I always thought that developing Agents would be the kind of thing that deters people—belonging to the realm of professional developers, where you might benefit indirectly but never get hands-on. Having looked at some tutorials and examples, my impression was that they all seemed complicated and unfamiliar.

It wasn't until I actually opened the Agent Builder documentation that my perception was completely overturned. When I saw the actual development interface and interaction flow, I realized how well thought out the tool is and how clear the logic is. From the organization of the documentation to the feedback during actual operation, every layer reduces the difficulty of getting started.

At that moment, I realized—good developer tools are like this. They turn your mindset from "This is too hard" to "Oh, I can give it a try."
