Use when implementing Kafka, RabbitMQ, Pulsar, or JMS producers and consumers in Spring Boot 3. Covers event contracts, idempotency, retries, dead-letter handling, ordering, and outbox delivery.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Event-Driven Messaging Design for at-least-once delivery unless the complete system proves stronger semantics. ## Event contract - Use an immutable event envelope with `eventId`, `eventType`, `occurredAt`, `schemaVersion`, and payload. - Treat published schemas as APIs. Add fields compatibly and never silently change meaning. - Put correlation and causation IDs in headers or the envelope. - Do not publish JPA entities or framework-specific serialization shapes. ## Producer rules - Publish only after the originating state change is durable. - Use a transactional outbox when database state and broker publication must agree. - Use deterministic partition keys when per-aggregate ordering matters. - Configure delivery timeout and acknowledgements explicitly. ## Consumer rules - Make handlers idempotent with a durable processed-event record or naturally idempotent write. - Keep the transaction boundary around the state change and idempotency marker. - Classify transient and permanent failures before configuring retries. - Bound retries with backoff, then route poison messages to a dead-letter destination. …

How to install
mdr add rrezartprebreza/spring-boot-skills/event-driven-messaging@sha256:db57748c4497beb3The line at the top of this page pins the label git:20260810.7551dc9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
