RenewableOps AI Assistant - Part 3

This blog posts focuses on the multi-agent implementation details, guardrails based on AWS Agent Squad, AWS Bedrock, and AWS Nova models

Building on the foundation laid in Part 1 (multi-agent architecture overview) and Part 2 (model economics and evaluation), this post delves into the architecture, advanced implementation patterns, and real-world deployment strategies that make our renewable energy AI system enterprise-grade.

While the previous parts focused on the "what" and "why" of our solution, Part 3 explores the "how" – the technical intricacies, scalability considerations, and operational excellence practices that transform a proof-of-concept into a robust system with multi-agent collaboration.

Advanced Multi-Agent Architecture Patterns

The Agent Squad Framework: Beyond Basic Orchestration

Our implementation leverages the AWS Agent Squad framework, which represents a significant evolution from traditional multi-agent patterns. The framework implements sophisticated coordination mechanisms that enable both hierarchical delegation and parallel processing while maintaining contextual awareness across agent interactions.

The core architecture implements what we call the "agents-as-tools" pattern, where specialized agents are exposed as intelligent tools that supervisory agents can invoke dynamically. This mirrors human organizational structures where project managers don't need domain expertise in every area – they simply need to know which specialist to consult for each task.

Key architectural components include:

  • Agent Squad Classifier: Uses Amazon Nova Pro for intelligent query routing based on intent analysis, conversation history, and agent capabilities. The classifier achieves 94% routing accuracy through sophisticated prompt engineering and few-shot learning examples.
  • Supervisor Agents: Implement Amazon Nova Pro-powered orchestration with the ability to coordinate multiple team members simultaneously. These agents can process queries requiring multiple expertise areas in parallel, significantly reducing response latency.
  • Specialized Team Agents: Each agent optimized for specific domains using the most cost-effective Nova model variant. Wind turbine operations leverage Nova Lite for technical documentation, while solar insights utilize Nova Pro for complex calculations

The configuration below shows how the system maintains reliability through retry mechanisms, execution logging, and conversation limits that prevent infinite loops while preserving context

orchestrator = AgentSquad(options=AgentSquadConfig(
    LOG_AGENT_CHAT=True,
    LOG_CLASSIFIER_CHAT=True,
    LOG_EXECUTION_TIMES=True,
    MAX_RETRIES=3,
    USE_DEFAULT_AGENT_IF_NONE_IDENTIFIED=True,
    MAX_MESSAGE_PAIRS_PER_AGENT=10,
))

Production-Grade Knowledge Management

Scalable RAG Architecture with Amazon Bedrock Knowledge Bases

Our knowledge management system utilizes Amazon Bedrock Knowledge Bases to implement a fully managed RAG solution that abstracts the complexity of vector database operations. The system automatically handles document ingestion, chunking, embedding generation, and similarity search across multiple data sources.

  • Multi-Modal Knowledge Integration: The system processes both structured and unstructured data sources:
    • Structured Data: DynamoDB tables containing wind turbine specifications, maintenance records, and performance metrics
    • Unstructured Data: Technical manuals, troubleshooting guides, and regulatory documentation stored in Amazon S3
    • Image Data: Visual inspection reports, and component photographs for automated analysis
  • Knowledge Base Optimization: Each domain maintains separate knowledge bases optimized for specific query patterns:
    • Wind Turbine Knowledge Base: Technical documentation, maintenance procedures, and troubleshooting guides
    • Solar Panel Knowledge Base: Installation guides, cost analysis data, and performance optimization resources
    • Regulatory Knowledge Base: Compliance documentation and industry standards across different jurisdictions

Advanced Retrieval and Ranking Strategies

The system implements sophisticated retrieval mechanisms that go beyond simple semantic similarity. Each knowledge base query includes:

  • Contextual Filtering: Metadata-based filtering ensures agents only access relevant information for their specific domain and user context.
  • Hybrid Search Patterns: Combining semantic search with keyword-based filtering for improved retrieval accuracy, particularly important for technical documentation where exact terminology matters.
  • Reranking Models: Integration with Amazon Bedrock's reranking capabilities to improve result relevance based on query intent and user context.

Serverless Architecture for Enterprise Scale

Lambda-Based Agent Deployment

Our serverless architecture leverages AWS Lambda for agent deployment, providing automatic scaling and cost optimization. Each agent type is packaged as a separate Lambda function with specific resource allocations:

  • Wind Turbine Image Analysis Agent: 1-minute timeout for complex computer vision tasks, with provisioned concurrency during peak inspection periods.
  • Solar Panel Catalog Agent: 3-second timeout for rapid query processing, with automatic scaling based on demand patterns.
  • Utility Bill Analysis Agent: Specialized function for extracting financial data from utility bills, with enhanced security controls for sensitive information processing.

Event-Driven Orchestration

The system implements sophisticated event-driven patterns that enable asynchronous processing and improved fault tolerance. Key patterns include:

  • Orchestrator-Worker Pattern: Central orchestrator distributes tasks across worker agents using partitioned topics, enabling horizontal scaling and load distribution.
  • Hierarchical Agent Coordination: Multi-level orchestration where supervisor agents act as both workers for higher-level coordination and orchestrators for their specialized teams.
  • Blackboard Pattern: Shared knowledge state maintained across agents through event streaming, enabling collaborative problem-solving for complex renewable energy scenarios.

Model Context Protocol (MCP) Integration

Standardized Tool Integration

Our system implements the Model Context Protocol (MCP) for standardized tool integration. This enables seamless connection to external APIs and services:

  • Google Maps Solar API Integration: The Solar Insights Agent utilizes MCP to connect with Google's Solar API for roof analysis and solar potential calculations.
  • Google Maps Geo API Integration: Geocode conversion from user provided address to latitude and longitude

MCP Server Architecture

The MCP implementation follows a client-server architecture where agents act as MCP clients connecting to specialized servers

# MCP client implementation for Solar Insights Agent
from mcp.client import MCPClient

class SolarInsightsAgent:
    def __init__(self):
        self.mcp_client = MCPClient()
        self.google_solar_server = self.mcp_client.connect_server("google-solar-api")
    
    async def get_solar_potential(self, address):
        return await self.google_solar_server.request("get_solar_potential", {
            "address": address,
            "quality": "high"
        })


Security and Compliance Framework

Multi-Layer Security Architecture

Our system implements comprehensive security measures across multiple layers:

  • Identity and Access Management: Fine-grained IAM roles for each agent type with principle of least privilege access to specific resources.
  • Amazon Bedrock Guardrails: Comprehensive content filtering and safety mechanisms configured for renewable energy contexts:
    • Content filters blocking inappropriate technical discussions
    • Denied topics preventing tax credit advice queries
    • Prompt attack detection preventing system manipulation
  • Network Security: VPC isolation for sensitive operations, with security groups restricting access to specific Lambda functions and knowledge bases.
