What does this agent skill do?
Design Score
/ss-review tells you what's wrong. /ss-score tells you how good it is
overall and what to fix first — a single number plus a category breakdown, so
you can track UI quality like you track test coverage.
When NOT to use
- For a quick pass/fail before committing → use
/ss-lint - For a full prose audit with fixes → use
/ss-review - For non-UI files (logic, config) — scoring is meaningless
What to score
Score the file (or each file in a directory) on six weighted categories that map to the design language. Total = 100.
| Category | Weight | Reads from |
|---|---|---|
| Color discipline | 16 | DESIGN-LANGUAGE §1, §18, §72 + VISUAL-CRAFT §C4 |
| Hierarchy & typography | 16 | §2, §3, §4, §16 + Font Size table + VISUAL-CRAFT §C2 |
| Layout & rhythm | 12 | §13, §14, §15, §61 + VISUAL-CRAFT §C1 |
| Cards & elevation | 10 | §7, §8, §12, §1 + VISUAL-CRAFT §C3 |
| States & a11y | 18 | §11, §70, §71, §72 + VISUAL-CRAFT §C3 |
| Motion & interaction | 6 | §24, §59 + engine/motion |
| Coherence | 12 | VISUAL-CRAFT §C0 (one choice per axis) |
| Distinctiveness | 10 | Golden Rules 14–16 + VISUAL-CRAFT §CC-9b (not generic/default/template) |
How to score each category
For each category, start at full marks and subtract for violations you find by reading the code. Be specific and evidence-based — cite the line.
Color discipline (16) — deduct for: any #000/text-black (−4 each, cap −8);
more than one accent hue used decoratively (−5); emoji used as UI icons (multi-color,
breaks single accent) (−5); a normal/OK/"보통" state shown in a status color instead of
neutral grey (−4); status color on most/every row (no severity hierarchy) (−4);
decorative hues (gold stars, rainbow category dots) instead of accent/grey (−3);
hardcoded hex where a semantic token exists (−2 each, cap −6); status conveyed by color
alone (−4); the unlocked default indigo (#5E6AD2/#4F46E5) used as the accent instead of
a chosen domain-fit color (−4).
Distinctiveness (10) — a coherent screen can still read "AI-generated." Deduct for: the icon-chip cliché — a generic Lucide line-icon in an identical pale-tinted rounded-square, repeated for every feature/step (−4, §CC-9b); the StyleSeed demo layout copied verbatim (hero+chat / 3-step / feature-grid / pricing) with no product-specific identity (−4); no focal point — an all-even grid of same-weight, centered, evenly-spaced cards (−3); the hero shows a stock/placeholder visual instead of this product (−3); the escape hatch as a new uniform (§CC-9c) — ghost 01/02/03 index numbers on every section, or identical uppercase-overline + big-number cards repeated with no variation (−2); distinctive-but-dated (§CC-9d) — full beige/paper page base, serif body text on a product surface, dark-heavy blocks that read "brochure" not "2026 product" (−3). Cap −10.
Hierarchy & typography (16) — deduct for: number/unit not ~2:1 (−4); font
sizes off the Font Size table / text-[var(--…)] for size (−5); everything the
same weight, no clear primary (−5); cramped or wrong line-height on body (−3);
body < 16px on a desktop/web B2B surface (tight mobile scale on a wide screen) (−4 —
but dense-data chrome is exempt: chart ticks, mono SHAs/timestamps, table metadata at
12–13px are correct; and dashboard app-chrome h1 at 22–24px is correct, not a violation
of the marketing 40–56px headline scale).
Layout & rhythm (12) — deduct for: content on bare background, not in cards
(−6); px-4/px-8/mx-4 instead of px-6/mx-6 (−3); same section type
repeated in a row (−4); no space-y-6 rhythm (−3).
