repo-to-book-skill

Turn any code repository into a beautiful, diagram-rich technical book (PDF, EPUB, and self-contained HTML). Use when the user wants to "make a book" / "write a book" / "architecture book" / "guide" / "deep-dive document" about a codebase, repo, or library — including cloning a GitHub repo first. Asks clarifying questions about style, audience, grounding, and formats, explores the code with parallel agents, writes the chapters, and builds the formats with rendered Mermaid + HTML/SVG graphics.
