Use when you need Kafka messaging in Quarkus with SmallRye Reactive Messaging — including channel/topic design, build-time Jackson serialization, typed @Channel/@Incoming, ack/failure strategies, retries/DLQ, idempotency, Dev Services, and Testcontainers integration tests. This should trigger for requests such as Add Kafka in Quarkus; Review Reactive Messaging consumers; Improve failure handling for Quarkus Kafka; Configure Quarkus Reactive Messaging Kafka channels; Add Quarkus Kafka failure str

Prompt

We need to ingest JSON payloads on Quarkus Kafka channel `inventory-updates` using a custom deserializer `com.example.InventoryDeserializer`. Standard practice might be to modify code directly, but outline the workflow and configuration.

Quarkus — Kafka messaging

Apply Quarkus Kafka guidance with concrete examples for design, implementation, and error handling.

Constraints

Compile before messaging refactors; verify after changes.

MANDATORY: Run ./mvnw compile or mvn compile before applying any change
SAFETY: If compilation fails, stop immediately
VERIFY: Run ./mvnw clean verify or mvn clean verify after applying improvements
BEFORE APPLYING: Read the reference for detailed rules and examples

When to use this skill

Add Kafka in Quarkus
Review Quarkus Reactive Messaging consumers/producers
Improve retries, dead-letter handling, or idempotency in Quarkus Kafka
Configure Quarkus Reactive Messaging Kafka channels
Add Quarkus Kafka failure strategy or DLQ handling

Workflow

Read reference and assess project context

Read references/414-frameworks-quarkus-kafka.md and inspect current messaging setup before proposing changes.

Gather scope and decide target improvements

Identify delivery semantics and resilience goals to define safe improvements.

Apply framework-aligned changes

Implement/refactor channels, serializers, and failure strategies in Reactive Messaging.

Run verification and report results

Execute build/tests and summarize what changed, what was verified, and follow-up actions.
