This New Prompting Technique just 10X'd Claude Design

summarized

TLDR

The gauntlet loop (or design loop) is a new prompting technique for Claude that uses multiple independent critics to ruthlessly evaluate and iterate on designs, producing high-quality websites, graphics, and animations in one shot with far fewer mistakes. By spinning up fresh-context critics that check the brief, system alignment, and craft, Claude can self-correct without the usual back-and-forth, turning taste into a checklist.

Key points

  • The gauntlet loop solves Claude's inability to judge its own work by introducing independent critics that check the brief, system alignment, and craft.
  • You can create a design system in Claude Design to give the model a codified blueprint of typography, graphics, and style, which supercharges the loop.
  • The technique was popularized by Matt Schumer and covered by Robo Nuggets; it uses a loop of critics that iterate until the design meets all criteria.
  • A pre-built skill (the three-critic skill) makes it easy to set up the loop: export your design system, paste the skill into Claude, and use the /design-loop command.
  • The loop can produce carousels, HTML animations, and websites from a single prompt and a reference URL, dramatically reducing the number of iterations needed.
  • Costs vary: one example used 730k Haiku tokens and 1.9M Sonnet tokens; another used about 2M tokens for six rounds with three judges.
  • The technique is best reserved for high-stakes projects like templates or carousels, and you can stop the loop once it naturally converges.
  • Claude is recommended as the big model for its design taste, but you could experiment with other models like Deep Seek V4 Flash for the loop.

