oh-my-design: Skill for Claude Code

.claude/skills/omd-experiment-gallery/SKILL.md

omd:experiment-gallery is a skill for Claude Code from kwakseongjae/oh-my-design. It costs 107 tokens per session (2,188 once invoked), scanned A, original, MIT.

A single comparison page for several brand experiments, with each result shown in an embedded preview and linked as a standalone page.

In plain words
What is it for?
Use it after creating multiple brand experiments or when asking for a gallery. It can show names, ratings, refinement changes, previews, and available experiment metadata.
Why use it?
It makes results easier to review side by side than opening each experiment folder separately.

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:experiment-gallery 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 13d 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.

왜 이 스킬

여러 brand experiment를 돌리고 나면 결과물 검수가 산만 — 각 폴더 따로 열고 비교하기 번거로움. 이 skill은 단일 index.html 에 N개 결과를 iframe으로 박아서 한 화면에서 wow ratings + deltas + 실제 렌더를 동시 확인.

트리거

  • 명시: "결과물 한 번에 보여줘", "갤러리 만들어", "N개 비교 뷰"
  • 묵시: 사용자가 omd:harness로 ≥2개 brand experiment를 한 batch에서 끝낸 직후 ("이제 비교해보자" 라는 흐름)
  • 다른 skill 안에서 호출: omd:batch-launch가 5개 brand 끝낸 후 Phase 5로 호출

입력

다음 둘 중 하나:

  1. 명시 디렉토리 list: 사용자가 /tmp/omd-gallery/{brand1,brand2,brand3} 같은 list 제공
  2. 부모 디렉토리 + glob: /tmp/omd-gallery/* 또는 web/experiments/2026-05/* 등 — skill이 자동 enumerate

각 brand 디렉토리는 다음 파일들 있어야 함 (있으면 사용, 없으면 fallback):

  • landing.html (필수) — iframe src
  • DESIGN.md (선택) — brand display name 추출
  • assets/_reference/<id>/structure.json (선택) — composition 메타
  • assets/_reference/<id>/.live-inspect-proof.json (선택) — live tag 표시
  • screenshots/after.png (선택) — fallback preview
  • experiment-meta.json (선택, 권장) — wow rating + round-2 deltas + 카테고리 — sub-agent가 작성

experiment-meta.json 스키마 (sub-agent가 작성)

각 experiment sub-agent는 work 종료 직전 다음 파일을 작성:

{
  "brand_id": "toss",
  "brand_korean": "토스",
  "brand_category": "Fintech",
  "brand_color_hex": "#3182f6",
  "wow_rating": 7.5,
  "lines": 603,
  "live_inspect": { "ran": true, "raw_samples": 7, "method": "playwright|harness" },
  "round2_deltas": [
    "Reveal failsafe — 2s forwards animation",
    "Stat-card narrative upgrade",
    "CTA copy 구체화 (시간 약속)",
    "Hero shimmer (accent text gradient)",
    "Dark marquee band rhythm break",
    "Chart stroke-dashoffset draw-in"
  ],
  "ip_compliance": {
    "your_logo_placeholders": 2,
    "your_product_name_placeholders": 4,
    "brand_logo_embed_count": 0,
    "verbatim_brand_copy": 0

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.
