What problem does it solve? Writing long-form technical documentation that reads like a real printed textbook requires complex typesetting—tables of contents, page numbers, indexes, running heads, and figure numbering—that is painful to build and maintain by hand. This Skill turns a simple HTML fragment into a fully typeset Japanese technical reference PDF with all of those elements generated automatically. ## Core Features & Use Cases - Automatic book apparatus: Cover page, chapter openers, auto-generated table of contents with page numbers, running heads, page cross-references, figure/table numbering, and a fifty-sound-ordered index are all produced without manual numbering. - Textbook components: POINT callouts, warnings, sidenotes, term definitions, worked examples, end-of-chapter exercises with answers, columns, and syntax-highlighted code blocks via Pygments. - Page size presets and SVG diagrams: A4/B5/A5 presets with margin-tuned layouts, plus inline SVG patterns for architecture, sequence, layer, flow, and attack-flow diagrams. - Use Case: Draft chapter content as HTML fragments, run the build script with a title and B5 preset, and receive a print-ready technical reference PDF with clickable bookmarks, TOC, and index. ## Quick Start Ask the AI to write your technical material as chapter HTML fragments and build a B5 textbook PDF with a title using the techbook-pdf build script.
