    Repair Poison Message Loops

    Example session with this skill installed

    Our SQS consumer is stuck in a loop retrying one bad JSON message that fails validation. Help us add a DLQ and stop the infinite redelivery.

    • Read your context and instructions
    • Compiled the repair poison message

    Analyzed SQS consumer logic. Found missing 'MaxReceiveCount'.

    1. Updated Terraform to create a DLQ and set RedrivePolicy.
    2. Modified consumer to catch ValidationException and signal permanent failure.
    3. Added a recovery test to verify message quarantine after 3 attempts.

    About this skill

    Repair queue consumers where one bad message loops forever, blocks healthy traffic, or repeatedly crashes the same partition.

    This skill traces retries, ack/nack behavior, delivery counts, schema failures, DLQs, and replay. It adds bounded retry, poison classification, quarantine, safe replay gates, and recovery tests.

    • Stop infinite redelivery
    • Keep healthy messages moving
    • Preserve failure evidence
    • Replay only after repair

    Ideal for queues, workers, microservices, and event pipelines.

    • Does not resolve broad network outages or infrastructure-level downtime.
    • Requires access to consumer source code and broker configuration files.
    • Replay gates require manual operator triggers.

    What's inside

    Frequently Asked Questions

    It detects if redelivery counters survive restarts and adds durable tracking to ensure messages eventually move to a DLQ or quarantine.

    Yes. It prioritizes keeping the consumer running for healthy messages while isolating the specific record causing the head-of-line block.

    No. It is designed to add safe failure paths, DLQs, and quarantine logic rather than silently discarding data.
