Proceed. - **If you don't have write access** (typical open source): you need a fork. Check if the remote is already your fork. If not, tell the user: "You'll need to fork this repo first. Run `gh repo fork` (GitHub) or fork via the GitLab UI, then add your fork as a remote: `git remote add origin {your-fork-url}`. Push to your fork, not upstream." - After forking, ensure the branch will create a PR from `your-fork:branch` to `upstream:main`. `gh pr create` handles this automatically when the upstream remote is configured. ## Progress Visibility (MANDATORY) Contrib...
