What problem does it solve? Writers and editors of long, complex texts struggle to distinguish productive repetition from genuine redundancy, often deleting structurally necessary material or retaining duplicated content that weakens the architecture. ## Core Features & Use Cases - Functional Redundancy Audit: Classifies sections, nodes, examples, and definitions as necessary, useful, partially redundant, redundant, or unresolved based on the function each performs rather than surface similarity. - Structural Counterfactual Tests: Applies removal, absorption, merge, relocation, compression, and dependency tests before recommending any deletion or merger. - Use Case: When revising a book-length manuscript with recurring concepts across chapters, use this Skill to determine whether each recurrence develops, transforms, or merely duplicates earlier material, then receive severity-rated findings with concrete recommendations. ## Quick Start Analyze this manuscript and identify which sections are structurally necessary, partially redundant, or genuinely redundant, with evidence and recommendations for each finding.
