What worries me about this is that the benefit of well practiced developers using AI to boost their productivity is there, but what happens to the new developers that piggyback off of LLM tooling too much and end up with worse understanding as a whole?

It sounds like it might be a good use case for testing documentation - verifying whether what documentation describes is actually in accordance with the code, and then you can act on it. With that in mind, it's also probably pointless to re-run if relevant code or documentation hasn't changed.

Re:Ask HN: What are you working on? (March 2025) on Monday March 31, 2025 @01:45AM (#43531519)

Did it also to learn rust, which made it easy to convert the engine code into webassembly and create a hand score calculator for the game :)! https://cerpins.com/mahjong-tool

Plans now are to finish the client, then freshen up the calculator with some QOL and visuals, surely a bug fix might be needed here and there as well.
