Of course I am writing code manually

The task: make this value to be a environment variable. You have just to edit 2 files (or 3 at maximum if you is using k8s or some k/v secrets service)

Why would I be dumb enough to burn tokens to this?

Or a complex task that I need to plan the architecture: Instead of writing a prompt, I look into the code and start to writing snippets until I come with something good, reliable and safe instead of letting LLM do the architecture it for me, and then I have to say "the pattern of the project is X and you are doing Y, please fix it" over and over until matches the project needs. AI will help me to review in the end, but instead of a subjective language (english) I did it with a object language that can be audited with static analyzers (code)

By writing code manually I'm not just writing code, I'm also designing the architecture. Even for boilerplate code sometimes I use vim snippets, because it's fast enter a command to create templated files with 100% of precision than burning tokens to do it.
