Background & analysis
On November 4, 2026, at 09:41, cnblogs.com published an article titled "Using an E-commerce Customer Service Chain to Explain LLM, RAG, Agent, and MCP". The article uses a real e-commerce customer service chain as its backbone to walk through four core AI technologies: LLM, RAG, Agent, and MCP. It presents a five-layer architecture design, explains the mathematical details behind cosine similarity, and provides production-grade, reusable Java code built with Spring AI. For practitioners, the article catalogs 16 pitfalls encountered during real-world implementation, covering issues such as retrieval bottlenecks, MCP exposure risks, and Agent looping failures. It also includes 13 quick-reference answers for interview preparation, tailored primarily for backend engineers transitioning into AI engineering or preparing for job interviews. As of now, only this single publication has been reported, with no subsequent updates.

How is heat calculated?About the methodHide
Heat counts how many independent sources covered a story in the last 48 hours: one source counts once no matter how many posts it published, decaying with a 24-hour half-life. What ranks first is what many people are talking about.
