About
The Chapter Briefs skill is a specialized tool for the Codex research pipeline designed to transform flat outlines into cohesive narrative structures. By analyzing H2 chapters and their corresponding H3 subsections, it generates internal 'writing cards' that define synthesis modes, throughlines, and key contrasts. This prevents the 'paragraph island' failure mode common in AI writing, ensuring that chapters read like professional papers with consistent comparison axes rather than disjointed summaries. It is an essential utility for researchers and technical writers who need to maintain high structural integrity in long-form documentation.
