What problem does it solve?
Turn a PDF ebook into a professional Chinese knowledge-summary LaTeX note and rendered PDF. Use when Codex receives a book, paper-like ebook, textbook chapter, scanned PDF, or image-only PDF and must detect whether OCR is needed, preserve and reuse the book's figures instead of ignoring them, extract and reorganize the core knowledge points, and deliver a complete summary package with extracted assets and a compiled PDF. Use especially when the user wants key-point summaries, chapter takeaways, exam review notes, memorization-first notes, or a concise knowledge map derived from a PDF.
Core Features & Use Cases
- Inspect PDFs to estimate text coverage and image density and decide if OCR is needed.
- Preserve original visuals (figures, formulas, tables) and extract assets for a complete LaTeX notebook.
- Reconstruct a structured LaTeX document with sections and knowledge boxes, and compile to a final PDF.
- Support dual modes: knowledge-summary and exam-cram, and enable multi-agent workflows for large books.
Quick Start
Provide the PDF path and optional mode; the skill will generate a full LaTeX note package and a rendered PDF.
