Experimental multi-agent system demonstrating AI agent orchestration patterns that are vendor SDK agnostic:

πŸ”¬ Core Hypotheses

This experimental system tests two fundamental hypotheses about AI-assisted development and multi-agent architectures:

Hypothesis 1: Domain based Tool Agnostic Agent Architecture

"Business logic can be completely separated from agent SDK implementation through configuration-driven design"

The system demonstrates:

  • Multi-Agent Orchestration Patterns: Sequential (implemented), Parallel, Conditional, and Hierarchical (planned)
  • Domain-Driven Agent Personas: Agent behaviors crafted from loan industry expertise and market analysis
  • Business Logic in Configuration: YAML/Markdown files instead of code
  • Multiple Agent SDK Support: Provider model enables OpenAI, Autogen, Semantic Kernel integration
  • Separation of Concerns: Clean boundaries between agents, orchestration, and business logic

Results:

Hypothesis 2: Human-AI Team Development

"One human developer can effectively orchestrate a team of specialized AI sub-agents to build complex systems"

This repository was built using Claude Code as the primary developer, working with specialized sub-agents:

  • πŸ—οΈ System Architecture Reviewer - Validated design decisions and system impacts
  • πŸ” Code Reviewer - Ensured code quality and architectural alignment
  • πŸ“Š Product Manager Advisor - Aligned features with business value
  • 🎨 UX/UI Designer - Validated user experience decisions
  • πŸš€ GitOps CI Specialist - Managed Git operations and CI/CD pipeline success

Results:


πŸ€– Demonstrating Human-AI Team Development: This repository proves that one human can orchestrate a team of specialized AI agents to build complex, well-architected systems. Built entirely through Claude Code + specialized sub-agents collaboration in 72 hours.

Current Scope: We've tested with one agent SDK (OpenAI Agents SDK) and one orchestration pattern (sequential). We're still learning and will expand to more SDKs and patterns as we evolve. Learn about our approach β†’

Key Features

  • βœ… Multi-Agent Orchestration: Sequential, parallel, and conditional coordination patterns
  • βœ… Multiple Framework Support: Business logic separated from SDK - supports OpenAI, Semantic Kernel, Autogen through provider model
  • βœ… Configuration-Driven Design: YAML-based agent creation and orchestration without code changes
  • βœ… MCP Tool Servers: Agents autonomously select from 15+ tools across 3 specialized servers
  • βœ… Type-Safe Communication: Pydantic models ensure structured data validation between agents
  • βœ… Observable Agent Interactions: OpenTelemetry integration tracks decisions, handoffs, and performance
  • βœ… AI-Powered Development: Built using Claude Code with 5 specialized development agents

Business Impact Projections

Performance metrics and cost reduction claims are AI-generated projections based on typical loan processing analysis and have not been independently benchmarked. Actual results depend on:

  • System complexity and integration requirements
  • Regulatory environment and compliance obligations
  • Data characteristics and processing volume
  • Implementation approach and team expertise

A living experiment in configuration-driven, vendor-agnostic multi-agent orchestration

The Business Impact (AI-Projected Estimates)

Current State With Multi-Agent System Projected Gain*
3-5 days processing 3-5 minutes 99.8% faster
$50-75 per application $6-10 per application 88% cost reduction

  • Parallel Evaluation: Independent agents work simultaneously (planned)
  • Conditional Routing: Dynamic workflow based on application characteristics (planned)
  • Context Accumulation: Each agent enriches shared context for better decisions

πŸ“‹ Agent Registry: Configuration-Driven Architecture

Our system uses a configuration-first approach to agent management:

Simple YAML Configuration

agents:
  intake:
    name: "Intake Agent"
    persona_file: "intake"
    mcp_servers: ["application_verification"]
    capabilities: ["Application validation", "Identity verification"]

Automatic Agent Creation

# No more complex initialization code
from loan_processing.agents.providers.openai.agentregistry import AgentRegistry

agent = AgentRegistry.create_agent("intake", model="gpt-4")

Provider Flexibility

# Switch providers through configuration
provider_config:
  openai:           # Current implementation
    model: "gpt-4"
  semantic_kernel:  # Future support
    model: "gpt-4"
  autogen:         # Planned integration
    model: "gpt-4"

Quick Start (3 Steps)

# 1. Clone and install (using uv package manager)
git clone https://github.com/niksacdev/multi-agent-system.git
cd multi-agent-system
uv sync

# 2. Configure your API provider
cp .env.example .env
# Edit .env with your OpenAI or Azure OpenAI credentials

# 3. Interactive startup - one command does it all!
./start.sh          # Unix/Linux/macOS  
# OR
start.bat           # Windows

Experience the magic! The interactive startup script:

  • βœ… Checks your environment automatically
  • πŸš€ Starts all MCP data services with progress indicators
  • πŸŽ‰ Waits for everything to be ready
  • πŸ€– Prompts you when ready to process loans
  • 🧹 Cleans up everything when you exit

πŸ”§ Alternative: Manual Setup

If you prefer more control, you can start components separately:

# Option 1: Start MCP servers first, then console app
python start_mcp_servers.py
uv run python run_console_app.py

# Option 2: Check server status
python start_mcp_servers.py --status

# Option 3: Stop servers manually  
python start_mcp_servers.py --stop
