#What it does
The PPTX skill handles all PowerPoint operations -- creating presentations from scratch, editing existing decks, reading/extracting content, and applying professional design. It emphasizes creating visually striking slides that avoid generic "AI-generated" aesthetics.
#How to use
Activate any time a .pptx file is involved. This includes creating slide decks, pitch decks, reading presentations, editing slides, or working with templates.

#Design Philosophy
Every slide needs a visual element -- text-only slides are forgettable.
Before starting:
- Pick a bold, content-informed color palette specific to the topic
- Use dominance over equality (one color at 60-70% weight)
- Commit to a visual motif and repeat it across every slide
Layout options: Two-column, icon + text rows, 2x2 grids, half-bleed images with content overlay
Typography: Choose interesting font pairings (never default to Arial). Header font with personality, clean body font.
#What to Avoid
- Repeating the same layout across slides
- Centering body text (left-align paragraphs, center only titles)
- Default blue color schemes
- Text-only slides without images, icons, or charts
- Accent lines under titles (hallmark of AI-generated slides)
#Mandatory QA Process
- Content QA: Extract text and verify completeness
- Visual QA: Convert to images and inspect with fresh eyes (sub-agents recommended)
- Fix and re-verify: One fix often creates another problem
- Do not declare success until at least one fix-and-verify cycle is complete
