Implementation Details

Agent Implementation

The Material Expert is a UserFacingAgent type that implements specialized methods for material information tasks:

export class MaterialExpert implements UserFacingAgent {
  // Standard UserFacingAgent properties
  public id: string;
  public type: AgentType;
  public name: string;
  public description: string;
  public agent: Agent;
  public config: AgentConfig;

  // Material-specific methods
  public async processUserInput(message: string): Promise<string>;
}

Agent Tools

The Material Expert leverages specialized tools to perform its tasks:

// Tool for searching materials in the database
const materialSearchTool = await createMaterialSearchTool();

// Tool for performing vector-based similarity searches
const vectorSearchTool = await createVectorSearchTool();

// Create a Material Expert with tools
const tools = [
  materialSearchTool,
  vectorSearchTool
];

// Additional tools can be added from the configuration
if (config.additionalTools) {
  tools.push(...config.additionalTools);
}

Agent Description

The Material Expert is defined with the following characteristics:

const agent = new Agent({
  name: 'Material Expert',
  role: 'Construction material specialist with deep knowledge of materials and their properties',
  goal: 'Provide accurate and detailed information about construction materials to help users make informed decisions',
  backstory: 'With years of experience in material science and construction, I can identify materials, explain their properties, and recommend the best options for specific applications.',
  verbose: config.verbose || false,
  llm: modelSettings,
  tools
});

Client-Side Integration

The Material Expert is integrated into the client interface through a specialized panel that provides:

Chat Interface - For asking questions about materials
Material Display - For viewing detailed information about materials
Comparison View - For comparing multiple materials side-by-side
Related Materials - For discovering similar or complementary materials

Setup Instructions

Prerequisites

Functioning KAI platform with material database
CrewAI integration set up according to CrewAI installation guide
Vector search capabilities for material similarity

Installation

The Material Expert is included in the standard crewAI integration package:

# Navigate to the agents directory
cd packages/agents

# Install dependencies if not already done
yarn install

Configuration

Configure the agent in your application initialization:

import  from '@kai/agents';

// Create a Material Expert instance
const materialExpert = await createMaterialExpert(
  {
    id: 'material-expert-1',
    name: 'Material Expert',
    description: 'Expert in construction materials and their properties',
    verbose: true,
    // Additional configuration options
  },
  {
    model: 'gpt-4',
    temperature: 0.3
  }
);

Usage Examples

Client-Side Integration

import React from 'react';
import  from '../components/agents/MaterialExpertPanel';

const MaterialExpertPage: React.FC = () => {
  return (
    <div className="material-expert-page">
      <h1>Material Expert</h1>
      <MaterialExpertPanel />
    </div>
  );
};

export default MaterialExpertPage;

Processing User Queries

import  from '@kai/agents';

// Create the Material Expert
const materialExpert = await createMaterialExpert(
  ,
  
);

// Ask questions about materials
const query1 = 'What are the key differences between ceramic and porcelain tiles?';
const response1 = await materialExpert.processUserInput(query1);
console.log(response1);

const query2 = 'What material would you recommend for a bathroom floor that needs to be water-resistant and durable?';
const response2 = await materialExpert.processUserInput(query2);
console.log(response2);

const query3 = 'Are concrete countertops compatible with epoxy sealants?';
const response3 = await materialExpert.processUserInput(query3);
console.log(response3);

Advanced Configuration

Custom Material Analysis Tools

Create custom tools to enhance the Material Expert's capabilities:

import  from 'crewai';

// Create a specialized material analysis tool for environmental impact
const createEnvironmentalImpactTool = async (): Promise<Tool> => {
  return new Tool({
    name: 'environmental_impact_analysis',
    description: 'Analyze the environmental impact of materials based on lifecycle assessment data',
    func: async (args) => {
      const { materialId } = JSON.parse(args);
      
      // Implement environmental impact analysis
      const impactData = await analyzeMaterialEnvironmentalImpact(materialId);
      
      return JSON.stringify({
        carbonFootprint: impactData.carbonFootprint,
        energyConsumption: impactData.energyConsumption,
        waterUsage: impactData.waterUsage,
        recycleability: impactData.recycleability,
        sustainabilityScore: impactData.overallScore
      });
    }
  });
};

// Add it to the agent
const materialExpert = await createMaterialExpert(
  { 
    id: 'eco-material-expert-1',
    additionalTools: [await createEnvironmentalImpactTool()]
  },
  
);

Integration with Material Testing Data

Connect the Material Expert to material testing databases:

import  from 'crewai';

// Create a tool for accessing material testing data
const createMaterialTestingTool = async (): Promise<Tool> => {
  return new Tool({
    name: 'material_testing_data',
    description: 'Access technical testing data for materials including stress tests, durability metrics, etc.',
    func: async (args) => {
      const { materialId, testType } = JSON.parse(args);
      
      // Implement testing data retrieval
      const testingData = await getMaterialTestResults(materialId, testType);
      
      return JSON.stringify(testingData);
    }
  });
};

// Add it to the agent
const materialExpert = await createMaterialExpert(
  { 
    id: 'technical-material-expert-1',
    additionalTools: [await createMaterialTestingTool()]
  },
  
);

Performance Considerations

Knowledge Base Optimization

Caching Strategy
- Cache frequently requested material information
- Implement TTL-based cache invalidation for freshness
- Pre-compute common material comparisons
Query Optimization
- Use indexed material properties for faster lookups
- Implement faceted search for filtered queries
- Optimize vector searches with approximate nearest neighbors
Response Construction
- Build responses with templated sections where appropriate
- Use progressive loading for detailed material information
- Structure responses for optimal client-side rendering

Security Considerations

Data Access Control
- Enforce appropriate permissions for proprietary material data
- Implement proper user authentication for premium material information
- Limit access to sensitive supplier or pricing information
Information Accuracy
- Verify material information against reliable sources
- Provide provenance for technical material specifications
- Implement fact-checking mechanisms for critical properties
Agent Boundaries
- Restrict the agent to material-related operations
- Validate inputs to prevent injection attacks
- Avoid providing professional advice that requires certification
