Not just "have AI summarize a book", but go further: turning a book or a document package into a Skill that an AI Agent can repeatedly call. This idea is worth discussing. Previously, after buying and reading a book, when I later wanted to find a certain knowledge point, I couldn't find it after flipping through for a long time; asking AI might make things up; throwing the entire PDF in would easily blow out the context with hundreds of pages, and token consumption would be high. Then I came across this tool: book-to-skill, which "digests" a book by breaking it apart. It can handle PDF, EPUB, DOCX, Markdown, and other files, and then converts the book into a Skill that Claude Code can call. After generation, there's a SKILL.md file containing the core framework and chapter index of the entire book; each chapter is split into a separate file, along with a glossary, pattern table, and quick reference table. The advantage is that it doesn't stuff the entire book into the context every time; instead, it only reads the part you ask about.
