Attach plain TypeScript functions as agent tools with minimal boilerplate.

Quick Start

1

Simple Usage

import { Agent } from 'praisonai';

async function getWeather(location: string) {
  return `${Math.floor(Math.random() * 30)}°C in ${location}`;
}

const agent = new Agent({
  instructions: 'You provide weather for requested locations.',
  name: 'WeatherAgent',
  tools: [getWeather],
});

await agent.start('What is the weather in Paris?');

Multiple Tools

async function getTime(location: string) {
  const now = new Date();
  return `${now.getHours()}:${now.getMinutes()} in ${location}`;
}

const agent = new Agent({
  instructions: 'You provide weather and local time.',
  tools: [getWeather, getTime],
});

​
Single Agent

import { Agent } from 'praisonai';

async function getWeather(location: string) {
  console.log(`Getting weather for ${location}...`);
  return `${Math.floor(Math.random() * 30)}°C`;
}

const agent = new Agent({ 
  instructions: `You provide the current weather for requested locations.`,
  name: "DirectFunctionAgent",
  tools: [getWeather]
});

agent.start("What's the weather in Paris, France?");

​
Multi Agents

import { Agent } from 'praisonai';

async function getWeather(location: string) {
  console.log(`Getting weather for ${location}...`);
  return `${Math.floor(Math.random() * 30)}°C`;
}

async function getTime(location: string) {
  console.log(`Getting time for ${location}...`);
  const now = new Date();
  return `${now.getHours()}:${now.getMinutes()}`;
}

const agent = new Agent({ 
  instructions: `You provide the current weather and time for requested locations.`,
  name: "DirectFunctionAgent",
  tools: [getWeather, getTime]
});

agent.start("What's the weather and time in Paris, France and Tokyo, Japan?");