Cards & elevation (10) — deduct for: 1px borders doing separation work that tone+shadow should (−4, LIGHT mode only — in DARK mode hairline borders + a tonal surface ramp ARE the correct elevation language, don't deduct); shadows over ~8% opacity / visibly heavy, or drop shadows used in dark mode (−4); no card/background tone separation (−5).
States & a11y (18) — deduct for: missing empty/loading/error state on a data
surface (−5 each, cap −10 — a static mockup or marketing landing with NO data surface is
N/A: skip these deductions, don't fail the category); contrast below 4.5:1 body / 3:1
large (−6); touch target < 44px on a touch surface (pointer-first desktop controls at
36–40px are fine) (−4); no visible focus / outline:none (−5); icon-only control
without aria-label (−3).
Motion & interaction (6) — deduct for: random/ad-hoc fades instead of a named
seed/keyword (−3); motion that delays content or blocks an action (−4); no
prefers-reduced-motion handling on custom motion (−3). Scroll-linked/parallax/3D/animated-
gradient is SURFACE-DEPENDENT (§43): on an app/dashboard/data/form surface it's forbidden
(−5); on a marketing/landing/brand page it's ALLOWED (the Cinematic tier) — there, do NOT
deduct for scroll-linked reveals, pinned sections, 3D hero, or animated backgrounds; only deduct
for scroll-JACKING (hijacking scroll / trapping) (−5), motion that hides content until scroll
or delays the headline/CTA (−4), or a missing prefers-reduced-motion fallback (−3). Judge by
page type first, then score.
Coherence (12) — the "one choice per axis" laws (VISUAL-CRAFT §C0). Deduct for
each axis that is mixed rather than unified across the file: mixed radius
personalities, e.g. sharp panel + pill buttons (−5); two+ competing accent hues used
for emphasis (−4); mixed shadow languages / light directions (−3); mixed icon
families, fill modes, or stroke weights (−3); same radius on a nested element instead
of inner = outer − padding (−2); inconsistent control heights for buttons/inputs
(−2). This is the category that most predicts "looks AI-generated" — weight evidence
of system-wide consistency, not per-component prettiness.
Clamp each category at 0. Sum to a total.
Output format

Color discipline 13/18 ▓▓▓░ #000 headings (l.12,40); orange+blue+green accents (l.28-34)

### Fix first (highest score gain)
1. Add empty + loading states to the orders list → +7 states (§71)
2. Unify radius (pick soft 8-12px) + collapse to one accent → +9 coherence+color (§C0, §2)
3. Drop the 1px borders, use tone + ≤8% shadow → +4 cards (§7)
Re-score after: ~92 / 100.
Use letter bands: 90+ A · 80-89 B · 70-79 C · 60-69 D · <60 F.
Gate mode (use this as the Quality Gate before showing the user UI)
The Quality Gate (CLAUDE.md / AGENTS.md) is /ss-score run as a loop, not a one-off:
- Score the just-generated UI.
- If < 80, apply the "fix first" list (use
/ss-reviewto make the edits), then re-score. - Repeat up to ~3×, or until ≥ 80.
- Present the UI with the final score and a one-line "fixed: …".
The pass bar is a floor, not a ceiling — get to ≥ 80 and stop; don't chase 100. The point is that no first-draft, obviously-incoherent UI reaches the user. Especially never ship below 80 with a rainbow status list, emoji icons, two accents, or missing states — those are the exact tells the gate exists to catch.
Rules
- Read the file — score from real evidence (line numbers), never guess.
- Order the "fix first" list by score gain, not by severity alone — the goal is the fastest path to a better number.
- For a directory, print a one-line score per file, then the lowest-scoring file's full breakdown.
- Don't auto-edit in plain scoring.
/ss-scoremeasures;/ss-reviewand/ss-motionfix. In Gate mode (above) you do fix-and-re-score until the floor is met. - As a gate, ≥ 80 is a floor before showing the user — but don't over-polish: chasing 95→100 to delay shipping is worse than shipping a clean 85.
