# Plurality AI Agents

Plurality AI Agents is a lightweight, ergonomic TypeScript library for multi-agent orchestration.

## Features

🤖 Advanced Agent Management

- Create and orchestrate multiple agents with unique behaviors and specializations
- Fine-tune agent personalities and knowledge bases for diverse use cases

🧠 Seamless Function Integration

- Easily integrate custom functions into agent workflows for enhanced capabilities

🔄 Dynamic Function Execution

- Execute functions dynamically based on agent context and user needs

🌊 Real-time Streaming Responses

- Efficiently handle and display streaming responses from the Swarm API
- Implement progress indicators and partial updates for enhanced user experience

📘 Full TypeScript Support

- Enjoy a fully typed library for improved code quality and maintainability
- Benefit from intelligent autocomplete and catch potential errors early

🔍 Comprehensive Debugging

- Activate debug mode for in-depth logging and performance analysis

## Installation

Install Plurality using npm:

```bash
npm install @pluralityai/agents
```

or

```bash
yarn add @pluralityai/agents
```

or

```bash
pnpm add @pluralityai/agents
```

## Usage

Before using Plurality, you need to set up your OpenAI API key. You have three options:

1. Set the OPENAI_API_KEY environment variable.
2. Pass the API key directly when initializing the Swarm instance.
3. If no API key is provided, you'll be prompted to enter it when running the CLI.

Here are examples demonstrating how to use Plurality in a Next.js application using the App Router:

### Example 1: Weather API Route

This example shows how to create a simple weather API route using Plurality in a Next.js app:

```typescript
// app/api/weather/route.ts
import { NextRequest, NextResponse } from "next/server";
import { Swarm, Agent, AgentFunction } from "@pluralityai/agents";

// Initialize Swarm with your API key
const swarm = new Swarm("your-api-key-here");

// Define the get weather function
const getWeatherFunction: AgentFunction = {
  name: "getWeather",
  func: ({ location }) => {
    // In a real app, you would call a weather API here
    return JSON.stringify({ temp: 67, unit: "F" });
  },
  descriptor: {
    name: "getWeather",
    description: "Gets the weather for a given location",
    parameters: {
      location: {
        type: "string",
        required: true,
        description: "The location to get the weather for",
      },
    },
  },
};

// Create a Weather Agent
const weatherAgent = new Agent({
  name: "WeatherAgent",
  instructions:
    "You are a helpful weather agent. Use the getWeather function to provide weather information.",
  model: "gpt-4o",
  functions: [getWeatherFunction],
});

export async function POST(request: NextRequest) {
  const { query } = await request.json();
  const messages = [{ role: "user", content: query }];

try {
    const response = await swarm.run({
      agent: weatherAgent,
      messages,
    });
    const result = response.messages[response.messages.length - 1].content;
    return NextResponse.json({ result });
  } catch (error) {
    console.error("Error:", error);
    return NextResponse.json(
      { error: "An error occurred while processing your request." },
      { status: 500 }
    );
  }
}
```

### Example 2: Multi-language Chat API Route

This example demonstrates how to create a multi-language chat API route using Plurality in a Next.js app:

```typescript
// app/api/chat/route.ts
import { NextRequest, NextResponse } from "next/server";
import { Swarm, Agent, AgentFunction } from "@pluralityai/agents";

// Initialize Swarm with your API key
const swarm = new Swarm("your-api-key-here");

// Define the transfer to Spanish agent function
const transferToSpanishAgent: AgentFunction = {
  name: "transferToSpanishAgent",
  func: () => {
    console.log("Transferring to Spanish Agent");
    return spanishAgent;
  },
  descriptor: {
    name: "transferToSpanishAgent",
    description: "Transfer Spanish speaking users to the Spanish Agent",
    parameters: {},
  },
};

// Create an English Agent
const englishAgent = new Agent({
  name: "English Agent",
  instructions:
    "You only speak English. If a user speaks Spanish, use the transferToSpanishAgent function.",
  model: "gpt-4o",
  functions: [transferToSpanishAgent],
});

// Create a Spanish Agent
const spanishAgent = new Agent({
  name: "Spanish Agent",
  instructions: "Solo hablas español.",
  model: "gpt-4o",
});

export async function POST(request: NextRequest) {
  const { message } = await request.json();
  const messages = [{ role: "user", content: message }];

try {
    const response = await swarm.run({
      agent: englishAgent,
      messages,
    });
    const result = response.messages[response.messages.length - 1].content;
    return NextResponse.json({ result });
  } catch (error) {
    console.error("Error:", error);
    return NextResponse.json(
      { error: "An error occurred while processing your request." },
      { status: 500 }
    );
  }
}
```

These examples demonstrate:

1. How to initialize a `Swarm` instance with your API key.
2. Defining `AgentFunction`s for specific tasks (weather information and language transfer).
3. Creating `Agent`s with specific instructions and functions.
4. Implementing Next.js API routes that use the `Swarm` to process incoming messages.
5. Handling different scenarios: weather queries and multi-language support.
