oh-my-design: Skill for Claude Code

.claude/skills/omd-designer-review/SKILL.md

omd:designer-review is a skill for Claude Code from kwakseongjae/oh-my-design. It costs 87 tokens per session (2,698 once invoked), scanned A, original, MIT.

A review tool for checking an HTML, Markdown, or JSX interface against a brand’s DESIGN.md file, which records its visual rules. It reports findings without changing the files.

In plain words
What is it for?
Audit headings and text styles, brand-color usage, corner-radius values, component states, and responsive behavior, with BLOCK, WARN, or FYI findings and line references.
Why use it?
It helps catch inconsistent typography, colors, corner sizes, component states, and mobile layouts before release.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: names the AskUserQuestion tool; mentions Claude Code; mentions Codex.

This is kwakseongjae/oh-my-design's own configuration. It tells Claude Code how to work on oh-my-design itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything oh-my-design configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

omd:designer-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.

omd:designer-review

artifact를 받아 brand의 DESIGN.md 기준으로 visual / brand consistency를 audit한다. read-write가 아니라 advisory — 직접 수정하지 않고 review report만 emit.

구조는 mastepanoski/claude-skills ui-design-review에서 차용.

0. 필수 입력

  • artifact_path: HTML, MD, JSX, TSX 중 하나
  • design_md_path: 해당 브랜드의 references/<id>/DESIGN.md 또는 프로젝트 루트 DESIGN.md
  • (선택) viewport: mobile | desktop | both (default: both)

이 두 입력이 없으면 BLOCK으로 즉시 종료.

1. Audit 카테고리 (8)

1.1 Typography hierarchy

  • DESIGN.md § Typography 스펙 read
  • artifact 내 h1/h2/h3/p의 size, weight, line-height 추출
  • 일치 여부 검사
  • 빈 h-level skip (h1 → h3) → WARN
  • 본문 weight가 400/500이 아닌 700 fall-through → WARN

1.2 Color budget (Toss "2 saturated brand elements / viewport" rule)

DESIGN.md § Color의 brand saturated tokens 추출.

  • viewport당 brand saturated 사용 횟수 카운트
  • 2 → WARN (Toss principle 위반)

  • 4 → BLOCK

  • DESIGN.md에 없는 hex 직접 사용 → WARN
  • 회색 대신 saturated 사용 (예: warning이 아닌 컨테이너에 red-500) → WARN

1.3 Radius scale

  • DESIGN.md § Radius 토큰 read (예: 0, 4, 8, 12, 16, 9999)
  • artifact 내 border-radius 추출
  • 토큰에 없는 값 → WARN
  • 한 컴포넌트 안에서 radius 혼용 (8 + 12) → FYI

1.4 Component states

각 interactive 요소가 다음 state를 갖춰야:

  • default ✓
  • hover ✓
  • focus (focus-visible OK) ✓
  • active ✓
  • disabled ✓

누락 → BLOCK (focus는 a11y 필수)

1.5 Mobile responsiveness

  • viewport=both인 경우 mobile에서 검사
  • 최소 hit area 44x44 (iOS HIG) → BLOCK 미달
  • 가로 스크롤 발생 → BLOCK
  • 텍스트 14px 미만 → WARN

1.6 Spacing / layout

  • DESIGN.md § Spacing 토큰
  • 토큰 외 값 (예: padding: 13px) → WARN
  • 인접 요소 간 일관성 (한 카드 안에서 padding-x가 16 vs 20 혼재) → WARN

1.7 Text contrast (측정값으로만 — 눈대중 금지)

T3-3 레인 A에서 두 평가자가 합의한 결함 19건 중 11건이 CONTRAST였다. 브랜드 액센트 위 흰 글자, 사진·그라데이션 위 헤드라인, 회색 메타 텍스트가 반복 원인이다. 이 카테고리는 추정하지 않는다 — 숫자를 내고, 그 숫자를 이슈 본문에 적는다.

  • 렌더된 페이지가 있으면 omd check contrast <page.html>(레포에서는 node test-v2/tools/text-contrast.mjs)를 돌려 그 출력을 근거로 삼는다. 이 도구는 명목 색(computed color) 대 실제 배경 픽셀로 재고, 안티앨리어싱된 글리프 가장자리 픽셀로 평균을 내지 않는다.
  • 본문 텍스트 < 4.5:1 → BLOCK · 대형 텍스트(≥24px 또는 ≥19px bold)·필수 UI 경계·아이콘 < 3:1 → BLOCK
  • 포커스 링은 인접 배경 대비 < 3:1 → BLOCK (링 색은 최대 채도 지점으로 잰다 — halo를 링으로 착각하지 않는다)
  • 사진·영상·그라데이션 위 텍스트에 스크림/솔리드 받침이 없으면, 측정값이 통과해도 WARN (배경 이미지가 바뀌면 곧바로 깨진다).
  • 도구를 돌릴 수 없으면(렌더 없음·브라우저 없음) 그 사실을 WARN으로 적는다 — 통과로 적지 않는다.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
