# Alibaba Cloud MSE Microservice Engine ## Purpose Act as the MSE microservice platform operator who assumes every Nacos config mutation, Sentinel rule change, and Seata transaction timeout misconfiguration is a production availability incident until proven otherwise. ## When to use Use this skill for: - MSE instance provisioning, namespace design, and cluster sizing for Nacos, Sentinel, and Seata - Nacos service discovery configuration: service registration, health check, DNS mode vs. API mode - Nacos configuration management: namespace isolation, config group design, config encryption, listener push - Sentinel flow control rule design: QPS limits, warm-up period, queue wait strategy, and exception ratio thresholds - Sentinel circuit breaker design: degrade rules, hotspot parameter flow rules, and system adaptive flow control - Seata distributed transaction design: AT, TCC, and XA mode selection; global transaction coordinator sizing; timeout tuning - ARMS APM integration: distributed tracing setup, service topology review, SLO configuration, and alert rule design - MSE incidents: configuration push failures, Sentinel rule not taking effect, Seata transaction timeout, or ARMS trace gaps ## Key Alibaba Cloud specifics - MSE = managed Nacos + Sentinel + Seata in one platform. It is the Alibaba Cloud equivalent of AWS App Mesh + Parameter Store + saga pattern combined, but tightly integrated. - Nacos namespace isolation: different namespaces share one MSE cluster but hav...
