1 00:00:00,000 --> 00:00:07,519 Okay, it's time for us to move on from Codex and move to antigravity, the last, the fourth of our 2 00:00:07,519 --> 00:00:12,560 list of four. And, you know, I can't resist but having this up a little bit more. I think that 3 00:00:12,560 --> 00:00:18,399 obviously Codex did a fantastic job. The bar is high for antigravity. It's worth pointing out that 4 00:00:18,399 --> 00:00:25,360 the reason Codex did so well is because we are using the absolute frontier frontier model now. 5 00:00:25,840 --> 00:00:31,200 Whilst we had it set to pick its own model before, but I'm pretty sure that with Cursor we were 6 00:00:31,200 --> 00:00:38,639 using Composer, which is Cursor's internal lower cost model that they have built, optimized for 7 00:00:38,639 --> 00:00:46,959 Cursor. This is good, but not at Codex level, not at GPT 5.2 Codex level. And then after that, 8 00:00:46,959 --> 00:00:53,360 I believe when we were using GitHub Copilot, I was using Claude Haiku 4.5, which is good, 9 00:00:53,360 --> 00:01:00,000 but again, it's a smaller model. Codex 5.2 and on high reasoning, really strong model. 10 00:01:00,000 --> 00:01:07,599 Strong model means strong results. That you can see for sure. Okay, enough. On to antigravity. 11 00:01:07,599 --> 00:01:14,400 All right, well, I am back. I'm back in Cursor again. I'm back in the instant project in Cursor 12 00:01:14,400 --> 00:01:19,199 because this is where we go to reset things. We might as well. It's just like a useful terminal 13 00:01:19,199 --> 00:01:24,239 to have open. I'm still in the projects directory. If you do a PWD, make sure that you are in 14 00:01:24,239 --> 00:01:29,680 projects or do CD dot dot if you're inside instant. And then what I'm going to do, of course, as 15 00:01:29,680 --> 00:01:36,879 before is I'm going to rename by doing move mv the Kanban folder, the whole folder to be Codex 16 00:01:36,879 --> 00:01:43,199 underscore Kanban. And once I've done this, that is that has been renamed. There's no more Kanban 17 00:01:43,199 --> 00:01:50,879 and I can now do a git clone to bring Kanban back down again. There it is. We've got ourselves a new 18 00:01:50,879 --> 00:01:57,120 fresh Kanban. It's time for us to try out antigravity. OK, here we are at antigravity's 19 00:01:57,120 --> 00:02:05,360 website is antigravity dot Google. You got a cool URL. And so it says experience liftoff with the 20 00:02:05,360 --> 00:02:11,039 next generation IDE. And there is a download for Mac OS. And I'm guessing you've got a download 21 00:02:11,039 --> 00:02:14,880 for and whatever your platform is. But there's also a download button up here where you can 22 00:02:14,880 --> 00:02:20,240 actually pick the one that you want and you should then download it. And if you're on a Mac, you'll 23 00:02:20,240 --> 00:02:24,800 have something where, as usual, you drag the icon into applications. If you're on a PC, you've got 24 00:02:24,800 --> 00:02:29,679 a little wizard. When you launch it, there'll be a few questions. You should just pick the default. 25 00:02:29,679 --> 00:02:35,199 Stick with what it wants. Pick whatever color scheme you like for everything else. Just stick 26 00:02:35,199 --> 00:02:40,639 with the defaults. Go through it and it should open up. And I'm guessing that you're going to 27 00:02:40,639 --> 00:02:47,199 see something that's going to look surprisingly familiar. Let's see. OK, so first up, first up, 28 00:02:47,199 --> 00:02:54,320 it looks kind of similar to Cursor again and to VS Code. And that's because it is VS Code again, 29 00:02:54,320 --> 00:03:01,279 like Cursor. It is just a clone of VS Code, a fork. They've remade VS Code for antigravity. 30 00:03:01,279 --> 00:03:05,600 That's why it's similar. It's because it's the same thing. And you may see exactly the screen 31 00:03:05,600 --> 00:03:11,360 I've got here. And if not, guess what you do? You go to File and New Window and then you will see 32 00:03:11,360 --> 00:03:17,119 this. Surprising, huh? Now, you should have already signed into Google with a Google Auth, with a 33 00:03:17,119 --> 00:03:21,919 Google account as part of downloading this. But if not, over here on the top right, this is where 34 00:03:21,919 --> 00:03:29,759 you set up your Google Auth login and would log in to Google in the usual way. And so that's 35 00:03:29,759 --> 00:03:35,119 how we've got to where we are. And you can see that we're facing a screen which has the usual 36 00:03:35,119 --> 00:03:38,960 stuff with an open folder and an agent conversation. This time, it's on the right. 