This file is byte-identical to the first copy the registry indexed, one of 7 indexed copies. Same content hash, so the same checks give both the same grade.
pptx from frankxai/claude-skills-library is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
Presentation creation, editing, and analysis. When Claude needs to work with presentations (.pptx files) for: (1) Creating new presentations, (2) Modifying or editing content, (3) Working with layouts, (4) Adding comments or speaker notes, or any other presentation tasks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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:
```bash
# 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

The line at the top of this page pins the label git:20260525.468c26e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
