How does it handle technical jargon?

The skill follows a 'zero-term rule' where technical concepts must be explained using real-world scenarios (like group chats or navigation) before the technical name is even introduced.

Does this skill work with PDF files?

Yes, it can process local PDF paths and URLs. It specifically optimizes Arxiv links by converting them to HTML for better text extraction and analysis.

What are Cognitive Delta Cards?

They are ASCII-based visual representations (charts or topologies) that show how a paper's insights specifically change your existing thinking, decision habits, or cognitive blind spots.

What is the cognitive baseline feature?

The skill reads your local soul.md and memory.md files to understand your current worldview and beliefs, ensuring the analysis is personally relevant to your existing knowledge.

Learning & Documentation

Deconstructs academic papers into simplified summaries and visualizes cognitive insights using ASCII art and personal knowledge baselines.

LJG Paper X-ray is a specialized Claude Code skill designed to strip away academic jargon and extract the core essence of research papers. It follows a rigorous process of 'problem-perspective-result' analysis while mapping new information against a user's existing cognitive baseline defined in local files. By transforming complex technical concepts into relatable real-world scenarios and 'napkin' ASCII diagrams, it helps researchers and lifelong learners identify the 'cognitive delta'—the specific ways a paper changes their thinking or decision-making patterns. The skill outputs structured Org-mode reports compatible with the Denote system for long-term knowledge management.
