Show HN: A 30-minute course to get up to speed on how AI agents work

2 points by ahd94 ↗ HN
9 short lessons, ~60 lines of Python. Each adds one concept — tool calling, memory, state, policy gates, self-scheduling — until you see the full agent stack.

The core loop is just a while loop. That's AgentExecutor. That's what the frameworks do.

Runs in the browser (Pyodide). No setup, no signup. Mock mode works instantly, or plug in a free Groq API key for live LLM responses.

I kept seeing engineers reach for LangChain or CrewAI without understanding what these frameworks actually do. Like they say, if you cannot build it, you do not understand it.
