labnnine/book-to-skill ? reverse-engineered prompt

Build me a tool that turns a technical book, or even a folder of docs, into a reusable agent skill that I can load in Claude Code, Copilot CLI, or Amp.

I want to point it at a PDF, EPUB, DOCX, HTML, markdown, or a whole folder, and have it extract the important ideas, chapter by chapter, then generate a clean skill with a main instructions file, per chapter notes, a glossary, patterns, and a quick reference sheet. It should keep the generated skill organized so the agent can load only the parts it needs when I ask about a topic, instead of dumping the whole book into context.

Please make it easy to use from the command line, include a clear install and usage flow, and add docs so someone can convert a book, update an existing skill, and publish it if they want. If anything in the docs is unclear, look up the current agent skill format online and follow that.
