WEBVTT 00:00.200 --> 00:02.240 And welcome back to cursor. 00:02.240 --> 00:07.440 And here we are in week three the crew folder. 00:07.480 --> 00:08.280 How exciting. 00:08.320 --> 00:11.560 Let's open it up to see what treasures I have in store for you. 00:11.920 --> 00:13.760 And it's completely empty. 00:13.800 --> 00:15.640 It won't be empty for you, but it's empty for me. 00:15.640 --> 00:19.040 Because this is starting from nothing. 00:19.080 --> 00:20.680 The way that some of you like me to do it. 00:20.680 --> 00:22.320 Which is, uh, gonna happen this time. 00:22.320 --> 00:23.800 Because that's the way that crew works. 00:24.080 --> 00:31.200 So we will begin then by opening up a command line like this, a terminal in crew, which you'll remember 00:31.200 --> 00:33.520 is control and the tick on a mac. 00:33.560 --> 00:36.200 That is really the control button on the bottom left. 00:36.600 --> 00:41.880 And, uh, then, uh, or it's the view menu and terminal if you're using menus. 00:42.120 --> 00:47.960 So then what I'm going to do is I'm going to first change directory to go into the third directory. 00:47.960 --> 00:56.720 Right now we are in crew and I'm going to create a new crew project, which I do by saying crew I create 00:56.960 --> 00:57.640 crew. 00:58.080 --> 00:59.840 And then the name of the project. 00:59.840 --> 01:06.620 And we are going to call this project debate For reasons that will become obvious, but probably already 01:06.660 --> 01:12.580 are, and it first asks us a question, and to read the question, I'll have to make this a bit larger. 01:12.980 --> 01:18.500 Um, and this is because when you first create a project, it puts in place, as I mentioned, some 01:18.500 --> 01:21.900 scaffolding, some sort of basic project framework. 01:21.940 --> 01:25.980 And in order to set that up, it wants to know which model would you like me to start with. 01:26.020 --> 01:31.700 So we're not necessarily fixing this, but we can start by saying open AI and we can always change it 01:31.700 --> 01:32.340 later. 01:32.860 --> 01:38.500 Select a model to use and we can choose GPT four or mini to keep it nice and cheap. 01:38.900 --> 01:40.460 And then enter your key. 01:40.500 --> 01:45.580 Now at this point we should definitely just press enter because we already have a dot env file. 01:45.580 --> 01:48.180 It's trying to build env files for us. 01:48.180 --> 01:49.140 We don't need that. 01:49.420 --> 01:54.380 We press enter and you'll see right here that it's created a bunch of files. 01:54.660 --> 01:59.660 And I'm going to remove the terminal for a second so that we can take a look at it, because they have 01:59.660 --> 02:02.180 appeared over on the left. 02:02.700 --> 02:08.560 Now one thing to get in mind is that when when you're looking at the explorer in cursor or in VSCode, 02:08.800 --> 02:14.520 if there's a directory like crew that only has one other directory called debate, then it shows like 02:14.520 --> 02:14.720 this. 02:14.720 --> 02:18.720 It doesn't bother showing multiple files, multiple folders under it. 02:18.720 --> 02:20.080 And that can be a little bit confusing. 02:20.080 --> 02:24.080 So we might go back into the terminal and just make a new directory. 02:24.080 --> 02:26.720 Let's let's make a directory and call it other. 02:27.360 --> 02:30.560 And when I do that you see what just happened. 02:30.840 --> 02:35.320 Now if we come in here, you'll see that there's both debate and there's an empty folder called other, 02:35.320 --> 02:37.840 which is going to make it a little bit easier on the eyes. 02:38.400 --> 02:38.920 Okay. 02:39.360 --> 02:44.080 So now let's have a quick look at what has crew created for us. 02:44.400 --> 02:50.320 So under debate, which is the name of our crew that we're about to make a debate crew, as you've probably 02:50.320 --> 02:57.320 guessed, there is a folder called knowledge and that has a file user preference, and that has some 02:57.320 --> 02:59.800 stuff about the person who's the the user. 02:59.800 --> 03:00.960 And you can change this. 03:00.960 --> 03:05.200 This would be background information that would be given to the model if we made it use of it, which 03:05.200 --> 03:05.960 we will not. 03:06.000 --> 03:11.780 So this is a sort of an example of some of the scaffolding that's created in case we need to use it. 03:12.340 --> 03:15.020 Then there is a folder called debate. 