Pull Request

$ARGUMENTS

Create a GitHub pull request.

Project context

• Recent commits: !git log --oneline main..HEAD 2>/dev/null | head -20

Usage

/pr [title]

Automated PR Summary Generation

Generate a structured PR summary from the commit history before writing the PR description:

python3 ${CLAUDE_SKILL_DIR}/scripts/pr-summary.py [base_branch]
# Default base branch: main
# Example: python3 ${CLAUDE_SKILL_DIR}/scripts/pr-summary.py develop

The script outputs JSON with:

• title_suggestion: auto-generated PR title from dominant commit type and scope
• commits[]: each commit parsed into type, scope, description (conventional commits)
• groups: commits grouped by type (Features, Bug Fixes, etc.)
• summary_bullets: ready-to-use summary lines for the PR body
• has_breaking: whether any BREAKING CHANGE markers were found
• breaking_changes[]: list of breaking change descriptions
• files_changed: total files in the diff
• test_files_changed: count of test files modified
• has_tests: whether the PR includes test changes

Use the output to populate the PR template fields below.

PR Creation Workflow

1. Pre-PR Checks

# Run CI checks
ruff check . && mypy src/ && pytest tests/

# Check branch status
git status
git diff main...HEAD --stat

2. Create PR

gh pr create --title "feat: add multi-hop reasoning" --body "$(cat <<'EOF'
## Summary
- Implement query decomposition for complex questions
- Add iterative retrieval with reasoning
- Include answer synthesis from aggregated context

## Test plan
- [ ] Unit tests pass
- [ ] Integration tests pass
- [ ] Manual testing with sample queries

PR Checklist

Before creating PR:

• All tests pass: pytest tests/
• Linting passes: ruff check .
• Type checking passes: mypy src/
• Documentation updated if needed
• Commit messages follow conventional commits
• Branch is up to date with main

Useful gh Commands

# View PR
gh pr view

# Check PR status
gh pr checks

# Request review
gh pr edit --add-reviewer username

# Merge PR
gh pr merge --squash

Rules

• MUST run lint + typecheck + tests locally before opening the PR
• NEVER force-push main or master
• NEVER add Co-Authored-By: Claude or other AI attribution to commits
• CRITICAL: PR body must include a Test plan checklist — no exceptions
• MANDATORY: commit messages follow conventional commits (feat:, fix:, docs: etc.)

Gotchas

• gh pr merge --squash drops all original commit trailers, including Co-Authored-By: lines. If the PR had legitimate co-authors, note them in the squashed commit body or use --rebase instead.
• gh defaults to github.com; for GitHub Enterprise the host must be set per-repo with gh auth login --hostname <host> and gh repo set-default. Silent failures on enterprise usually mean the wrong host.
• Running gh pr create without --body opens an editor ($EDITOR or vi) — in non-interactive contexts this hangs indefinitely. Always pass --body or --body-file.
• The pre-flight ruff check . walks respecting .gitignore by default but mypy src/ does not — if src/ contains generated code excluded from git, mypy will still scan it and report spurious errors.
• git diff main...HEAD (triple dot) shows commits on HEAD since the merge-base; git diff main..HEAD (double dot) shows all differences including main's newer commits. Use triple-dot for PR-scope diffs.

When NOT to Use

• For creating a commit (without a PR) — use /commit
• For reviewing a PR someone else opened — use /review
• For drafting release notes across many PRs — use /docs or a release script
• When the branch has uncommitted changes — commit first, then open the PR
