What problem does it solve? Generated documents often look generic: default fonts, walls of bullets, rainbow charts, and repeated identical sections. This Skill provides design rules so reports, proposals, decks, and briefs read as deliberately designed rather than machine-produced. ## Core Features & Use Cases - Typography and colour law: Enforces three-role font pairing, real size contrast, 60-75 character line lengths, and a one-accent colour budget for .docx, .pptx, .pdf, and Markdown deliverables. - Structure and prose discipline: Requires numbered sections, running heads, executive summaries, prose over bullet soup, and tables with no vertical rules or zebra striping. - Pre-delivery checklist: Runs squint, line-length, accent, bullet, and greyscale audits before shipping. - Use Case: When generating a quarterly business review deck, apply these rules so each slide states its takeaway as the title, uses one accent colour, and avoids clip-art and bullet overload. ## Quick Start Apply the document-design rules to format this quarterly report as a polished PDF deliverable.
