Create Pull Request

This skill guides you through creating a well-structured GitHub pull request that follows project conventions and best practices.

Prerequisites Check

Before proceeding, verify the following:

1. Check if gh CLI is installed

gh --version

If not installed, inform the user:

The GitHub CLI (gh) is required but not installed. Please install it:

• macOS: brew install gh
• Other: https://cli.github.com/

2. Check if authenticated with GitHub

gh auth status

If not authenticated, guide the user to run gh auth login.

3. Verify clean working directory

git status

If there are uncommitted changes, ask the user whether to:

• Commit them as part of this PR
• Stash them temporarily
• Discard them (with caution)

Gather Context

1. Identify the current branch

git branch --show-current

Ensure you're not on main or master. If so, ask the user to create or switch to a feature branch.

2. Find the base branch

git remote show origin | grep "HEAD branch"

This is typically main or master.

3. Analyze recent commits relevant to this PR

git log origin/main..HEAD --oneline --no-decorate

Review these commits to understand:

• What changes are being introduced
• The scope of the PR (single feature/fix or multiple changes)
• Whether commits should be squashed or reorganized

4. Review the diff

git diff origin/main..HEAD --stat

This shows which files changed and helps identify the type of change.

Information Gathering

Before creating the PR, you need the following information. Check if it can be inferred from:

• Commit messages
• Branch name (e.g., fix/issue-123, feature/new-login)
• Changed files and their content

If any critical information is missing, use ask_followup_question to ask the user:

Required Information

1. Related Issue Number: Look for patterns like #123, fixes #123, or closes #123 in commit messages
2. Description: What problem does this solve? Why were these changes made?
3. Type of Change: Bug fix, new feature, breaking change, refactor, cosmetic, documentation, or workflow
4. Test Procedure: How was this tested? What could break?

Example clarifying question

If the issue number is not found:

I couldn't find a related issue number in the commit messages or branch name. What GitHub issue does this PR address? (Enter the issue number, e.g., "123" or "N/A" for small fixes)

Git Best Practices

Before creating the PR, consider these best practices:

Commit Hygiene

1. Atomic commits: Each commit should represent a single logical change
2. Clear commit messages: Follow conventional commit format when possible
3. No merge commits: Prefer rebasing over merging to keep history clean

Branch Management

1. Rebase on latest main (if needed):

   git fetch origin
   git rebase origin/main
   

2. Squash if appropriate: If there are many small "WIP" commits, consider interactive rebase:

   git rebase -i origin/main
   

   Only suggest this if commits appear messy and the user is comfortable with rebasing.

Push Changes

Ensure all commits are pushed:

git push origin HEAD

If the branch was rebased, you may need:

git push origin HEAD --force-with-lease

Create the Pull Request

IMPORTANT: Read and use the PR template at .github/pull_request_template.md. The PR body format must strictly match the template structure. Do not deviate from the template format.

When filling out the template:

• Replace #XXXX with the actual issue number, or keep as #XXXX if no issue exists (for small fixes)
• Fill in all sections with relevant information gathered from commits and context
• Mark the appropriate "Type of Change" checkbox(es)
• Complete the "Pre-flight Checklist" items that apply

Create PR with gh CLI

gh pr create --title "PR_TITLE" --body "PR_BODY" --base main

Alternatively, create as draft if the user wants review before marking ready:

gh pr create --title "PR_TITLE" --body "PR_BODY" --base main --draft

Post-Creation

After creating the PR:

1. Display the PR URL so the user can review it
2. Remind about CI checks: Tests and linting will run automatically
3. Suggest next steps:
   • Add reviewers if needed: gh pr edit --add-reviewer USERNAME
   • Add labels if needed: gh pr edit --add-label "bug"

Error Handling

Common Issues

1. No commits ahead of main: The branch has no changes to submit

   • Ask if the user meant to work on a different branch

2. Branch not pushed: Remote doesn't have the branch

   • Push the branch first: git push -u origin HEAD

3. PR already exists: A PR for this branch already exists

   • Show the existing PR: gh pr view
   • Ask if they want to update it instead

4. Merge conflicts: Branch conflicts with base

   • Guide user through resolving conflicts or rebasing

Summary Checklist

Before finalizing, ensure:

• gh CLI is installed and authenticated
• Working directory is clean
• All commits are pushed
• Branch is up-to-date with base branch
• Related issue number is identified, or placeholder is used
• PR description follows the template exactly
• Appropriate type of change is selected
• Pre-flight checklist items are addressed
