Context
- Current branch: !
git branch --show-current - Commits on this branch (since main): !
git log --oneline main..HEAD - PR for this branch: !
gh pr view --json number,title,url 2>/dev/null || echo "NO_PR"
Your task
Create or update a pull request for the current branch.
Pre-flight checks
- If the current branch is
main, stop and tell the user to switch to a branch first. Do nothing else. - If there are no commits ahead of main, stop and tell the user to commit changes first. Do nothing else.
- Never run
git addorgit commit. Only manage the PR.
Analysis
- Run
git diff main...HEADto get the full diff of all changes on this branch. - Run
git log main..HEAD --format="%h %s"to get all commit messages. - Identify the main topic, group specific changes logically.
Decide: create or update
- If the PR context above shows
NO_PR→ create a new PR. - If a PR is found for the current branch → update that PR.
PR title
Follow Conventional Commits format: <type>: <description>.
Types: feat, fix, docs, refactor, test, chore, build, perf, ci. Append ! for breaking changes.
When updating, keep the existing title unless it is generic (e.g. "Update"), outdated, or does not follow Conventional Commits.
PR body format
## Summary
<1-2 sentence high-level description of what this PR does and why>
## Changes
<bulleted list of all meaningful changes, grouped logically>
## Test plan
<bulleted checklist of how to verify these changes>
Execution
Create flow:
- Push the branch to origin:
git push -u origin <branch>. - Create the PR:
gh pr create --title "<title>" --body "<body>".
Update flow:
- Update the PR:
gh pr edit --title "<title>" --body "<body>".
Rules
- Write the summary in plain English, focusing on the why and the what.
- List changes as concise bullet points. Group related items under sub-headers if the PR touches multiple areas.
- The test plan should contain actionable verification steps relevant to the changes. If a check was already run and passed, mark it as done.
- Use a HEREDOC to pass the body to
gh pr createorgh pr edit. - Do not send any text besides the tool calls.
