Turn Your Textbook Into a Claude Study Skill That Answers From the Real Chapter
book-to-skill is a free, open-source Claude skill that turns any book you own into chapter files, a glossary and a cheat sheet Claude reads on demand. How to install it, convert your first book, and study with it
book-to-skill is a free, open-source skill for Claude Code, past 36,000 GitHub stars. You point it at a textbook, and it turns the book into a structured skill: one file per chapter, a glossary, a patterns file and a cheat sheet. Then you ask Claude about a chapter, and it reads that chapter and answers from the real content.
Here's what it makes, how to set it up, and the limits you should know first.
What it makes from your book
- SKILL.md: the book's core ideas plus an index of every chapter.
- chapters/: one file per chapter, loaded only when you ask about it.
- glossary.md: every key term, sorted A to Z, with the chapter it comes from.
- patterns.md: every technique and method in the book.
- cheatsheet.md: decision tables and quick rules for revision.
