I make sketches on paper. Use case diagrams and state cycles and stuff. Really high-level. And then I type out user stories and then Gherkin scenarios.
And then I give the Gherkin to AI and have it code it and then I spend a week crawling through the code and straightening it out and torturing nostr:npub1wqfzz2p880wq0tumuae9lfwyhs8uz35xd0kr34zrvrwyh3kvrzuskcqsyn with code reviews because he's like Svelte AI. 😂
The end result, from the application logic, is very good, but the coding phase is a shitshow. Unless it's PHP. Only language I can just type out.
Most of the logic is already in the diagrams.
