How is visual quality guaranteed?

The skill employs a verification loop where slides are converted to images and inspected by subagents to catch overlapping elements, layout shifts, or text overflows.

How does this skill handle existing PowerPoint templates?

It uses a specialized editing workflow involving thumbnail analysis and XML manipulation to preserve and update existing layouts while ensuring content fits the template.

Can I create slides without an existing file?

Yes, the skill includes a 'Create from Scratch' path using the pptxgenjs library for programmatic generation when no template is available.

Does it support extracting text from slides?

Yes, it utilizes Markitdown for high-quality text extraction and parsing of presentation content to be used in summaries or other documents.

How does the skill ensure slides don't look 'AI-generated'?
