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 →

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:asset-fetch 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.

omd:asset-fetch — Free-license Asset Catalog

왜 이 스킬

"초안 같음" 결과물의 90%는 placeholder가 너무 generic이라서 — [YOUR LOGO] 점선 박스, organic blob SVG, "image placeholder" 회색 사각형. 사용자가 "와우" 못 느낌.

이 스킬은 모든 placeholder 자리에 verified free-license CDN 자산을 박는 catalog. URL은 전부 200 OK 검증됨 (2026-05-14 기준).

핵심 원칙

  1. 검증된 URL만. 이 catalog에 없으면 generator가 임의로 만들지 말 것.
  2. 모든 자산은 commercial-use 허용 — 사용자 product에 ship 가능.
  3. 출처는 assets/attribution.md에 의무 기록 — URL + license + 사용 위치 + fetch 일자.
  4. deterministic seeding 권장seed 또는 lock 파라미터로 결과 재현 가능. 매번 다른 이미지 나오는 random URL은 피할 것.
  5. 금지: handcraft inline SVG로 placeholder를 "그려서" 채우기. catalog 자산 fetch 실패 시 → brand-color CSS gradient placeholder (이전 v1.3.4 fallback 정책과 동일).

Catalog (verified 2026-05-14)

1. LOGO — product name 워드마크만 (v1.3.7부터)

별도 icon / shapes mark / DiceBear logo 합성 금지. 헤더 logo = product name 텍스트 + 디스플레이 폰트, 그게 전부.

: AI가 합성한 icon mark는 "generic"하게 보임 (사용자 frustration source). product 이름을 꽤 괜찮은 폰트로 그대로 박는 게 진짜 brand wordmark처럼 보이고 사용자가 1초만에 자기 product name으로 swap 가능.

패턴:

<a class="logo" href="/" style="display:inline-flex;align-items:center;text-decoration:none;">
  <span class="logo-wordmark">{{PRODUCT_NAME}}</span>
</a>
<style>
  .logo-wordmark{
    font-family:"Bricolage Grotesque","Space Grotesk","DM Serif Display","Fraunces",-apple-system,sans-serif;
    font-size:22px;font-weight:700;letter-spacing:-0.04em;
    color:var(--color-text-heading);
  }
</style>

<head>에 디스플레이 폰트 <link> 의무 (§6 참고).

brand vibe별 폰트 매칭:

  • cool / minimal / fintech serious → Space Grotesk 700 (geometric)
  • warm / playful / community → Bricolage Grotesque 700 (friendly variable)
  • editorial / luxury → DM Serif Display 또는 Fraunces (display serif)
  • bold / display → Bricolage Grotesque 800

{{PRODUCT_NAME}} 결정:

  1. 사용자 prompt에 명시 product name 있으면 그대로 사용
  2. 없으면 brand vibe 맞는 generic placeholder 1개 선택 (omd-harness rule 5 §placeholder 표 참고: Folio, Mint, Pop, Spark, Townie, Lane, Compass, ...)
  3. 선택된 이름은 <title>, hero copy, footer brand 자리 전부 일관 적용 (사용자 grep replace 1번이면 swap 끝)

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.
