refresh-fork

Refresh fork to match upstream, preparing for new contributions.

Process

1. Check upstream exists

   git remote get-url upstream
   

   If fails: stop with error "No upstream remote configured. This doesn't look like a fork."

2. Determine default branch

   git remote show upstream | grep 'HEAD branch' | awk '{print $NF}'
   

   Fallback: try main, then master

3. Discard local state

   git checkout <default-branch>
   git reset --hard
   git clean --force -d
   

4. Sync with upstream

   git fetch upstream
   git reset --hard upstream/<default-branch>
   

5. Push to origin

   git push origin <default-branch> --force
   

6. Confirm

   Report: synced to which commit (short sha + message), now on <default-branch>
