- **Testing Results**: Backward compatibility validation complete
- **Creator Package**: Ready for discussion and approval
After Creator Approval & Phase 2-3:
- **Dev Agent**: Enhanced but still lean (target: <80 lines, 3 dependencies)
- **Planning Agents**: Rich context capabilities (6-8 dependencies each)
- **Cross-Agent Workflow**: Seamless context transfer and collaboration
- **Framework Integrity**: 100% BMad Method compliance maintained
