How does the skill handle complex content like math equations?

It includes a dedicated LaTeX-to-SVG helper that converts mathematical notation into high-quality vector assets for clear presentation on slides.

Are the generated presentations editable in Microsoft PowerPoint?

Yes, the skill prioritizes native PowerPoint elements—such as text boxes, shapes, and charts—rather than flat images, allowing for full manual editing after generation.

How do I ensure my content doesn't overflow the slide edges?

The skill includes validation scripts like slides_test.py and built-in JavaScript helpers that check for out-of-bounds elements and unintentional overlaps before delivery.

Can I use this skill to update an existing PowerPoint deck?

Absolutely. The skill can inspect existing decks, match their aspect ratio and style, and perform edits while preserving the overall design integrity.

What technologies does this skill use to generate slides?

The skill uses PptxGenJS for authoring slides in JavaScript, ensuring the output is a native .pptx file. It also utilizes Python scripts for rendering previews and performing layout validation.
