• Benchmark support (CIS, DISA STIG, etc.)
• Helper methods for common workflows
• Integration with InsightVMClient
• Comprehensive docstrings with type hints
• Error handling
• Unit tests (when test framework ready)

API Endpoints

• GET /api/3/policies - List all policies
• GET /api/3/policies/{id} - Get policy details
• GET /api/3/policies/{id}/groups - Get policy groups
• GET /api/3/policies/{id}/groups/{groupId} - Get group details
