Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is src: ./slides/01-title.md.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.

Fable 5.1 $0.00080 $0.05685
Opus 5 $0.00040 $0.02842

Security

Grade C, and why

slidev-master scanned grade C 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 7d 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Slidev Master Skill

개발자를 위한 마크다운 기반 프레젠테이션 프레임워크 Slidev의 완벽 가이드.

활성화 조건

다음 요청 시 이 스킬 사용:

  • Slidev 프레젠테이션 생성/수정
  • 기술 발표자료, 컨퍼런스 슬라이드
  • 코드 데모가 포함된 워크샵 자료
  • 마크다운 기반 슬라이드 제작

핵심 원칙 (Critical Rules)

1. 마크다운린트 설정 (필수)

슬라이드 작성 전 반드시 .markdownlint.json 생성:

{
  "MD003": false,
  "MD024": false,
  "MD025": false,
  "MD026": false,
  "MD033": false,
  "MD041": false
}
규칙 비활성화 이유
MD003 frontmatter 손상 방지 (setext→ATX 변환 차단)
MD024 슬라이드간 중복 제목 허용
MD025 각 슬라이드별 H1 허용
MD026 제목에 문장부호 허용
MD033 Slidev 인라인 HTML 허용
MD041 첫 줄이 YAML frontmatter

2. 접근성 기반 디자인 (Critical)

폰트 크기 (연구 기반):

  • 본문: 최소 18pt, 권장 18-24pt
  • 제목: 최소 24pt 이상
  • Sans-serif 글꼴 사용 (Arial, Helvetica, Inter)
  • 이탤릭, 밑줄, ALL CAPS 본문 사용 금지

색상 대비:

  • 일반 텍스트: 최소 4.5:1 대비율
  • 큰 텍스트 (>24pt): 최소 3:1 대비율
  • 색맹 친화적 팔레트 사용 (ColorBrewer 검증)
  • 색상만으로 정보 전달 금지 (패턴/라벨 병행)

기본 스타일 설정:

---
theme: default
---

<style>
h1 { font-size: 3rem; }      /* ~48pt */
h2 { font-size: 2rem; }      /* ~32pt */
h3 { font-size: 1.5rem; }    /* ~24pt */
p, li { font-size: 1.25rem; } /* ~20pt */

body {
  font-family: 'Inter', 'Helvetica Neue', Arial, sans-serif;
}
</style>

3. 콘텐츠 원칙

슬라이드당 하나의 아이디어:

  • 설명에 2분 이상 필요하면 분할
  • 제목은 명확한 주장 형태 ("성능" X → "API가 10K req/sec 처리" O)
  • 제목만 읽어도 스토리가 전달되어야 함

최소 텍스트:

  • 슬라이드당 50단어 미만
  • 완전한 문장 대신 키워드/구문
  • 상세 설명은 발표자 노트에

인지 부하 관리:

  • 슬라이드당 최대 6개 요소 (제목 + 다이어그램 + 불릿 등)
  • 6개 초과 시 v-click으로 점진적 공개

What ships with it

6 files 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.
