qrcoding-logo-librarian

qrcoding-logo-librarian is a skill for Claude Code from contentscoin/qrcoding-skill-mcp. It costs 79 tokens per session (961 once invoked), scanned A, original, MIT.

A workflow for adding official organization or brand logos to generated images through deterministic compositing rather than asking an image model to draw them. It finds official Korean institution logo sources and supports user-provided logo links.

In plain words
What is it for?
Use it to place a verified logo on a poster, artwork, or QR image, manage a list of logo sources, or specify the logo's position, size, and composition style.
Why use it?
It reduces distorted or inaccurate logos in generated artwork and keeps logo placement, size, and source under explicit control. It also records reusable logo assets when the service's paid features are available.

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

qrcoding-logo-librarian 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 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.

What it actually says

QR Coding Logo Librarian

생성되는 이미지(포스터/아트워크)에 기관·브랜드 로고를 정확히 삽입한다. 핵심 원칙은 QR과 동일하다: 로고를 이미지 모델이 그리게 하지 말고, 검증된 소스(로고 URL)에서 가져와 결정적으로 합성한다. 유료 플랜 전용 기능이다.

로고 소스

  1. 기관 로고 — getlogo.kr
    • getlogo.kr은 한국 관공서·공공기관 로고 디렉터리다. 파일을 직접 호스팅하지 않고 공식 출처 링크만 중계한다.
    • 기관명/분류(중앙·지자체·공공기관)/지역으로 검색 → 해당 기관 항목 → **공식 출처(기관 공식 사이트의 CI/BI 페이지)**로 이동해 공식 로고 파일 URL을 확보한다. 가능하면 PNG 또는 SVG.
    • 상표·저작권은 각 권리자에게 있다. 허가된 용도로만 사용하고, 로고를 변형·재색·왜곡하지 않는다.
  2. 본인 로고 — 링크 첨부
    • 사용자가 제공한 로고 이미지 URL(https 또는 data:image)을 그대로 사용한다.

로고 리스트 관리

  • 수집한 로고를 {이름, url} 형태의 리스트로 관리한다(예: "행정안전부 → https://…/logo.png").
  • 재사용이 필요하면 로고를 워크스페이스 라이브러리에 영속화한다: 이미지를 받아 base64 data:image/... 로 만들어 upload_logo 호출 → logoAssetId 확보. (단 upload_logo는 PNG/JPG/WebP ≤100KB만 허용, SVG 불가. SVG 로고는 배치 시 URL을 직접 쓰면 된다.)
  • 라이브러리 조회/삭제는 list_logos / delete_logo.

정확한 배치 (핵심)

먼저 사용자에게 위치·크기·사용 방법을 물어 프롬프트에 반영한 뒤, compose_qr_overlaylogo를 함께 전달한다:

compose_qr_overlay(
  id,
  imageTool: "gpt-image" | "gemini" | "codex",
  placement: "card" | "transparent" | "framed",
  logo: { url, position, size, note }
)
  • position: top-left · top-right · bottom-left · bottom-right · top-center · bottom-center · center (기본 top-right)
  • size: small(~12%) · medium(~18%) · large(~26%) — 이미지 너비 대비 (기본 small)
  • note: 사용 지침(예: "가로형 로고 사용", "주위 여백 확보", "헤더에 배치")
  • 반환되는 지시문은 "그 위치에 로고 자리를 비우고, 모델이 그리지 말고, 생성 후 URL의 실제 로고를 결정적으로 합성(QR과 그 여백 침범 금지, 색·비율 변형 금지)"을 담는다.

유료 게이팅

  • 로고 배치는 유료 플랜 전용이다. 무료 플랜이 logo를 넣으면 로고 가이드 없이 업그레이드 안내만 반환된다.
  • 시작 전 get_account_status로 플랜을 확인하고, 무료면 업그레이드를 안내한다.

검증

  • QR과 로고를 모두 합성한 뒤 validate_qr_scanability로 스캔 가능성을 확인한다.
  • 지원 옵션이 헷갈리면 get_capabilitiesimageOverlay(placement·logoPlacement)를 먼저 확인한다.
