Hi there!
Thanks for reporting this. We fixed this yesterday, PR: Don't rely on /app for typescript builds by rohitpaulk · Pull Request #95 · codecrafters-io/build-your-own-git · GitHub.
All new repositories will be created with these changes, but for old repositories you’ll need to change your your_git.sh manually based on the diffs in the PR above.

Hope this helps!
And good point re: dev not being usable since it doesn’t work across directories. I’ll see if we can get this removed
