# Spring Boot — Kafka messaging
Apply Spring 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 Spring Boot
- Review Spring Kafka consumers/producers
- Improve retries, dead-letter topics, or idempotency in Spring Kafka
+ - Configure Spring Kafka topics serializers or listener containers
+ - Add Spring Kafka dead-letter topic handling
## Workflow
1. **Read reference and assess project context**
Read `references/314-frameworks-spring-kafka.md` and inspect current messaging setup before proposing changes.
2. **Gather scope and decide target improvements**
Identify reliability and throughput goals and define the minimum safe set of changes.
3. **Apply framework-aligned changes**
Implement/refactor Spring Kafka configuration, producer/consumer logic, and failure handling.
4. **Run verification and report results**
Execute build/tests and summarize what changed, what was verified, and follow-up actions.
