Harnesses are like game engines because you are giving senses to the LLM.

It just so happens that the “world” is (at the moment) a computer.

The “loop” is akin the rendering loop. It determines the “turns” anything can take. It is the state machine. The loop doesn’t “act” per se, actions must happen in the background, must be async, and generally non-cyclical. These are your graphs. They must not overtake the processing of the rendering loop / state machine.
