Does this skill follow modern PHP standards?

Yes, it specifically targets PHP 8.4, utilizing features like readonly classes and constructor promotion for clean, modern architecture.

What happens if the message broker is offline?

The OutboxProcessor will attempt to publish messages based on a retry limit with exponential backoff; if it fails repeatedly, the message is moved to a dead-letter repository for manual intervention.

Is this compatible with Symfony and Doctrine?

Yes, the skill provides specific infrastructure implementations for Doctrine ORM and Symfony-compatible console commands for background processing.

What is the Transactional Outbox pattern used for?

It is used to ensure that a message is reliably sent to a broker (like RabbitMQ or Kafka) only if the local database transaction succeeds, preventing data inconsistency.

API Development

Implements a robust Transactional Outbox infrastructure for PHP 8.4 to ensure reliable event publishing and data consistency.

This skill automates the creation of a comprehensive Transactional Outbox pattern, a critical requirement for maintaining consistency in distributed systems and microservices. It generates all necessary components—including immutable domain entities, repository interfaces, processing logic, and CLI commands—to ensure that messages are only dispatched to a broker after a successful database transaction. By providing built-in retry mechanisms, exponential backoff, and dead-letter queue support, it eliminates the risk of message loss during broker outages and simplifies the implementation of reliable event-driven architectures.

Key Features

01Produces Infrastructure implementations for Doctrine ORM and Symfony Console commands.

02Includes automated database migrations for structured message storage.

03Creates Application layer processors with configurable retry and dead-letter logic.

04Generates ready-to-use unit tests for both Domain and Application layers.

05Generates PHP 8.4 immutable OutboxMessage entities and Domain layer interfaces.
