queue-and-retry-safety

What problem does it solve?

Queues are at-least-once by design, which means duplicates and replays can lead to data corruption or duplicated work unless proper guardrails are enforced. This skill provides a systematic approach to enforce idempotency, DLQ governance, visibility timeout strategies, and correlation tracking for reliable queue processing.

Core Features & Use Cases

• Idempotency and guarded side effects: ensure repeated deliveries do not cause duplicate work or state changes.
• DLQ topology and alarms: consistent dead-letter handling with monitoring to catch poison messages early.
• Visibility timeout management: heartbeat long-running jobs and set appropriate base timeouts to minimize re-delivery.
• Payload validation and correlation propagation: verify payload shape and propagate correlation IDs through logs and downstream calls.

Quick Start

Configure idempotency checks, DLQ alarms, and visibility timeouts for your queue-based workers to ensure safe retries across SQS, EventBridge, and similar event-driven systems.
