The greatest AI engineering workflow of all time revealed (Herdr)

0:00I have figured out the greatest AI vibe coding setup of all time. I'm no longer using the Claude code or Codex desktop apps. They're completely dead. I'm using a new free app called Herder and you have to be using it. By the way, not sponsored at all. I just absolutely love this tool and I promise you need to be using it. Over the last couple months I have built more apps, written more code

0:21than any other time in my entire life. The best part is I'm doing that all while I playing video games and enjoying my life. It allows you to get way more work done while doing things you love. I'm about to show you it all. I'm about to show you how to spin up armies of agents while you do other things and enjoy your life. I'll show you how to set it up, use it, all my master tips, all my secrets. We're going to go through it all. If you like building things with AI, even even if you're a complete beginner, this is the video for you. You have to stick around to the

0:51end. Now let's lock in and get into it. So this is Herder and I know this might look a little intimidating, but stick with me here because I am very confident this is the best way to vibe code with AI ever. This is the best way to build things with AI ever. I promise you. What I'm about to show you I think is way more efficient, quicker, better than using Claude code desktop app or Codex desktop app. What you're looking at here is your terminal, but it is a new version of your terminal that allows you to manage a ton of agents really really easily. Basically what we're looking at

1:24is a few different things. On the left-hand side are all your machines and spaces. So I have my local Mac Studio machine here. I have my Omachi laptop here. And in each one of my devices, we have what's called spaces and these are basically your projects. So I'm working on many different projects at once. I'm working on Henry intelligent machines. I have one video game. I have a newsletter studio. I have another video game I'm building. I have another version of Henry I'm building. And that's just on my Mac Studio. I also have projects on my Omachi laptop going for another video

1:56game. I I like video games, sorry. Another video game I'm building. So, it's all my projects spread across all my machines and I can work on them all in this one place right here in this terminal. And what you can see happens as I click around and go into my different projects is what happens in the middle of my screen changes. So, for instance, if I go to my video game, you can see in the middle of my screen are all these different tabs. Each one of these tabs being a different AI agent that's doing something different. So, VGF is my video game. I have an agent

2:26that's a project manager, one that's working on core gameplay, one that's working on design, one that's working on weapons and loot, the map, sound. Each one of these tabs is a completely different agent. And what's great is and what makes this better than the Codex desktop app and Claude Code desktop app, these can be completely different agents. So, for instance, in running the

2:44game, I have a Claude Code agent going. On progression, I have a Codex agent going. If I wanted like a Gemini Argon 4 agent going, I could do that in a different tab. So, I have all these agents across all these multiple apps working together on this one project inside Herder. I am managing a herd of agents and it's really, really good. In the bottom left, you can see basically my list of all my agents across all of my projects and all my devices. And as they work and complete tasks, they go to the top of the list. And in a second, I'll go through setup and all that and

3:17we'll build an app together. We'll do all the fun things. I just kind of want to walk you through the UI first before we do that. But, this is your list of agents in basically chronological order of them getting things done. And so, all you need to do to get work done with these agents is sit here, you wait for one of your agents to finish work, you click on them, and then you give them another command, and they start working, and you go to the next one, the next one, the next one, and you just get so much more done than you ever have in

3:42your entire life because you're so nicely organized here. So, I come home, I'm working on my computer, and I go on here, and by the way, I'll show you me doing this work on my phone, on my Apple Watch, all these cool things in a second. But I come home, I go, "Okay, I want to work on my CC game." I come in here, I talk to one of my agents, I give them some tasks, I can switch over to one of my other projects, come in here, give them tasks. I go between all my different agents, make sure they're working. I go on to my other devices. So

4:08now I'm spinning up agents on my other computers, all from this one terminal. It is so efficient, it's so nice, it's so easy to use. And I know there's a lot going on here. We'll go through the setup in a second. I just want to give you a taste for how much you can get done with this. And again, I know half the comments are going to be, "Alex, you're being paid by Herder. This is This is a sneaky payment." For those that come in my comments and accuse me of being sponsored by free open-source tools, you're absolutely insane in your