03:15.300 --> 03:15.500 Sorry. 03:15.500 --> 03:17.220 There's a folder called source. 03:17.220 --> 03:20.340 And under that folder there is a single folder called debate. 03:20.340 --> 03:25.300 And again you're seeing it in this way in the explorer because there are no other folders other than 03:25.340 --> 03:26.940 debate under source. 03:27.220 --> 03:33.300 So sorry to recap, under crew we have a folder called debate, which is the name of of the project 03:33.700 --> 03:40.100 that has a sub folder subdirectory source SLC and that has a subdirectory also with the project's name 03:40.140 --> 03:40.820 debate. 03:41.260 --> 03:42.980 And that is where we are right now. 03:43.180 --> 03:46.060 And this is the this is the most important directory of them all. 03:46.100 --> 03:49.940 This this directory named the project underneath source. 03:49.980 --> 03:52.020 And that has a few things in it. 03:52.060 --> 03:54.460 It has a config directory. 03:54.460 --> 03:59.620 The config directory has two YAML files agents and tasks. 03:59.740 --> 04:00.500 And here they are. 04:00.540 --> 04:05.540 And they're set up with some default example code in there that we will come back and look at in just 04:05.540 --> 04:06.260 a second. 04:07.260 --> 04:13.160 There is a tools folder that has just, again, some scaffolding, some some, some basic stuff here 04:13.160 --> 04:15.720 that we might want to fill in later that we won't do this time. 04:16.280 --> 04:23.480 And then if we come into the root folder of debate, you'll see that there is a file, a module called 04:23.480 --> 04:29.160 crew dot Pi which has a bunch of scaffolding again, and then a main dot pi. 04:29.680 --> 04:35.160 So there we have it crew, the module, which is actually the one which brings together our crew, and 04:35.160 --> 04:38.400 it has the decorators that I mentioned to you, main. 04:38.560 --> 04:45.080 And then the two YAML files under config that has all been set up for us, ready for us to build our 04:45.080 --> 04:46.080 first crew. 04:46.760 --> 04:47.440 All right. 04:47.440 --> 04:54.320 So we are now going to go and define our YAML, our configuration for our agents and our tasks, starting 04:54.320 --> 04:57.600 over here with the agents YAML file. 04:58.000 --> 05:01.960 And this contains some default some sort of scaffolding. 05:01.960 --> 05:08.360 Some example agents that are called the researcher and the reporting analyst are the two examples that's 05:08.360 --> 05:08.840 given. 05:08.840 --> 05:11.620 And we're going to change these to being what we're looking to build. 05:11.620 --> 05:14.220 And of course, we're looking to build a debate team. 05:14.420 --> 05:17.300 And in fact, we only need two agents for what we're looking to do. 05:17.300 --> 05:19.220 We want an agent that will be the debater. 05:19.460 --> 05:24.340 Our one agent is going to play both roles of being for and against the the motion. 05:24.660 --> 05:28.380 And then we will have a judge and those will be our, our two agents. 05:28.380 --> 05:30.260 And now we need to describe what they are. 05:30.460 --> 05:33.420 And so the, the role is the first thing that we say here. 05:33.420 --> 05:37.460 And we're going to say a compelling debater right there. 05:37.660 --> 05:37.980 Okay. 05:38.020 --> 05:43.380 And now the goal is what what it's it's looking to achieve the objectives. 05:43.580 --> 05:49.540 And so let's see I'm going to actually copy across one that I did earlier. 05:49.540 --> 05:51.260 So you don't have to watch me typing everything. 05:51.260 --> 05:56.020 But we're going to present a clear argument either in favor of or against the motion. 05:56.020 --> 06:02.100 And the motion is and this is important, this little thing in in curly braces. 06:02.100 --> 06:05.780 Here is where you can effectively make this a template. 