A publishing change is easy to review badly. A reformatted template turns every paragraph into a diff, the one deleted sentence is buried in the noise, and a link that quietly started pointing somewhere else looks identical in a rendered preview.
This walkthrough uses the tool's public README and checked-in example files. Run the command from a repository checkout with Node.js 22+.
Run the checked-in example
mkdir -p build && node bin/publication-diff-bundler.mjs --before examples/snapshot-before --after examples/snapshot-after-clean --bundle build/review-bundle.json
