How do you design your classes?

Do you follow a method when you create a class?

Do you think its role should be obvious right away — even in the code, beyond just the class name?

And do you believe a language or framework could actually help with that?

Personally, I kept running into the same problems:

• A class that was supposed to be “business logic” ends up mixing in low-level concerns
• Layers get blurry
• New devs ask: “What does this class even do?”

So I tried something. I made a tiny language where the role of a class is the first thing you write:

@Agent
public class OrderService {

    @With_compat
    private OrderRepository repo;

    public void checkout(Order o) {
        repo.save(o);
    }
}
