24×–51× fewer tokens than dumping the book into context to answer one question, measured on real books (how it's measured).
How it works, in 3 steps:
- Point it at a file, folder, or glob —
/book-to-skill ./my-book.pdf - It distills the book into a skill — frameworks, decision rules, anti-patterns, and per-chapter files. Structure, not a summary.
- Your agent loads it on demand — ask
/my-book replicationand it reads the right chapter and answers from the real content, no hallucination.
🤔 Why

You buy a great technical book. You read it once. Three months later you can't remember chapter 7 existed.
The usual workarounds don't help:
- 📄 "Let me just search the PDF" → you get a list of pages, not answers
- 🧠 "I'll ask the agent about this book" → it either hallucinates or says it doesn't have the content
- 📝 "I'll take notes as I read" → you end up with a 200-line doc you never open again
book-to-skill solves this by turning the book into a structured skill your agent loads on demand.
Once installed, you just type /your-book-slug replication and the agent reads the right chapter and answers from the actual content. No hallucination. No digging through PDFs.
