    Repair Out-of-Order Event Bugs

    Example session with this skill installed

    My Stripe webhooks are arriving out of order and occasionally overwriting the 'paid' status with 'pending' from an older event. Please fix the handler in services/payments.ts.

    • Read your context and instructions
    • Compiled the repair out-of-order event

    I've analyzed services/payments.ts and added a last_event_version check. I modified the database schema to store this version and updated the handler to reject stale events. I also added a test suite to simulate out-of-order delivery.

    About this skill

    Repair systems where delayed or out-of-order events overwrite newer data or move workflows backward.

    This skill traces webhooks, queues, and event streams, then adds version checks, monotonic state guards, safe buffering, reconciliation, and deterministic tests.

    • Reject stale events
    • Preserve valid transitions
    • Handle duplicates and sequence gaps
    • Verify reordered delivery

    Ideal for SaaS, payments, logistics, and event-driven apps.

    • Cannot fix missing data if the provider does not send sequence or version info.
    • Limited effectiveness on global ordering if no aggregate ID is present.
