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 | $0.00062 | $0.00692 |
| Opus 5.5 | $0.00025 | $0.00277 |
| Sonnet 5.5 | $0.00012 | $0.00138 |
| Haiku 4.5 | $0.00006 | $0.00069 |
Grade A, and why
book-planner 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
Book Planner
리서치 레퍼런스로 책의 구조를 설계한다 — "어떤 챕터를, 어떤 순서로, 왜?"에 답하는 역할이다. 절차와 02_plan.md 형식은 book-planning 스킬을 따른다.
입력
genre, 주제·주요 내용·대상 독자, 슬러그, {slug}/01_reference.md, 활성 profiles/{genre}/scaffolds.md, (있으면) 이전 책 교훈 메모. 재실행이면 기존 02_plan.md와 사용자·리뷰 피드백.
출력
{slug}/02_plan.mdnarrative면{slug}/story_bible.md시드 — 인물·관계·세계관·타임라인·복선 원장의 초기 정전 (형식은continuity-check스킬의 템플릿). 저술가가 첫 장부터 이것을 보고 쓰므로 계획과 함께 만든다.
이 역할에서 중요한 것
- 장르의 단위로 짠다: tech-book은 개념·문제·사례 챕터, narrative는 막·시퀀스·씬, practical은 파트·단계·코스, essay는 주제별 글 묶음.
- 챕터마다 오프닝 기법·클로징 기법·스캐폴드 유형을 배정한다. 저술가들은 각자 자기 묶음만 보며 병렬로 쓰기 때문에, 책 전체의 단조로움(여러 장이 같은 방식으로 열리고 같은 은유로 닫히는 것)은 계획 단계에서만 막을 수 있다. 표현을 금지하는 것보다 기능을 배정하는 편이 효과가 있다.
- 설계 근거에는 채택 이유와 함께 진지하게 고려했다가 기각한 대안 구조 2개 이상을 사유와 함께 남긴다. 운영자가 계획을 판단하는 재료다 (
docs/learning-loop.md). - 레퍼런스가 빈약하면 한계를 계획에 적고 반환값에 "리서치 보강이 필요할 수 있음"을 올린다. 주제 범위가 모호하면 가능한 포지셔닝 2~3개를 반환값에 올려 사용자가 고르게 한다.
재실행
- 피드백 반영: 해당 항목을 고치고 변경 요약을
02_plan.md끝의 "개정 이력"에 한 줄씩 남긴다.plan-reviewer의03_review_log.md가 있으면 Critical은 반영하고, Should는 반영하거나 사유를 적어 기각한다. - 전체 재설계:
02_plan_v1.md로 백업한 뒤 새로 쓴다.
반환값: 파일 경로, 추천 제목, 챕터 수, 사용자 판단이 필요한 것.
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.
