# pptx

A skill that teaches the agent to create, modify and inspect .pptx files: pull text, dig into slide XML, touch notes and comments. Useful when the deck is generated by code instead of PowerPoint clicks.

## What it does

A `.pptx` file is a ZIP of XML parts, and the skill maps that structure out for the agent: presentation metadata in `ppt/presentation.xml`, slides, speaker notes, comments, layouts and theme. Plain text comes out with `python -m markitdown path-to-file.pptx`. Comments, notes, animations and heavy formatting need the archive unpacked: `python ooxml/scripts/unpack.py <office_file> <output_dir>`. The script sits at `skills/pptx/ooxml/scripts/unpack.py` relative to the project root.

For a deck made from scratch, the workflow is html2pptx: slides are authored in HTML and converted to PowerPoint with placement kept accurate. The agent is told to name its design approach before writing any code. Fonts must be web-safe (Arial, Georgia, Courier New among them), and the palette has to fit the subject. Sample palettes and layout tricks such as uneven column widths are included.

Given a reference design, the skill reads it first: colors from `<a:clrScheme>`, fonts from `<a:fontScheme>`, and actual usage in `ppt/slides/slide1.xml`. Python and markitdown are needed for the reading half; without them start there.