4:35mind, okay? You just You're just crazy. But anyway, getting back to this. So speaking of open-source, one of the great benefits to this being open-source is you can customize this any way you want. So I've done some fun, interesting things to customize this, which I'll give you links to show you how to do in a second. One of those things is I built this little circle here, and I'll link this to you so you can download it as well. I call this Herder HUD. I built

4:59this myself. It's basically this circle. It stays on top of your screen, so it goes on top of whatever you have on your screen, whether it's other apps, whether it's video games, which I'll show you in a second. And it allows you to actually interact with any of your agents, no matter what you're doing on your computer. So I click it, and on the left-hand side, I can see all of my agents, and be able to communicate with them, see what the last thing they did is, and send them messages, and send them prompts so they can constantly be working. The reason why I love this, and

5:28why this has become my favorite workflow ever, is now I can talk to my Herder agents, no matter what I'm doing on my computer. So for instance, say I'm playing this new game I'm building called Null District, and I And I want to get work done while I'm playing it, right? That's what I don't know if you're like me, but ever since AI agents started coming out I started feel like really guilty when I'm not like getting

5:51work done and not being productive. Well, this fixed that. So, say I'm playing my new game I'm building and I have my Herder HUD on my screen right here and just put it over the corner so it's not blocking anything. I'm playing the game, I'm playing the game, and then all of a sudden if I feel like I want to get some work done, I can click the Herder HUD and start talking to my agents. And then as I'm playing I'll actually get alerts that my agents are getting work done. So, the notification has went up one I know I have a notification and I can click it and I

6:17can see that my agent messaged me and I can keep working with it here. So, now I'm able to not only organize my agents really well, but I'm even able to work with them while I'm doing other things. So, we got World of Warcraft forever coming out in 2 weeks. I'm going to play the absolute hell out of that. Now I can actually get work done and code and build apps while I'm playing the games, which is amazing. Now, I've showed you all the cool things it can do. Let's talk about setup so we can get you on this as well. There's no extra cost here. You don't have to sign up for any

6:47more accounts. This works with all your existing Codex and ChatGPT and Claude code, whatever agents you have it works with it all cuz it's all in the terminal. Let's go into actually setting this up and using it. And by the way, this is totally beginner-friendly. I know this is like the terminal and the terminal is like super intimidating to people, right? They think anything terminal related is only for hackers and coders and No, this is beginner-friendly. No skill level needed for this. Super easy to set up. Oh, and by the way, one thing before I show setup as well, what's really cool here is it allows your terminal to be

7:16clickable. So, as you saw earlier, I was clicking around. I'm clicking all my different projects and all my different agents here. Your terminal is now clickable so it's basically like it's own app, which is really amazing, too. So, we've gone through the benefits of Herder, right? The fact that you can work on multiple projects the same time, the fact that you can work on multiple devices at the same time, the fact that you can work with multiple agents across Codex, Claude code, Gemini, Cursor, whatever you're using, Grok, and the fact that it's just a great way to work with agents quickly because they list all your agents in one place. We went

7:48through all the benefits. Now, let's set up let's get it up and running. So, good news, setup for Herder is unbelievably easy. I'll put the link down below. You take this one command, you paste it into your terminal, and you have Herder all set up. Once you have it installed, all you do is type Herder into your terminal, you hit enter, and it opens up the screen you see here. From there, you just click new right there. I know it's a little hidden. You hit new right there. That creates a space. Again, a

8:13space is basically a project, right? It's your project that's going to have multiple tabs in it that are all your different agents. You click new. Once you're in new, it's going to open up a new tab in a new terminal like this. Then you just want to make a folder for whatever this new project we're going to work in is. I'm going to say Herder example. I'm going to hit enter, then I'm going to CD into that. So, make dir makes the folder in whatever folder

