book-to-skill Turns a Technical Book Into an Agent Skill and Claims 24x to 51x Fewer Tokens Than Dumping It Into Context
GitHub·medium signal
Leutenegger/book-to-skill (1,209 stars in 6 days, roughly 202 a day) distills a PDF, EPUB, DOCX, MD, HTML, RTF or MOBI file, folder or glob into a single skill usable from GitHub Copilot CLI, Amp or Claude Code, targeting the open Agent Skills standard rather than one vendor. The headline claim, measured on real books, is 24x to 51x fewer tokens to answer one question than putting the book in context. Install is 'pip install -e .' then 'book-to-skill install'.
