Demystifying AI Agents: Building an Agentic Pipeline From Scratch in Pure Python

Most AI demos look impressive until you ask a simple question: What is actually happening under the hood? Frameworks like LangChain, CrewAI, and Microsoft AutoGen make it incredibly easy to spin up an “AI agent” in a few lines of code. But abstractions come with a cost. Many developers can build agents using frameworks without fully understanding the runtime architecture powering them. At their core, most agent frameworks are built around surprisingly simple primitives: Prompt orchestratio...
