# Complete Git Workflow with Multi-Agent Orchestration

Orchestrate a comprehensive git workflow from code review through PR creation, leveraging specialized agents for quality assurance, testing, and deployment readiness. This workflow implements modern git best practices including Conventional Commits, automated testing, and structured PR creation.

[Extended thinking: This workflow coordinates multiple specialized agents to ensure code quality before commits are made. The code-reviewer agent performs initial quality checks, test-automator ensures all tests pass, and deployment-engineer verifies production readiness. By orchestrating these agents sequentially with context passing, we prevent broken code from entering the repository while maintaining high velocity. The workflow supports both trunk-based and feature-branch strategies with configurable options for different team needs.]

## Configuration

**Target branch**: $ARGUMENTS (defaults to 'main' if not specified)

**Supported flags**:
- `--skip-tests`: Skip automated test execution (use with caution)
- `--draft-pr`: Create PR as draft for work-in-progress
- `--no-push`: Perform all checks but don't push to remote
- `--squash`: Squash commits before pushing
- `--conventional`: Enforce Conventional Commits format strictly
- `--trunk-based`: Use trunk-based development workflow
- `--feature-branch`: Use feature branch workflow (default)

        suggestions = analyze_split_opportunities(analysis)
        
        return f"""
## ⚠️ Large PR Detected

This PR changes {stats['files_changed']} files with {stats['insertions'] + stats['deletions']} total changes.
Large PRs are harder to review and more likely to introduce bugs.

### Suggested Splits:

{format_split_suggestions(suggestions)}

### How to Split:

1. Create feature branch from current branch
2. Cherry-pick commits for first logical unit
3. Create PR for first unit
4. Repeat for remaining units

```bash
# Example split workflow
git checkout -b feature/part-1
git cherry-pick <commit-hashes-for-part-1>
git push origin feature/part-1
# Create PR for part 1

git checkout -b feature/part-2
git cherry-pick <commit-hashes-for-part-2>
git push origin feature/part-2
# Create PR for part 2
```
"""