37 00:03:38,960 --> 00:03:44,479 And it's time for us to open a folder. OK, I'm pressing Open Folder. I'm going to go into 38 00:03:44,479 --> 00:03:49,679 Projects. I'm going to go into Kanban. I'm going to open it. And here we have a very familiar 39 00:03:49,679 --> 00:03:56,479 looking screen with a middle area, files on the left. And over here on the right is our agent 40 00:03:56,479 --> 00:04:04,720 chat. And it's telling us about Gemini 3 Flash, frontier level intelligence, blazing fast speed. 41 00:04:05,279 --> 00:04:12,080 OK, and a generous and more generous quotas. OK, and so just to take you through what we see here, 42 00:04:12,080 --> 00:04:15,919 first up, you can see, hang on, let me just dismiss this. You can see that there is a, 43 00:04:16,640 --> 00:04:23,119 dismiss that. You can see there's the ability to choose between a planning mode or not. We'll 44 00:04:23,119 --> 00:04:28,559 leave it on planning mode. We've got a selection of models. And interestingly, you can see that 45 00:04:28,559 --> 00:04:35,040 Google offers the anthropic models as well as using the open source version of GPT-OSS. 46 00:04:35,839 --> 00:04:42,959 But we are going to leave it here. And yeah, we can now give this a whirl. 47 00:04:42,959 --> 00:04:45,920 All right, and if I could draw your attention here to the settings, 48 00:04:45,920 --> 00:04:50,160 anti-gravity settings on the bottom here. Click there. Up comes a few things that we can mess 49 00:04:50,160 --> 00:04:57,119 around with. First of all, Agent Autofix lints. So a lint error is when the code doesn't pass 50 00:04:57,119 --> 00:05:02,320 some basic checks about the way that it's been structured. And you can set that on, 51 00:05:02,320 --> 00:05:06,480 which we will do, which means that it will fix any of those kinds of errors that surface. 52 00:05:06,480 --> 00:05:12,000 Good practice to do that. And now here is like being able to control YOLO mode. 53 00:05:12,000 --> 00:05:17,839 If in doubt, leave this on request review so that it needs to check with you before. But I'm going 54 00:05:17,839 --> 00:05:24,079 to put this on to always proceed and always proceed. There's a rather nice agent decides 55 00:05:24,079 --> 00:05:28,959 option here where it can decide whether or not it wants to ask you for permission. But I'm going 56 00:05:28,959 --> 00:05:33,519 to be YOLOing all the way today. You should only do that if you're comfortable with it. 57 00:05:34,079 --> 00:05:40,640 All right. So those are some settings for us. And now we've got this on planning mode. We're 58 00:05:40,640 --> 00:05:45,920 almost ready to go. There's one more thing we need to do. Having a single file called agents.md 59 00:05:46,799 --> 00:05:51,519 has been something of a sort of evolving standard that people have just kind of adopted. 60 00:05:52,160 --> 00:05:56,640 Although, as you'll see, a Claude code uses Claude.md, but otherwise very similar. 61 00:05:57,200 --> 00:06:02,320 But antigravity has not adopted the standard. They've gone a different direction. So we are 62 00:06:02,320 --> 00:06:08,320 not going to use agents.md. But instead, we're going to click here, select all and copy all of 63 00:06:08,320 --> 00:06:14,880 that. So just edit menu, select all, edit menu, copy or command A, command C on a Mac, control A, 64 00:06:14,959 --> 00:06:21,600 control C on a PC. All right. And now instead of that, we're going to put this somewhere else. 65 00:06:21,600 --> 00:06:27,200 Okay. We're going to create a new folder in the project root, in Kanban. Right click anywhere 66 00:06:27,200 --> 00:06:33,839 here, select new folder, and we're going to call it .agent, like so. And then within .agent, 67 00:06:33,839 --> 00:06:38,239 and .agent is like a special folder that antigravity expects. And you can have different 68 00:06:38,239 --> 00:06:42,399 folders within this that tell it about different things. And in particular, there's an important 69 00:06:42,399 --> 00:06:49,279 folder called rules that tells it it's rules. And then within this folder, you can make markdown 70 00:06:49,279 --> 00:06:54,320 files. And we are only going to have one, and we will call it a new file. We can call it anything 71 00:06:54,320 --> 00:07:03,600 we want, but we'll call it like strategy.md. And when we do that, it comes up with this special 72 00:07:03,600 --> 00:07:09,519 look. It's expecting this to be in a certain way. First of all, there is an activation mode, 73 00:07:09,600 --> 00:07:15,600 which is telling antigravity in what circumstances does it need to read all of this into context. 