What does pptx do?
pptx is a Claude skill that creates, edits and reads PowerPoint .pptx and .potx files. New decks are written as pptxgenjs scripts, with a list of pitfalls such as hex colors without #, native charts and speaker notes through addNotes. Existing decks and templates are unzipped, edited slide by slide in the XML and zipped again, using bundled scripts to duplicate slides, clean orphaned parts and validate the file. markitdown pulls the text out. A design section covers palettes, layouts, safe fonts and type sizes. Before finishing, Claude must render the slides to images through LibreOffice and pdftoppm and check them for overflow, overlaps and leftover placeholder text.
