git branch --show-current # confirm we're on a feature branch, not main
git log --oneline main..HEAD

The current branch is main. Ask the user to create a feature branch first.
The branch has no commits ahead of main. Nothing to open a PR for.
There are uncommitted changes the user hasn't asked to commit.
