The pptx-posters skill empowers Claude to design high-impact research posters using modern web technologies. While LaTeX is the academic standard, this skill is specifically designed for workflows requiring PowerPoint (PPTX) compatibility or visual-first design iteration. It features a standardized HTML/CSS template with fixed dimensions (36x48 inches), professional typography, and a specialized workflow for generating AI-powered visuals. The skill strictly enforces poster-readable font sizes and content density rules to ensure presentations are legible from a distance of 4-6 feet, making it ideal for conference settings where visual clarity is paramount.
