You need to realize when you’re being marketed to and filter out the nonsense.
Now I use agentic coding a lot with maybe 80-90% success rate.
I’m on greenfield projects (my startup) and maintaining strict Md files with architecture decisions and examples helps a lot.
I barely write code anymore, and mostly code review and maintain the documentation.
In existing codebases pre-ai I think it’s near impossible because I’ve never worked anywhere that maintained documentation. It was always a chore.
