SkillForAgentsPPTX
Build and edit PowerPoint decks, including templates, speaker notes, and slide thumbnails.
Like the DOCX skill, PPTX treats a .pptx file as what it actually is — a ZIP archive of XML — and picks its approach accordingly: new decks get built with pptxgenjs, editing an existing deck or working from a .potx template means unzipping and editing the relevant ppt/slides/slideN.xml files directly, and reading content back out uses markitdown to produce one text block per slide, with a separate thumbnail script available when a visual grid of the deck is more useful than raw text.
The skill triggers on any mention of a “deck,” “slides,” or “presentation,” or whenever a .pptx/.potx filename comes up in conversation — whether the file is being created, read, edited, combined, split, or just referenced as a template. That includes working with layouts, speaker notes, and comments, not just slide content.
It’s one of Anthropic’s official document skills (source-available, not open source), released as a reference implementation of the presentation capabilities that power Claude’s own deck-building features.
