# 🚀 Agent Orchestration Master Plan
> **Mission:** Build the complete x402 Facilitator infrastructure in parallel using 5 specialized agents.
## 📋 Overview
This document coordinates 5 Opus 4.5 agents working in parallel on the **x402 Facilitator Server** - our first major revenue stream. Each agent has a specific domain and clear handoff points.
## 🎯 Project Goal
Build a production-ready x402 Facilitator that:
1. Processes x402 payments across EVM and Solana chains
2. Takes 0.1% fee on each transaction
3. Provides analytics dashboard
4. Runs in Docker with full monitoring
5. Integrates with our existing marketplace
## 📊 Agent Assignments
| Agent | Domain | Primary Files | Dependencies |
|-------|--------|---------------|--------------|
| **Agent 1** | Facilitator Core Engine | `packages/facilitator/src/core/` | None (starts first) |
| **Agent 2** | Settlement & Multi-Chain | `packages/facilitator/src/settlement/` | Agent 1 interfaces |
| **Agent 3** | REST API & WebSocket | `packages/facilitator/src/api/` | Agent 1 + 2 types |
| **Agent 4** | Monitoring & Analytics | `packages/facilitator/src/analytics/` | Agent 1-3 events |
| **Agent 5** | Deployment & Docs | `deploy/facilitator/`, docs | All agents |
## 🔄 Workflow
```
Phase 1 (Parallel): Agents 1-4 start simultaneously
Phase 2 (Integration): Agent 5 integrates, all agents test
Phase 3 (Polish): Bug fixes, optimization, documentation
Phase 4 (Launch): Deployment, monitoring, handoff to next project
```