B can create beautiful designs, but a brand new prompting technique just solved its number one limitation. It's called the gauntlet loop, and it enables you to get incredible websites, graphics, presentations in one shot with [music] less mistakes. And in this video, I'll show you exactly how to do it, even if you're a complete beginner. So, if you haven't already, grab that beautiful coffee and let's dive straight in. So, it's called the gauntlet loop or the design loop, which is really fascinating. Now, as we know, Claude can build beautiful designs like this, for example. It can build HTML animations that look a little bit like this. Effectively, anything we want to, but the biggest problem that we have here is simply the fact that Claude judges its own homework. It says, "I think I've done it. In reality, has it really?" And you end up pulling your hair out and we need our hair if we can keep it. So, what is the solution and how is it fixed? Well, the gauntlet lube essentially is independent critics. Now, this was popularized by a guy called Matt Schumer. So, huge call out to Matt. This happened on X and Robo Nuggets covered it recently. So, huge shout out to Robo Nugs as well. Really freaking cool. Now, look at what this did in basically one shot. Check this out. Now, this has audio too. You can see this was basically using this exact technique. This is what it produced. Now, if you spent your whole childhood playing Call of Duty, hey, I'm not going to say anything and we've all been there. you'll know exactly how cool it is and how realistic it actually can be. We've even got Andre Kapathy chiming in as you can see. Basically talking about one of the ways we can think about a model's capability is it ability to build these beautiful expected >> 3D worlds in one shot. We've got Elon Mus chiming in. All that to say, it is very talented. And once you make it to the end of this video, you're going to be able to recreate in any design system or not something that is fantastic. I cannot wait to literally show you how cool this is. But the first thing we need to do is build a design system in Claude. This is optional but will really supercharge your entire systems. Now to access this just come over to the Claude website. Click on design in the bottom leftand corner and you can literally create your design system by here under design systems and then you can create a new design system. Think of this as having the world's best designer and he has at the moment what is known as a terrible memory something like Forest Gump/Mto style. And what we're going to do here is give them a codified blueprint, typographies, graphics, everything. So it understands exactly your specific design style. And you'll get something that looks like this. It is brilliant. And we can use this for everything. So this is an example of all I did. I gave it a presentation. I said, "Hey, I love this presentation. Turn it into a design system." So action one, take any design assets that you've got, give it to Claude, and it will turn it for you into a full design system. Then once you've done that, come over to share the top right and you're going to go ahead and export this out. Now the reason why you want to go ahead and export this out and again you can do it as project html that's absolutely fine because we they can use this in Claude to actually build something incredible using this technique. Now the reason why we're going to run this outside of Claude is purely because of the strength of this technique and it's the fact that what we need to do is spin up what are called fresh context critics. Effectively, what we're going to do is give Claude a reference design of, "Hey, I want it to look like this or be this." Give it a criteria, and it's going to spin up multiple critics who will ruthlessly challenge Claude's design, and it will go around in a loop, hence the called the gauntlet loop, as Matt said, or the design loop, until it reaches this end state, meaning that you have less back and forth, and you don't need to keep basically coming back and forth as much, and the first design is way better. So essentially taste becomes a checklist and I love that. I love my checklist and I love taste. You know we got an interview pre-flight tear down the bar build it. It's going to have critics. It's going to have everything. So for example, one critic can be the brief. So did you do what I asked? For example, if I say, "Hey, I want you to do ABCD EFG." Then one critic is just saying, "Hey, did you actually do the brief, bro?" And he might say, "Hey, bro, no, I didn't." And go back and change it. Then you could have the system. So is it really in line with the system? And then you've got the craft. So this could be for example rendered frames, never the code, and actually judges the bar all based dynamically on your prompt. So once we've created a system, you're going to export that just like I showed you. And the great news is I've actually built you a skill which makes this unbelievably easy. So step one, export your design system. Step two, and I've made this so easy, is just come down and grab the three critic skill. It explains what the three roles are. And all you're going to do is copy this whole page. Crl C. It will be the second link in the description below. You can grab that from my free resource community. Again, 100% free. You can grab it. No gatekeeping at all. Then you're going to over to Claude, open up a brand new chat, and just say, "Hey, turn this into a skill." And then come down, paste it all in, and then you'll be ready to go. And it will create once that's done a skill, which if you do for/ loop is called the design loop. So, we're going to test this across three levels of difficulty. And level one is going to be the carousel. So, for example, I found this carousel earlier and I thought this was absolutely gorgeous. And look, it's blown up. It's got 15,000 likes on Instagram. And let's just put it to the test and say, "Hey, can you actually, if I just gave you the URL, I'm not even going to tell you anything. I'm just going to give you the URL. Can you actually design this?" And look at this. This is the best prompt pairing. So, attempting in Switzerland, uh, different fonts basically beautiful design, looks gorgeous, really love it, really aesthetic. And then at the end, uh, you can come to Paris and you get all of these fonts for you, which is absolutely awesome. And by the way, if this entire thing is starting to sound a little bit like Spanish or you want to just level up your design game and your Claude code game, I'm going to put a link down below for the full Claude code masterass inside the community. It has stuff that I have never shared on YouTube. I get messages about this all the time. It has design systems, apps, building everything, you name it. And you get access to the full Aentic OS and like a gargantillion other things. cuz I'm going to put a link down below so you can grab that and get some serious high levels. Now, what we're going to do is literally copy this. Then head over to claw. You're going to open up a brand new window and you're going to do forward slash and you're going to go design loop like so. And then literally just say activate this skill. Okay. And what it might do once it's done that is it'll come back and it'll ask us a couple of questions. That's exactly how I built the skill for you. So you can just throw it in and then just get started basically. So here we go. I would like you to go ahead and I want