oh-my-design: Skill for Claude Code

.claude/skills/omd-init/SKILL.md

omd:init is a skill for Claude Code from kwakseongjae/oh-my-design. It costs 118 tokens per session (6,499 once invoked), scanned A, original, MIT.

A setup process for creating a project's `DESIGN.md`, a guide that tells coding agents how the project should look and feel. It recommends a real design reference and installs compatibility files for several coding-agent tools.

In plain words
What is it for?
Use it when a project has no `DESIGN.md` or needs a design system set up. It helps choose a reference, adapt its visual style to the project, and prepare the design guide for agent use.
Why use it?
It gives a project a shared visual direction before interface work begins, reducing inconsistent design decisions across tasks.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; mentions CLAUDE.md; names the AskUserQuestion tool.

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 →

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Prompt Injection · line 5
    Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.
    Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
  • medium Agent Snooping · line 397
    Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
    Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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:init scanned grade A with 1 finding 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/query-references.mjs), 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

omd:init — DESIGN.md Bootstrap

프로젝트에 DESIGN.md + AI 코딩 에이전트용 shim 3종을 한 번에 세팅. 레퍼런스 톤&매너는 preserve하고, 사용자 프로젝트 맥락은 controlled-vocabulary delta_set으로만 반영.

레퍼런스 선택과 graph draft는 host agent 안에서 처리하지만, Core projection과 authority hash는 직접 만들지 않는다. 설치된 provider-free omd design-md 도구가 inspect/migrate/compile을 담당한다. omd init recommend, omd init prepare, omd sync 같은 별도 runtime subcommand는 제공하지 않는다.

전체 플로우

Phase 1: 사용자 맥락 파악 (1-2 질문)
Phase 2: 레퍼런스 추천 (fingerprint 기반 in-head 점수)
Phase 3: 사용자가 1개 선택
Phase 3.5: 적용 형태 확인 (루트 부트스트랩 / 참고용 저장 / 기존 파일 교체 여부)
Phase 4: 레퍼런스 DESIGN.md Read + delta_set 추출
Phase 4.5: 프로젝트 권위 입력 수집
Phase 5: Core v2 System Graph draft → canonical compiler → staged adopted package
Phase 6: Shim 3종 설치 (omd:sync skill 위임)
Phase 7: 요약 출력

Phase 1 — 맥락 파악

이미 충분한 description이 있으면 skip. 부족하면 최대 2개 질문:

  1. 프로젝트 유형/도메인 (SaaS / 랜딩 / 대시보드 / 이커머스 / 커뮤니티 등)
  2. 분위기 키워드 (warm, minimal, premium, playful, dense, airy 등)

한 번에 하나씩, 또는 통합해서 한 번에. 질문 쌓지 말 것.

Phase 2 — 레퍼런스 추천 (file-based, no CLI)

2.1 카탈로그 로드

다음 파일을 Read 툴로 전체 로드 (있는 순서대로 fallback):

  1. .codex/data/reference-fingerprints.json (Codex 설치 카탈로그)
  2. .claude/data/reference-fingerprints.json (Claude Code / Cursor 설치 카탈로그)
  3. .opencode/data/reference-fingerprints.json (OpenCode 설치 카탈로그)
  4. node_modules/oh-my-design-cli/data/reference-fingerprints.json (npm 설치 직접 경로)
  5. data/reference-fingerprints.json (개발 환경)

스키마: { count, items: [{ id, primary_color_hex, category, visual_theme, voice_fingerprint, tone_keywords, antipatterns, signature_motion, has_personas, category_raw }] }.

추가 보조 파일 (있으면 같이 로드):

  • 위에서 실제 선택된 data dir의 vocabulary.json — controlled vocab axes/keywords
  • 같은 data dir의 reference-tags.md — human-readable keyword matrix

필수 품질 파일:

  • 같은 data dir의 reference-quality.jsonverified_v2 | partial | legacy_snapshot

fingerprint는 있는데 품질 파일이 없거나 두 파일의 count/id 집합이 다르면 다른 채널 파일로 섞어 보완하지 않는다. omd install-skills를 다시 실행하고 omd doctor로 확인하라고 안내한 뒤 reference 추천을 중단한다.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
