Create and edit presentation slide decks (`.pptx`) with PptxGenJS, bundled layout helpers, and render/validation utilities. Use when tasks involve building a new PowerPoint deck, recreating slides from screenshots/PDFs/reference decks, modifying slide content while preserving editable output, adding charts/diagrams/visuals, or diagnosing layout issues such as overflow, overlaps, and font substitution.
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
# Slides
## Overview
Use PptxGenJS for slide authoring. Do not use `python-pptx` for deck generation unless the task is inspection-only; keep editable output in JavaScript and deliver both the `.pptx` and the source `.js`.
Keep work in a task-local directory. Only copy final artifacts to the requested destination after rendering and validation pass.
## Bundled Resources
- `assets/pptxgenjs_helpers/`: Copy this folder into the deck workspace and import it locally instead of reimplementing helper logic.
- `scripts/render_slides.py`: Rasterize a `.pptx` or `.pdf` to per-slide PNGs.
- `scripts/slides_test.py`: Detect content that overflows the slide canvas.
- `scripts/create_montage.py`: Build a contact-sheet style montage of rendered slides.
- `scripts/detect_font.py`: Report missing or substituted fonts as LibreOffice resolves them.
- `scripts/ensure_raster_image.py`: Convert SVG/EMF/HEIC/PDF-like assets into PNGs for quick inspection.
- `references/pptxgenjs-helpers.md`: Load only when you need API details or dependency notes.
## Workflow
1. Inspect the request and determine whether you are creating a new deck, recreating an existing deck, or editing one.

The line at the top of this page pins the label git:20260422.d32735f, 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.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
