PowerPoint

Use this skill whenever a PowerPoint deck is involved. For new decks, pass a trusted PptxGenJS build script directly to the pptx_write tool. For filling or editing an existing template, call pptx_template_analyze first and then pptx_template_fill with the exact IDs returned by analysis.

Workflow

1. Decide the deck outline and choose a visual system: palette, typography, repeated motif, and slide rhythm.
2. Write JavaScript module content that exports default async function build(pptx, ctx) or named build(pptx, ctx).
3. In the script, add slides directly with PptxGenJS. Do not generate HTML for this workflow.
4. Call pptx_write with path, script, optional assets_dir, and optional data.
5. Verify the result with pptx_read; for visual QA, convert the PPTX to images if the environment has LibreOffice and Poppler.

Template Workflow

• Use pptx_template_analyze when the user provides a .pptx template or wants to preserve existing layouts, charts, images, tables, or SmartArt.
• Build a template_fill_pptx_plan.v1 plan from the returned slide IDs and object IDs, then call pptx_template_fill.
• For SmartArt, use smartarts[*].smartart_id and smartarts[*].nodes[*].node_id in smartart_edits. This edits existing node text only; it does not create, delete, or relayout SmartArt nodes.
