## AI overview

A lesson in an open-source course that explains how to build a bare-bones coding agent loop in Python. It covers decomposing goals into plans, executing them with tools, building a terminal user interface, and avoiding message-handling problems in the loop.

## Source excerpt

One agent loop, 9 tools, and a terminal you can steer.
