Export as PPTX (editable)

Export an HTML slide deck to a .pptx with native PowerPoint objects (editable text, shapes, images). One gen_pptx tool call does everything: capture, font handling, generation, download.

What you do

1. Know the deck. You probably wrote it. If not, read_file the HTML to find: the slide selector, how to navigate (function name? class toggle?), what fonts it uses, whether there's a scaling wrapper.
2. show_to_user the deck so it's in the user's preview.
3. Call gen_pptx with the inputs below.
4. Read the validation flags in the result and decide if you need to retry.

gen_pptx inputs

{
  "width": 1920, "height": 1080,   // CSS px — match the deck's slide size
  "slides": [                      // one entry per slide, in order
    { "showJs": "goToSlide(0)", "selector": ".slide.active" },
    { "showJs": "goToSlide(1)", "selector": ".slide.active" }
    // For decks where all slides are in DOM at once and you don't need to navigate:
    //   { "selector": ".slide:nth-child(1)" }, { "selector": ".slide:nth-child(2)" }
  ],
  "hideSelectors": [".nav", ".progress", "[data-omelette-chrome]", "[data-noncommentable]"],
  // If the deck wraps slides in a transform:scale() container, name it here.
  // gen_pptx clears the transform AND forces width/height onto this element.
  "resetTransformSelector": ".slide-container",
  // Font handling — pick ONE strategy based on the directive at the bottom.
  // Substitution happens BEFORE capture so layout reflows correctly.
  "googleFontImports": ["Poppins", "Lora"],
  "fontSwaps": [{ "from": "BrandSans", "to": "Poppins" }],
  // Or fontSwaps: [{from:"BrandSans", to:"Arial"}] for web-safe.
  // Or omit both to keep brand fonts as-is.
  "filename": "my-deck"
}

If — and only if — the user asked for Google Slides, also pass "offer_google_slides": true: the export dialog gains a 'Send to Google Slides' button, and the upload happens only if they click it.

slides[].showJs runs inside the iframe as a sync expression — don't await. If your deck's nav function is async, call it without await; the per-slide delay (default 600ms) covers the transition. Bump delay for decks with longer CSS transitions.
