What problem does it solve? Long analytical or theoretical documents often reuse key concepts whose meaning quietly shifts between sections, creating hidden contradictions, unjustified scope expansions, or level confusions that undermine the argument. This Skill provides a structured method to detect those conceptual instabilities without imposing external definitions on the author's work. ## Core Features & Use Cases - Concept Tracking: Identify structurally important concepts and compare their meaning and function across passages and sections. - Drift and Contradiction Detection: Flag semantic expansion, category shifts, level confusion, and genuine inconsistencies while distinguishing them from productive tension or contextual variation. - Evidence-Based Findings: Produce structured reports citing the concept, relevant passages, the specific shift, why it matters, and a confidence level. - Use Case: A researcher reviewing a philosophy manuscript uses this Skill to verify that a term like 'emergence' keeps a stable analytical role from the introduction through the conclusion, and receives a cited list of passages where its scope silently broadened. ## Quick Start Analyze the attached manuscript for conceptual consistency and report any concepts whose meaning or function shifts across sections.
