# Create GitHub Pull Request Create or update a GitHub pull request for the current branch against `main`. ## Context Gathering Gather context before drafting: - `git fetch origin main` — refresh `origin/main` so the ranges below are accurate. - `git config --get remote.origin.url` — origin URL. - `git branch --show-current` — current branch. - `git status --short` — working tree state. - `gh pr view --json number,state,url` — detect an existing PR for this branch (exits non-zero / empty when none, keying the create-vs-edit choice). - `git log --reverse --oneline origin/main..HEAD` — commits since `main`. - `git diff --stat --find-renames origin/main...HEAD` — diff stats. - `git diff --name-only --find-renames origin/main...HEAD` — changed files. ## Workflow 1. If the current branch is `main`, stop and say a PR must come from a feature branch. 1. Inspect changed files as needed so the PR matches the actual work, not just the commit subjects. 1. Write a clear PR title in imperative mood, **under 72 characters**. 1. Write a Markdown body with these sections: ```markdown ## What ## Why ## How ## Test plan ``` 1. Push the current branch to `origin` with upstream if needed (`git push -u origin <branch>`). 1. If a PR already exists for this branch, update it: ```bash gh pr edit --base main --title "<title>" --body-file <tmpfile> ``` 1. Otherwise create it: ```bash gh pr create --base main --title "<title>" --body-file <tmpfile> ``` ...
