What problem does it solve? Writers and editors often sense that a passage is weak but cannot name why. This Skill explains the specific mechanical causes behind prose effects — word register, sentence stress positions, rhythm, punctuation logic, and argument structure — so revisions are grounded in technique rather than vague taste. ## Core Features & Use Cases - Diction Analysis: Diagnose Anglo-Saxon vs. Latinate word choice, connotation, register, specificity, and phonesthetic texture (plosives, fricatives, liquids, nasals). - Sentence Mechanics: Apply the Gopen-Swan topic/stress model, cumulative vs. periodic structures, parallelism, and transition logic to control emphasis and rhythm. - Argument Architecture: Structure paragraphs and essays using Toulmin's claim-data-warrant model, classical arrangement, and steel-manned counterargument. - Use Case: Paste a draft paragraph and ask why it feels flat; the Skill identifies that new information is buried mid-sentence instead of in the stress position and that Latinate abstractions replace concrete nouns, then rewrites it accordingly. ## Quick Start Ask the AI to analyze this paragraph's word choice, sentence rhythm, and emphasis using prose mechanics and suggest a revision.