8:38you're in. Then you CD into that folder. You hit enter. Now you're in that folder, and now your space is named after your folder. Now we can set up our workspace in here. So, we're in the space. Now, let's say you want to use Claude code, you want to use Codex, whatever you want to use, you would just type in whatever you want to use. I'm using Codex. Boom, Codex opens up. We now have an agent in here. Say we want to build a game test. That's the example we're going to build together. Say we're

9:04going to use Herder to build a game. I'll show you the most efficient way for doing this. What we'll do is we'll have our kind of main agent here. Maybe we'll rename this to gameplay. And enter. Now that's our gameplay agent. Maybe we want a maps agent. So, we'll say maps. It could edit the map. Maybe I want to use Codex for this. Maybe I want a models

9:23agent that does all the 3D generation. I'll hit enter on that. And maybe we want to use Claude for this cuz Claude is a little bit better for 3D models. I really like Opus 55 for 3D models. So, I I did Claude for this. Now we have Claude for models, Codex for maps, Codex for gameplay. Maybe we have an agent for testing. So maybe we want an agent that says, "Hey, everything's good to go. Do you want to test the game for us?" And it does the game testing for us. For that, I'll use Codex. And then lastly, we'll just have a terminal tab. This is

9:51one where is a terminal, so we can run commands, we can open up the game with a command, whatever we want to do. This is just our terminal. And so now we're set up to build this new game together. We have our Space Herder X, and then we have our different agents, gameplay, maps, models, testing. What's cool is they can all communicate with each other. So if we go to gameplay and say, "Hey, use the maps agent to spin up whatever." It can do that. And we have all our agents working together side by side, and we can click quickly work between all of them to get a ton of work

10:19done. So I highly recommend you pause here and do this alongside with me. Do the setup I just showed you. Get set up. Build this game with me. Put out the new space here. Build the different tabs so we can work together on this, and we can each build something really, really cool. Then after is what we'll do is we'll test the game and all that, and then I'll show you all the cool little neat tricks you can do, like using Herder HUD. I'll show you how to set up this Herder HUD so you can go, play video games, do other things on your computer, and have your Herder agents

10:46all ready to go. I'll show you how I built an Apple Watch app so I can talk to my Herder agents on my Apple Watch. I'll show you all those little cool things. Thing but we have Herder open. Open it with me so you can work alongside with me here. We set up our different agents. I'm going to start giving prompts to each so I can show you kind of the multitasking we can do in here. And then I'll show you the workflow of using them. I'm going to use Codex for all these. The reason being is I used up all my usage for Claude code

11:13this week already. I've spent about $3,000 in credits already on Claude code. So we're going to use Codex. So I've been super addicted to roguelike games lately. So let's build one of those. So what we're going to do is this. We're going to start off with our gameplay agent. Make your first tab in

11:29your workspace kind of your main agent. This is the one you'll be talking to the most and you have your other tabs, your other agents kind of be your secondary agents. So, we're going to use our gameplay one as our main one. We're going to describe the game we want to build. So, here's the prompt I'm going to give it. I want to build a rogue-like game using 3.js. I want it to be a top-down demon-slaying game like Diablo where each level you get more and more demons, but in between levels you choose a specific power to get or attributes to level up. It should be a dark demon-like

11:56theme similar to Diablo with fun satisfying gameplay and in-depth, beautiful, stylistic graphics. I'll put this prompt down below. I highly encourage you build this out with me. You know, if you do this with me, you'll have the beginning of a really awesome game that you can then after this video ends go and customize on your own and make something cool for yourself that maybe you put online and start making money off of. So, we're going to do this. We're going to hit enter. Now, our

12:19Codex agent is going to get to work. Once the base of this game is built out by this one agent, we can begin our multi-multitask process with our other agents. I'd like to get kind of the base done with one agent, then we can start multitasking with the other agents. All right, looks like it is done. Let's test this out. Let's play it locally and see how it goes. I mean, I can just tell

12:40already these graphics are incredible. Let me make this the size of the recording here. All right, let's enter the descent. Let's just see how this is and then we'll go into improving this with Herder. This is actually not bad. This for a one-shot game, this is pretty good. All right, so now we we defeat the first wave, we can choose our upgrade path. Find the weakness to get 20%

