5 postsComplete Guide to AI Agent Architecture Patterns: From Three Pillars to Multi-Agent Systematic Navigation
AI Agent is not a single technology -- it is an entire architecture system. This article is a systematic navigation: starting from the Agent Three Pillars (Context/Cognition/Action), through the three-stage evolution of AI engineering (Prompt -> Context -> Harness), to eight Multi-Agent design patterns and production-grade Harness infrastructure. Each topic links to a dedicated deep-dive article.
Modular RAG Pipeline: Designing RAG as a Composable DAG
RAG doesn't have to be a rigid three-step process. It's a set of steps that can be dynamically enabled, skipped, or reordered. Pipeline as Code lets the system adapt its behavior without redeployment.
Three Generations of RAG: From Naive to Modular
Naive RAG works but has real problems. Advanced RAG patches those problems. Modular RAG rearchitects the whole system to be composable and configurable. Understanding all three generations is the key to understanding why modern RAG systems look the way they do.
RAG vs Fine-tuning: It's Not Either/Or
RAG and Fine-tuning solve different problems. RAG gives the model new knowledge; Fine-tuning changes the model's behavior and style. In most cases you use both, not pick one.
