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 treats pacing not as decoration but as deliberate switching of the reader's cognitive modes (observation, hesitation, assertion, re-observation) and as management of unresolved tension, so explanatory articles and chapters keep readers moving forward. ## Core Features & Use Cases - Rhythm design rules: Defines sentence-level beats (short setup, long flow, short stop), paragraph density waveforms, section openings via counter-questions or confessions, and landing techniques for enumerations. - Tension ledger and junk-sentence detection: Distinguishes productive looseness (sentences that update the situation) from filler (sentences that only narrate the document itself), with explicit deletion and rewriting procedures. - Mechanical post-writing checklist: Provides a five-step inspection covering topic tests, vocabulary leakage tests, tension recovery tracking, beat checks, and boundary checks. - Use Case: When a technical article or chapter is accurate but dull, apply the diagnostic table to map symptoms (uniform tone, cold theory sections, preachy endings) to concrete fixes. ## Quick Start Use the cognitive-rhythm-writing skill to diagnose and revise this Japanese explanatory article so it has pacing and unresolved tension.
