backend-async-messaging SKILL.md skillA
backend-async-messaging from bekaku/java-spring-boot-starter is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when adding or changing background work in this Spring Boot backend — @Async methods, RabbitMQ producers or consumers (@RabbitListener), queue topology, @Scheduled jobs, or anything that runs outside the HTTP request thread.
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
# Backend Async / Messaging — Playbook
> **Role:** HOW to add background work safely. Binding facts + evidence: `skills/backend/ASYNC_MESSAGING.md` (read it too).
> **Requires:** `backend-core`. **Often paired with:** `backend-data` (persistence in the job), `backend-testing`.
## Know this first
- Executor name is `ConstantData.ASYNC_TASK_NAME` (`"asyncExecutor"`) — not `asyncTaskExecutor`.
- There is **no** `@RabbitListener` in the codebase and `@EnableRabbit` is commented out. Adding the first consumer is a design change.
- Off the request thread there is no logged-in user, no audit user, and no caller transaction.
## Recipe A — run work asynchronously
1. Put the method on a Spring bean different from the caller (self-calls bypass the proxy):
```java
@Async(ConstantData.ASYNC_TASK_NAME)
public CompletableFuture<Void> rebuildIndex(Long actorId, Long targetId) { ... }
```
2. Pass `actorId` (and owner/target ids) explicitly. Do not call `AuthUtil#getAuthenticatedUser()` inside.
3. Do DB writes through a `@Transactional` service method called from the async method.
4. Log failures with context (no secrets); decide whether the caller needs the `CompletableFuture`.

How to install
mdr add bekaku/java-spring-boot-starter/backend-async-messaging@sha256:64f91bf74af16c41The line at the top of this page pins the label git:20260924.15dc64a, 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.
