What kind of output does the X-Ray Book skill produce?

It generates a comprehensive Org-mode (.org) file containing a structured report, ASCII conceptual maps, and a 'Napkin' summary (formula and diagram).

Do I need to provide the full text of the book?

No, you can simply provide a book title. The skill uses web search to gather the core arguments and structure needed for the extraction process.

What is the Epiplexity principle used in this skill?

It is the insight that information is relative to 'cognitive compute.' By investing more analysis (compute), content that seems like 'noise' is transformed into 'learnable structure.'

How do I trigger this skill in Claude Code?

You can use the command /ljg-xray-book followed by the book title, a URL, or the book's content.

Learning & Documentation

Extracts deep learnable structures from books using multi-stage cognitive compression and the Epiplexity principle.

LJG-Xray-Book is a sophisticated knowledge extraction tool designed to maximize your cognitive ROI on reading. Based on the Epiplexity principle—the idea that information clarity is a result of applied computational effort—this skill performs three intensive rounds of analysis on any book. It scans the global skeleton, dissects logical chains and hidden assumptions, and extracts the 'soul' or cross-domain applications. The process concludes with a hyper-compressed 'Napkin' summary featuring ASCII diagrams and core formulas, automatically saved as a structured Org-mode report for your personal knowledge base.
