Let's talk about the latest trend in AI and that's harness engineering. Harness engineering is a system that allows engineers and developers to build reliable AI agent systems so they're consistent and they always perform their role in the world task. And that's harness engineering. You can see in this chart right here that they have a lot of the agent first engineering principles, such as, you know, enforcing knowledge in the repo, enforcing architecture, and then of course using strict boundary. Harness engineering into essentially five kind of layers. You have the tools, which is the databases that it interacts with, the APIs, MCs, all that stuff. Then you have the guardrails, which is super important because that's how you enforce the rules of the agents and whether or not they have access to certain things or whether or not they can do a specific action. All that comes from the guardrails. Then you have memory and state, which is very important because when you have a tool like this, you want to make sure that it attracts conversation history. It understands, uh, long-term context and understands the patterns of whatever it's building. Then you have verification loops, and you can see this right here in the autonomy loop section of the chart. But essentially, it's auto-checking its outputs, making certain that before it puts it into production, that it does unit tests, or before it actually finalizes it. Then you have error recovery, which I had to do a little bit of research on because it really comes down to how harness engineering, because this is essentially what happens when they adjust their strategies after something doesn't work. So it's something, you know, as far as, how they recover from an error or a message that didn't work. But that is harness engineering. Remember, this has been mastering machines, where we discover tomorrow's reality.
