This gives Claude direct XML access to PowerPoint files, which matters when you need to do more than just read slide text. It can unpack .pptx files to edit comments, speaker notes, layouts, and animations at the XML level. The html2pptx workflow is interesting: it converts HTML to PowerPoint with precise positioning, and the docs include 18 preset color palettes plus guidance on matching design choices to content. If you're automating presentation generation or need to manipulate PowerPoint internals programmatically, this handles both the low-level XML surgery and the higher-level template workflows. The design principles section is surprisingly opinionated about typography and layout patterns.
