book-to-skill
Turns a technical book, a folder of documents or a collection of sources into a chunked skill: one main file holding the concepts, one file per chapter, a glossary and a cheat sheet. It reads PDF, EPUB, DOCX, HTML, MOBI, Markdown and half a dozen other formats, and the resulting skill follows the open Agent Skills standard, so it also works in Copilot CLI, Amp or Hermes, not only in Claude Code. When you ask a question, Claude loads only the files it needs. The book stays available from one session to the next without ever filling the whole context window. Two same-named repositories exist under `book2skills`, they are not this project.
Strengths
- The book loads in useful chunks rather than whole, which leaves the context window room to breathe
- The generated glossary and cheat sheet also serve outside the agent, for human reading
- The knowledge outlives the session: the book is reusable without being re-pasted every time
Limitations
- Chunking is automatic, so a book whose thesis builds chapter by chapter loses its thread
- The announced token gain comes from the creator and compares against the worst possible case, not normal usage
- Two same-named repositories circulate under a close name, you have to check which project you land on
Best for
- A reference work you reopen monthly: a standard, an API manual, a language guide
- Giving an agent a stable theoretical base that will not move between two projects
- Onboarding onto a domain whose vocabulary you lack: the generated glossary earns its place from session one
