NATS skill helps you design reliable, cloud-native messaging patterns so distributed services can communicate quickly without manual integration work.
Use case: You are building an order-processing microservice system where multiple workers handle orders.process, while a validator service answers orders.validate requests with strict timeouts and optional durable replay via JetStream.
Use the NATS skill to draft a minimal publish/subscribe and request/reply example for your service and include the correct subject wildcards and timeouts for localhost deployment.

To design request/reply messaging, use NATS core semantics to pair requests with replies and apply deterministic timeouts. This ensures strict response deadlines for services like an order validator answering requests without indefinite blocking.
Routing pub/sub messages with subject wildcards enables targeted delivery across distributed services. NATS uses dot-separated subjects with single and multi-level wildcards, allowing subscribers to filter and receive only the specific event categories they need.
Configuring JetStream persistence involves adding durable streams and consumers to your messaging flow. This provides at-least-once delivery guarantees, operational control, and message replay capabilities for microservices requiring reliable event processing.
Yes, queue groups enable load balancing across multiple worker instances. NATS queue-group semantics distribute messages among competing workers subscribed to the same subject, enabling scalable microservice processing for tasks like order handling.
NATS supports durable replay for distributed microservices through JetStream. By configuring durable streams and consumers, services can replay missed messages, providing operational control and ensuring data persistence across system restarts.
Microservices fail to receive messages with subject wildcards when subject patterns mismatch the published dot-separated structure. Verify that single and multi-level wildcards align correctly with your publish subjects to ensure proper targeted delivery.