you to look at this URL and build me a version of this for AI tool. So go through the Jack Roberts YouTube channel and find out all the tools that I mentioned and in the same design aesthetic um you know inspired by that design aesthetic just do me something covering all the top tools that I basically build. Bam come down drop this off and also it says any files I should work from and if you've connected everything together in this it also has access to that so be ready to rock and roll. And then guys look at this. Okay going to come down and let's go through all the designs that we've got. Seven AI tools claude code ships whole projects chat GPT daily thinking partner this is not bad right this is really cool and again common AI to get the full guide to all seven tools but this is wild again and you just give it one prompt and it runs and it does the whole thing I think this is fantastic now I wouldn't normally go ahead and do this because I like to do it in my own design style and build my own things but the fact that I can give it a reference image and it can go ahead and do that now imagine you overlay with your own design styles all these are 100% unique images and it's gone ahead and done that. Otherwise, this would have been a thousand back and forths. You know, I'd start, as I say, with no mustache, and then by the time I'm done, I'd have a huge mustache. That's how long it can take sometimes. Now, for the second level, I wanted to do something with my own design system. And funny enough, it's the exact thing that I use in all my presentations here. Uh, which is cool. And basically, I've got this design system on claw design. So, what I'm going to do is give it a prompt to build me a little bit of an animation. And as you can see, same process, design loop. I'm going to say use the below design system. And I want to make a beautiful HTML graphic that lasts 10 to 15 seconds that I can overlay with a blow sentence. The gauntlet loop is a technique that we can use in CL design to create beautiful websites, presentations, emails, HTML designs, and much more. And you can use it in three simple steps. Oh, and by the way, if you are new here, my name is Jack. I built and saw my LT tech startup with like a gazillion customers. And now I'm building my own AI startup and I share my channel all the cool stuff that works. And one of the reasons why I'm so passionate about design is because in my first tech startup, it was actually one of the things that everybody always commented on. And it genuinely led to uh investor conversations. It led to new clients and it really set the standard. So that's why I I I really passionately believe in it. And we have this design and you can judge for yourself how closely you think it nailed it. But look at this websites, presentations, emails, HTML designs. This is great. And this is run in the background whilst you're talking and you can brief, build and critique. And if you don't like these things, you can move them around. But just incredible that you can use just simply one of these things and get these kinds of outputs. And if you're wondering what does this cost, I'm going to show you that as well. and all the transparency because I can hear your wallet crying from through the screen right now. So don't worry, I'm going to say exactly what this is will cost in credits. The third one I want to show you is the website. So let's say I found this really cool one here which I think is fantastic. So credit to Almon who built this are kind of like you know numbers dropping down and moving around. Wouldn't that be really cool? So what we're going to do is copy this and do the exact same process design loop and let's see what it actually comes back with. All right guys, here we go. 4 404. Okay, cool. And we got all the things moving around. This is crazy. And can I I can actually do this as well. Do you know what guy? This has turned a disaster into something very fun. I mean, I might even just stop the video and play around with this for a few hours and see how I get on. See how many combinations I can get. This is actually very, very freaking fun. I love this. But again, what was the design reference? It wasn't even a website. It was just the idea of a website. It was more the concept or the thought of a website. And obviously, there's things we could do. We can improve it. But how amazing is that? But let's actually see behind the hood now cuz this is really important in terms of what does this cost and how do I use it? and what if any of limitations cuz I want to make sure you always get the full picture and this is it I guess limitation of the kind of solution and that's the fact that it spent 3 million tokens now in the skill that I've given you I delegate it out to sort of smaller models but you can see how this can add up over time then for the design loop itself again this had this was a system it was interview pre-flight checklist tear down a loop um basically and it was really good how it kind of broke everything down it showed the evolution three critics three blind spots covered and this is the issue can't grade its own homework. You can't be the judge, the jury, and the executioner. So, bring it in. And it just tells you what each thing caught. So, for example, this is why this is so valuable. Round one, three fells, no logos, color breaking, monochrome, loud words, underscaled. Round two, her mark was too small. Round three, lime ship was a second accent. Round four, and you can see there were 10 rounds to get to this point. And the thing is, if you give anything to Claude and say, "Hey, what's wrong with this?" If you ask it five times, you will get five different actors. So, it's like each of these critics are looking at it 10 times before you get the result, which is why it looked so high quality and why I think it's so cool. And actually, dude, honestly, in terms of the price for this one, not too bad. So, it's basically 730,000 Haiku tokens, which is not too bad. And Sonic was 1.9 million, which I think was great. And finally, we have the Gauntlet Loop. So, again, six rounds. This one took three judges, zero mercy. We don't give any mercy in the beautiful critical loop, which is cool. And this one came in at around 2 million tokens. Now, one of the things that I'm definitely going to be experimenting with going forward as well is doing the same loop over a longer period of time, maybe with like a Deep Seek V4 Flash or some other models. Again, if it sounds like magic or German, I'll put a link down below for the master class. Enjoy the community. But in the case, I think this system is honestly amazing. I'm so so impressed with the results we got on one shot. And so, the other good thing to bear in mind here is that the loop can eat your credits, which is important. So I would reserve this for your bigger things like the things that you really want to crush down and get ready like templates for example that you are then going to go and reuse like your carousels or big jobs or you could actually bring in other models like a Deep Seek V4. But you do want the big model to be clawed cuz it's got great design taste. Again, one piece per project and you can be the person who stops it once it's gone through automations, but I found when I went through rounds, it kind of ended naturally at a great point. And so now we've covered this incredible skill. The next thing that we're going to do is learn how to leverage that skill to build beautiful websites, which we can do in this video right
