65Use $slides with $imagegen to edit this slide deck in the following way:
66 - If present, add logo.png in the bottom right corner on every slide
67- On slides X, Y and Z, move the text to the left and use image generation to generate an illustration (style: abstract, digital art) on the right
68- Preserve text as text and simple charts as native PowerPoint charts where practical.
69 - Add these slides: [describe new slides here]
70- Use the existing branding on new slides and new text (colors, fonts, layout, etc.)
71- Render the updated deck to slide images, review the output, and fix layout issues before delivery.
72- Run overflow and font-substitution checks before delivery, especially if the deck is dense.
73- Save reusable prompts or generation notes when you create a batch of related images.
74 Output:
75 - A copy of the slide deck with the changes applied
76 - notes on which slides were generated, rewritten, or left unchanged

91## Introduction
92
93You can use Codex to manipulate PowerPoint decks in a systematic way, using the Slides skill to create and edit decks with PptxGenJS, and using image generation to generate visuals for the slides.
94
95Skills can be installed directly from the Codex app–see our [skills documentation](https://developers.openai.com/codex/skills) for more details.
96
97You can create new decks from scratch, describing what you want, but the ideal workflow is to start from an existing deck–already set up with your branding guidelines–and ask Codex to edit it.
98
99## Start from the source deck and references
100
101If a deck already exists, ask Codex to inspect it before making changes.
102
103The slides skill is opinionated here: match the source aspect ratio before you rebuild layout, and default to 16:9 only when the source material does not already define the deck size. If the references are screenshots or a PDF, ask Codex to render or inspect them first so it can compare slide geometry visually instead of guessing.
104
105## Keep the deck editable
106
107When building out new slides, ask Codex to keep the slides editable: when slides contain text, charts, or simple layout elements, those should stay PowerPoint-native when practical. Text should stay text. Simple bar, line, pie, and histogram visuals should stay native charts when possible. For diagrams or visuals that are too custom for native slide objects, Codex can generate or place SVG and image assets deliberately instead of rasterizing the whole slide.
108
109For example, if you want to build a complex timeline with illustrations, instead of generating a whole image, ask Codex to generate each illustration separately (using a set style prompt as reference), place them on the slide, then link them using native lines. The text and dates should be text objects as well, and not included in the illustrations.
110
111## Generate visuals intentionally
112
113Image generation is most useful when the slides need a cover image, a concept illustration, or a lightweight diagram that would otherwise take manual design work. Ask Codex to define the visual direction first, then reuse that direction consistently across the whole deck.
114
115When several slides need related visuals, have Codex save the prompts or generation notes it used. That makes the deck easier to extend later without starting over stylistically.
116
117## Keep slide logic explicit
118
119Deck automation works better when Codex treats each slide as its own decision. Some slides should preserve exact copy, some need a stronger headline and cleaner structure, and some should stay mostly untouched apart from asset cleanup or formatting fixes.
120
121The slides skill also ships with bundled layout helpers. Ask Codex to copy those helpers into the working directory and reuse them instead of reimplementing spacing, text-sizing, and image-placement logic on every deck.
122
123## Validation before delivery
124
125Decks are easy to get almost right and still ship with clipped text, substituted fonts, or layout drift that only shows up after export. The slides skill includes scripts to render decks to per-slide PNGs, build a quick montage for review, detect overflow beyond the slide canvas, and report missing or substituted fonts.
126
127Ask Codex to use those checks before it hands back the final deck, especially when slides are dense or margins are tight.
128
129## Example ideas
130
131Here are some ideas you could try with this use case:
132
133### New deck from scratch
134
135You can create new slide decks from scratch, describing what you want slide by slide and the overall vibe.
136If you have assets like logos or images, you can copy them in the same folder so that Codex can easily access them.
137
138Create a new slide deck with the following slides:
139- Slide 1: Title slide with the company logo (logo.png) and the title of the presentation
140- Slide 2: Agenda slide with the key points of the presentation
141- Slide 3: [TITLE] [TAGLINE] [DESCRIPTION]
142- ...
143- Slide N: Conclusion slide with the key takeaways
144- Slide N+1: Q&A slide with my picture (my-picture.png)
145
146### Deck template update
147
148You can update a deck template on a regular basis (weekly, monthly, quarterly, etc.) with new content.
149If you're doing this frequently, create a file like `guidelines.md` to define the content and structure of the deck and how it should be updated.
150
151Combine it with other skills to fetch information from your preferred data
152 sources.
153
154For example, if you need to give quarterly updates to your stakeholders, you can update the deck template with new numbers and insights.
155
156Update the deck template, pulling content from [integration 1] and [integration 2].
157Make sure to follow guidelines defined in guidelines.md.
158
159### Adjust existing deck
160
161If you built a deck but want to adjust it to fix spacing, misaligned text, or other layout issues, you can ask Codex to fix it.
162
163Adjust the deck to make sure the following layout rules are followed:
164- Spacing should be consistent when there are multiple items on the same slide displayed in a row or grid.
165- When there are multiple items on the same slide displayed in a row or grid, the items are aligned horizontally or vertically depending on the content.
166- All text boxes should be aligned left, except when they are below an illustration
167- All titles should use the font [font name] and size [size]
168- All captions should be in [color]
169- ....
