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

1-prd 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

req-organizer — 요구사항 정리

requirements/ 폴더의 원본 문서를 읽고 구조화된 PRD.md를 생성합니다. "요구사항 정리", "v1 요구사항 정리해줘" 요청 시 사용합니다.

Instructions

다음 단계를 순서대로 수행하세요.

1. 버전 확인

  • 사용자가 버전을 지정한 경우 해당 버전 사용 (예: v1, v2)
  • 미지정 시 현재 진행 중인 버전 사용 (가장 최신 버전 디렉토리 확인)

2. 원본 문서 읽기

  • .specs/v{N}/requirements/ 하위의 모든 원본 문서를 읽기
  • PRD.md는 읽기 대상에서 제외

3. 중복/상충 식별 및 병합

  • 문서 간 중복되는 내용 식별
  • 상충되는 요구사항이 있으면 명시
  • 관련 내용을 논리적으로 병합

4. PRD.md 생성/갱신

다음 구조로 .specs/v{N}/PRD.md를 생성합니다:

# v{N} 요구사항 정리

## 출처

- (참고한 원본 문서 목록)

## 페이지 목록 (도출)

| 페이지 | 설명 | 우선순위 |
| ------ | ---- | -------- |
| ...    | ...  | ...      |

## 주요 요구사항

### {페이지명}

- 기능 요구사항 항목들

## 제약 조건 / 참고 사항

- 기술적/비즈니스 제약

## 미확인 사항

- [ ] 추가 확인이 필요한 항목들

5. 기존 PRD.md 처리

  • 기존 PRD.md가 이미 존재하는 경우, 새로운 원본 문서 내용을 반영하여 갱신
  • 기존 내용을 완전히 대체하지 않고, 변경된 부분만 업데이트

6. 품질 기준 적용

  • 요구사항을 단순 나열하지 않고, 각 기능이 포브스 TOP 10 기업에 납품해도 부족함이 없는 수준인지 평가
  • 단순 CRUD에 머무는 요구사항이 있으면 실무에서 바로 활용 가능한 수준으로 끌어올릴 확장 가능성을 미확인 사항에 제안
  • 성능(빠른 응답)과 UX 완성도(토스급) 관점에서 추가로 고려할 사항이 있으면 제약 조건 / 참고 사항에 명시

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.
