For me, the post is missing an explanation of the reason why I would want to build my own coding agent instead of just using one of the publicly available ones.
Knowing how to build your own agent and what that loop is going to be the new whiteboard coding question in a couple of years. Absolute. It's going to be the same as "Reverse this string", "I've got a linked list, can you reverse it?", or "Here's my graph, can you traverse it?"
I see, thanks. I was wondering earlier if there would be any practical advantage in creating a custom agent, but couldn't think of any. I guess I simply misunderstood the purpose of your post.
