pptx
Use this skill any time a .pptx or .potx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx or .potx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates (.potx), layouts, speaker notes, or comments. Trigger whenever the user mentions "deck," "slides," "presentation," or references a .pptx or .potx filename, regardless of what they plan to do with the content afterward. If a .pptx or .potx file needs to be opened, created, or touched, use this skill.

PPTX creation, editing, and analysis A .pptx is a ZIP archive of XML files. Choose your approach by task: | Task | Approach | |---|---| | Create a new deck | Write a pptxgenjs script — see gotchas below | | Edit an existing deck, or build from a template | unzip → edit ppt/slides/slideN.xml → zip | | Read content | markitdown deck.pptx (one block per slide under markers); visual grid: python scripts/thumbnail.py deck.pptx | Scripts Paths are relative to this skill's directory. Everything else is plain Python, node, or shell. | Script | What it does | |---|---| | scripts/thumbnail.py deck.pptx [prefix] | Labeled grid of every slide, for picking template layouts. .pptx only. Pass prefix — it defaults to thumbnails, which overwrites the grids of any other deck done in the same directory | | scripts/addslide.py unpacked/ slide2.xml [--after slideN.xml] | Duplicate a slide (or a slideLayoutN.xml) with all the package bookkeeping.