13:00higher chance to critically strike. Increase your strike radius by 25%, gain 30 maximum health and restore it fully. Let's do that. Let's get more health. I think health's probably important here. Okay, this is looking good. I'm thinking of some things we can improve. So, what we can do is we can use an agent to improve the weapons. Let's deal 30% more damage. So, maybe we get like more weapons, more power-ups, things like that. I'm just kind of going to be honest, I'm kind of addicted to the game at the moment. Let me just get through this. Space, I can do that. Okay, so there is powers. There is powers, but we

13:30got to get more of them. All right. So, we test this game out. I actually think it's pretty impressive for a one-shot game. Let's go back into Herder so I can show you some strategies here. So, we got the basic gameplay down, right? We have a vertical of the game done. Now, let's move on and start multitasking a little bit. This is what I really like about Herder is that you can multitask not only across devices. You have agents going on all your computers all your devices, not only across projects, but inside the project you can have a lot of agents going at the same time. So, I'm

14:02going to create a new agent here. I'm going to call it loot. So, we have an agent in charge of loot. We're going to open up Codex in there. And let's do this. I'm going to say, "Let's add droppable loot and weapons, including weapons and money. We can eventually spend." I'm going to hit enter on that.

14:23So, now we have one agent going there. Let's go to models. I'm just going to open up Codex and I'm going to say, "Let's add many more different enemy types with different abilities." I'm going to hit enter on that. On the map, let's expand the map and make it bigger with more interesting parts to it and even chests with money and loot. We're going to hit enter on that. We're going to go back to gameplay. I'm going to say, "Let's add class abilities that I can unlock as we advance in the game." And I'm going to hit enter. And just like that, we now have agents going across

15:08the board. If we look over on our left-hand side here in the agents in the bottom left, we can see those agents working. When they finish, they'll move to the top of our list, right? So, now we can get in a more kind of efficient workflow here where I just keep my eyes, instead of clicking across all these different tabs like you would in a Codex or a Claude Code, I just keep an eye on my list. I wait for my agents to finish, their status to turn to done, and then I can just click, and you can see the loot

15:35one's already done. I can click there. All right, it already made weapons. Weapon pickups are in the game, collecting gold the balance. I'm checking the gold survives. Boom, good to go. So, I just see the agents move to the top of list. I click, I see what needs to be done next. This is a really efficient workflow that for me has helped make it so much faster. Let me even show you something I've been working on because again, this is open source. You can build out so many cool things here. I actually built my own custom app here. If we click on This is on the iPhone. I can go in here and I

16:04can see all my Herder agents in here. So, as you can see here, there's a Herder X, that app we or the project we just built. I can click in. I can see what we have to what the agent has to say here, and I can keep sending messages even on the go. And I can update this any way I want. If I want to add different features, functionality, I can do that on my own all because the Herder is open source. And this all just came in from me going in. You can see Herder Watch project here. I went in there and said, "Hey, build me an iPhone

16:30app, build me an Apple Watch app." And now I get all my Herder agents on the go really easily. No subscription necessary or anything like that. All right, let's go back in here and check on the status of our agents. All right, we have a new Herder agent at the top here. It looks like the models is done. Added eight new enemy types. They're in there and good to go. The map is still working. They're still extending the map, so we'll leave that be. And then the gameplay with the additional classes is still going as well. As you can see here, I This is real time. I cut out some of the pauses

16:57in between me saying things, but overall, we're like 5 minutes in here, and we have a game going. We have five different agents working on it, and we're almost set here. Like this shows you the efficiency gains from Herder. I'm thinking about doing like a super deep dive video specifically on gaming. I'm like a huge nerd. I think gaming in AI is like the biggest economic opportunity of all time right now. It's like a $200 billion industry that's about to get completely disrupted. Do you want like a super deep dive video on gaming? Like me showing you all the parts, 3D models, all that, how to build

