alt Hacker NewsI experimented with vibe coding (not looking at the code myself) and it produced around 10k LOC even after refactors etc.
I rewrote the same program using my own brain and just using ChatGPT as google and autocomplete (my normal workflow), I produced the same thing in 1500 LOC.
The effort difference was not that significant either tbh although my hand coded approach probably benefited from designing the vibe coded one so I had already though of what I wanted to build.
Sounds like a great oppurtunity to understand your own development process, and codify it in such detail that the agent can replicate how you work and end up with less code but doing the same.
My experience was the same as you when I started using agents for development about a year ago. Every time I noticed it did something less-than-optimal or just "not up to my standards", I'd hash out exactly what those things meant for me, added it to my reusable AGENTS.md and the code the agent outputs today is fairly close to what I "naturally" write.
