Can I edit existing slides without breaking the formatting?

Yes, the skill includes a dedicated OOXML workflow that unpacks the presentation, allows for precise XML edits, and uses a validation script to ensure the file structure remains intact before repacking.

How do I verify the output without opening PowerPoint?

The suite includes a thumbnail generation tool that creates a visual grid of your slides, allowing you to inspect for text overlap, contrast issues, or positioning errors directly in your workspace.

Can it follow my company's specific branding?

Absolutely. The skill can analyze existing theme files and master slides to extract typography (fontScheme) and color schemes (clrScheme) to ensure new content matches your brand identity.

How does the skill handle complex layouts like charts and tables?

The skill uses a hybrid approach: structural layouts are defined in HTML, while complex elements like charts and tables are injected using the PptxGenJS API via a JavaScript bridge.
