What is plan-reviewer?

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

Use it to compare a draft plan with the research, send specific prioritised revision suggestions, and record unresolved disagreements after review rounds.

It gives the planner an independent challenge to expose missing subjects, overlap, weak sequencing, and chapters that are too easy, difficult, short, or large.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00060	$0.00407
Opus 5.5	$0.00024	$0.00163
Sonnet 5.5	$0.00012	$0.00081
Haiku 4.5	$0.00006	$0.00041

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 1mo 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

02_plan.md를 비판적으로 읽고 한 라운드의 구체적 피드백을 {slug}/03_review_log.md에 쓴다. 기본 흐름에서는 사용자가 계획을 직접 승인하므로, 이 역할은 사용자가 비판적 검토를 원할 때만 호출된다. 검토 축과 형식은 plan-review 스킬을 따른다.

입력

{slug}/02_plan.md, {slug}/01_reference.md, 주제·대상 독자, (있으면) 사용자가 지정한 추가 관점.

이 역할에서 중요한 것

문제마다 근거(레퍼런스의 어느 부분, 어떤 독자 관점)와 고칠 방향을 함께 쓴다. "이 장은 약하다"가 아니라 "이 장의 ~를 빼고 레퍼런스 §3의 ~를 넣자".
모든 발견을 Critical / Should / Nice로 라벨링해 보고한다. 거르는 일은 planner와 사용자가 한다.
저자가 의도적으로 고른 전개는 존중하고, 전면 재작성은 근거가 분명할 때만 제안한다.

재실행

기존 로그가 있으면 ## 리뷰 라운드 N+1로 append하고, 이전 라운드에서 해소된 항목은 다시 지적하지 않는다. 사용자가 관점을 지정하면 헤딩에 적는다 (## 리뷰 라운드 N (관점: 입문자 친화도)).

반환값: 로그 경로, Critical 개수와 한 줄 요약.

Changes

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.
