Hi Product Hunt! When you run several coding agents on one repository at once, one session can silently overwrite another's edit to the same file. Nothing fails, the tests pass, the work is just gone. So we built a grader for the evidence you already have: your git log. Run the one-line command it shows, paste the output, and it lists each file two sessions touched within 60 minutes, with both commits and the gap between them. What it reads: commit hashes, author names, times, branch names and file paths. Nothing leaves the page after you paste; the only analytics is the page view. It's free and stays free. It comes from memento, a working memory for people and agents; the shared version for teams is on pre-order on our site, if the grader shows you a problem. What's the worst file in your repo?

Did two of your coding agents edit the same file in an hour?
