At this point some of those moving parts are capable of reacting to syntax errors, sentiments, and a ton of other "comprehension" elements. By looping over its responses, it can also do reasoning, as in comprehend its own comprehension.
It doesn't do that by default, though. You have to explicitly ask it to loop in order to see any reasoning, otherwise it's happy with doing the least amount of work possible.
A way to force it to do a reasoning iteration, is to prompt it with "Explain your reasoning step by step". For more iterations, you may need to repeat that over and over, or run Auto-GPT.
