You chosen AI agent can and will plan as far ahead as you tell it to plan. If you tell it to do things in iteration 1 that might block it in iteration 3 then you should have told it more about where you want to go back in iteration 1.

At some point I have to describe what I need with such a level of detail and precision, that if I had chosen to wrote it in my language of interest I'd have had the code I wanted long before i finish writing all the boundry conditions, safe guards, long term pitfalls etc. Thats if the system even respects all of those things, it might just lose track of some instruction at some point or make some bs placeholder and now we're back to bug hunting, only i'm now wading through code that is best described as slop.
