Creating Custom Agents

Creating custom agents in AgentScope AI allows developers to build specialized AI-powered assistants tailored to specific workflows, data sources, and functionalities. This document provides a step-by-step guide to creating custom agents using AgentScope AI, covering the agent structure, configuration, and integration with external APIs and tools.

Understanding Agent Structure

An agent in AgentScope AI consists of the following key components:

• Instructions: Defines the agent's purpose and behavior.

• Model Configuration: Specifies the underlying AI model.

• Tools and Integrations: Allows the agent to interact with external APIs and services.

• Memory and Context: Enables the agent to retain information across interactions.

Setting Up a Custom Agent

To create a custom agent, follow these steps:

1. Install AgentScope AI SDK

Ensure you have the AgentScope AI SDK installed in your development environment:

npm install @agentscope/core

2. Define the Agent

Create a new file in your project directory, e.g., customAgent.ts, and define your agent:

import { Agent } from "@agentscope/core";
import * as tools from "./tools";

export const customAgent = new Agent({
  name: "Custom AI Agent",
  instructions: "You are a specialized assistant designed to analyze and respond to queries efficiently.",
  model: {
    provider: "OPEN_AI",
    name: "gpt-4",
    toolChoice: "auto",
  },
  tools: {
    fetchData: tools.fetchData,
    analyzeSentiment: tools.analyzeSentiment,
  },
  memory: true,
});

3. Register the Agent

To make the agent available in your application, register it in the main initialization file:

import { AgentScope } from "@agentscope/core";
import { customAgent } from "./customAgent";

export const agentscope = new AgentScope({
  agents: { customAgent },
});

4. Using the Custom Agent

You can now interact with your custom agent by calling its generate function:

import { agentscope } from "./index";

async function main() {
  const agent = agentscope.getAgent("customAgent");
  const response = await agent.generate("What is the latest trend in AI?");
  
  console.log(response.text);
}

main();

Debugging and Testing Agents

Testing is essential to ensure the agent performs as expected. Use Vitest or another testing framework to validate its functionality:

test("Agent should return a response", async () => {
  const agent = agentscope.getAgent("customAgent");
  const response = await agent.generate("Test query");
  expect(response.text).toBeDefined();
});
