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

double-diamond 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 10d 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.

Double Diamond Skill

문제를 발산적으로 탐색하고 수렴하는 4단계 디자인 방법론입니다.

다이아몬드 1: 올바른 문제 찾기

Discover 단계 (발산)

문제 공간을 넓게 탐색합니다:

  • 현장 조사: 실제 사용자 관찰
  • 인터뷰: 이해관계자 심층 인터뷰
  • 데이터 분석: 기존 로그와 메트릭 분석
  • 경쟁 분석: 유사 솔루션 조사
목표: 가능한 한 많은 인사이트 수집
방법: 가정하지 말고 관찰하라

Define 단계 (수렴)

수집한 인사이트에서 핵심 문제를 정의합니다:

  • 어피니티 다이어그램: 패턴 그룹화
  • How Might We: 문제를 기회로 재정의
  • Problem Statement: 한 문장으로 문제 정의
Problem Statement 형식:
[사용자]는 [맥락]에서 [목표]를 달성하려 하지만 [장애물] 때문에 어렵다.

다이아몬드 2: 올바른 해결책 개발

Develop 단계 (발산)

다양한 해결책을 탐색합니다:

  • Crazy 8s: 빠른 아이디어 스케치
  • 프로토타입: 저충실도 프로토타입
  • 사용자 테스트: 빠른 검증
  • 반복: 학습 기반 개선

Deliver 단계 (수렴)

최종 해결책을 선택하고 구현합니다:

  • 평가 기준 설정: 무엇으로 성공을 측정할 것인가?
  • 최종 선택: 최적 솔루션 결정
  • 구현 계획: 단계별 실행 계획
  • 측정 방법: KPI 설정

적용 체크리스트

  • Discover: 최소 5가지 인사이트 수집
  • Define: 명확한 Problem Statement 작성
  • Develop: 최소 3가지 해결책 탐색
  • Deliver: 검증 가능한 성공 지표 정의

전환 판단 기준

단계 → 다음 단계 조건
Discover → Define 충분한 인사이트 수집 완료
Define → Develop 핵심 문제 합의 완료
Develop → Deliver 솔루션 검증 완료

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.
