The instructions your model reads when the skill loads.
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.
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
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.
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.
