Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00215 | $0.02753 |
| Opus 5 | $0.00108 | $0.01376 |
| Sonnet 5 | $0.00043 | $0.00551 |
| Haiku 4.5 | $0.00021 | $0.00275 |
Grade A, and why
ebook-publishing 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 11d 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.
This is a copy
100% identical to ebook-publishing — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 270 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ultimate Ebook Publishing Skill

Project Context
If project-context.md exists in the skill directory or .claude/ folder, read it
before any task. It contains brand voice, publishing setup, platform credentials
paths, and infrastructure details — avoids re-explaining context each session.
Workflow Overview
1. Write & Structure
2. Format (EPUB / PDF / HTML→PDF)
3. Cover Design
4. ISBN Decision
5. Platform Strategy (wide vs exclusive, ebook + print + audio)
6. Metadata & SEO
7. Pricing & Royalties
8. Pre-launch + Launch + Post-launch
EPUBCheck Compliance (EPUB 3.0)
EPUBs must pass EPUBCheck for D2D, Apple Books, Kobo, and most aggregators. Common errors and fixes:
| Error | Fix |
|---|---|
<script> tags |
Remove all — EPUB content docs don't allow JavaScript |
<button> tags |
Remove all |
<input>, <select>, <textarea>, <form> |
Remove all form elements |
Event handlers (onclick, onmouseover, etc.) |
Remove all on* attributes |
Orphan <dt>/<dd> outside <dl> |
Convert to styled <p> tags (see below) |
| CSS unbalanced braces | Remove @media blocks (limited EPUB reader support), validate brace count |
Broken fragment identifiers (href="#id" where id missing) |
Convert <a> to <span>, remove href |
| OPF-014 "scripted" property | Caused by script tags — removing scripts fixes it |

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.
