slides

--- name: slides description: 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. --- # 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. 2. Set the slide size up front. Default to 16:9 (`LAYOUT_WIDE`) unless the source material clearly uses another aspect ratio. 3. Copy `assets/pptxgenjs_helpers/` into the working directory and import the helpers from there. 4. Build the deck in JavaScript with an explicit theme font, stable spacing, and editable PowerPoint-native elements when practical. 5. Run the bundled scri [... prompt truncated for preview ...]
