The key to using LLMs effectively is to make sure you already have a solid understanding of what you are aiming to buildbefore you start. You always have to be explicit regarding what you want done at a structural level. The more scaffolding youprovide up front the less room the agent has to go outside your design. A corollary to this observation is that you do haveto understand the domain to make effective use of LLMs. If you are not equipped to evaluate whether the code it producedsolves the problem in a correct way, then you basically end up at a casino pulling a lever on a slot machine and hoping fora decent solution to fall out. LLMs are good at filling in the gaps and doing boilerplate, but you still have to do design andarchitecture the same way you always did.
