Edit your slide deck by leaving comments for an agent
A consulting teacher built Decks so Claude Code or Codex edits slides from his comments and replies on each slide; he says it replaced PowerPoint as his daily tool.

What they did
A former consultant who teaches deck-making built a local slide tool. Each deck is a single web page file. He writes comments under slides and pastes a prompt into Claude Code or Codex. The agent applies changes using his rules, like full-sentence titles and one idea per slide. It replies under each slide and checks its own work.
How it went
The author says this is now how he makes all his slides. Each round ends with screenshots, an audit, a numbered PDF and a saved version.
Worth knowing
Everything stays on your computer, but the agent still sends what it reads to its model provider. He has only tried Opus 5.5 and Sol 6.1.
Try it yourself with Claude Code
Open my slide deck at [deck file path]. Read the comments I left under each slide. For each one, make the change, or explain why you did not. Write a short reply under that slide. Follow these rules: titles are full sentences that state the point, one idea per slide, and charts that prove the title. Then screenshot the changed slides and check that the titles alone tell the story. Show me a summary before saving a new version.Swap the highlighted [parts] for your own details.
