Turn repository context into slides with Codex
A coding agent already understands the repository, decisions, and technical constraints behind a project. The TweakSlides skill lets Codex turn that context into a deck without flattening the result into an image or losing the source.
Install the plugin
Add the TweakSlides marketplace and plugin to Codex.
Define the evidence boundary
Tell Codex which files are authoritative, who the presentation is for, and which claims require citations.
Review and iterate
Open the proposal URL, inspect the deck, then ask for focused changes or edit the Markdown yourself.
Use the architecture decision records and current metrics fixture to build a 10-slide review. Separate verified facts from recommendations. Submit a TweakSlides proposal; do not modify source files.
A reviewable deck proposal with editable source, evidence-oriented slide structure, and no repository mutation.
Install
The plugin packages the TweakSlides workflow so Codex can produce DeckIR or Markdown and submit it as a browser-reviewed proposal.

From implementation detail to presentation narrative
Repository documents are usually organized for builders, not an audience. Ask Codex to identify the decision, group evidence, and remove implementation detail that does not support the story. Keep links or filenames beside claims that need verification.
Because the deck source remains text, later updates can be small. A changed metric or roadmap item does not require recreating every slide.
Useful deck types
The workflow fits architecture reviews, launch updates, conference talks, product pitches, incident retrospectives, and roadmap briefings. It is strongest when the repository contains the facts and the human supplies the audience and intended decision.
What it does not do yet
- Codex needs access to the source files you want summarized.
- The agent should not infer business facts that are absent from the repository.
- Editable PPTX export is not available yet.
Questions, answered plainly
Will Codex modify my repository to make the deck?
Not when you request a proposal-only workflow. The deck is submitted to TweakSlides for browser review.
Can Codex render a preview?
The TweakSlides agent surface supports deck validation and slide preview rendering in addition to proposal and edit operations.
Can I continue editing by hand?
Yes. Agent edits and manual Markdown edits update the same canonical deck source.
