1	# PPTX creation, editing, and analysis
2
3	## Overview
4
5	A user may ask you to create, edit, or analyze the contents of a .pptx file. A .pptx file is essentially a ZIP archive containing XML files and other resources that you can read or edit. You have different tools and workflows available for different tasks.
6
7	## Prerequisites
8
9	Python dependencies are resolved automatically by `uv run` — scripts declare them in PEP 723 headers. The workflows below also rely on:
10
11	- Node.js packages — if `node_modules/` is missing, run `npm install` in this skill directory once. This installs `pptxgenjs` and `playwright`, which drives Chromium/Chrome for HTML rendering (on macOS it uses system Chrome; elsewhere run `npx playwright install chromium` once if no browser is present). It also installs `sharp`, `react`, `react-dom`, and `react-icons` — html2pptx.js does not use these itself; they are provided for scripts you write during the html2pptx workflow (icon and gradient rasterization, see [html2pptx.md](html2pptx.md))
12	- LibreOffice (`brew install --cask libreoffice`) and poppler (`brew install poppler`) — converting presentations to PDF/images for thumbnails and visual validation (`soffice`, `pdftoppm`)
13
14	## Reading and analyzing content
15
16	### Text extraction
17	If you just need to read the text contents of a presentation, you should convert the document to markdown:
18
19	```bash
20	# Convert document to markdown
21	uv run --with 'markitdown[pptx]' python -m markitdown path-to-file.pptx
22	```
23
24	### Raw XML access
25	You need raw XML access for: comments, speaker notes, slide layouts, animations, design elements, and complex formatting. For any of these features, you'll need to unpack a presentation and read its raw XML contents.
26
27	#### Unpacking a file
28	`uv run ooxml/scripts/unpack.py <office_file> <output_dir>`
29
30	Note: Run this from the pptx skill directory, where the script is at `ooxml/scripts/unpack.py`. If it isn't found there, use `find . -name "unpack.py"` to locate it.
31
32	#### Key file structures
33	* `ppt/presentation.xml` - Main presentation metadata and slide references
34	* `ppt/slides/slide{N}.xml` - Individual slide contents (slide1.xml, slide2.xml, etc.)
35	* `ppt/notesSlides/notesSlide{N}.xml` - Speaker notes for each slide
36	* `ppt/comments/modernComment_*.xml` - Comments for specific slides
37	* `ppt/slideLayouts/` - Layout templates for slides
38	* `ppt/slideMasters/` - Master slide templates
39	* `ppt/theme/` - Theme and styling information
40	* `ppt/media/` - Images and other media files
41
42	#### Typography and color extraction
43	When given an example design to emulate: Always analyze the presentation's typography and colors first using the methods below:
44	1. Read theme file: Check `ppt/theme/theme1.xml` for colors (`<a:clrScheme>`) and fonts (`<a:fontScheme>`)
45	2. Sample slide content: Examine `ppt/slides/slide1.xml` for actual font usage (`<a:rPr>`) and colors
46	3. Search for patterns: Use grep to find color (`<a:solidFill>`, `<a:srgbClr>`) and font references across all XML files
47
48	## Creating a new PowerPoint presentation without a template
49
50	When creating a new PowerPoint presentation from scratch, use the html2pptx workflow to convert HTML slides to PowerPoint with accurate positioning.
51
52	### Design Principles
53
54	CRITICAL: Before creating any presentation, analyze the content and choose appropriate design elements:
55	1. Consider the subject matter: What is this presentation about? What tone, industry, or mood does it suggest?
56	2. Check for branding: If the user mentions a company/organization, consider their brand colors and identity
57	3. Match palette to content: Select colors that reflect the subject
58	4. State your approach: Explain your design choices before writing code
59
60	Requirements:
61	- ✅ State your content-informed design approach BEFORE writing code
62	- ✅ Use web-safe fonts only: Arial, Helvetica, Times New Roman, Georgia, Courier New, Verdana, Tahoma, Trebuchet MS, Impact
63	- ✅ Create clear visual hierarchy through size, weight, and color
64	- ✅ Ensure readability: strong contrast, appropriately sized text, clean alignment
65	- ✅ Be consistent: repeat patterns, spacing, and visual language across slides
66
67	#### Color Palette Selection
68
69	Choosing colors creatively:
70	- Think beyond defaults: What colors genuinely match this specific topic? Avoid autopilot choices.
71	- Consider multiple angles: Topic, industry, mood, energy level, target audience, brand identity (if mentioned)
72	- Be adventurous: Try unexpected combinations - a healthcare presentation doesn't have to be green, finance doesn't have to be navy
73	- Build your palette: Pick 3-5 colors that work together (dominant colors + supporting t
