Use this Canvas-owned clean-room skill whenever a PowerPoint `.pptx` deck is an input or output. Trigger for creating, editing, reviewing, repairing, templating, combining, splitting, rendering, or extracting slide decks, including pitch decks, reports, speaker notes, template-following, and Google Slides-targeted handoff.

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 Presentations

This skill covers editable PowerPoint-compatible presentation work in Canvas
Notebook. It is a clean-room Canvas skill; do not copy vendor skill material,
hidden prompts, or proprietary helper code into this folder.

## Core Contract

- Use `CANVAS_AGENT_TEMP_DIR` for scripts, working copies, exported PDFs,
  thumbnails, and QA images. Promote only the requested final deck to the
  workspace with `copy_path` or `move_path`.
- Deliver editable slides: use PowerPoint-native text, shapes, tables, charts,
  images, speaker notes, and layouts. Full-slide bitmaps are acceptable only
  when the user explicitly asks for image-only slides.
- Preserve source deck styling for targeted edits and template-following tasks.
- For new decks, choose a coherent visual system before building: type scale,
  palette, grid, slide rhythm, image treatment, chart style, and footer/page
  conventions.
- Keep scratch exports, thumbnails, notes, and QA images out of the final
  response unless requested.
- Use stable descriptive filenames and write final decks to the requested path
  or the workspace.

## Recommended Tools

- `python-pptx` for creating and editing many deck structures.

How to install

The exact contents, by fingerprint

mdr add canvascoding/canvas-notebook/pptx@sha256:754f0fcf1f45af29

The line at the top of this page pins the label git:20260908.d687d43, 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.
