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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00104 | $0.02096 |
| Opus 5 | $0.00052 | $0.01048 |
| Sonnet 5 | $0.00021 | $0.00419 |
| Haiku 4.5 | $0.00010 | $0.00210 |
Grade A, and why
omd:codex-image 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 11d 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 — 165 lines — stays where its author put it; the contents beside it link to each section on GitHub.
omd:codex-image
채널-aware 이미지 materialization 스킬. 하나의 spec format + 세 가지 downstream 처리.
문제: oh-my-design이 emit하는 HTML/MD에는 늘 illustration 자리가 비어있다. 채널별 capability가 다르다 — Codex CLI는 내장 image generation을 갖고, Claude Code는 안 가졌고, OpenCode는 user에게 위임한다. 이 차이를 skill 1개로 통합한다.
0. 단일 spec format
artifact (HTML, Markdown, JSX, MDX) 안에 다음 주석 블록을 둔다.
<!-- omd:gen-image
filename: assets/karrot-hero.png
prompt: "Karrot mobile home feed screenshot — white canvas, warm near-black headings, single Karrot Orange #FF6600 floating CTA. Mobile portrait, no chrome."
aspect: "16:9"
style: "product screenshot, minimal, mobile"
references:
- https://www.daangn.com/
- https://seed-design.io/
notes: "Single saturated element per viewport. Use brand orange only on the CTA."
-->
<img src="assets/karrot-hero.png" alt="당근 홈 피드의 단일 오렌지 CTA" />
규칙:
filename— 결과물 저장 경로. 같은 디렉토리 기준 상대경로 권장.prompt— 한 문단, 구체적, 시각 디테일 + 톤 + 컬러 hex 포함.aspect—16:94:31:19:16중 하나.style— 1~3 단어 (product screenshot/inline svg/editorial photo/dieline diagram).references— 실제 브랜드 URL (선택, IP-safe 컨텍스트용).notes— generator나 검수자가 알아야 할 제약.
이 spec은 channel과 무관하다. 채널별 처리는 §1.
1. 채널 분기
호출 envelope의 channel (또는 환경 detect — process.env.OMD_CHANNEL이나 host agent 식별)에 따라:
1.1 channel = codex
Codex CLI는 native image generation을 갖고 있다. 다음 순서:
- artifact를 Read로 전체 로드
<!-- omd:gen-image ... -->블록을 정규식으로 추출 (multiline)- 각 블록마다 Codex의 image generation primitive 호출 — 도구명은 host에 따라 다르다 (
generate_image,image.create,dall_e_image_generation,gpt_image_1등). Codex agent가 자기 환경에서 사용 가능한 것을 선택한다. - 출력 파일을
filename경로에 저장 (mkdir -p) - 주석 블록은 그대로 두고
<img src>나![]()경로가 매칭되는지 확인. 안 맞으면 alt 텍스트 보존하면서 src만 교체. - 각 처리 항목에
<!-- omd:gen-image:done at=<ISO timestamp> by=codex -->주석을 spec 블록 아래에 1줄 추가.
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.

omd:codex-image is a skill published in the GitHub repository kwakseongjae/oh-my-design (498 stars, last pushed 4d ago), licensed MIT. It adds 104 tokens to every session and 2,096 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
