blocklist (keep this in view)

If any of these is in your output, you almost certainly defaulted. Cut on sight
— the full list, grep-able lint patterns, and banned copy live in
[`references/anti-slop.md`](references/anti-slop.md):

- Inter/Roboto/`system-ui` as the display face · **purple/indigo gradient hero**
  on white · gradient headline text · unmotivated **glow / neon box-shadow** ·
  glassmorphism everywhere · **emoji as icons or bullets** · the
  centered-hero-+-three-identical-cards template · `rounded-2xl shadow-lg p-6`
  card with a colored top/left stripe · over-rounded everything · **unmodified
  shadcn slate/zinc defaults** · bento-grid-for-its-own-sake · fade-up on every
  scroll section · tilt on every card · infinite logo marquee · confetti ·
  hype copy ("unlock / supercharge / seamless / world-class / trusted by
  thousands").

Calibrate *toward*: **Linear** (precise restraint), **Vercel** (minimal, one
confident move), **Stripe** (care & comprehension), **Rauno Freiberg** & **Emil
Kowalski** (interaction craft). Away from the effect-maximalist template.

## Non-negotiables

- **Reduced-motion / static-first is the design, not a checkbox.** Turn all
  motion off — the screen must still be excellent. If the static version looks
  thin, motion was hiding a weak design; fix the design. Wire
  `prefers-reduced-motion` from the start.
- **Design every reachable state** — not just the happy path. Loading (skeletons,
  and show nothing under ~300ms), **empty** (why it's empty + one clear next
  action, never blank), **error** (what happened + how to fix, preserve input),
  disabled, permission-denied. Respond within ~400ms (optimistic UI).
- **Ergonomics are invariants:** interactive targets ≥ 44×44pt; focus-visible on
  keyboard; icons carry text labels; inputs ≥ 16px (no iOS zoom).
- **Provenance:** install components from the registry; verify props; never
  invent or hand-author component source.

## This skill layers on good judgment — it doesn't replace it

Assume competent fundamentals (a grounded concept, real content, honest
hierarchy) and add *direction* on top. Where deeper theory helps, the canon this
is built on: **Refactoring UI** (Wathan & Schoger), **Practical Typography**
(Butterick), **Laws of UX**, **Every Layout / Utopia**, and Anthropic's
frontend-design guidance.

| skill **`uiforge:content`** | Step 5. Microcopy — outcome-labels, error/empty states, the hype blocklist, the specificity test. |
| `/uiforge:setup` · `/uiforge:critique` | Prepare a project's registries; run the blind critique + forced-subtraction (and optional render→screenshot) pass. |

**Do not** browse the parts for inspiration. The thesis and the direction — not
the catalog — decide what gets made. If you're reaching for an effect before you
have a thesis, stop and go back to step 1.