06:05.780 --> 06:10.820 That is something that's going to get defined when you run this agent framework. 06:10.820 --> 06:17.240 When we end up saying, Q I run, we are going to specify what we want motion to be, and we're actually 06:17.240 --> 06:19.640 going to specify that in Main.py. 06:19.880 --> 06:21.120 So keep that in mind. 06:21.120 --> 06:25.600 In Main.py we're going to have to set what is motion, the motion of the debate. 06:25.640 --> 06:28.840 The thing that we're putting forward the proposal that they will debate. 06:29.080 --> 06:29.560 Okay. 06:29.600 --> 06:37.440 And so now we have a back story, which is where we set the the it's really we know that this is the 06:37.440 --> 06:39.520 system prompt or a big part of it. 06:39.520 --> 06:46.040 But in crew land, we want to think of this as the, as the sort of framing of this, of this agent, 06:46.040 --> 06:46.960 the back story. 06:47.160 --> 06:52.320 You're an experienced debater with a knack for giving concise but convincing arguments. 06:52.320 --> 06:54.000 The motion is so on. 06:54.480 --> 06:58.080 So that is the definition of our agent, our debater agent. 06:58.080 --> 07:02.800 And that will apply both for one that is presenting for an argument and against it. 07:02.800 --> 07:06.400 And of course we'll be using tasks to distinguish between them. 07:06.960 --> 07:09.320 But now let's define our judge. 07:09.520 --> 07:12.520 So we are going to give the judge a role. 07:12.520 --> 07:17.060 And the role we will say is decide the winner of the debate. 07:17.060 --> 07:19.420 Look at how cursor even suggests what this should be. 07:19.660 --> 07:24.580 Let's say based on the arguments presented, let's keep it short. 07:25.420 --> 07:30.740 And then the goal I will take one that I wrote earlier because it's a couple of sentences. 07:30.740 --> 07:34.740 You can see that that amazingly cursor comes up with natural language. 07:34.780 --> 07:36.460 It's just great for these things already. 07:36.460 --> 07:40.900 So you can even define your agents just by letting cursor describe them. 07:41.180 --> 07:47.220 And the back story here I'm going to copy and paste in a nice juicy back story. 07:47.500 --> 07:48.660 And here it is. 07:48.820 --> 07:54.940 You're a fair judge with a reputation for weighing up arguments without factoring in your own views 07:54.980 --> 07:58.100 and making a decision based purely on the merits of the argument. 07:58.100 --> 07:59.220 The motion is blah. 07:59.420 --> 08:03.220 So that's the sort of good way to set things like the backstory. 08:03.380 --> 08:09.340 And again, on the one hand, one way of thinking about this is that this is the kind of backstory that 08:09.340 --> 08:14.180 an LLM is going to take into account in setting the context for this role. 08:14.580 --> 08:21.320 The other, more scientific way is just to always keep in mind that what Llms are doing is predicting 08:21.320 --> 08:24.760 the most likely next token to follow an input. 08:25.000 --> 08:31.440 And the point is that if this backstory is part of the input, then you are increasing the probability 08:31.440 --> 08:37.080 that the output tokens will be consistent with this, because things that are seen at training time 08:37.080 --> 08:43.880 that have that kind of backstory often predict tokens consistent with that backstory. 08:43.880 --> 08:48.760 So that's the the more scientific way of thinking about why this tends to work really well. 08:49.040 --> 08:49.680 All right. 08:49.840 --> 08:55.800 And then the final thing I'm going to add in here is you can also specify what model to use. 08:55.840 --> 08:58.600 And you can actually you can just have GPT four or mini. 08:58.640 --> 09:06.720 Or if you want to really spell it out then you say OpenAI GPT four mini, but it assumes OpenAI by default 09:06.720 --> 09:07.760 for that model. 09:07.800 --> 09:08.560 What am I doing here? 09:08.640 --> 09:09.600 Model colon. 09:09.800 --> 09:10.280 There we go. 09:10.320 --> 09:11.920 Luckily, cursor to the rescue. 09:12.440 --> 09:18.040 And this then is our YAML definition of the agents. 09:18.280 --> 09:19.680 Next up is tasks.
