01 What It Does

Codex PPT: Image-Based Slide Decks

A gated image-generation and PowerPoint-assembly workflow with sample approval, per-slide job records, inspection, and speaker-note alignment.

Source-based workflowNot an execution benchmark

The Working Approach

Codex PPT organizes presentation production around full-slide images. Each 16:9 slide is generated as one visual, then assembled into a PowerPoint file. That makes it a specific choice for a visually unified deck, not a general replacement for authoring editable text boxes, charts, and shapes.

The source separates outline approval, visual direction, backend selection, and sample approval before full-deck production. It also records slide jobs and results so that the final assembly can be checked against the approved plan. A polished sample is the reference for the remaining slides, not permission to silently change the generation method.

Expected Deliverables

  • A PPTX assembled from complete slide images
  • An approved outline and matching speaker notes
  • Recorded slide jobs, selected image results, and QA status
See the Example Brief

From Brief to Review

  1. 01
    Define the Narrative

    Supply the audience, purpose, source document, and essential figures. Approve the slide roles before spending effort on image generation.

  2. 02
    Approve One Slide

    Choose a visual direction and image backend, then review a single representative slide. Preserve its generation method as the full-deck baseline.

  3. 03
    Produce and Review

    After sample approval, dispatch each remaining slide job to a slide subagent whenever the runtime supports them. Record results through the bundled scripts, inspect text and required assets, and repair failed slides before assembly.

  4. 04
    Assemble the Deck

    Use the supplied assembly workflow only after each expected slide has an accepted or recorded result. Align speaker-note headings with the final slide order.

02 When to Use It

When to Use It

Python 3, an available image-generation backend, and the repository's assembly and state-recording scripts. Referenced workflow documents are required for actual execution.

A Good Fit

  • Visual PresentationsUseful for a report or article that needs a consistent visual narrative and can be delivered as full-slide artwork.
  • Controlled Batch ProductionThe sample gate and job records make sense when a deck has enough slides for style drift or missing outputs to become a concern.

Limits to Check

  • Not Object-EditableText, charts, and illustrations remain inside slide images. Choose another approach if the recipient must edit those items independently in PowerPoint.
  • Generation PrerequisitesThe workflow requires an available image backend and Python assembly. Slide workers are mandatory after sample approval when the runtime supports subagents. If a required worker, backend, or image input is unavailable, the source requires a blocker report rather than an improvised replacement.

Bring These Inputs

  • Source MaterialProvide the article, paper, report, or notes and identify facts that must survive condensation.
  • Required VisualsMap supplied figures, screenshots, and logos to the slides where they must appear.
  • Approval ConstraintsState page count, audience, brand guidance, permitted backend, and who will approve the sample.

03 Decisions That Matter

Decisions That Matter

  1. One Visual Contract

    A fixed backend and accepted sample give the remaining slide jobs a concrete visual reference.

  2. Assembly Is a Separate Gate

    Generation records distinguish missing slides from finished images before a PPTX is called complete.

Review the Setup

Obtain the complete codex-ppt skill directory from the source repository, including docs, prompts, and scripts; the entry file is not a standalone deck generator.

Python 3, an available image-generation backend, and the repository's assembly and state-recording scripts. Referenced workflow documents are required for actual execution.

Start With One Deliverable

Adapt the scope, source material and constraints in this brief before running the skill.

Example Brief
Use Codex PPT to plan an eight-slide presentation from the attached research report for product leaders. Preserve the two supplied figures. I accept image-based slides, but need speaker notes. Start with an outline for approval; then propose style and backend choices and generate only one sample before the rest of the deck.

Inspect the Result

Check the actual output against these observable criteria.

  • Every planned slide has a recorded final image.
  • Required figures remain legible and the deck uses one visual identity.
  • The PPTX opens and speaker notes match the final slide order.

06 Questions Before You Start

Questions Before You Start

Can I edit individual text boxes afterward?

Not with this workflow's default output. A slide is a complete image inside the PPTX; separately editable objects are explicitly outside its intended use.

Does it require an API key?

The source prefers a built-in image tool. Its CLI fallback may use an API key and endpoint configuration; confirm that path before generation.

Can I skip straight to the full deck?

The documented process uses outline, style, backend, and sample approvals first. Those gates are part of how it controls visual consistency.
