Why Codex-only?
Most "AI PPT" skills wrap Gemini / OpenAI Image / Nano Banana API calls — every slide costs money. **Codex has built-in `image_gen`**: it's already paid for via your Codex subscription. The whole point of this skill is to use that built-in capability instead of burning a second image API.
If you run this skill in Claude Code or Cursor, the built-in `image_gen` doesn't exist there, and the skill won't work as intended. Use [`huashu-design`](https://github.com/alchaincyf/huashu-design) (HTML-native) or [`huashu-wechat-image`](https://github.com/alchaincyf/huashu-skills) (Gemini-backed) for those runtimes.
What it does
Four delivery paths, all powered by Codex's `image_gen`:
| Path | Output | Use when |
|---|---|---|
| Path 1 · AI Image PPT (default) | PPTX + HTML deck, each slide is a full image | Presentations, course material, pitch decks |
| Path 2 · HTML Image Deck | Full-screen web deck (←/→ keys) | Quick preview, web-published decks |
| Path 3 · Editable HTML → PPTX | Editable text PPTX | Only when user explicitly says "I need editable text" |
| Path 4 · Single Cover Image | WeChat / Bilibili / YouTube / Xiaohongshu cover PNG | Article hero images, video thumbnails, marketing posters |
