How does this skill create new presentations?

It uses an html2pptx workflow, where Claude creates HTML/CSS representations of slides which are then programmatically converted into native PowerPoint files with accurate positioning.

Can I edit existing PowerPoint files without losing formatting?

Yes, the skill utilizes an OOXML workflow that unpacks the .pptx archive, allows for targeted XML edits to specific slides or notes, and repacks the file while maintaining the original structure.

How does Claude 'see' the slides it creates?

The skill includes a thumbnail generation script that creates a visual grid of the slides, allowing Claude to inspect the layout for text overlaps, contrast issues, or positioning errors.

Does it support company branding and templates?

Absolutely. The skill includes a dedicated workflow for analyzing existing templates, extracting themes, and duplicating slide masters to ensure new content matches your brand identity.
