Overview

The Pptx Generator skill is a security-tested data-ai capability for Claude AI, graded B. It generates, edits, and reads PowerPoint presentations (.pptx) using PptxGenJS and markitdown. The skill allows creating presentations from scratch with a comprehensive design system, including cover, table of contents, content, section divider, and summary slides. It also supports editing existing presentations via XML workflows and extracting text with markitdown. The skill provides detailed guidance for slide types, color palettes, fonts, and style recipes, making it suitable for users who need to automate PowerPoint tasks. The skill's workflow for creating presentations from scratch involves researching user requirements, selecting a color palette and fonts, choosing a design style, planning the slide outline, generating slide JS files, and compiling them into a final PPTX. It supports up to 5 concurrent slide generations using subagents. The Pptx Generator skill is licensed under MIT and utilizes PptxGenJS and markitdown as sources.
