What problem does it solve? Dense, information-rich Japanese writing often reads as flat and boring because every paragraph is written in the same cognitive mode. This Skill provides a normative rulebook for designing rhythm (緩急) in explanatory prose by deliberately switching the reader's cognitive modes—observation, hesitation, assertion, re-observation—and by managing unresolved tension so readers keep reading. ## Core Features & Use Cases - Sentence and paragraph rhythm design: Defines beat patterns (short setup, long flow, short stop), density waveforms across paragraphs, and rules for alternating assertion with hesitation. - Tension and question management: Keeps at least one unresolved question open, prescribes how to open chapters and sections, land enumerations on concrete scenes, and close by grounding abstractions in the reader's concrete experience. - Mechanical post-draft inspection: Provides a five-step checklist (topic test, vocabulary leakage test, tension ledger, beat check, boundary check) plus a symptom-to-prescription table for diagnosing flat drafts. - Use Case: When a technical article or chapter is accurate but dull, apply the diagnostic table to identify the cause (e.g., theory introduced before the reader feels the problem) and rewrite using the prescribed section-entry and tension-recovery patterns. ## Quick Start Read the attached draft of my Japanese explanatory article and diagnose why it feels flat, then rewrite the opening and section transitions following the cognitive rhythm rules.