17:31it all? Do you want like a dedicated video? Let me know down below. I'll make a fully dedicated like Opus 55 video on it. Also, if you learned anything at all as this is going, leave a like down below. Subscribe. Turn on critical. Turn on notifications cuz the moment new tech comes out, the moment new workflows come out, I make videos on it. I really hope these are helpful. I hope you're getting something out of them cuz I I just love making them so much. So, thank you for

17:54watching this. But, we're not done yet. Let's see how this game is going. Map is still expanding. Loot is good to go. We got brand new loot in here. Let's test this out right when this finishes. All right, looks like everything finished. Let's test this out here. I'm going to hit refresh. Let's enter the descent. Looks like we got new things that unlock as we go along here. All right, we have

18:12different classes now. I like this. Blood and steel ash. I'm always an elemental guy. When wild comes out in a couple weeks, I'm going to be an undead mage. So, let's go with the pyromancer. It gives us a cinder fan with Q and falling sun with R. All right, here we go. So, I'm going to hit Q. I got to wait till I level two to do that. All right, so we're just we're just fighting

18:29here with the sword. All right, they all drop gold like in Diablo. That's great. All right, next one. Every strike sends a piercing bolt of hellfire through your enemies. That sounds great. That sounds like Diablo. We have weapon type. Pick up the weapon. Shoot, I'm dying here. Okay, I like that. Look, you see all the different types of enemies. That's cool. It's blocking. It's got a shield. We made it through. Okay, let's deal 30% more

18:48damage for sure. Let's pick all this up. Okay, cool. This looks good. And there's loot. I forgot about the loot. F to open the chest. Nice, we got some more loot there. Q. Look at that, we got the fire. We got the fire. I got explosions. This is sick. Game looks good. That is a taste of why the multitasking inheritor is so good. You know, another part I really want to emphasize here is not only the multitasking in the project, but across projects as well. I have all my different projects I'm working on, a couple different versions of Henry, my newsletter studio I'm building, a few

19:21other things, and even across devices. I have my Omachi laptop with that which has Herder going. To set any of this up, you can just go to any of your agents and say, "Hey, set it up across my devices, whatever you need." It'll do it for you, get it set up well. But, this is the recommended workflow, right? Have kind of your main agent, have tabs for other parts of your app, and you send prompts across your agents, and then you watch your agent list in the bottom left, wait for them to finish, go to any of them with green dots, and then send them the next prompt, send them the next

19:49prompt, send them the next prompt. You will get way more done than you expect. So, I showed you my Herder app on my phone. Another big one here is Herder HUD. This is a plugin I built myself, I vibe coded it myself. Basically, the way it works is it's this H button you see here, it floats on top of your screen, it stays on top of anything you have on

20:10your computer computer, including games. So, I'll play games on my computer, and I'll have this on top of it, anything you want, and it always keeps your Herder agents above everything else. So, it's a small, tiny dot, and then when one agent finishes, you get a little notification, you can click it, and then you get this nice modal that has all your agents and the ability to send prompts to those agents from here. This is great if you're a gamer like me, this is great if you do other things on your computer other than vibe coding, cuz you can always have this up, and then you

20:40click it, you quickly send prompts, and you close it. This is how I'm going to be productive during World of Warcraft when that launches in 2 weeks. So, I'm really pumped about that. I'll put a link for it down below as well for Herder HUD. It's just an open source GitHub repo I created. Feel free to come in here. It has instructions, Mac, Windows, Linux, all of them. It has all the instructions in here on how to do it. You can come in here, leave it a star, fork it, do whatever you want, and uh use it. It's awesome. It's going to be really helpful if you get into Herder

21:05with like what I just showed you. This really has replaced basically all the desktop apps for me. I think it's so much more efficient of a workflow, and the fact that it's open source allows you to do cool things like make your own Herder hides, so you can have your own experience with Herder. I hope this was helpful. If you found it helpful at all, make sure to subscribe, like, turn on notifications, all of the algorithmic things. Free AI newsletter, number one AI newsletter on planet Earth, link for that down below as well. Hope you found

21:32this helpful. See you in the next video.
