# PPTX Skill

## Tool-First Workflow

Use the `Presentation` tool for ALL operations. Do NOT use Python scripts unless you need features the tool doesn't have.

### Available Presentation tool actions

| Task | Tool call |
|------|-----------|
| Inspect metadata | `Presentation { action: "inspect", file_path: "deck.pptx" }` |
| List all slides | `Presentation { action: "list_slides", file_path: "deck.pptx" }` |
| Extract text (all or one slide) | `Presentation { action: "extract_text", file_path: "deck.pptx" }` |
| Read speaker notes | `Presentation { action: "read_notes", file_path: "deck.pptx" }` |
| Export text outline | `Presentation { action: "export_text_outline", file_path: "deck.pptx" }` |
| **Create new presentation** | `Presentation { action: "create", output_path: "deck.pptx", content: {slides: [{title, body: [...]}]} }` |
| **Unpack for XML editing** | `Presentation { action: "unpack", file_path: "deck.pptx", output_path: "unpacked/" }` |
| **Repack after editing** | `Presentation { action: "pack", file_path: "unpacked/", output_path: "output.pptx" }` |

### Editing an existing presentation

```
Presentation { action: "unpack", file_path: "template.pptx", output_path: "/tmp/unpacked/" }
# → Edit slide XML files in /tmp/unpacked/ppt/slides/ with the Edit tool
# → Reorder slides by editing /tmp/unpacked/ppt/presentation.xml
Presentation { action: "pack", file_path: "/tmp/unpacked/", output_path: "output.pptx" }
```

### Creating from scratch

```
Presentation { action: "create", output_path: "deck.pptx", content: {
  "layout": "16x9",
  "slides": [
    {"title": "Welcome", "body": ["Point 1", "Point 2", "Point 3"]},
    {"title": "Details", "body": ["Item A", "Item B"], "notes": "Speaker notes here"}
  ]
}}
```

For advanced presentations (charts, images, custom layouts), use PptxGenJS via Bash — see [pptxgenjs.md](pptxgenjs.md).

### When to fall back to Python
- Thumbnail grids (requires LibreOffice + PIL)
- Converting PPTX to PDF (requires LibreOffice)

## Quick Reference (LEGACY — prefer Presentation tool above)

| Task | Guide |
|------|-------|
| Read/analyze content | `Presentation { action: "extract_text" }` |
| Edit or create from template | `Presentation { action: "unpack" }` → Edit → `Presentation { action: "pack" }` |
| Create from scratch | PptxGenJS via Bash (see [pptxgenjs.md](pptxgenjs.md)) |

---

## Reading Content (LEGACY)

```bash
# Visual overview (requires LibreOffice + PIL — use only if needed)
python scripts/thumbnail.py presentation.pptx
```

## Editing Workflow

**Read [editing.md](editing.md) for full details.**

1. Analyze template:
   ```
   Presentation { action: "list_slides", file_path: "template.pptx" }
   Presentation { action: "extract_text", file_path: "template.pptx" }
   ```
2. Unpack → manipulate slides XML → edit content → pack:
   ```
   Presentation { action: "unpack", file_path: "template.pptx", output_path: "/tmp/unpacked/" }
   # Edit XML with the Edit tool
   Presentation { action: "pack", file_path: "/tmp/unpacked/", output_path: "output.pptx" }
   ```

## Creating from Scratch

**Read [pptxgenjs.md](pptxgenjs.md) for full details.**

Use when no template or reference presentation is available.

## Design Ideas

**Don't create boring slides.** Plain bullets on a white background won't impress anyone. 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) |
