Micronaut — Kafka messaging

Apply Micronaut 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 Micronaut
• Review Micronaut Kafka consumers/producers
• Improve retries, dead-letter handling, or idempotency in Micronaut Kafka
• Configure Micronaut Kafka clients listeners or SerDes
• Add Micronaut Kafka retry or dead-letter handling

Workflow

1. Read reference and assess project context

Read references/514-frameworks-micronaut-kafka.md and inspect current messaging setup before proposing changes.

2. Gather scope and decide target improvements

Identify delivery guarantees and resilience requirements to define safe improvements.

3. Apply framework-aligned changes

Implement/refactor clients, listeners, and failure strategies in Micronaut Kafka.

4. Run verification and report results

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