for one thing, you are forgetting that people are human. this is what that workflow would more realisticly look like:

    cd /yor/src/dir
    bash: cd: /yor/src/dir: No such file or directory

examines closely to look for typo cd /your/src/dir

    <edit stuff>

    git diff

    git comit -m "edited stuff"
    Did you mean this? git: 'comit' is not a git command. See 'git --help'.

Did you mean this? commit git commit -m "edited stuff"

I think this is enough to get the picture.
