Can I edit existing PowerPoint files without breaking them?

Absolutely. The skill includes an OOXML workflow that unpacks the .pptx file, allows for XML-based editing, and runs validation scripts before repacking to ensure file integrity.

How does Claude ensure the slides are visually correct?

The skill includes a visual validation step where Claude generates thumbnail grids of the slides to inspect for text cutoff, overlap, or contrast issues before finalizing the file.

Does this skill support speaker notes and comments?

Yes, by accessing the underlying raw XML files like notesSlide.xml and modernComment.xml, Claude can read, add, or modify speaker notes and slide comments.

Can Claude create presentations from scratch?

Yes, Claude uses a sophisticated html2pptx workflow to design and build professional slides with accurate positioning, custom colors, and web-safe typography.
