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

plan-review 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 8d 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

Plan Review

저술 계획을 5축으로 비판하고 구체적 수정 제안을 돌려준다. 칭찬 금지, 근거 없는 비판도 금지.

5축 검토

질문 빨간불 신호
커버리지 주제 핵심 쟁점 중 빠진 게 있는가? 레퍼런스의 한 챕터 분량 내용이 한 단락으로 축소됨
내러티브 흐름 챕터 순서가 자연스러운가? 난이도 급등/급감, 맥락 없이 주제 점프
독자 적합도 대상 독자 수준에 맞는가? 입문자용인데 2장부터 고급 개념 가정
챕터 균형 분량·밀도가 고른가? 한 챕터가 다른 챕터의 3배 이상
중복·공백 같은 내용이 여러 장에? 인접 장의 주요 내용 70% 이상 겹침

절차

  1. 읽기02_plan.md + 01_reference.md를 순서대로
  2. 대조 — 레퍼런스의 각 섹션이 계획의 어느 장에 매핑되는지 표로 정리
  3. 5축 평가 — 각 축마다 문제 3개 이내로 압축 (과다 지적 금지)
  4. 우선순위 부여 — Critical / Should / Nice
  5. 구체적 제안 — 문제 진단뿐 아니라 어떻게 고칠지까지
  6. 전달SendMessagebook-planner에게

합의 유연성

  • 최대 2회 왕복까지 피드백
  • 저자가 설득력 있게 반박하면 물러설 것
  • 평행선 지속 → 최종 의견과 저자 결정을 모두 03_review_log.md에 기록, 팀 해체

금지 사항

  • "좋네요" 같은 공허한 긍정
  • 근거 없는 취향 비판 ("이 제목은 별로예요")
  • 저자가 의도적으로 선택한 전개를 모르고 통째로 바꾸자는 제안
  • 전체 재작성 요구 (심각한 경우에만, 근거 상세히)

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.
