customerio-reference-architecture

Quick Review

This is a high-quality enterprise architecture skill for Customer.io integration. The description clearly indicates when to use it (architecture design, integration patterns, enterprise implementations), making it invocable by a CLI agent. The task knowledge is excellent, providing comprehensive TypeScript implementations for all major components: core service layer, event bus integration with Kafka, repository pattern, webhook handlers, and IaC with Terraform. The structure is clean with logical progression through 5 steps, though it could benefit from splitting large code blocks into referenced files for very large implementations. The novelty score is strong because implementing enterprise-grade Customer.io architecture with proper event-driven patterns, idempotency, observability, and multi-layer separation of concerns would require significant tokens and expertise from a CLI agent alone. This skill meaningfully reduces implementation complexity and ensures best practices. Minor deductions: the skill is quite long for a single file (could reference schemas/configs externally), and some advanced topics like retry logic, circuit breakers, and rate limiting could be more explicit.
