pptx

Create a .pptx that opens in PowerPoint, Keynote, LibreOffice Impress and Google Slides, or read an existing deck so its content can be summarised or reused. No extra packages: the script builds the OOXML package itself.

This skill is original to Synaplan Desktop (Apache-2.0). It is not Anthropic's document skill.

When to use

• The user asks for a PowerPoint deck, .pptx, or slides that open in PowerPoint.
• For a browser slideshow instead, use the slides skill.
• The user has .pptx files in an allowed folder and wants their text (read them first, then write the new deck or document).

How to run

Write: first save the outline with write_file into the out-box, then

python3 <skill_dir>/run.py write <outline.md> <output.pptx>

Read (Markdown out, so you can read_file it):

python3 <skill_dir>/run.py read <input.pptx> <output.md>

• <output.pptx> / <output.md> — paths inside the out-box.
• <input.pptx> — a deck in an allowed folder or in the out-box.

Outline the writer understands

# Deck title
One line under it becomes the subtitle.   (this IS the title slide — do not
                                            add a slide called "Title slide")

## Slide title
- bullet (keep to about six per slide)
  - sub-bullet
| Region | Units |         a Markdown table becomes a native PowerPoint table
| --- | --- |
| North | 1,320 |

A chart on the right half of a slide (same block as the docx skill):

```chart
type: bar            (bar | line | pie)
title: Organisations using AI (%)
categories: Finance, Health, Retail
series: 2024: 38, 22, 30
series: 2026: 61, 41, 52
```

Standard library only. After the script exits 0, tell the user the full path.
