Skills

A skill is a written instruction manual that Claude follows for one job, like "turn this chapter into a narration script". Each one is a folder with a SKILL.md file (the instructions) and sometimes a small program for the mechanical parts. Together, 12 skills cover the whole path from idea to audiobook.

How a skill works

  1. You ask"Check chapter 2 for speech flow."
  2. Claude picks the skillEvery skill has a short description of when to use it. Claude matches your request to it.
  3. It follows the stepsClaude does the parts that need judgement and runs scripts for the mechanical parts.
  4. It stops and hands backYou see the result and decide. Nothing goes further without your OK.

Writing

Stage 0ours

story-seed

A brainstorming partner for the very start. It turns a one-line idea into a set of choices (twists, heroes, endings) and helps the author choose.

A one-line premise→seed.md, with the author's choices, open ideas, rejected ideas and parked ideas kept apart

ClaudeAuthor

Stage 1–5ours

fantasy-novella

The project manager and the main writer. It knows the order of the work, keeps each book's files tidy, and writes the chapters.

An idea, then the story bible and outline→Chapter files (ch01.md …) plus notes on facts, names and progress

ClaudeAuthor

Stage 2vendored

story-structure

Maps where the big turning points of the story should fall, so the middle doesn't sag and the ending lands.

The story bible→outline.md, with every chapter and the turning point it carries

ClaudeAuthor

Stage 1, 4, 5vendored

fiction-workshop

A team of editors in a box. It interviews the author to build the story bible, edits like a professional, and tests the book on a reader who has never seen it.

The author's answers, then the full manuscript→story-bible.md, edit notes, and a fresh-reader report

ClaudeAuthor

Stage 1, 4vendored

character-archetypes

Checks that every important character has a clear, distinct job in the story, such as mentor, rival or gatekeeper.

The character list in the story bible→Notes on each character's role and how to sharpen it

ClaudeAuthor

Stage 4vendored

prose-mechanics

A sentence-level proofreader for style. It finds repeated words, weak verbs, monotonous sentence lengths and other habits that wear on a reader.

Finished chapters→A list of findings, each with where it is and how serious it is

ClaudeAuthor

Stage 3, 4vendored

avoid-ai-writing

Finds and removes the tell-tale habits of AI-generated text, so the prose sounds like a person wrote it.

A chapter→A list of AI-sounding phrases, or a cleaned-up chapter

Claude

Voice

Stage 6ours

speech-flow

Fixes the text so it sounds right when read aloud. A listener can't see commas, italics or where a sentence is heading.

A finished chapter→A table of suggested fixes; once approved, the corrected chapter

ScriptClaudeAuthor

Stage 7ours

narration-prep

Turns each chapter into a script the voice engine can read correctly, with names spelled out phonetically and pauses written in.

A finished chapter, plus the pronunciation list→A script file (audio/ch01.txt …)

ClaudeScript

Stage 8ours

kokoro-narrate

The narrator. It reads the scripts aloud with a free AI voice that runs on this laptop, with no cloud service.

Script files→One audio file per chapter (audio/ch01.wav …)

ScriptAuthor

Stage 9ours

listen-check

A robot proof-listener. It transcribes the finished audio and compares it with the script, so problems come back as a short list of timestamps instead of 90 minutes of listening.

The chapter audio and its script→A list of moments to listen to (chapter, time, what was expected, what was heard)

ScriptClaudeAuthor

Package

Stage 10ours

audiobook-assemble

The sound engineer and packager. It evens out the volume, then builds one audiobook file with chapters, a cover and the title.
