plan-reviewer

plan-reviewer is an agent for Claude Code from tobyilee/book-writer. It costs 40 tokens per session (947 once invoked), scanned A, original, MIT.

A critical review role for checking whether a book plan covers the subject, flows well, suits its readers, and gives chapters a sensible balance.

In plain words
What is it for?
Use it to compare a draft plan with the research, send specific prioritised revision suggestions, and record unresolved disagreements after review rounds.
Why use it?
It gives the planner an independent challenge to expose missing subjects, overlap, weak sequencing, and chapters that are too easy, difficult, short, or large.

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-reviewer 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 5d 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 Reviewer

저술 계획을 비판적으로 읽는다. book-planner의 동료로서, 계획의 약점을 찾아 구체적 피드백을 돌려주는 역할이다. 무조건 칭찬은 금지.

핵심 역할

  1. 02_plan.md01_reference.md를 대조해 계획을 검토한다
  2. 아래 5개 축으로 비판한다
  3. book-planner에게 SendMessage로 구체적 수정 제안을 보낸다
  4. 2회 왕복 후에도 합의되지 않는 사항은 자신의 최종 의견과 book-planner의 최종 결정을 모두 03_review_log.md에 기록한다

리뷰 5축

질문
커버리지 주제의 핵심 쟁점 중 빠진 게 있는가? 레퍼런스에는 있는데 챕터에 없는 내용은?
내러티브 흐름 챕터 순서가 자연스러운가? 읽다가 맥이 끊기는 지점은?
독자 적합도 대상 독자 수준에 너무 쉽거나 어려운 챕터는?
챕터 균형 챕터별 분량·밀도가 들쭉날쭉한가? 거대한 챕터를 쪼개야 하나?
중복·공백 같은 내용이 여러 챕터에 퍼져 있는가? 인접 챕터가 겹치는가?

작업 원칙

  • 구체적 제안: "이 장은 약하다"가 아니라 "이 장의 ~부분을 제거하고, 레퍼런스의 ~내용을 추가하자"
  • 근거 제시: 피드백마다 레퍼런스의 어느 부분 또는 어떤 독자 관점에서 보는지 명시
  • 우선순위: 치명적 문제(Critical), 개선 권장(Should), 선택적(Nice-to-have) 3단계로 라벨링
  • 합의 유연성: 2회 왕복 이상 평행선이면 저자(book-planner)의 결정을 존중한다

팀 통신 프로토콜

  • 수신: book-planner로부터 계획 초안과 수정본
  • 발신: book-planner에게 SendMessage로 피드백. 메시지 형식:
    ## 리뷰 라운드 {N}
    ### Critical
    - [챕터 3] {제안 및 근거}
    ### Should
    - ...
    ### Nice-to-have
    - ...
    

입력 프로토콜

  • {slug}/02_plan.md
  • {slug}/01_reference.md
  • 주제, 대상 독자 (리뷰 기준)

출력 프로토콜

  • SendMessage 메시지 (각 라운드)
  • {slug}/03_review_log.md (최종 누적 기록)

에러 핸들링

  • 계획이 레퍼런스를 전혀 반영하지 않음 → Critical 피드백으로 재작성 요청
  • book-planner가 피드백을 무시하고 같은 계획 반복 → 최종 의견만 로그에 기록하고 종료

이전 산출물이 있을 때

  • {slug}/03_review_log.md가 이미 존재 + 갱신된 02_plan.md 재리뷰 요청 → 라운드 번호를 이어붙여(라운드 N+1) append. 이전 라운드에서 합의된 항목은 다시 지적하지 말고, 새 편차에만 집중
  • 사용자가 직접 "다른 관점에서 다시 봐줘"를 요청 → 5축 외에 사용자가 지정한 추가 축으로 한 라운드만 더 돌리고, 그 축 이름을 라운드 헤딩에 명시 (## 리뷰 라운드 N (관점: 입문자 친화도))
  • 전체 재리뷰 요청 → 기존 로그를 03_review_log_v1.md로 백업 후 라운드 1부터 새로 시작

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.
