# Create Pull Request

Create a GitHub pull request with a clear title, structured description, and proper branch setup.

## When to Use

- Proposing changes from a feature or fix branch for review
- Merging completed work into the main branch
- Requesting code review from collaborators
- Documenting the purpose and scope of a set of changes

## Inputs

- **Required**: Feature branch with committed changes
- **Required**: Base branch to merge into (usually `main`)
- **Optional**: Reviewers to request
- **Optional**: Labels or milestone
- **Optional**: Draft status

## Procedure

### Step 1: Ensure Branch Is Ready

Verify the branch is up to date with the base branch and all changes are committed:

```bash
# Check for uncommitted changes
git status

# Fetch latest from remote
git fetch origin

# Rebase on latest main (or merge)
git rebase origin/main
```

**Expected:** Branch is ahead of `origin/main` with no uncommitted changes and no conflicts.

**On failure:** If rebase conflicts occur, resolve them (see `resolve-git-conflicts` skill), then `git rebase --continue`. If the branch has diverged significantly, consider `git merge origin/main` instead.

### Step 2: Review All Changes on the Branch

Examine the full diff and commit history that will be included in the PR:

```bash
# See all commits on this branch (not on main)
git log origin/main..HEAD --oneline

# See the full diff against main
git diff origin/main...HEAD

# Check if branch tracks remote and is pushed
git status -sb
```

**Expected:** All commits are relevant to the PR. The diff shows only intended changes.

**On failure:** If unrelated commits are present, consider interactive rebase to clean up history before creating the PR.

### Step 3: Push the Branch

```bash
# Push branch to remote (set upstream tracking)
git push -u origin HEAD
```

**Expected:** Branch appears on GitHub remote.

**On failure:** If push is rejected, pull first with `git pull --rebase origin <branch>` and resolve any conflicts.

### Step 4: Write PR Title and Description

Keep the title under 70 characters. Use the body for details:

```bash
gh pr create --title "Add weighted mean calculation" --body "$(cat <<'EOF'
## Summary
- Implement `weighted_mean()` with NA handling and zero-weight filtering
- Add input validation for mismatched vector lengths
- Include unit tests covering edge cases

## Test plan
- [ ] `devtools::test()` passes with no failures
- [ ] Manual verification with example data
- [ ] Edge cases: empty vectors, all-NA weights, zero-length input

🤖 Generated with [Claude Code](https://claude.com/claude-code)
EOF
)"
```

For draft PRs:

```bash
gh pr create --title "WIP: Add authentication" --body "..." --draft
```

**Expected:** PR created on GitHub with a URL returned. Description clearly communicates what changed and how to test.

**On failure:** If `gh` is not authenticated, run `gh auth login`. If the base branch is wrong, specify with `--base main`.

### Step 5: Handle Review Feedback

Respond to review comments and push updates:

```bash
# View PR comments
gh api repos/{owner}/{repo}/pulls/{number}/comments

# View PR review status
gh pr checks

# After making changes, commit and push
git add <files>
git commit -m "$(cat <<'EOF'
fix: address review feedback on input validation

EOF
)"
git push
```

**Expected:** New commits appear on the PR. Review comments are addressed.

**On failure:** If CI checks fail after pushing, read the check output with `gh pr checks` and fix the issues before requesting re-review.

### Step 6: Merge and Clean Up

After approval:

```bash
# Merge the PR (squash merge keeps history clean)
gh pr merge --squash --delete-branch

# Or merge with all commits preserved
gh pr merge --merge --delete-branch

# Or rebase merge (linear history)
gh pr merge --rebase --delete-branch
```

After merge, update local main:

```bash
git checkout main
git pull origin main
```

**Expected:** PR is merged, remote branch is deleted, local main is updated.

**On failure:** If merge is blocked by failing checks or missing approvals, address those first. Do not force-merge without resolving blockers.

## Validation

- [ ] PR title is concise (under 70 characters) and descriptive
- [ ] PR body includes summary of changes and test plan
- [ ] All commits on the branch are relevant to the PR
- [ ] CI checks pass
- [ ] Branch is up to date with base branch
- [ ] Reviewers are assigned (if required by repository settings)
- [ ] No sensitive data in the diff

## Common Pitfalls

- **PR too large**: Keep PRs focused on a single feature or fix. Large PRs are harder to review and more likely to have merge conflicts.
- **Missing test plan**: Always describe how the changes can be verified, even for documentation PRs.
- **Stale branch**: If the base branch has moved ahead significantly, rebase before creating the PR to minimize merge conflicts.
- **Force-pushing during review**: Avoid force-pushing to a branch with open review comments. Push new commits so reviewers can see incremental changes.
- **Not reading CI output**: Check `gh pr checks` before asking for re-review. Failing CI wastes reviewers' time.
- **Forgetting to delete branch**: Use `--delete-branch` with merge to keep the remote clean.
