Pptx

This gives Claude full PowerPoint capabilities through direct XML manipulation of the OOXML format. It handles the complete workflow: extracting text with markitdown for simple reads, unpacking the ZIP structure to access raw XML for complex edits (comments, speaker notes, layouts, animations), and creating new presentations via an html2pptx converter that renders HTML slides to PowerPoint with accurate positioning. The most interesting part is the opinionated design guidance baked into the instructions. It pushes Claude to choose color palettes based on subject matter rather than defaults, provides 18 example schemes ranging from "Classic Blue" to "Retro Rainbow," and includes specific layout patterns like asymmetric columns and Z-pattern flows. If you're building presentation workflows or need programmatic PPTX control, this beats the typical "just use the API" approach.
