Slightly related, I get a lot of value out of a bash prompt which tells me:

- if my git repo is dirty (uncommitted changes)

- which branch it is on

- if (and how many) changes I have stashed

It's not originally my work but I find it massively useful, since it avoids the "committed but not pushed" failure mode, the "on wrong branch" failure more and the "stashed and forgotten about" failure mode.

I know that regularly running git status would work, but this is a useful visual reminder for me.
