## Description

Native text boxes only, python-pptx footguns encoded, self-verify against the original — five for five in my tests.

## Summary

One Prompt That Turns PDF Slides Into Editable PPTX is part of Tony Lee's ongoing coverage of AI agents, developer tools, startup strategy, and AI industry shifts.

## Outline

- No subheadings in source markdown

## Content

Sometimes you inherit a PDF deck and only need to change a few lines. I folded my personal slide-harness rules into one prompt that rebuilds **editable** PPTX via python-pptx for ChatGPT and Claude.

1. **Native elements only** — TextBoxes and real Shapes; ban image-of-text, SmartArt hacks, random SVG dumps. Editability is the point.
2. **Encode python-pptx traps** — proper dash styles, CJK font slots (ea/eastAsia/latin), right padding, exact HEX from source.
3. **Self-verify loop** — render beside original up to three passes; fix only visible errors so pixel OCD does not wreck layout. Dashed lines may look broken in PNG previews but fine in PowerPoint — teach the model that.

Five tests, five usable outputs. Not pixel-identical art — editable working files.
