Designing a parser and deciding how to solve the problem isn't work? Writing code is not the only work involved in building something.
I love writing code and avoid using an LLM for pleasure projects, but c'mon, this kind of derisiveness is getting old and tiring.
parsers are easy... provided you know exactly what you're trying to parse. Knowing what to parse and how to parse it is the vast majority of the work. And playtesting is also not "making this". It's "this didn't work... please do the work for me again"
