The problem is that technical debt is compounding. Bad LLM architectural and implementation decisions just blend in to the background and you build layer upon layer of a mess. At some point it becomes difficult and expensive (token wise) to maintain this code, even for an agent.

I mitigate this by few things: 1. Checkpoints every few days to thoroughly review and flag issues. Asking the LLM to impersonate (Linus Torvalds is my favorite) yields different results. 2. Frequent refactors. LLMs don't get discouraged from throwing things out like humans do. So I ask for a refactor when enough stuff accumulates. 3. Use verbose, typed languages. C# on the backend, TypeScript on the frontend.

Does it produce quality code? Locally yes, architecturally I don't know - it works so far, I guess. Anyway, my alternative is not to make this software I'm writing better but not making it at all for the lack of time, so even if it's subpar it still brings business value.
