mq-reliability SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
mq-reliability from baixuanzhu/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add baixuanzhu/skills/mq-reliability@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

RabbitMQ / 消息队列可靠性契约：在写生产者或消费者前用五个入口问题定下可靠性级别、 幂等策略、重试与死信、顺序保障、积压预案，避免测试全绿但线上丢消息、重复执行、 积压失控的假绿陷阱。 在使用 RabbitMQ / Spring AMQP 写消息生产者或消费者、设计异步事件分发、 排查消息丢失 / 重复消费 / 积压 / 死信时使用。 触发信号：@RabbitListener、RabbitTemplate、spring-boot-starter-amqp、 AmqpTemplate、消息队列、MQ、消费者、生产者、事件分发、异步通知、 丢消息、消息丢失、重复消费、死信队列、DLQ、消息积压、顺序消费、幂等。 不适用：RabbitMQ 安装部署 / 集群运维、Kafka / RocketMQ 等其他 MQ 的 API 用法、 Spring Cloud Stream、消息中间件选型。.
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
# MQ 可靠性契约 模型对 RabbitMQ 基础配置（DLX / 重试 / durable）的判断已经够准（基线实测 3/3 全对），不必再写。 真正的缺口在**测试全绿但线上出事**的地方：DLQ 配了没人看、幂等不稳、积压无监控。 本技能只做三件事：把五个决策定下来、动手前读一遍、写完验证。 ## 两条原则 1. **五问先答，契约落盘。** 第一次在项目里写消息代码时，把 D1–D5 的答案写进 `.claude/rules/mq-reliability.md`（提案-同意制，未经同意不写）；之后每次动生产者/消费者前先读它。 读不到时按 `references/01-decisions.md` 的默认值写，并在回复里声明 「按 mq-reliability 默认，未读到项目契约」。 2. **写完用假绿元判据自查。** 测试环境不杀 broker、只投一次、消息量小—— 把 broker 停掉 / 同条消息投两次 / 投 10 万条，你的代码会出什么问题？ 想不出来就是还没想清楚，回 `references/02-traps.md` 逐组过。 ## 第一步：读项目 | 读什么 | 得到什么 | |---|---| | `pom.xml` / `build.gradle` | 是否已有 spring-amqp / spring-rabbit 依赖 | | `.claude/rules/mq-reliability.md` | 项目已有的五问答案。**读到才生效**，读到就遵守 | | 既有 `@RabbitListener` / `RabbitTemplate` | 既有惯例：ack 模式、幂等做法、拓扑风格 | **项目惯例与下表默认冲突时，惯例优先。** ## 入口五问 写生产者或消费者前，五问都要有答案。漏一问就漏一个决策维度。 | # | 入口问题 | 决策什么 | 不答的后果 | |---|---|---|---| | D1 | 这条消息丢了会怎样？ | 可靠性级别：confirm + 持久化 + ack 策略 | 静默丢消息 | | D2 | 同一条消息处理两次会怎样？ | 幂等策略：去重键 + 去重位置 | 重复扣款 / 重复通知 | | D3 | 消费失败了消息去哪？ | 重试次数 + DLX + **DLQ 谁来看** | 毒消息死循环 / 死信黑洞 | | D4 | 这些消息必须按顺序吗？ | 单消费者 / 业务键分片 + SAC | 状态错乱 | | D5 | 生产快过消费怎么办？ | prefetch + 积压告警阈值 + 降级 | 积压无人知 | 展开见 `references/01-decisions.md`。 ## 强约束 …

How to install
mdr add baixuanzhu/skills/mq-reliability@sha256:6e603014344b008dThe line at the top of this page pins the label v1.0.0, 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.
