I think it can be more compact, but for now, I'll put the prompt here because I personally found it exciting. Feel free to skill-ify it or customize it as needed. Codex and Copilot Cowork natively have an image generation tool powered by GPT-Image-2, so using it in conjunction with PPTX creation allows for great slides. Since it's almost entirely image generation, if you want to convert it into editable objects, use the method I posted in a reply the other day. --- # Instructions ## 1. Slide Creation Method Please turn the content into slides. This presentation should be created using the **Image-Native Infographic Deck** method. Each slide should be a **standalone readable slide** that allows the content to be understood even without verbal explanation from the presenter. Do not rely solely on diagrams or short labels; include a **careful narrative explanation in text** to accurately convey the background, key points, relationships, meaning, and conclusions to the reader. --- ## 2. Structure of Each Slide Each slide should consist of only the following three elements: 1. **An editable 1-line title in PowerPoint** 2. **An editable, Semibold narrative lead sentence in PowerPoint** 3. **A 16:9 image-native infographic integrating body text, diagrams, labels, icons, and supplementary explanations** The title and lead sentence should not be generated within the image; they should be placed as editable text in PowerPoint, in the same position on all slides. The lead sentence should not be a mere summary, catchphrase, or auxiliary short sentence. It should be a **narrative and careful explanatory sentence that allows the reader to fully understand the content, argument, meaning, and conclusion intended for that slide, even if only the lead sentence is read.** --- ## 3. Independence as a Readable Document and Narrative Each slide should be understandable by reading only that page, without assuming prior or subsequent slides or supplementary explanations from the presenter. Avoid compositions that merely list words, noun phrases, or short bullet points; include a **narrative explanation that flows naturally as a sentence.** Even for cards and labels within diagrams, appropriately place sentences that convey the meaning and context of the information, not just classify it. However, do not indiscriminately cram in redundant sentences. Visually organize headings, body text, key points, supplementary information, and conclusions so that the reading order is naturally apparent. --- ## 4. Writing Style All text on the slides, including titles, lead sentences, body text within images, headings, and supplementary explanations, should use a **concise and refined explanatory tone that does not use "desu/masu" or "da/dearu" forms.** The sentence endings should naturally vary according to the content, using the following forms: * Nominal endings (taigen-dome) * Attributive or terminal forms of verbs * Explanatory noun phrases such as "structure that ~," "positioning as ~," "necessity of ~," "potential to lead to ~" * Connecting expressions that show the relationship with subsequent information, such as "due to ~," "through ~," "premised on ~" * Predicate expressions that concisely indicate conclusions or meanings Do not use sentence endings such as "desu," "masu," "deshita," "mashita," "deshou," "da," "dearu," or "to naru no dearu." However, do not create sentences that consist only of words, noun phrases, or short fragments by continuously using nominal endings. Maintain a natural flow as a sentence so that the relationship between subject and predicate, reason and conclusion, premise and meaning is conveyed to the reader. Do not mechanically repeat the same sentence ending form. Appropriately combine nominal endings, verbal endings, and expressions indicating cause and effect or change to avoid monotony. The overall writing style should be objective and calm, suitable for reports, explanatory articles, and research materials. Do not use conversational expressions, direct address, exclamations, or overly assertive expressions. --- ## 5. Infographic Expression Policy Do not separate body text and illustrations into left/right or top/bottom sections. Integrate the content of the body text itself into visual expressions such as: * Diagrams * Cards * Arrows * Comparisons * Cycles * Layers * Grouping * Icons * Pill-shaped labels Instead of constructing diagrams by combining PowerPoint shapes, use an image generation tool to create a complete infographic image, including the body text. Diagrams and icons should not be decorative substitutes for text. They should be used in conjunction with narrative explanations to make the structure, relationships, flow, comparisons, and causal relationships of information easier to understand. --- ## 6. Slide Size * Aspect ratio: 16:9 * Width: 13.333 inches * Height: 7.5 inches * Infographic image: Placed across the entire slide --- ## 7. Title Specifications | Item | Specification | | ------------- | ------------------ | | x | 0.46 inches | | y | 0.10 inches | | w | 12.42 inches | | h | 0.48 inches | | Font | Yu Gothic UI | | Font Size | 28.2pt | | If long | Can be reduced to 27.4pt | | Weight | Bold | | Text Color | `#14243A` | | Character Spacing | Standard to minus 0.4pt | | Line Count | 1 line | | Margin | 0 | The title should be an expression that specifically conveys the theme or argument of that slide. It should not be an abstract chapter title or a general noun alone. As much as possible, it should be a title that conveys the specific point of that slide. The title must fit on one line. If it does not fit on one line, first revise the text, and if necessary, adjust the character spacing down to minus 0.4pt. Only if it still does not fit, reduce the font size to 27.4pt. When narrowing character spacing, ensure it does not impair the readability of Japanese text. --- ## 8. Lead Sentence Specifications | Item | Specification | | ------------- | ------------------ | | x | 0.48 inches | | y | 0.60 inches | | w | 12.36 inches | | h | 0.68 inches | | Font | Yu Gothic UI | | Font Size | 15.8pt | | Weight | Semibold | | Emphasized parts | Bold only if necessary | | Text Color | `#40536A` | | Line Count | Principally 2 lines, maximum 2 lines | | Line Spacing | 1.05 to 1.10 | | Margin | 0 | The lead sentence should be a **sentence that, when read alone, allows for a complete understanding of the content intended for that slide.** It should not be a mere subtitle, short summary, impressive copy, or nominal ending. It should integrate the following elements into a single, natural sentence as much as possible: * The subject of the slide * The central argument or conclusion * The reasons or structure leading to that conclusion * The meaning or implications the reader should understand * However, do not make unfounded assertions or speculations. The lead sentence should be a narrative and careful explanation, and should not be an information-deficient sentence that requires reading the body text to understand the argument. Aim for approximately 70-105 Japanese characters, and fit it into principally 2 lines, maximum 2 lines. Allow line breaks to occur naturally based on the width of the PowerPoint text box. Do not assign different roles to the first and second lines, or unnaturally alter the text to equalize line lengths. The entire lead sentence should be Semibold. For central conclusions or important keywords, 1-2 places can be Bold if necessary. However, do not make the entire lead sentence Bold. Automatic font size reduction to fit is prohibited. If it exceeds 2 lines, do not reduce the font size; instead, revise the text by removing redundant content or verbose expressions. After actual rendering from PowerPoint, confirm that the font size remains 15.8pt. --- ## 9. Safe Area at Top of Image When generating images, ensure the top **18% of the image is a completely white safe area.** Do not place any of the following elements in this area: * Text * Cards * Lines * Icons * Background color changes * Important shapes * Decorative elements The main elements of the body text and infographic must start below the 18% boundary at the top. Ensure a minimum of 0.05 inches of space between the bottom edge of the editable lead sentence and the starting position of the body text and infographic within the image. --- ## 10. Design Policy The infographic should be bright, sophisticated, and flat 2D. ### Color Palette Based on calm neutral colors, with a color scheme that feels warm and intelligent. * Background: * Ivory white * Pale sand beige * Very light greige * Body text: * Charcoal navy * Dark slate * Cards: * Warm white * High-contrast composition with clear distinction from the background * Accent colors: * Deep teal: key concepts, conclusions * Sage green: supplementary information, stability, continuity * Terracotta: challenges, changes, precautions * Mustard yellow: important points, emphasis * Dusty blue: processes, connections, reference information * Plum: advanced concepts, differentiating elements Accent colors should not be evenly distributed as decoration. They should be used consistently according to the meaning, classification, and importance of the information. Overall saturation should be subdued, ensuring sufficient contrast between cards, arrows, pills, icons, and headings. ### Style * Uniform line width * Subtle rounded corners * Subtle shadows * Clear information hierarchy * Clear reading order * High-density yet organized composition * Visual elements used to explain information structure and causal relationships * Layout that allows narrative text to be read smoothly * Text design that distinguishes the roles of headings, body text, key points, supplementary information, and conclusions Visuals should not be for decorative purposes; they should be used to explain the structure, comparisons, relationships, flow, and causal relationships of information. --- ## 11. Information Density The amount of