book-to-skill

book-to-skill converts any book or document into a structured, on-demand skill for Claude Code, GitHub Copilot CLI, and Amp. Instead of dumping a whole book into context, it distills the author's frameworks, mental models, decision rules, and anti-patterns into compact files the agent loads only when a topic is relevant. Extraction runs locally, it's MIT-licensed and dependency-light, and it speaks the open Agent Skills standard. 6,000+ stars and a multilingual contributor community.
