    Example session with this skill installed

    Fix the dual-write issue in my order-service. The database saves the order but sometimes the message-broker notification fails to send.

    • Read your context and instructions
    • Compiled the repair transactional outbox

    Analyzed order-service. Modified OrderRepository to include an OutboxRecord in the transaction. Created OutboxWorker to poll and dispatch messages with retry logic. Added crash-recovery tests.

    About this skill

    Repair systems that commit database changes but lose or duplicate the events that should follow.

    This skill traces transactions, event publication, retries, and consumers. It adds a transactional outbox, safe claiming, idempotent dispatch, cleanup, and crash-recovery tests.

    • Prevent committed changes without events
    • Stop duplicate publication
    • Recover after worker crashes
    • Verify database-to-broker delivery

    Ideal for SaaS, payments, orders, and event-driven services.

    • Requires a database that supports transactions. - Does not guarantee exactly-once delivery without consumer idempotency. - High-volume outboxes may require table partitioning.
