Okay, let's recap what we learned so far. We talked about how tools are such a key part of agents because they are what allow you to connect your agents to the external world. So you're going to build tools and use existing tools to call APIs, to integrate with your internal systems, to do some computational. to integrate with your internal systems, to do some computational. It's a translation layer that allows your agents to communicate with existing programs that you might have. But in order for these tools to work properly, you need to make sure they're versatile, you need to make sure they're fault tolerant, and need to make sure that they have a caching strategy. If you make sure that you're using those three qualities on all the tools that you use, you then have a system that is more reliable. So make sure to watch out for that when you're choosing what tools you're gonna use or building your own tools. Keep in mind again, that because we're using Query AI, you can not only use the tools that Query AI offers itself, but you can also use all the tools that a link chain offers. So you have a huge range of tools that you can start with. All right, we're going to wrap this lesson here. You're doing amazing. Keep at it. You're going to love our next lesson because you're going to talk about even more interesting stuff that is going to unlock more use cases. So I see you on your next lesson.
