Written for Claude Code and Codex: user-invocable in frontmatter, but also runs codex exec. Also seen: positional $N argument; mentions Codex.

This is kwakseongjae/oh-my-design's own configuration. It tells Claude Code and Codex 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:media 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 8d 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.

omd:media — 브랜드 자산 세트, 가진 채널로

입력은 DESIGN.md(토큰·서사·금지)와 .omd/config.json(omd:setup이 저장한 채널·예산)이다. config가 없으면 먼저 omd:setup을 돌린다 — 채널을 추측하거나 "키를 발급받으라"고 말하지 않는다.

1. 프롬프트 팩 (채널 무관, 항상 만든다)

assets/generated/<set>/PROMPTS.md — 항목마다:

  • 역할(히어로 / 섹션 n / 아이콘 / OG) · 비율 · 크기
    • 비율은 기본값에서 고르지 말고 「그 이미지가 들어갈 자리」에서 가져온다. 레이아웃 슬롯의 실제 종횡비를 재고(렌더가 있으면 그 박스, 없으면 설계 폭÷높이), 브랜드 증거가 있으면 그 브랜드 이미지의 관행 비율과 맞춘다. 히어로 16:9·OG 1.91:1·아이콘 1:1은 자리를 못 잰 경우의 최후 기본값이지 출발점이 아니다.
    • 근거: T3-3 레인 A 108칸에서 **생성 이미지의 비율이 브랜드 이미지 관행에서 10% 넘게 벗어난 칸이 60%**였고, 근거 추종 축의 기계 수치는 세 도구 모두 40 이하였다(omd 33.8 · hallmark 34.6 · uiuxpromax 35.9). 페이지 안에서 잘려 나가는 비율은 p90 0.37로 오히려 완만했다 — 문제는 배치가 아니라 생성 시점에 고른 비율이다.
  • 프롬프트 원문: 컨셉 한 문장 + 피사체 + 구도 + 빛·질감 + 팔레트 hex 잠금(DESIGN.md 토큰 인용 경로) + 금지(얼굴·로고·텍스트·스톡 느낌)
  • 스타일 참조: assets/_reference/ 캡처가 있으면 경로(Recraft style_id 생성 입력)
  • 랜딩이면 storyboard.md의 섹션별 에셋 계획을 그대로 읽는다(중복 작성 금지).

2. 채널 실행 (config media.image 순서대로, 실패 시 다음)

2.0 세트는 배치로 — openai-batch (OPENAI_API_KEY 가 있을 때 기본)

12~40장 세트는 낱장 호출이 아니라 OpenAI Batch API 로 한 번에 넣는다(출력 토큰 50% 할인, 공식 확인). 도구: node test-v2/tools/image-batch.mjs run --spec <set.json> --out <dir>plan 은 오프라인이라 키 없이도 JSONL 과 비용 구조를 미리 볼 수 있다. 스펙의 styleSuffix모든 프롬프트 끝에 토씨 그대로 붙는다 (우리 채널에는 시드가 없어 세트 일관성은 이것과 참조 이미지뿐이다). 참조 이미지가 있는 슬롯은 /v1/images/edits 배치로 자동 분리된다(최대 16장). 결과는 images/<id>.png + results.json(sha256·usage) + ledger.json(비용). size 는 슬롯 실측 비율에서 고른다 — 허용 목록·제약은 도구가 검증한다.

채널 호출 산출
grok-build grok --prompt-file <p> -m grok-4.6 --always-approve --cwd <run> — 프롬프트는 "image_gen으로 생성해 <path>로 cp" 지시 jpg/png
codex-imagegen codex exec "<prompt>… save to <path>" ($imagegen, ChatGPT 로그인) png
gemini-nanobanana gemini -p + nanobanana 확장(/generate) png
xai-api POST /v1/images/generations (grok-imagine-image-2.0) — env XAI_API_KEY jpg
recraft-api style 생성(참조 1–10장 → style_id, 레퍼런스별 1회) → svg 생성 svg
없음 프롬프트 팩 + assets/generated/QUEUE.md(사람이 돌릴 목록) + 팔레트 추상 SVG 플레이스홀더

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.
