Ask HN: Has anyone properly set up LLM programming workflow?

With new LLMs being released almost daily at this point and with availability of all the possible "spec-driven" workflows(BMAD, AgentOS etc), is anyone really developing production ready software with little to no intervention? I have talked to a lot of software developers in my circles and most of them are using LLMs for autocomplete(which has gotten extremely good with Augment code and others) or attempting to "one-shot" some small features. I keep reading that many people are writing 10k lines of code daily which quite honestly sounds plausible. What I don't understand is whether that code is maintainable, modular, performant and otherwise production ready. I believe that with proper specs and setup, modern LLMs can do all that, but I have yet to hear real life examples of that.
