## Introduction

The O-RAN Software Community (O-RAN SC) and the Nephio project represent significant efforts to transform Radio Access Networks (RAN) through open, intelligent, and cloud-native architectures. O-RAN Alliance members have committed to building future RANs on virtualized network elements, white-box hardware, and standardized interfaces that embrace principles of intelligence and openness.

However, the complexity of deploying and managing multi-vendor, multi-site O-RAN implementations remains a significant challenge. Current orchestration methods—often brittle, imperative, and fire-and-forget—struggle to handle the dynamic capabilities of modern distributed cloud platforms.

This article presents a novel approach using Claude Code's subagent system to create specialized AI agents that automate the entire O-RAN deployment lifecycle, from infrastructure provisioning to performance optimization.

## Problem Statement

### Current Challenges in O-RAN Deployment

Modern O-RAN deployments face several critical challenges:

1. **Complexity at Scale**: A typical deployment involves 100+ network functions across 10,000+ edge sites, resulting in millions of configuration parameters
2. **Multi-Domain Expertise**: Requires coordination between network planning, infrastructure, security, and application teams
3. **Vendor Heterogeneity**: Integration of components from multiple vendors with different interfaces and models
4. **Dynamic Infrastructure**: Managing ephemeral cloud-native infrastructure with continuous changes
5. **Operational Overhead**: Manual processes leading to errors and extended deployment times

### Quantifying the Impact

Consider a real-world scenario:
- **100 parameters** per network function
- **100 network functions** per deployment
- **10,000 edge clusters**
- **= 100,000,000 configuration decisions**

This scale requires data management techniques, not traditional code-based approaches.

## Solution Architecture

### High-Level Design

The solution implements a hierarchical multi-agent system based on Nephio's configuration-as-data principle and Claude Code's subagent capabilities:

handoff_to: "oran-nephio-dep-doctor"
artifacts:
  - type: "kubeconfig"
    name: "cluster-access"
    content: |
      # Kubernetes configuration

## Multi-Agent Orchestration

### Workflow Definition

The system implements four pre-defined workflows using declarative YAML:

name: complete-deployment
description: "End-to-end O-RAN deployment with Nephio R5"
stages:
  - name: infrastructure
    agent: nephio-infrastructure-agent
    timeout: 600s
    critical: true
    
  - name: dependencies
    agent: oran-nephio-dep-doctor
    timeout: 300s
    critical: true
    
  - name: configuration
    agent: configuration-management-agent
    timeout: 450s
    critical: true
    
  - name: network-functions
    agent: oran-network-functions-agent
    timeout: 900s
    critical: true
    
  - name: monitoring
    agent: monitoring-analytics-agent
    timeout: 300s
    critical: false
    
  - name: optimization
    agent: performance-optimization-agent
    timeout: 600s
    critical: false

### State Management

The orchestration engine maintains workflow state across agent executions:

class WorkflowState:
    def __init__(self, workflow_id):
        self.workflow_id = workflow_id
        self.state_dir = Path.home() / ".claude-workflows" / workflow_id
        self.state = {
            "workflow_id": workflow_id,
            "started_at": datetime.now().isoformat(),
            "status": "running",
            "stages": {},
            "artifacts": {}
        }
