Yep. It sucks. People are delusional. Let's ignore LLMs and carry on...

On a more serious note:

1) Split tasks into smaller tasks just like a human would do

Would you bash your keyboard for an hour, adding all video controls at once before even testing if anything works at all? Ofc not. You would start by adding a slider and test it until you are satisfied. Then move to next video control. An so on. LLMs are the same. Sometimes they can one-shot many related changes in a single prompt but the common reality is what you experienced: it works sometimes but the code is suboptimal.

2) Document desireable and undesireable coding patterns in AGENTS.md (or CLAUDE.md)

If you found over usage of useEffect, document it on AGENTS.md so next time the LLM knows your preference.

I have been using LLMs since Sonet 3.5 for large enterprise projects (1kk+ lines of code, 1k+ database tables). I just don't ask it to "draw the rest of owl" as the saying goes.
