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.
