oh-my-design: Skill for Claude Code

.claude/skills/claude-design/SKILL.md

claude-design is a skill for Claude Code from kwakseongjae/oh-my-design. It costs 290 tokens per session (8,901 once invoked), scanned A, original, MIT.

A skill that examines a code project and prepares its design details—such as the technology, visual rules, screens, text and brand assets—for Claude Design, a browser-based design tool. It then sends that context there to create a design and returns the result link.

In plain words
What is it for?
Use it when you want to turn a codebase or folder into a design brief for Claude Design, create a landing-page design, or share the project’s repository, important files and visual assets.
Why use it?
It removes the need to manually explain an existing project before asking for design work. If browser interaction is blocked, it switches to a manual handoff.

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

claude-design 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 12d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/analyze_codebase.py, scripts/clickable_link.sh, scripts/collect_source.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Claude Design 컨텍스트 이관 스킬 (v2)

현재 코드베이스를 분석해 디자인 컨텍스트 브리프를 합성하고, 그것을 claude.ai/design 에 전달해 디자인을 생성한 뒤, 결과 링크를 터미널에 클릭 가능한 OSC-8 하이퍼링크로 돌려준다. 이 문서는 설명서가 아니라 런타임 Claude가 그대로 따르는 실행 플레이북이다.

v2의 핵심: ① 코드베이스 → 디자인 컨텍스트 이관(스택/토큰/컴포넌트/라우트/실제 카피/에셋/ 레포 링크), ② 컨텍스트 깊이를 매 실행 선택(lean ↔ comprehensive), ③ 렌더 스크린샷 캡처 안 함(기존 이미지 에셋 업로드는 가능), ④ 풀오토 + 핸드오프 폴백(claude.ai/design 상호작용이 막히면 알려진 확장 충돌 버그로 보고 즉시 수동 전환).

스크립트 경로 규칙: 런타임 cwd 는 보통 사용자의 프로젝트 폴더다(스킬 폴더가 아님). STEP -1에서 현재 채널·scope의 스킬 위치를 CLAUDE_DESIGN_SKILL_DIR 절대경로로 한 번 해석한 뒤 모든 스크립트를 그 변수 아래에서 호출한다. --root 스캔 대상은 cwd ($PWD), 즉 분석할 프로젝트 폴더다.

무엇을 하는가

  • 코드베이스를 분석해 디자인 컨텍스트 브리프(스택, 디자인 토큰, 컴포넌트, 라우트, 실제 UI 카피, 큐레이션된 브랜드 에셋, git 레포 URL + 핵심 파일 경로)를 합성한다.
  • 코드가 있으면 레포를 링크하고(브리프에 git URL + 핵심 파일 경로), 실제 브랜드 비주얼 에셋(로고/심볼/OG/히어로 등 — 문서 템플릿이 아님)을 큐레이션해 업로드한다.
  • 대화 맥락 + 브리프 + 에셋 + URL 레퍼런스를 묶어 claude.ai/design 에 holistic 하게 전달하고, 결과 캔버스 URL 을 받아 터미널에 클릭 링크로 출력한다.

언제 쓰나 / 언제 안 쓰나

  • 쓴다: "이 코드베이스를 클로드 디자인으로 옮겨줘", "코드 분석해서 claude design에 보내줘", "랜딩 디자인 뽑아줘" 처럼 코드/폴더 컨텍스트를 Claude Design 으로 넘길 때.
  • 안 쓴다: 텍스트 디자인 조언/카피만 원할 때(브라우저 불필요), 코드로 UI 를 직접 구현할 때(일반 코딩 작업), 로그인/CAPTCHA 자동 돌파가 필요할 때(사용자에게 위임).

워크플로 (STEP -1 → 7)

각 단계의 MCP 도구는 ToolSearch 로 먼저 로드한 뒤 호출한다(select:<tool_name>). 셀렉터/라벨은 확정이 아니라 검증할 힌트다. 같은 단계에서 2~3회 실패하면 멈추고 핸드오프하거나 사용자에게 묻는다(루프/삽질 금지).

STEP -1 — SKILL_DIR resolve (채널·project/global 공통)

하드코딩된 ~/.claude/skills를 쓰지 않는다. 아래를 한 번 실행하고 SKILL_DIR_OK를 확인한다:

PROJECT_ROOT=$(git rev-parse --show-toplevel 2>/dev/null || pwd)
CLAUDE_DESIGN_SKILL_DIR=""
for candidate in \
  "$PROJECT_ROOT/.claude/skills/claude-design" \
  "$PROJECT_ROOT/.agents/skills/claude-design" \

  "$(npm root -g 2>/dev/null)/oh-my-design-cli/skills/claude-design"
do
  if [ -f "$candidate/SKILL.md" ] && [ -d "$candidate/scripts" ]; then
    CLAUDE_DESIGN_SKILL_DIR="$candidate"
    break
  fi
done
[ -n "$CLAUDE_DESIGN_SKILL_DIR" ] && echo "SKILL_DIR_OK=$CLAUDE_DESIGN_SKILL_DIR" || echo "SKILL_DIR_MISSING"

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.
