Library OS

The open-source Library Intelligence System. Captures everything you read into a permanent, intelligent, citation-ready knowledge library on your own website.

When to use this skill

• User mentions adding a book, book review, reading list, library
• User shares handwritten notes, book highlights, Kindle exports, or a photo of notes
• User says "I just finished [book]" or "let me capture this book"
• User asks about the book system, /library/*, or wants to port it to another site
• User wants to deepen a shallow review into a hub page

Core philosophy

1. Own your library. Kindle highlights die in Kindle. Notion docs scatter. A library on your own site, in git, becomes a permanent asset that compounds for decades.
2. Data schema is the spine. The template is interchangeable; the BookReview type + its sub-types are the interoperable core. Port to any Next.js, Astro, SvelteKit, or even static HTML.
3. Structured, not scraped. Every book is curated — quotes carry chapter references, chapter summaries carry key ideas, related reading carries a reason, not a category tag.
4. AEO-first. Every book page emits BreadcrumbList + Article + Review + FAQPage + Quotation schema. Citation surface is the product.
5. Repeatable, not bespoke. One data schema, one template, one command pipeline. Every new book follows the same path. No snowflakes.
