The Technical Architecture of Agentic AI & Multi-Agent Systems

A working guide to the design patterns, communication protocols, orchestration frameworks, memory architectures, guardrails, evaluation, context window management, and production failure modes that matter when shipping agentic systems in 2026.

The 7 agentic design patterns, MCP and A2A protocols, a framework comparison across LangGraph, CrewAI, and AutoGen, memory architecture choices, multi-agent topologies, and the production failure modes that cost teams the most debugging time.
