Image PPT Maker

Help users create a set of PPT-style slide images with image-2. Use a strict review-gated workflow:

1. Confirm requirements.
2. Build a McKinsey-style master outline and page-by-page outline.
3. Expand the outline content.
4. Confirm the desired visual style for the images.
5. Write unified-style image-2 prompts.
6. Batch-generate 16:9 PPT images.
7. Review the generated images with the user and revise affected pages if needed.
8. Assemble the user-approved final images into a playable 16:9 HTML slideshow.
9. Write duration-aware, directly readable oral speaker notes based on the approved outline and final images.

Ask the user whether they want changes at each review gate. Do not assemble HTML or write final speaker notes until the user explicitly approves the generated images.

Required References

• Read workflow.md before starting any task.
• Read mckinsey-outline.md before drafting or revising outlines.
• Read image-2-prompts.md before writing prompts or generating images.
• Use generate-html-player.mjs only after the user approves final local images for a playable HTML output.

Core Rules

1. Use the user's language for questions and deliverables unless they specify another deck language.
2. If key information is missing, ask concise questions before outlining: topic, goal, audience, style, duration, slide count, information density, source material, constraints, and whether to reserve a small LOGO area in the upper-left or upper-right corner.
3. Summarize the confirmed brief and ask whether the user has changes before creating the outline.
4. Use McKinsey-style logic: answer first, issue-tree thinking, MECE where practical, one governing thought per slide, and a clear so what.
5. Every page in the outline must include logic notes. Do not create title-only or decorative pages.
6. After the outline is approved, expand each page with richer content, examples, implications, and visual emphasis. Do not output speaker notes yet.
7. Before writing image prompts, ask the user what visual style they prefer and recommend context-aware options such as training style with friendly editorial illustrations, executive report style with restrained illustration accents, illustration-led storytelling with recurring characters and scenes, graphic/chart-heavy, product demo style, or other suitable options.
8. Generate one image per slide, 16:9, with image-2. Do not create final slide images with SVG, HTML, screenshots, local drawing, PowerPoint export, or montage workflows.
9. Treat image generation as a long-running operation. Do not interpret a quiet period, a partial preview, or a tool call with no immediate new image as failure. Keep the generation task alive, wait for its final completion signal, inspect the output directory for newly completed files, and report progress without triggering a duplicate generation. Retry only after an explicit tool failure, confirmed timeout, or confirmed missing/corrupt output after completion.
10. After image generation, present the final image paths or previews and ask the user whether any page needs adjustment. Do not assemble HTML or write final speaker notes until the user explicitly approves the images.
11. After the user approves the images, automatically generate a playable 16:9 HTML slideshow from the final local images.
12. After HTML assembly, write final per-slide speaker notes based on the approved outline and final images. Allocate page-level speaking time to match the confirmed duration, and write a complete, directly readable oral script for each page.
13. This skill does not assemble PPTX files. Stop at generated images, HTML slideshow, prompt records, final speaker notes, and revision notes.
14. Preserve approved work during revisions. Only regenerate the affected downstream artifacts.

Workflow Gates

Do not skip these review points:

• After requirement parsing: ask whether the brief and assumptions need changes.
• After the master outline and page-by-page outline: ask whether the storyline, page count, or logic needs changes.
• After the expanded outline content: ask whether the content depth, examples, or emphasis needs changes.
• Before writing image-2 prompts: ask which visual style the user prefers, offering context-aware recommendations that include concrete illustration directions when illustration is suitable.

• After image-2 prompts: ask whether the style, visible text, or page prompts need changes.
• After image generation: present the completed images and ask whether any page needs changes; wait for explicit approval before HTML assembly and final speaker notes.
• After HTML assembly and final speaker notes: ask whether any HTML output or speaker note should be adjusted.

If the user requests changes:

• Requirement changes invalidate outline, prompts, and images.
• Outline changes invalidate affected expanded content, prompts, images, HTML, and final speaker notes.
• Visual-style changes invalidate prompts, images, HTML, and final speaker notes.
• Final speaker-note changes do not invalidate prompts, images, or HTML unless the visible slide content or logic changes.
• Prompt or style changes invalidate the affected images.
• Image issues require regenerating only the affected pages when possible; re-run the image review gate after every image revision.
• HTML output must be regenerated if final image filenames, image count, title, or image folder changes.

Deliverables

When complete, provide:

• confirmed brief;
• master outline and page-by-page outline;
• expanded outline content;
• image-2 prompt set with the shared style lock;
• generated image paths or previews;
• playable 16:9 HTML slideshow path;
• final oral speaker notes based on the outline and generated images;
• concise notes on pages that may need regeneration.

這個 Skill 質量不錯，流程設計很規範，從確定需求到出最終成品每一步都有確認環節。最大的優點是邏輯框架嚴謹，用麥肯錫方法論來組織內容，確保每一頁都言之有物。使用者可以在每個關鍵節點稽核和修改，不用擔心產出跑偏。圖片生成和 HTML 播放器的功能實現也比較完整。不足之處是缺少使用示例和更詳細的講稿寫作指導，對新使用者來說可能需要花時間理解各個階段的產出要求。總體來說這是一套專業度較高的 PPT 圖片生成方案。
