About symfony:symfony-messenger

A Symfony skill for implementing asynchronous workflows with Messenger, Scheduler, or Cache and improving retry and failure handling. It guides delivery semantics, idempotent handlers, routing, and validation of replay scenarios.

Key features

  1. 01Define asynchronous delivery semantics
  2. 02Design idempotent handlers and routing
  3. 03Configure retries and failure transports
  4. 04Validate success and failure replay

Use cases

  1. 01Implementing asynchronous Symfony workflows
  2. 02Stabilizing retry and failed-message handling

Install

Details

From the project README

Symfony Messenger (Symfony)

Use when

  • Implementing asynchronous workflows with Messenger/Scheduler/Cache.
  • Stabilizing retries and failure transports.

Default workflow

  1. Define async contract and delivery semantics.
  2. Implement idempotent handlers and routing strategy.
  3. Configure retries, failure transport, and observability.
  4. Validate success/failure replay scenarios.

Guardrails

  • Assume at-least-once delivery, not exactly-once.
  • Keep handlers deterministic and side-effect aware.
  • Surface poison-message handling strategy.

Progressive disclosure

  • Use this file for execution posture and risk controls.
  • Open references when deep implementation details are needed.

Output contract

  • Async config/handlers updated.
  • Retry/failure policy decisions.
  • Operational validation evidence.
