How does it handle slide design and styling?

It uses an html2pptx workflow where slides are designed using HTML/CSS for precise control, supporting web-safe fonts, custom color palettes, and flexible grid layouts.

Can this skill edit existing PowerPoint files?

Yes, the skill provides tools to unpack .pptx archives, modify the raw OOXML files (including notes and layouts), and repackage them into valid presentations.

How do I ensure the generated slides look correct?

The skill includes a visual validation step that generates a thumbnail grid of the presentation, allowing you to check for text overlaps, contrast issues, or layout errors before final use.

Does it support adding diagrams or charts?

Yes, it integrates with the scientific-schematics skill to generate AI-powered diagrams and supports PptxGenJS for adding native charts and tables.
