Prompt

I'm testing out the capacity of this new model, which is the Opus 5 model. One of the best ways to test this is through one unique prompt which is going to be this prompt I want to see what you are capable of doing. I want to see the level of excellence, the attention to detail, the thought, the perception, the truth towards what the task we provide. I want you to create a Minecraft clone. An identical Minecraft clone that will be able to run on the browser. And the idea is that I will be able to run in the browser as if I were to launch Minecraft and then I'll have the option of single player, of multiplayer, of choosing the difficulty. For multiplayer we don't actually need to set anything up. So it's just a stub. But for single player we should be able to go in creative mode, create our world and then play the world. And every single detail needs to be coherent from first principles from this. So understanding this, what does everything else mean? Because in building Minecraft, well if we open it up on the browser, obviously it's going to be just localhost. We're not sharing this with anyone, it's just to test the capacity. In doing so we will be able to open it up on the browser and we want it to be as if we were to launch just the Minecraft. And we were to have arrived on the screen of Minecraft. So what does that mean? Well it means the UI. the UX. The way the fonts are. The images. The sound. Everything needs to be exactly the same as Minecraft and the attention to detail is required at every single nuance. Because once we enter the game in single player in which our test and the world is going to be generated and its loaded and once its loaded then it enters and then once its entered then I can do what I wanna do I wanna be able to enjoy it I want to be able to obviously not just build things but survive and enjoy Minecraft so what does that mean? I'm not gonna tell you what exactly I want and what I don't want because the only thing I mentioned is multiplayer doesn't need to work because that's a complexity of its own but the rest fundamentally is the engine behind it all and should be able to be done. I do not want you to rush and there is actually no need to rush. It's about understanding, it's about truth, it's about awareness, it's about questioning the status quo, it's about understanding the first principles. You can create tasks, to-dos, run things in parallel, sub-agents, whatever you want and you need to constantly keep going until you're completely confident and clear and sure that it's absolutely perfect and will be judged however long it takes. It does not matter. In doing so you build from first principles. You will question. You will understand. You'll divide and conquer. You will create to-dos. Create to-dos that will create the other to-dos and essentially keep building and building until by the end of it I will then open up a browser and you will obviously run in local host and we will then test everything out and feel for it and see if it is truly done from first principles and every single detail needs to be done and the importance of doing every single detail is just understanding what truly needs to be done and spending a very very very long time thoughtfully brainstorming and reasoning towards what should be done.
