What is deep-reading-coach?

Deep Reading Coach is a skill for Codex, an AI coding and task assistant, that helps you read books and PDF documents more carefully and systematically. Rather than just summarizing what you give it, it acts as a structured reading guide that adapts its approach based on what you actually want to get out of a document. The README is written primarily in Chinese and draws heavily on the methodology from the Chinese translation of "How to Read a Book" by Mortimer Adler. The skill supports four main modes. The first, called Quick Preview, gives you a fast orientation: it tells you what a book is about, who it is for, which chapters are worth reading closely, and helps you decide whether to continue. The second mode, Deep Breakdown, is a full analytical reading that maps the author's central question and argument structure, identifies key terms and propositions, and builds a complete reading outline. The third mode, Thematic Research, lets you compare several books or articles on a single topic, building a neutral shared vocabulary and mapping where different sources agree or disagree. The fourth mode, Reading Plan, helps you when you have limited time, producing a schedule with priorities for which sections to read closely and which to skim. The skill also includes Python helper scripts for working with PDF files. One script diagnoses whether a PDF can be read as text or is a scanned image version. Others handle OCR using Windows built-in tools, Tesseract, or AI vision models for difficult scans. Installation means placing the entire skill folder in the Codex user skills directory (a specific path under your user profile), then restarting Codex so it loads the new skill. The README notes that the scripts folder must be included alongside the main skill definition file, since the PDF processing tools are part of how the skill works.
