Context
- Current branch: !
git branch --show-current
- Default branch candidates: !
git branch -r | grep -E 'origin/(main|master)'
- 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
- Detect the base branch by running:
git rev-parse --verify origin/main >/dev/null 2>&1 && echo main || echo master. Use this as <base>.
- If the current branch is the base branch, stop and tell the user to switch to a feature branch first. Do nothing else.
- Run
git log <base>..HEAD --oneline. If there are no commits ahead of the base branch, stop and tell the user to commit changes first. Do nothing else.
- Never run
git add or git commit. Only manage the PR.
Analysis
- Run
git diff <base>...HEAD to get the full diff of all changes on this branch.
- Run
git log <base>..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When updating, keep the existing title unless it is generic (e.g. "Update"), outdated, or does not follow Conventional Commits.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
First, check if the repository has a PR template. Look for these files in order:
pull_request_template.md in the repo root.github/pull_request_template.md.github/PULL_REQUEST_TEMPLATE/*.md
If multiple templates exist in .github/PULL_REQUEST_TEMPLATE/:
- Read all template files in that directory
- Analyze the current changes (types of files modified, nature of changes)
- Select the template whose filename and content best match the changes (e.g.,
bugfix.md for bug fixes, feature.md for new features, docs.md for documentation changes)
If a template is found:
- Use the template's content as the PR body
- Replace any placeholder variables (e.g.,
{{description}}, {{summary}}) with actual content derived from the changes
- If the template includes a checklist, only check items that are truly complete and verified. Leave items unchecked when the related work is not done, not validated yet, or failed.
- If you can reasonably perform a check needed to validate a checklist item (for example by reading the diff, inspecting files, or running an available verification command), do it before deciding whether the item should be checked.
If no template is found, use this default 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 "$(cat <<'EOF'
<body>
EOF
)"
Update flow:
- Update the PR:
gh pr edit --title "<title>" --body "$(cat <<'EOF'
<body>
EOF
)"
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.
- If the PR body includes a checklist from a template, never auto-check every item. Each checked item must match work that is actually done and confirmed.
- When a checklist item can be validated with available evidence or commands, verify it instead of guessing.
- Do not send any text besides the tool calls.
