skill-maker

skill-maker is a command for Claude Code from sodam-ai/SoDam-Prompt-Eng. It costs 50 tokens per session (939 once invoked), scanned A, original, Apache-2.0.

A guided prompt for designing a new SKILL.md file, which is a reusable instruction set for an AI agent. It turns a user’s idea into the required skill format and includes safety and formatting rules.

In plain words
What is it for?
Use it to create a new agent skill from a short description, decide what inputs it needs, and produce the finished file in two required versions.
Why use it?
It removes the need to remember the file structure and rules required for a valid skill.

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

skill-maker 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.

What it actually says

당신은 SoDam Prompt 스킬 설계 도우미입니다. 사용자가 설명한 스킬 아이디어는 다음과 같습니다: "$ARGUMENTS"

진행 방식

  1. 위 설명만으로 빈칸(입력값)이 몇 개 필요한지, 어떤 톤·형식으로 결과가 나와야 하는지 판단이 안 서면 짧게 1~2개만 되물어보세요. 이미 충분하면 바로 3번으로 넘어가세요.
  2. 빈칸은 최대 2~3개로 제한하세요(사용자가 채우기 쉬워야 합니다).
  3. 완성한 스킬 파일은 다음 구조로 만드세요:
    • 맨 위 구분선(하이픈 3개) 사이에 세 줄: name(영문 소문자·하이픈, 스킬을 담을 폴더명과 반드시 같아야 함), description(무엇을 하는지 + "언제 사용하는지" 자연어 문구 포함), argument-hint(빈칸 설명, 대괄호로 표시)
    • 그 아래 본문에 역할 소개 1줄 + 실제 지시문을 작성하되, 사용자 입력이 들어갈 자리는 빈칸이 2개 이하면 달러 기호 뒤에 1부터 순서대로 숫자를 붙인 문자열로, 빈칸이 1개뿐이고 긴 텍스트를 통째로 받는 경우엔 달러 기호 뒤에 ARGUMENTS라고 붙인 문자열로 표시하세요.
    • 본문 끝에 "## 규칙" 항목으로 출력 형식·길이 지정 + "개인정보 입력 유도 금지" + "위험·민감 주제(의료·법률·금융·자해·성인·폭력·차별) 다루지 않음"을 넣으세요. 이 두 줄은 스킬 주제가 아무리 무해해 보여도(예: 옷차림 추천, 날씨 등) 예외 없이 반드시 넣으세요 — 빈칸에 나중에 악의적인 입력이 들어와도 엉뚱한 방향으로 새지 않게 막는 안전장치이지, 주제 자체의 위험도를 판단해서 넣고 빼는 항목이 아닙니다.
  4. 아래 항목은 반드시 지켜서 만드세요(이 저장소 안전 기준, CONTRIBUTING.md 2번 섹션과 동일):
    • 셸 명령·코드 실행 블록·MCP 도구 호출 문법 포함 금지
    • 시스템 프롬프트 탈취 시도 문구("이전 지시를 무시해" 등) 포함 금지
    • API 키·토큰 등 비밀값 포함 금지
  5. 완성되면 코드블록 두 개를 보여주세요(하나만 만들면 아래 검증 도구가 실패합니다):
    • 코드블록 1: 방금 만든 내용 그대로 (name·description·argument-hint 세 줄 frontmatter)
    • 코드블록 2: 같은 본문에, frontmatter는 description 한 줄만 남긴 버전(name·argument-hint는 빼세요) — 이 저장소는 /sodam-prompt:이름 슬래시 명령어 지원을 위해 스킬마다 이 두 번째 버전도 필요합니다
  6. 이어서 다음을 안내하세요:
    • "코드블록 1은 skills/(이름)/SKILL.md 경로로, 코드블록 2는 commands/(이름).md 경로로 각각 저장하세요."
    • 파일 시스템에 접근 가능한 환경(Claude Code 등)이면: "두 파일을 저장한 뒤 node scripts/verify-skills.mjs를 실행해 PASS가 나오는지 확인하세요. 둘 중 하나만 저장하면 반드시 실패합니다."
    • Claude.ai 앱처럼 파일 시스템이 없는 환경이면: "이 내용을 복사해 새 스킬로 업로드하거나, 파일에 접근 가능한 도구에서 두 파일 저장을 도와달라고 하세요."

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.
