​
Installation

You can install LarAgent via Composer: 
composer require maestroerror/laragent
After installing the package, publish the configuration file: 
php artisan vendor:publish --tag="laragent-config"
This will create a config/laragent.php file in your application.

​
Configuration

​
OpenAi

If you are using OpenAI API, just set your API key in your .env file and you are good to go: 
OPENAI_API_KEY=your-openai-api-key

​
Basic Configuration

The published configuration file contains the following default settings: 
// config for Maestroerror/LarAgent
return [
    'default_driver' => \LarAgent\Drivers\OpenAi\OpenAiCompatible::class,
    'default_chat_history' => \LarAgent\History\InMemoryChatHistory::class,

    'namespaces' => [

    'default_context_window' => 15000,
    'default_max_completion_tokens' => 100,
    'default_temperature' => 0.7,
    // Enable/disable parallel tool calls
    'parallel_tool_calls' => true,
    // Store metadata with messages
    'store_meta' => true,
    // Save chat keys to memory via chatHistory
    'save_chat_keys' => true,
],

​
Creating Your First Agent

​
Using Artisan Command

The quickest way to create a new agent is using the provided Artisan command: 
php artisan make:agent WeatherAgent
This will create a new agent class in the App\AiAgents directory with all the necessary boilerplate code.

​
Basic Usage

​
Simple Response

use App\AiAgents\WeatherAgent;

// Create an instance for a specific user or chat session
$agent = WeatherAgent::for('user-123');

// Get a response
$response = $agent->respond('What\'s the weather like in Boston?');

echo $response; // "The weather in Boston is currently..."

​
Adding Tools

Tools allow your agent to perform actions and access external data: 
namespace App\AiAgents;

use LarAgent\Agent;
use LarAgent\Attributes\Tool;

class WeatherAgent extends Agent
{
    // ... other properties

    #[Tool('Get the current weather in a given location')]
    public function getCurrentWeather($location, $unit = 'celsius')
    {
        // Call a weather API or service
        return "The weather in {$location} is 22 degrees {$unit}.";
    }
}