information can be high, and the slide can be busy. Instead of increasing white space for a minimalist look, organize high-density information using the following elements: * Cards * Headings * Pills * Colors * Icons * Arrows * Grouping * Hierarchical structures * Comparative expressions * Process expressions * Careful narrative text expressions Instead of omitting explanations to reduce information, divide the text into appropriate units and use cards, headings, emphasis, connecting lines, etc., to organize it into an information structure that is easy to understand as a readable document. Instead of conveying information solely through short keywords, include the necessary context, reasons, meanings, and conclusions in the text. --- ## 12. Prohibitions Do not use the following expressions: * Realistic depictions * Stock photos * 3D effects * Bevels * Glass effects * Heavy shadows * Cheap-looking PowerPoint shapes * Layouts that separate body text and illustrations * Too small text * Low contrast * Page numbers * Watermarks * Fake logos * Duplication of titles within the image * Duplication of lead sentences within the image * Compositions that rely solely on words or short labels for explanation * Omission of information that cannot be understood without verbal explanation from the presenter * Lists of bullet points lacking context or conclusions * Abstract catchphrases that do not explain content --- ## 13. Accuracy of In-Image Text All Japanese text displayed within the image must be specified in the image generation prompt as **an exact match string.** After generation, check the following at actual size: * Typos * Missing characters * Garbled text * Product names * English spelling * Numerical values * Labels * Connection relationships of arrows * Logical relationships within diagrams * Contradictions between information * Inconsistencies in causal relationships * Correspondence between subject and predicate in sentences * Naturalness of narrative text * Lack of necessary context for explanation * Consistency of claims between lead sentence and body text If there are errors, correct them through image editing, rather than by overlaying and hiding with PowerPoint text. --- ## 14. Information Sources and Expressive Constraints For product information and time-dependent information, verify using official primary sources. Avoid the following expressions: * Excessive sales language * Assertions that could be interpreted as product guarantees * Unfounded claims of superiority * Decorative text that does not add content * Speculation that cannot be confirmed from official information * Conclusions without presented evidence or reasons * Explanations that omit premises necessary for the reader's understanding Even when adding narrative explanations, limit them to facts verifiable from official information and explanations directly derivable from them. --- ## 15. Rendering and Quality Check After completion, always perform an actual rendering from PowerPoint to PDF. Check using the following two display methods: 1. Thumbnail view of all slides 2. Actual size view of each page Perform the render → fix → re-render process at least once. The items to check include: * Position of title and lead sentence * Font * Font size * Weight * Character spacing of title * Line breaks * Image placement * 18% safe area at the top * Readability of text * Accuracy of in-image text * Information hierarchy * Design consistency across slides * Layout distortion during PDF conversion * Whether each slide functions as a standalone readable document * Whether content can be understood without presenter's explanation * Whether the slide's argument and conclusion are conveyed by the lead sentence alone * Whether the body text includes background, relationships, reasons, meaning, and conclusions * Whether narrative text flows naturally without unnatural breaks * Whether diagrams and text show the same logical structure * Whether the title fits on one line * Whether the title's character spacing is not less than minus 0.4pt * Whether the lead sentence is not unnecessarily shortened to one line * Whether the lead sentence fits principally 2 lines, maximum 2 lines * Whether the lead sentence contains approximately 70-105 characters of information * Whether the actual font size of the lead sentence is maintained at 15.8pt * Whether the base weight of the lead sentence is Semibold * Whether the entire lead sentence is not Bold * Whether parts other than key points in the lead sentence are not excessively emphasized * Whether the lead sentence has natural automatic line breaks * Whether the text is not unnaturally altered to equalize line lengths * Whether there is a minimum of 0.05 inches of space between the lead sentence and the image body text --- ## 16. Deliverables Finally, deliver the following three files: * Editable PowerPoint file (PPTX) * PDF for review * Markdown file summarizing the image generation prompts used to create each slide image
