book-writer: Skill for Claude Code

.claude/skills/book-planning/SKILL.md

book-planning is a skill for Claude Code from tobyilee/book-writer. It costs 80 tokens per session (1,165 once invoked), scanned A, original, MIT.

A book-outline workflow that turns research into a title, book structure, chapter sequence, and description of what each chapter covers.

In plain words
What is it for?
Use it to plan technical books, practical guides, essays, or narrative works, including the reader's starting point, expected outcome, chapter questions, content, and approximate length.
Why use it?
It helps prevent missing topics, weak chapter order, uneven coverage, and a mismatch between the book and its intended readers.

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

book-planning 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 9d 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 Planning

리서치를 바탕으로 책 구조를 설계한다. 좋은 계획은 "독자가 어떤 여정을 거쳐 무엇을 얻는가"를 먼저 정하고, 거기서 역산해 챕터를 배치한다.

장르 프로필을 반영하자. 오케스트레이터가 확정한 genre(기본 tech-book)에 따라 챕터 단위·내러티브 아크·독자 여정의 해석이 달라진다. profiles/{genre}/scaffolds.md를 읽고 그 장르의 구조로 배치한다 — tech-book=개념/문제/사례 챕터, narrative=막·시퀀스·씬, practical=파트·단계·코스 묶음, essay=주제별 글 묶음.

절차

  1. 입력 소화genre, 01_reference.md, 활성 profiles/{genre}/scaffolds.md, 주제·대상 독자·분량 힌트를 읽는다
  2. 독자 여정 설계 (장르별로 출구 상태를 다르게 — "할 수 있다"/"느낀다"/"바뀐다")
    • 진입 상태: 독자가 이 책을 펼 때 어떤 지식·고민·기대를 가지고 있는가?
    • 출구 상태: 다 읽었을 때 무엇을 할 수 있고, 어떤 관점이 바뀌어 있는가?
  3. 제목 후보 3개 — 각각 다른 포지셔닝 (이론서 / 실전서 / 철학적 에세이 등) 톤
  4. 책 특성 정의 — 장르, 분량, 난이도
  5. 내러티브 아크 설계 — 챕터 흐름을 문단으로 서술 (왜 이 순서인지)
  6. 챕터 목록 작성 — 5~10개, 각 챕터에 핵심 질문 + 주요 내용 + 예상 분량
  7. 검증 — 아래 체크리스트로 자기 점검
  8. 저장{slug}/02_plan.md

독자 여정 템플릿

단계 질문
진입 이 독자는 왜 이 책을 집어들었을까?
각성 어떤 지점에서 "아, 내가 지금까지 놓친 게 있구나" 느끼게 될까?
배움 핵심 개념·기술을 어떻게 소화할까?
적용 어디서 실전 적용 기회를 느낄까?
종합 마지막에 무엇을 가지고 일상으로 돌아갈까?

챕터 배치 원칙

  • 첫 장은 왜(Why): 왜 이 주제가 중요한지, 왜 이 책인지
  • 중반은 무엇(What)·어떻게(How): 개념과 기법 교차 배치
  • 종반은 통합(Synthesis): 부분 지식을 통합 사고로 묶기
  • 마지막은 다음 걸음(Next): 독자가 덮고 나서 무엇을 할지

체크리스트

  • 모든 챕터가 핵심 질문에 답하고 있는가?
  • 챕터 순서에 맥이 흐르는가 (갑자기 난이도·주제 도약 없음)?
  • 대상 독자 수준에 맞는가?
  • 레퍼런스의 주요 자료가 빠짐없이 어딘가에 배치되는가?
  • 챕터 간 중복이 없는가?
  • 각 챕터 예상 분량 합계가 목표 분량에 부합하는가?

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.
