This is a user script that adds a button on any GitHub Actions run page (summary or job) to jump directly to the newest run on the same workflow and branch.
You push a commit, which triggers a new CI run, but you are still viewing an old run or job in GitHub Actions. Switching to the newly triggered run or job can be cumbersome. This script automatically checks for a newer run on the same workflow and branch, then shows a button to jump there. If you are on a specific job page, it even links you to the equivalent job in the newer run. This way, you avoid digging through lists of runs or re-navigating from scratch.
