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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00017 | $0.06811 |
| Opus 5 | $0.00009 | $0.03406 |
| Sonnet 5 | $0.00003 | $0.01362 |
| Haiku 4.5 | $0.00002 | $0.00681 |
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 5d 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.

Expected in a hook, worth knowing in a rule or an instructions file.

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.

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.

book_creation is a skill published in the GitHub repository equinor/neqsim (150 stars, last pushed today), licensed Apache-2.0. It adds 17 tokens to every session and 6,811 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