74 00:07:15,600 --> 00:07:21,200 All right. And so we are going to say always on. It could also be manual. It could be model 75 00:07:21,200 --> 00:07:26,880 decision if we wanted the model to be able to choose. And I'm now going to paste in the content, 76 00:07:26,880 --> 00:07:33,040 which is the whole of our agents.md, and save that. And it's done. Always remember to save, 77 00:07:33,040 --> 00:07:38,559 by the way, command S on a Mac, control S on a PC, make sure that the dot disappears. So that 78 00:07:38,559 --> 00:07:44,880 is a saved file. Okay. We've saved that. And now I'm actually going to delete this agents.md to 79 00:07:44,880 --> 00:07:52,320 avoid any confusion here. We've only got our single rule, our strategy.md in the rules directory 80 00:07:52,320 --> 00:07:57,679 within the dot agent directory in the Kanban project route. And with that, we're actually 81 00:07:57,679 --> 00:08:03,359 ready to go. And so over here on the right, I'm going to say to Gemini that please go ahead, 82 00:08:04,320 --> 00:08:09,679 go ahead and see what it does. And it's off. And we're using, of course, 83 00:08:10,399 --> 00:08:17,200 oh, we're using Gemini 3 Pro. I've left it on. Okay. Gemini 3 Pro high. So this is on a big 84 00:08:17,200 --> 00:08:23,839 tier of Gemini. We're going with the strongest version and we will see how it fares with this. 85 00:08:23,839 --> 00:08:30,000 I will see you back here in a moment. Okay. Well, it's completed. It's finished. It's given me this 86 00:08:30,000 --> 00:08:36,000 summary here, the Kanban MVP walkthrough with this nice little thing with apparently a screenshot 87 00:08:36,000 --> 00:08:40,799 of it moving. How about that? Is that for real? Is this what it's actually going to look like? 88 00:08:40,799 --> 00:08:46,000 That would be cool. It's got like a recording of it. Isn't that crazy? And then here is the 89 00:08:46,000 --> 00:08:52,080 instructions on how to run it. Okay. And then we'll see here. It wants me to accept all the 90 00:08:52,080 --> 00:08:57,039 changes that it made. And it seems to be ready for me to try it. I do believe it is actually 91 00:08:57,039 --> 00:09:04,320 already running. So, okay, let's bring up a browser and let's see. Let's see how it does. 92 00:09:04,320 --> 00:09:09,760 Okay. So this is what I see in a browser. First of all, I should point out something you may have 93 00:09:09,760 --> 00:09:15,359 seen that while this was running, it was actually bringing up browsers and testing it itself, 94 00:09:15,359 --> 00:09:18,799 checking the screens look good. That's how I did that screen recording. And so I know it was 95 00:09:18,799 --> 00:09:24,400 actually real screen recording. And it also brought up this thing called Playwrights, which is where 96 00:09:24,400 --> 00:09:30,080 it drives a browser with browser automation software to run a series of tests. And you can 97 00:09:30,080 --> 00:09:34,960 also, you can see that it's in some of these tests, it was failing and it fixed them. And then 98 00:09:34,960 --> 00:09:39,039 it would then saw success. For some reason, it didn't actually seem to fix that last one. But 99 00:09:39,039 --> 00:09:43,200 anyways, it was working away, beavering away, doing all of this. And it's time for us to see 100 00:09:43,200 --> 00:09:48,799 what it actually looks like. And here it is. This is the result. Here is the result from 101 00:09:48,799 --> 00:09:53,840 Gemini through antigravity. Let's see what we make of it. And first up, I'd say, I think it 102 00:09:53,840 --> 00:09:59,359 looks pretty good. It looks fresh and clean. And I think it looks very good. We can flip things 103 00:09:59,359 --> 00:10:05,200 around. Yes, that all seems to work. Let's move that over there. Let's see if we can add a card. 104 00:10:05,760 --> 00:10:09,679 Enter cutter. Okay, that's a bit janky having like a local host thing there. But we'll say, 105 00:10:10,479 --> 00:10:18,239 okay. And then there it is. And now can we come in? Oh, we can't actually add a description to 106 00:10:18,239 --> 00:10:25,520 that. That seems a bit mediocre. And can we change this title? Yes, we can. This is good. 107 00:10:26,479 --> 00:10:32,080 There we go. That's done. Okay, that's great. So I'd say that this adding a new card is the 108 00:10:32,080 --> 00:10:37,119 only thing that feels a little bit simplistic. Let's see if we can't improve that.
