LICENSE.txt has complete terms +platforms: [linux, macos, windows] +--- + +# Powerpoint Skill + +## When to use + +Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions "deck," "slides," "presentation," or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill. + +## Quick Reference + +| Task | Guide | +|------|-------| +| Read/analyze content | `python -m markitdown presentation.pptx` | +| Edit or create from template | Read [editing.md](editing.md) | +| Create from scratch | Read [pptxgenjs.md](pptxgenjs.md) | + +--- + +## Reading Content + +```bash +# Text extraction +python -m markitdown presentation.pptx + +# Visual overview +python scripts/thumbnail.py presentation.pptx + +# Raw XML +python scripts/office/unpack.py presentation.pptx unpacked/ +``` + +--- + +## Editing Workflow + +**Read [editing.md](editing.md) for full details.** + +1.

Consider ideas from this list for each slide. + +### Before Starting + +- **Pick a bold, content-informed color palette**: The palette should feel designed for THIS topic. If swapping your colors into a completely different presentation would still "work," you haven't made specific enough choices. +- **Dominance over equality**: One color should dominate (60-70% visual weight), with 1-2 supporting tones and one sharp accent. Never give all colors equal weight. +- **Dark/light contrast**: Dark backgrounds for title + conclusion slides, light for content ("sandwich" structure). Or commit to dark throughout for a premium feel. +- **Commit to a visual motif**: Pick ONE distinctive element and repeat it — rounded image frames, icons in colored circles, thick single-side borders. Carry it across every slide. + +### Color Palettes + +Choose colors that match your topic — don't default to generic blue. Use these palettes as inspiration: + +| Theme | Primary | Secondary | Accent | +|-------|---------|-----------|--------| +| **Midnight Executive** | `1E2761` (navy) | `CADCFC` (ice blue) | `FFFFFF` (white) | +| **Forest & Moss** | `2C5F2D` (forest) | `97BC62` (moss) | `F5F5F5` (cream) | +| **Coral Energy** | `F96167` (coral) | `F9E795` (gold) | `2F3C7E` (navy) | +| **Warm Terracotta** | `B85042` (terracotta) | `E7E8D1` (sand) | `A7BEAE` (sage) | +| **Ocean Gradient** | `065A82` (deep blue) | `1C7293` (teal) | `21295C` (midnight) | +| **Charcoal Minimal** | `36454F` (charcoal) | `F2F2F2` (off-white) | `212121` (black) | +| **Teal Trust** | `028090` (teal) | `00A896` (seafoam) | `02C39A` (mint) | +| **Berry & Cream** | `6D2E46` (berry) | `A26769` (dusty rose) | `ECE2D0` (cream) | +| **Sage Calm** | `84B59F` (sage) | `69A297` (eucalyptus) | `50808E` (slate) | +| **Cherry Bold** | `990011` (cherry) | `FCF6F5` (off-white) | `2F3C7E` (navy) | + +### For Each Slide + +**Every slide needs a visual element** — image, chart, icon, or shape. Text-only slides are forgettable. + +**Layout options:** +- Two-column (text left, illustration on right) +- Icon + text rows (icon in colored circle, bold header, description below) +- 2x2 or 2x3 grid (image on one side, grid of content blocks on other) +- Half-bleed image (full left or right side) with content overlay + +**Data display:** +- Large stat callouts (big numbers 60-72pt with small labels below) +- Comparison columns (before/after, pros/cons, side-by-side options) +- Timeline or process flow (numbered steps, arrows) + +**Visual polish:** +- Icons in small colored circles next to section headers +- Italic accent text for key stats or taglines + +### Typography + +**Choose an interesting font pairing** — don't default to Arial. Pick a header font with personality and pair it with a clean body font. + +| Header Font | Body Font | +|-------------|-----------| +| Georgia | Calibri | +| Arial Black | Arial | +| Calibri | Calibri Light | +| Cambria | Calibri | +| Trebuchet MS | Calibri | +| Impact | Arial | +| Palatino | Garamond | +| Consolas | Calibri | + +| Element | Size | +|---------|------| +| Slide title | 36-44pt bold | +| Section header | 20-24pt bold | +| Body text | 14-16pt | +| Captions | 10-12pt muted | + +### Spacing + +- 0.5" minimum margins +- 0.3-0.5" between content blocks +- Leave breathing room—don't fill every inch + +### Avoid (Common Mistakes) + +- **Don't