Can this skill edit existing PowerPoint files?

Yes, it uses an OOXML workflow to unpack .pptx files, edit the raw XML content (including slides, notes, and layouts), and repackage them while preserving document integrity.

How does it handle slide design and layout?

The skill utilizes an html2pptx workflow that converts HTML/CSS structures into PowerPoint shapes, allowing for precise control over positioning, typography, and color schemes.

How do I ensure the generated slides look correct?

The skill includes a mandatory visual validation step that generates thumbnail images of the slides, allowing Claude to inspect for text cutoff, overlaps, and contrast issues before finalizing the file.
