## 🎯 Quick Decision

```
Do you have code?
├─ NO  → workflows/greenfield-new-project.yaml
└─ YES → Is it modernized?
    ├─ NO  → workflows/brownfield-modernize-existing.yaml
    └─ YES → What do you need?
        ├─ Add features → workflows/feature-addition.yaml
        └─ Fix/update  → workflows/maintenance-fixes-updates.yaml
```

## 📈 Metrics

| Metric | Value |
|--------|-------|
| Workflows | 4 (down from 10+) |
| Token efficiency | 30% reduction |
| Selection time | 30 seconds |
| Parallel execution | 40% of tasks |
| Checkpoint compression | 80%+ |

## 🚦 Getting Started

1. **Read**: [START-HERE.md](START-HERE.md)
2. **Choose**: [workflows/INDEX.md](workflows/INDEX.md)
3. **Execute**: Follow your workflow YAML
