There are few writeups but if you go to agentic coding meetups you can find people that show the stuff the build. It’s really quite impressive.

Do they go into the architecture and code structure, or more just the user-facing result? Coding agents do a lot of copy-paste or near equivalents and make way too much code to accomplish many things.

Ah, we don't have any such meetups where I am... Are these from people who can't program at all?

Also, yes. I wrote about this a bit here: https://lucumr.pocoo.org/2025/7/20/the-next-generation/

There are a lot of people who are entering programming via this thing.

Sure, but when I tried to vibe code something in a language I didn't have experience with, and so didn't look at the code at all, I had to basically trash the codebase after a few hundred lines because nothing I'd say could make the LLM fix the problems, or if it fixed them, more problems would pop up elsewhere.

In my experience, if you can't review the code and point out the LLM's mistakes to it, the codebase gets brittle fast. Maybe other people are better vibe coders than me, but I never managed to solve that problem, not even with Opus 4.1.
