Creating Tools

Learn how to create custom tools that extend your agent’s capabilities.

​
Tool Creation Overview

Tools are modular components that add specific functionalities to your agents. They can range from simple utility functions to complex integrations with external services.

​
Tool Components

Interface

  • Input/Output definitions
  • Parameter types
  • Return values

Logic

  • Core functionality
  • Business rules
  • Processing steps

Configuration

  • Settings
  • Options
  • Defaults

Documentation

  • Usage guide
  • Examples
  • API reference

​
Creating a Tool

1

Define Interface

Specify tool interface
  • Define inputs
  • Specify outputs
  • Set parameters
2

Implement Logic

Build core functionality
  • Write business logic
  • Handle errors
  • Add validation
3

Configure Settings

Set up tool configuration
  • Default values
  • Options
  • Limits
4

Add Documentation

Document the tool
  • Usage guide
  • Examples
  • API docs

​
Tool Structure

interface Tool {
  name: string;
  description: string;
  version: string;
  parameters: Parameter[];
  returns: ReturnType;
}

interface Parameter {
  name: string;
  type: string;
  required: boolean;
  default?: any;
}

class CustomTool implements Tool {
  async execute(params: any): Promise<Result> {
    // Validate inputs
    this.validateParams(params);
    
    // Process
    const result = await this.process(params);
    
    // Return results
    return this.formatResponse(result);
  }
}

{
  "tool": {
    "name": "data_processor",
    "version": "1.0.0",
    "settings": {
      "timeout": 5000,
      "retry_count": 3,
      "cache_enabled": true
    }
  }
}

​
Tool Examples

export class DataProcessor implements Tool {
  name = 'data_processor';
  description = 'Process and transform data';
  
  async execute(data: any): Promise<Result> {
    // Implementation
    return processedData;
  }
}

​
Best Practices

Modularity

Keep tools focused and modular

Error Handling

Implement robust error handling

Documentation

Provide clear documentation

Testing

Thoroughly test functionality

​
Testing Tools

1

Unit Testing

Test individual components
2

Integration Testing

Test with other tools
3

Performance Testing

Check resource usage
4

User Testing

Validate usability