repeat the same layout** — vary columns, cards, and callouts across slides +- **Don't center body text** — left-align paragraphs and lists; center only titles +- **Don't skimp on size contrast** — titles need 36pt+ to stand out from 14-16pt body +- **Don't default to blue** — pick colors that reflect the specific topic +- **Don't mix spacing randomly** — choose 0.3" or 0.5" gaps and use consistently +- **Don't style one slide and leave the rest plain** — commit fully or keep it simple throughout +- **Don't create text-only slides** — add images, icons, charts, or visual elements; avoid plain title + bullets +- **Don't forget text box padding** — when aligning lines or shapes with text edges, set `margin: 0` on the text box or offset the shape to account for padding +- **Don't use low-contrast elements** — icons AND text need strong contrast against the background; avoid light text on light backgrounds or dark text on dark backgrounds +- **NEVER use accent lines under titles** — these are a hallmark of AI-generated slides; use whitespace or background color instead + +--- + +## QA (Required) + +**Assume there are problems. Your job is to find them.** + +Your first render is almost never correct. Approach QA as a bug hunt, not a confirmation step. If you found zero issues on first inspection, you weren't looking hard enough. + +### Content QA + +```bash +python -m markitdown output.pptx +``` + +Check for missing content, typos, wrong order. + +**When using templates, check for leftover placeholder text:** + +```bash +python -m markitdown output.pptx | grep -iE "xxxx|lorem|ipsum|this.*(page|slide).*layout" +``` + +If grep returns results, fix them before declaring success. + +### Visual QA + +**⚠️ USE SUBAGENTS** — even for 2-3 slides. You've been staring at the code and will see what you expect, not what's there. Subagents have fresh eyes. + +Convert slides to images (see [Converting to Images](#converting-to-images)), then use this prompt: + +``` +Visually inspect these slides. Assume there are issues — find them. + +Look for: +- Overlapping elements (text through shapes, lines through words, stacked elements) +- Text overflow or cut off at edges/box boundaries +- Decorative lines positioned for single-line text but title wrapped to two lines +- Source citations or footers colliding with content above +- Elements too close (< 0.3" gaps) or cards/sections nearly touching +- Uneven gaps (large empty area in one place, cramped in another) +- Insufficient margin from slide edges (< 0.5") +- Columns or similar elements not aligned consistently +- Low-contrast text (e.g., light gray text on cream-colored background) +- Low-contrast icons (e.g., dark icons on dark backgrounds without a contrasting circle) +- Text boxes too narrow causing excessive wrapping +- Leftover placeholder content + +For each slide, list issues or areas of concern, even if minor. + +Read and analyze these images: +1. /path/to/slide-01.jpg (Expected: [brief description]) +2. /path/to/slide-02.jpg (Expected: [brief description]) + +Report ALL issues found, including minor ones. +``` + +### Verification Loop + +1. Generate slides → Convert to images → Inspect +2. **List issues found** (if none found, look again more critically) +3. Fix issues +4. **Re-verify affected slides** — one fix often creates another problem +5. Repeat until a full pass reveals no new issues + +**Do not declare success until you've completed at least one fix-and-verify cycle.** + +--- + +## Converting to Images + +Convert presentations to individual slide images for visual inspection: + +```bash +python scripts/office/soffice.py --headless --convert-to pdf output.pptx +pdftoppm -jpeg -r 150 output.pdf slide +``` + +This creates `slide-01.jpg`, `slide-02.jpg`, etc. + +To re-render specific slides after fixes: + +```bash +pdftoppm -jpeg -r 150 -f N -l N output.pdf slide-fixed +``` + +--- + +## Dependencies + +- `pip install "markitdown[pptx]"` - text extraction +- `pip install Pillow` - thumbnail grids +- `npm install -g pptxgenjs` - creating from scratch +- LibreOffice (`soffice`) - PDF conversion (auto-configured for sandboxed environments via `scripts/office/soffice.py`) +- Poppler (`pdftoppm`) - PDF to images
