# Git push
When the user asks to push (including phrases like “push”, “push to remote”, or “git push”):
1. Run `git status` (and if needed `git diff`) to check for unstaged/uncommitted changes.
2. If there are changes worth shipping, stage and **commit first**—never omit secrets such as `.env`, credentials files, or private keys. Follow the repo’s commit message conventions.
3. Then run `git push` to the tracked upstream.
If nothing is staged and the working tree is clean, pushing without a commit is fine.
