Quick Start

import { Agent, OpenAIProvider } from '@ag-kit/agents';

const modelProvider = new OpenAIProvider({
  apiKey: process.env.OPENAI_API_KEY,
  defaultModel: 'gpt-4'
});

// Define a tool with parameters
const weatherTool = {
  name: 'get_weather',
  description: 'Get current weather for a location',
  schema: z.object({
    location: z.string().describe('City name or coordinates'),
    unit: z.enum(['celsius', 'fahrenheit']).default('celsius')
  }),
  handler: async (input: { location: string; unit: string }) => {
    // Tool implementation
    return { temperature: 22, condition: 'sunny', unit: input.unit };
  }
};

const agent = new Agent({
  name: 'my-agent',
  model: modelProvider,
  instructions: 'You are a helpful assistant with access to weather information.',
  tools: [weatherTool]
});

const result = await agent.run('What is the weather in New York?');
console.log(result.data);
