This gives Claude the ability to read, create, and edit PowerPoint presentations by working with the underlying OOXML format. It includes two main workflows: converting presentations to markdown for quick text extraction, or unpacking the raw XML structure to access speaker notes, comments, layouts, and formatting details. For creating new presentations, it uses an html2pptx approach that converts HTML slides to PowerPoint with accurate positioning. The skill comes with detailed guidance on typography, color palette selection (including 18 different preset combinations), and layout patterns like diagonal dividers and asymmetric columns. It's opinionated about design, requiring you to explain your visual choices before generating slides rather than defaulting to generic corporate blue.
