What it does

Book Genesis is an agent skill from felipelobomotta-blip/book-genesis-studio. Use when someone wants to write a complete book from an idea, even a one-line one, or to continue, audit, revise or package a book in progress. Book Genesis plans the book, drafts every chapter in a consistent voice, has blind simulated readers and a read-only auditor critique it, revises in bounded passes, and delivers a commercial-length manuscript with a scored report and an editorial package (logline, blurb, synopsis, query letter, cover brief). The author agrees at each step or lets it run to the end…

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 39 other files, including reference files (for example `agents/openai.yaml`, `references/hosts.md` and `references/patterns/ai-tells-en.md`).

It sits in Writing & Content, covering Creative writing and fiction. The repository describes itself as: Open-source writing skills for Claude Code, Codex, OpenCode, Antigravity, Gemini, OpenClaw, and Hermes. Your creativity. Your agent. Your book. The licence is MIT.

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Read references/pipeline/host-contract.md. It covers starting, resuming, checking in with the author, and recovering from failures.
  2. Read references/prompts/orchestrator.md. It is the main loop.
  3. Open or create the author's book folder. If PROJECT_STATE.yaml exists, resume from it; otherwise start at Phase 0 with whatever idea the…

What it can do on your machine

Read from SKILL.md and the folder at commit 46a744f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Book Genesis loads about 1.2k tokens when it runs, and up to ~68k if it reads all its reference files. Until then it costs about 148 tokens; SKILL.md has 471 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~148
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~68k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use when someone wants to write a complete book from an idea, even a one-line one, or to continue, audit, revise or package a book in progress. Book Genesis plans the book, drafts every chapter in a consistent voice, has blind simulated readers and a read-only auditor critique it, revises in bounded passes, and delivers a commercial-length manuscript with a scored report and an editorial package (logline, blurb, synopsis, query letter, cover brief). The author agrees at each step or lets it run to the end. Fiction and memoir first; nonfiction works but is not calibrated.

Book Genesis

Take an idea to a complete, commercial-length book inside the author's own agent: planned, drafted, read blind, audited, revised and packaged, with every decision saved to files.

The goal is a book written with the measured patterns of books readers finish, audited the way a demanding editor would audit it, and packaged to sell. It is a goal, not a promise: no workflow can guarantee sales.

Start here

  1. Read references/pipeline/host-contract.md. It covers starting, resuming, checking in with the author, and recovering from failures.
  2. Read references/prompts/orchestrator.md. It is the main loop.
  3. Open or create the author's book folder. If PROJECT_STATE.yaml exists, resume from it; otherwise start at Phase 0 with whatever idea the author gave.

Resolve every references/... path from this skill's folder. The author's files live in the book folder:

text
<book>/
  PROJECT_STATE.yaml   ASSUMPTIONS.md   RUN_REPORT.md
  artifacts/           plan, audit, score and package files (00 to 13)
  manuscript/chapters/ chapter-01.md, chapter-02.md, ...
  evaluations/         panel verdicts, continuity checks, revision passes
  delivery/            proofread manuscript and exports
  work/                chapter briefs, draft attempts, critic packets

The eight phases

Load only the active phase's prompt and the references references/pipeline/manifest.yaml lists for it.

PhasePrompt
Phase 0: Intakereferences/prompts/intake.md
Phase 1: Foundationreferences/prompts/foundation.md
Phase 2: Architecturereferences/prompts/architecture.md
Phase 3: Draftingreferences/prompts/drafting.md
Phase 4: Adversarial Auditreferences/prompts/adversarial-audit.md
Phase 5: Revision Loopreferences/prompts/revision-loop.md
Phase 6: Final Scorereferences/scoring/genesis-score.md
Phase 7: Editorial Packagereferences/prompts/editorial-package.md

references/pipeline/phases.md is the one-screen overview.

What makes the criticism worth reading

  • Critics are blind. Readers see only prose; the auditor sees the plan but never targets or earlier scores; the writer never sees the rubric. references/scoring/evaluator-protocol.md sets who sees what.
  • Independence is measured and shown. Critics run in isolated subagents or in a second installed tool from another model family when the host allows it (references/hosts.md). Every verdict carries its grade.
  • Four readers decide, not one. Primary, hostile, adjacent-genre and casual readers, built per book (references/roles/panel.md, references/roles/blind-reader.md).
  • Two gates, bounded. The panel decides whether the book holds readers; the rubric (references/scoring/genesis-score.md) decides what to fix. Three passes per gate, then an honest stop.
  • Measured patterns, named sources. references/patterns/index.md points to prose, structure and emotion patterns from named books and studies, and to machine-prose tells in English and Brazilian Portuguese.

Specialists

Load when the phase calls for them:

  • references/specialists/research.md: comps and market in the book's own language
  • references/specialists/narrative-foundation.md: characters, theme, voice and the rhythm contract
  • references/specialists/prose-craft.md: openings, chapter endings, dialogue, revision moves
  • references/specialists/continuity.md: the ledger and the five-chapter checks
  • references/specialists/revision-editor.md: ticket-driven, targeted revision
  • references/specialists/production.md: proofreading and export
  • references/specialists/series.md: only when the book belongs to a series

Rules that never bend

  • Save important decisions to files; keep PROJECT_STATE.yaml true to what exists.
  • Never skip Phase 4, and never score before it.
  • Write the book and every message to the author in the book's language.
  • A book is "complete" when it meets its length contract (or a declared short form), every planned chapter exists, and the package exists. Quality gates are reported beside that label, never hidden.
  • Never claim a book will sell, is a bestseller, or is ready to publish without a human decision.
