Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00099 | $0.02491 |
| Opus 5 | $0.00049 | $0.01246 |
| Sonnet 5 | $0.00020 | $0.00498 |
| Haiku 4.5 | $0.00010 | $0.00249 |
Grade D, and why
install-skills scanned grade D with 2 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 9d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

이 저장소의 skill을 선택하여 설치합니다.
클린 설치(기존 설치본 삭제 후 복사)와 개발 전용 경로(tests/ 등) 배포 제외의 단일 출처는 설치 절차 5단계입니다.
규칙 배경(결정적 헬퍼의 테스트는 스킬 디렉토리에 함께 두되 배포에서 제외)은 이 repo의 ADR 0001에 있습니다. repo 전용 문서라 설치본에서는 열람할 수 없어 링크하지 않습니다.

추가 옵션
| 옵션 | 설명 |
|---|---|
--clear |
설치 전 대상 skills 디렉토리 내부를 비웁니다 — 동작은 설치 절차 2단계. |
--self |
install-skills 자신을 설치 대상에 포함합니다 — 절차는 아래 Self-install 부트스트랩. |
--clear는 스킬명 변경 등으로 기존 스킬이 남아 있을 때 유용합니다. 디렉토리 자체(~/.claude/skills/등)는 유지됩니다.
Self-install 부트스트랩
install-skills는 홈에 한 벌만 두고, 어느 스킬 repo에서든 복제본 없이 실행하는 것을 전제로 합니다.
- 이 저장소 루트에서 최초 1회
/install-skills --self를 실행해install-skills자신을 홈(예:~/.claude/skills/install-skills/)에 설치합니다. - 이후에는 다른 스킬 repo 루트를 cwd(current working directory, 현재 작업 디렉토리)로
/install-skills를 실행하면, 그 repo에 복제본이 없어도 홈 설치본이 그 repo의 skill을 스캔·설치합니다.
self-install에도 일반 설치와 동일한 절차(클린 설치, 배포 제외 패턴)가 적용됩니다.
사용 가능한 skill
설치 대상 목록은 본문에 고정하지 않고, 실행 시점에 저장소를 스캔하여 동적으로 구성합니다.
스킬 repo 판별 가드 — 스캔 전에 cwd가 스킬 repo인지 먼저 확인합니다. */SKILL.md가 1건 이상 매칭되면 통과, 하나도 매칭되지 않으면 스킬 repo가 아닌 것으로 판정하고 경고 후 안전하게 중단합니다. 단일 스킬 repo도 지원 대상이므로 1건 통과는 설계 의도이며, 다만 1건만 매칭되면 해당 디렉토리가 스킬 repo가 맞는지 사용자에게 확인한 뒤 진행합니다 (이 확인은 아래 스니펫이 아니라 지침을 실행하는 AI가 대화로 수행하며, 스니펫은 0건 차단만 담당합니다). 임의의 cwd에서 실수로 실행해 엉뚱한 디렉토리를 소스로 삼는 오설치를 막기 위한 가드입니다.
# 스킬 repo 판별 가드 — */SKILL.md 가 0개면 중단 (셸 내장만 사용 — bash nullglob·zsh 모두 안전)

if [ "$found" != "true" ]; then
echo "스킬 repo가 아닙니다 (*/SKILL.md 없음) — 설치를 중단합니다." >&2

What ships with it
4 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.
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.

install-skills is a skill published in the GitHub repository scroogy-dev/scroogy-agent-skills (2 stars, last pushed 3d ago), licensed Apache-2.0. It adds 99 tokens to every session and 2,491 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it D with 2 findings (reads agent configuration directories, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
