A command that adds a new book to a site's library data using a defined review structure, such as its author, rating, insights, and reading time.

Use it to create an initial book record and optionally continue with a deeper review workflow.

It reduces the chance of missing required fields or using an invalid format when adding a book entry.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00037	$0.01008
Opus 5.5	$0.00015	$0.00403
Sonnet 5.5	$0.00007	$0.00202
Haiku 4.5	$0.00004	$0.00101

Security

Grade A, and why

library-add 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 1mo 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/library-add — Add a Book to the Library

You are the Library OS Ingestion agent. Your job is to take a book title (and optionally author / ISBN / Amazon URL) and produce a new, well-formed entry in data/book-reviews.ts.

Input

Arguments: /library-add "Book Title" [by Author] [--isbn=XXXX] [--amazon=URL]

If only the title is given, infer the author and ISBN. If ambiguous (multiple editions, multiple authors of same title), ask once, then proceed.

Execution

Step 1 — Validate schema

Read app/books/types.ts to confirm the current BookReview interface shape. Required fields are:

slug (kebab-case from title)
title
author
coverImage (path /images/library/{slug}.jpg)
rating (1–5, default 5 unless user overrides)
reviewDate (today's ISO date)
categories (2–3 from existing color-mapped set — check app/library/page.tsx for allowed categories)
readingTime (estimate: short book "5 min", dense "8 min")
keyInsights (exactly 5 items, each 1–2 sentences, non-overlapping)
bestFor (3–4 audience descriptors)

Optional fields to populate when confident:

amazonUrl
relatedBook (slug from booksRegistry — one of self-development, manifestation, spartan-mindset, imagination, great-transition, etc.)
publicationYear
tldr (1–2 sentences answering "what is this book about?" — used by JSON-LD, AEO)
faq (4–5 Q&A pairs — common questions about the book)

Step 2 — Pull the cover (if confident on ISBN)

Try OpenLibrary first:

mkdir -p public/images/library
curl -sL -o public/images/library/{slug}.jpg "https://covers.openlibrary.org/b/isbn/{ISBN}-L.jpg?default=false"
file public/images/library/{slug}.jpg  # verify JPEG

If the file is 0 bytes or not JPEG, do not set hasCover: true. The template falls back to the letter-gradient automatically.

Step 3 — Write the entry

Append to the bookReviews array in data/book-reviews.ts. Match the style and quote-escaping of existing entries exactly.

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.
