You type "Create a PostgreSQL database in AWS" into Claude Code or Cursor, and it just works. But how? Most people think the AI does everything, but that's wrong. The AI can't touch your files or run commands on its own. This video breaks down the real architecture behind AI coding agents, explaining the three key players that make it all work: you (providing intent), the agent (the orchestrator), and the LLM (the reasoning brain). Understanding this matters if you're using these tools every day.
We'll walk through increasingly sophisticated architectures, from basic system prompts to the complete agent loop that enables real work. You'll learn how tools get executed, what context really means, how the agent manages the loop between you and the LLM, and why the LLM is stateless. We'll also cover practical considerations like MCP (Model Context Protocol) for integrating external tools and context limits that affect performance. By the end, you'll understand that the agent is actually the only "dumb" actor in the system—it's pure execution with no intelligence. The LLM provides the brains, you provide the intent, and the agent coordinates everything to make it happen.
