book-creation is a skill for Claude Code, Codex from equinor/neqsim. It costs 18 tokens per session (6,822 once invoked), scanned A, a copy of book_creation, Apache-2.0.

A workflow guide for creating scientific books in PaperLab, a project system for writing and rendering books. It covers chapters, references, notebooks, and output formats such as HTML, Word, PDF, and ODF.

In plain words
What is it for?
Use it to start book projects, organise chapters and front matter, run book notebooks, build the project, and troubleshoot rendered outputs.
Why use it?
It provides a defined project layout and build process for book-length scientific work. It also distinguishes book creation from workflows intended for individual papers.

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-creation scanned grade A with 1 finding 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 27d 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.

Skill: Book Creation in PaperLab

When to Use

USE WHEN: creating a new scientific book project, writing chapter content, running book notebooks, building/rendering a book, or troubleshooting the book pipeline. This skill covers the complete lifecycle from book-new to final rendered outputs in HTML/Word/PDF/ODF.

DO NOT USE for: paper writing workflows (use write-methods-section, journal-formatting, etc. instead).


1. Book Project Structure

Every book lives under neqsim-paperlab/books/<slug>_<year>/. The critical file is book.yaml — it defines metadata, chapter ordering, parts, and rendering settings.

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.
