What it contains

Skills (18)

book-academic — Academic writing craft reference: IMRAD and discipline structures, literature review, argument chains, citation integrity, academic register in en/ko/ja, and academic-writing AI tells. Read by all agents on theses, dissertations, monographs
book-draft — Phase 3: Drafting. Voice lock on a sample chapter, then sequential full-context chapter drafting with draft-critique-revise, bible ledger updates, and periodic continuity checks.
book-edit — Phase 4: Editing. Fact-check (nonfiction), assessment, developmental edit, line edit, copy edit, proofread, then a cold read by simulated readers that issues the readiness verdict. Rewrites the manuscript; does not only file reports.
book-fiction — Fiction craft reference for all subgenres: structure options, scene design, character depth, dialogue, POV and distance, the fiction-specific AI tells, and language notes. Read by architect, scene-generator, chapter-writer, editors, and bet
book-game — Game narrative craft reference: branching architecture, quest design, dialogue systems, lore bible, player agency, and game-writing AI tells. Read by all agents on game scenarios, visual novels, and interactive fiction.
book-genre-creator — Meta-skill for genre selection and custom genre creation. Routes a project to the right built-in genre or composes a genre-custom.md spec from existing patterns, including agent behavior and validation rules.
book-ideation — Phase 1: Ideation. Stress-test the premise, research real comparable titles, generate and rank concepts, offer voice samples, and lock a single concept with a reader promise.
book-illustrate — Alias for /book-visuals limited to diffusion illustrations (scene, header, spot art). Kept for compatibility; new work should use /book-visuals, which also covers diagrams, charts, technical drawings, photos, and the art bible.
book-init — Phase 0: Onboarding. Define genre, reader, language, scope, and voice; capture the author's voice fingerprint; index source material; generate PRD.md and STYLE.md.
book-nonfiction — Nonfiction craft reference: argument architecture, evidence discipline, narrative in nonfiction, chapter design, the nonfiction-specific AI tells. Read by all agents on nonfiction, memoir, business, self-help, essay, and narrative nonfictio
book-outline — Phase 2: Outlining. Build the chapter-by-chapter outline with genre structure, create the book bible, validate structure with book-architect, and get author approval.
book-poetry — Poetry craft reference: forms, the line, image, sound, compression, collection architecture, and poetry-specific AI tells. Read by all agents on poetry collections, chapbooks, and poetry-essay hybrids.
book-publish — Phase 5: Publishing. Gate on readiness, assemble front and back matter, build EPUB/PDF/MOBI/TXT/Markdown with Pandoc, validate with epubcheck, produce metadata, title candidates, cover concepts, and marketing plan. Includes KDP and Korean p
book-screenplay — Screenplay craft reference: format, three-act and sequence structure, scene construction, dialogue subtext, A/B/C story weaving, series bibles, and screenplay-specific AI tells. Read by all agents on film, TV, and web-series projects.
book-status — Book project status and progress dashboard. Scans the project, writes status.json for the web UI, and reports phase, chapters, readiness score, and metrics.
book-technical — Technical book craft reference: concept gradient, running project, failure-first teaching, code standards, diagrams, exercises, version handling, the technical-book AI tells. Read by all agents on programming, engineering, and data science
book-visuals — Book visual system: art bible and look lock, figure plan per chapter, code-rendered diagrams/charts/technical drawings, diffusion-generated illustrations and spot art, photo sourcing policy, cover, model-agnostic prompt compilation, vision
loom — Velith router. Detects book project state and runs the next phase of the 6-phase pipeline (onboarding → ideation → outlining → drafting → editing → publishing) to the human-quality bar. Trigger: /loom, /velith, or any book-writing request.

Subagents (12)
