presentation is a skill for Claude Code from aisa-group/promptinject-agent-skills. It costs 62 tokens per session (6,309 once invoked), scanned B, a copy of pptx, MIT.

A toolkit for creating, editing, and examining PowerPoint presentations in .pptx format. It covers slide content, layouts, speaker notes, comments, animations, and other presentation details.

In plain words
What is it for?
Use it to create or modify presentations, adjust layouts, add notes or comments, inspect slide structure, and analyze existing .pptx files.
Why use it?
It provides workflows for both ordinary slide edits and the underlying presentation files needed for complex formatting. This helps inspect or change details that are not visible in the main slide text.

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 B, and why

presentation scanned grade B with 1 finding 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 2mo 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.

A mod that escalates privileges can change anything on the machine, not only the project.

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.

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
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

python ooxml/scripts/unpack.py <office_file> <output_dir>

Note: The unpack.py script is located at skills/pptx/ooxml/scripts/unpack.py relative to the project root. If the script doesn't exist at this path, 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
Typography and color extraction

When given an example design to emulate: Always analyze the presentation's typography and colors first using the methods below:

  1. Read theme file: Check ppt/theme/theme1.xml for colors (<a:clrScheme>) and fonts (<a:fontScheme>)
  2. Sample slide content: Examine ppt/slides/slide1.xml for actual font usage (<a:rPr>) and colors
  3. Search for patterns: Use grep to find color (<a:solidFill>, <a:srgbClr>) and font references across all XML files

What ships with it

60 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.
