Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pptx scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

The scan reads SKILL.md. This mod also ships 13 executable files (ooxml/scripts/pack.py, ooxml/scripts/unpack.py, ooxml/scripts/validate.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

PPTX creation, editing, and analysis

Overview

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.

Prerequisites

Python dependencies are resolved automatically by uv run — scripts declare them in PEP 723 headers. The workflows below also rely on:

  • 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)
  • LibreOffice (brew install --cask libreoffice) and poppler (brew install poppler) — converting presentations to PDF/images for thumbnails and visual validation (soffice, pdftoppm)

Reading and analyzing content

Text extraction

If you just need to read the text contents of a presentation, you should convert the document to markdown:

# Convert document to markdown
uv run --with 'markitdown[pptx]' python -m markitdown path-to-file.pptx

Raw XML access

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.

Unpacking a file

uv run ooxml/scripts/unpack.py <office_file> <output_dir>

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.

Key file structures
  • ppt/presentation.xml - Main presentation metadata and slide references
  • ppt/slides/slide{N}.xml - Individual slide contents (slide1.xml, slide2.xml, etc.)
  • ppt/notesSlides/notesSlide{N}.xml - Speaker notes for each slide
  • ppt/comments/modernComment_*.xml - Comments for specific slides
  • ppt/slideLayouts/ - Layout templates for slides
  • ppt/slideMasters/ - Master slide templates
  • ppt/theme/ - Theme and styling information
  • ppt/media/ - Images and other media files

What ships with it

56 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
