How does this skill handle design and branding?

It includes curated color palettes and design principles that guide Claude to create professional visual hierarchies, ensuring high contrast, web-safe typography, and consistent layouts.

How can I verify the layout before finishing?

The skill provides a thumbnail generation script that creates a visual grid of all slides, allowing you to inspect for text cutoff, overlapping elements, or contrast issues.

Can I edit existing PowerPoint files without losing formatting?

Yes, the skill uses a direct OOXML editing workflow to unpack the .pptx archive, modify specific XML elements like text or layouts, and repack the file while preserving the original styles.

Can it generate charts and tables programmatically?

Yes, it integrates with the PptxGenJS API to programmatically insert data-driven charts and tables into designated slide placeholders.

What technical stack is used for slide creation?

The skill utilizes a combination of Python for XML processing, MarkItDown for text extraction, and a JavaScript-based html2pptx library to convert HTML/CSS designs into native PowerPoint objects.
