+
+The create_agent method of agents/base.py has a large number of parameters. I want
+to offer an easier way to create agents without having to enter in
+so many parameters or even offer built-in features quicker (confirmations, human-as-a-tool).
+
+I want to get comments on 2 different possible solutions.
+
+First is the builder pattern which is not as common in Python but still used.
+
+Second is config pattern which is a more common pattern.
