What problem does it solve? Technical documents often mix change history with current state, scatter the same conclusion across multiple files, use undefined identifiers, and assume reader context that no longer exists. This Skill reviews Markdown documentation against five information-organization principles and explains where content belongs, without rewriting prose. ## Core Features & Use Cases - Information Placement Review: Judges whether change history, decision rationale, and current-state statements are correctly separated, and whether introductions serve as reading guides rather than content dumps. - Duplication and Definition Checks: Identifies conclusions defined in multiple places, numbered items used before being defined, and jargon that lacks context for future readers. - Use Case: After drafting a system design document, ask for a review to find sections where a deprecated plan is referenced by number but never defined, or where the same architectural conclusion is copied into three files and will drift. ## Quick Start Review this Markdown design document and point out any information organization problems such as duplicated conclusions, undefined identifiers, or change history mixed into the current-state description.
