Gonna have to try that out. I think it would have told interesting stories on some past repos.
I wish ''co-authored by AI' was easy to flag in vcs.

This is going into my bashrc as a mini cli. I'm pretty sure I'm going to want to run this every time I change jobs.
This would have no effect in my team where everyone does whatever they want in git lol
They're bash/shell- and bin-dependent commands rather than Git commands. I use Nushell.
Transformed to Nushell commands:
- The 20 most-changed files in the last year:
git log --format=format: --name-only --since="1 year ago" | lines | str trim | where (is-not-empty) | uniq --count | sort-by count --reverse | take 20 - Who Built This:
git shortlog -sn --no-merges
git shortlog -sn --no-merges --since="6 months ago" - Where Do Bugs Cluster:
git log -i -E --grep="fix|bug|broken" --name-only --format='' | lines | str trim | where (is-not-empty) | uniq --count | sort-by count --reverse | take 20 - Is This Project Accelerating or Dying:
git log --format='%ad' --date=format:'%Y-%m' | lines | str trim | where (is-not-empty) | uniq --count - How Often Is the Team Firefighting:
git log --oneline --since="1 year ago" | find --ignore-case --regex 'revert|hotfix|emergency|rollback'
/edit: Looks like the lines have whitespace or sth. Replaced lines --skip-empty with lines | str trim | where (is-not-empty).
