From Chatty LLM Agents to Governable Systems: An Architectural Guide

This article provides a comprehensive guide to LLM agents and multi-agent systems, covering strategies from ReAct to graphs, durable execution, sandboxing, memory, evals, and security in production. It helps developers understand when a single agent suffices, when multiple agents are beneficial, and how to choose minimal viable architectures. The guide emphasizes that modern agent systems are multi-layered stacks rather than single libraries.
