Introduction

Deck, formerly Prompt Deck, provides AI prompt management for Laravel and PHP.

Organise your AI agent instructions as versioned files, compare prompt performance, and activate the right version across your app with variable interpolation, tracking, A/B testing, and Laravel AI SDK integration.

Important

Prompt Deck is now Deck by PromptPHP.

From v0.4.0, the package moved from veeqtoh/prompt-deck to promptphp/deck, and the namespace changed from Veeqtoh\PromptDeck to PromptPHP\Deck.

Upgrading from v0.3.x? See the upgrade guide.

Quick Start

Installation

composer require promptphp/deck

Publish the config and migrations

php artisan vendor:publish --provider="PromptPHP\Deck\Providers\DeckServiceProvider"

# Run migrations.
php artisan migrate

Creating a Prompt

Use the Artisan command to create a versioned prompt

php artisan make:prompt order-summary

This creates the following structure

resources/prompts/
└── order-summary/
    ├── v1/
    │   └── system.md
    └── metadata.json

Edit resources/prompts/order-summary/v1/system.md with your prompt content. Use {{ $variable }} syntax for dynamic values:

You are a {{ $tone }} customer service agent.
Summarise the following order for the customer: {{ $order }}.

Using a Prompt

Load and render prompts with the Deck facade

use PromptPHP\Deck\Facades\Deck;

// Load the active version of a prompt.
$prompt = Deck::get('order-summary');

// Render a role with variables.
$prompt->system(['tone' => 'friendly', 'order' => $orderDetails]);
// "You are a friendly customer service agent. Summarise the following order..."

// Build a messages array ready for any chat-completion API.
$messages = $prompt->toMessages(['tone' => 'friendly', 'order' => $orderDetails]);
// [['role' => 'system', 'content' => '...']]

Versioning

Create a new version of an existing prompt

php artisan make:prompt order-summary
# Automatically creates v2, v3, etc.

Activate a specific version

php artisan prompt:activate order-summary v2

# or

php artisan prompt:activate order-summary 2

Or load a specific version programmatically

$prompt = Deck::get('order-summary', 'v2');

Laravel AI SDK Integration

If you use the Laravel AI SDK, add the HasPromptTemplate trait to your agents. This way, you do not need to define the instructions() method as it is provided automatically.

use PromptPHP\Deck\Concerns\HasPromptTemplate;

class OrderAgent extends Agent
{
    use HasPromptTemplate;

    // instructions() and promptMessages() are provided automatically.
}

Running make:agent will also auto-scaffold a matching prompt directory.
