Agents & Harnesses, Demystified
Finally understand what people mean by "AI agents" and "harnesses," in plain language — so the most hyped words in tech stop sounding like magic, and you can judge for yourself when to trust one.
"Agent" is the word of the moment — in headlines, sales decks, and your group chats. Most people nod along without a real picture of what it means, which is its own quiet kind of "behind." It's refreshingly un-magical, and once you see it, you'll spot agents everywhere and hold a grounded opinion about what they can and can't be trusted to do.

- The fear it addresses
- What an agent actually is
- So what's a "harness"?
- The spectrum: chatbot → assistant → agent
- The real question: how much do you let it act?
- Lab 10: See the loop for yourself
- Common mistakes
- You can now…
Explain what an agent and a harness are without hand-waving, place any AI product on the chatbot-to-agent spectrum, and decide — deliberately — how much freedom to give one based on what it costs to be wrong.
