WEBVTT 00:00.240 --> 00:03.560 And welcome to crew week three, day three. 00:03.840 --> 00:06.720 It is time for us to build a new project. 00:06.760 --> 00:11.960 The stock picker that I'm looking forward to showing you a quick reminder on the five steps that we 00:11.960 --> 00:16.320 use to build a crew project from last time we use crew, I create crew. 00:16.600 --> 00:24.720 We fill in the YAML files, we complete the crew module, we update Main.py to set any inputs for doing 00:24.720 --> 00:27.760 the run, and then we call crew I run. 00:28.480 --> 00:32.680 This time we're going to be going deeper again in three new ways. 00:32.880 --> 00:36.200 First of all, structured outputs will have a comeback. 00:36.200 --> 00:37.320 We looked at them last week. 00:37.320 --> 00:39.160 We'll do them again with crew. 00:39.680 --> 00:43.480 We'll use a custom tool in addition to the Serp tool that we'll use again. 00:43.520 --> 00:45.640 We'll also build our own tool. 00:45.840 --> 00:53.080 And then thirdly, we will try out the hierarchical process allowing crew to manage the process of what 00:53.120 --> 00:54.160 task goes where. 00:54.200 --> 00:57.160 And as you'll see, we'll have a bit of an adventure with that. 00:57.200 --> 00:57.680 All right. 00:57.680 --> 00:58.760 Let's get started. 00:58.800 --> 00:59.400 Okay. 00:59.400 --> 01:00.800 Here we are back in cursor. 01:00.840 --> 01:04.200 Back in Project Directory three crew. 01:04.520 --> 01:09.400 And let's open this up and we will bring up a terminal window again. 01:09.400 --> 01:15.360 As before, we'll go into that directory and we're going to create our new project which is of course 01:15.360 --> 01:18.040 crew I create crew. 01:18.040 --> 01:25.440 And then the name of the project which is going to be Stock picker, a project to create and recommendations 01:25.440 --> 01:32.720 for investing in the stock market, bearing in mind that this is purely for our own investigatory purposes 01:32.720 --> 01:35.640 and you should not use this to make any trading decisions, please. 01:36.080 --> 01:36.440 Okay. 01:36.440 --> 01:39.880 We're going to select open AI as our provider. 01:40.080 --> 01:42.440 And we're going to choose GPT four and mini. 01:42.440 --> 01:45.240 And we're not going to set up any env variables. 01:45.400 --> 01:48.440 And the crew has been successfully created. 01:48.840 --> 01:49.640 All right. 01:49.640 --> 01:53.520 It's now first of all time for us to open up our stock picker. 01:53.840 --> 01:57.480 And as usual go into source, go into config. 01:57.480 --> 02:01.000 And the first step is to create our agents. 02:01.000 --> 02:03.870 So we will go ahead and do that now. 02:04.350 --> 02:04.790 Okay. 02:04.830 --> 02:07.630 So here we are in YAML. 02:07.630 --> 02:10.790 And we're going to create the agents for this project. 02:10.790 --> 02:12.310 And there's going to be a few of them. 02:12.710 --> 02:16.950 So I'm going to bring them in an agent at a time so that we can talk them through. 02:17.190 --> 02:21.110 So the first agent is called the trending Company Finder. 02:21.110 --> 02:26.910 And it's responsible for looking in the news and finding trending companies in a particular sector. 02:27.030 --> 02:27.990 So you read the news. 02:27.990 --> 02:32.110 You find 2 to 3 companies that are trending for further analysis. 02:32.150 --> 02:33.950 And we'll use GPT for a minute here. 02:33.950 --> 02:37.390 But you can of course substitute in whichever model you'd like. 02:37.390 --> 02:39.510 And it might be fun to play around with different ones. 02:40.070 --> 02:44.270 The next one we will use, and let me make sure I paste this in properly. 02:44.270 --> 02:44.950 There we go. 02:44.950 --> 02:46.990 Is a financial researcher. 02:47.310 --> 02:48.910 The financial researcher. 02:48.950 --> 02:54.030 Given details of trending companies you provide comprehensive analysis. 02:54.230 --> 02:58.550 So financial expert with a proven track record of deeply analyzing hot companies. 02:58.870 --> 03:03.310 Again we'll go with GPT four mini as the backstory. 03:03.750 --> 03:11.990 Okay one more agent that we're going to work with, and that next agent is going to be a stock picker. 03:12.470 --> 03:16.070 So we've done we've we've found trending companies in the news. 03:16.070 --> 03:19.110 We've researched those trending companies. 03:19.190 --> 03:21.350 What's left to do is to pick one. 03:21.550 --> 03:27.510 So the stock picker given a list of researched companies with investment potential, you select the 03:27.510 --> 03:32.710 best one for investment, notifying the user and then providing a detailed report. 03:32.750 --> 03:34.590 Don't pick the same company twice. 03:34.950 --> 03:40.310 You're a meticulous, skilled financial analyst with a proven track record of equity selection. 03:40.550 --> 03:44.710 These are all great ideas for well crafted prompts to be using. 03:44.910 --> 03:50.950 And again, we'll use GPT four mini for now and let's save that. 03:51.430 --> 03:53.910 I'm going to add in one more agent as well. 03:53.950 --> 03:56.830 A new agent for us to be exploring this time. 03:56.830 --> 03:59.630 And the new agent is going to be a manager. 03:59.830 --> 04:01.990 But I'm going to keep this manager very simple. 04:02.270 --> 04:06.870 The role is a manager, and I'm saying you're a skilled project manager who can delegate tasks to. 04:06.910 --> 04:12.190 In order to achieve your goal, which is your goal is to pick the best company for investment. 04:12.630 --> 04:13.550 And that's it. 04:13.550 --> 04:17.390 So very simple vanilla description of that agent. 04:17.390 --> 04:21.110 And therein there is our four agents for this project. 04:21.550 --> 04:22.470 So far so good. 04:22.510 --> 04:23.590 You like those four agents. 04:23.590 --> 04:25.990 It's time for us to define the tasks. 04:26.390 --> 04:31.150 And when defining tasks the trick is to be very clear, very simple. 04:31.350 --> 04:36.430 And so the first task is a find trending company's task. 04:36.670 --> 04:43.150 Find the top trending companies in the news in this sector by searching the latest news. 04:43.350 --> 04:49.150 Find new companies that you've not found before and the output, a list of trending companies in that 04:49.150 --> 04:49.790 sector. 04:50.190 --> 04:54.390 And we are going to say that assign it, of course, to the agent. 04:54.390 --> 04:59.630 The trending company finder is the agent that will work on this, and it will put it in an output file. 04:59.670 --> 05:05.590 Trending companies in, uh, output that you may be wondering why that says JSON. 05:05.590 --> 05:07.110 It will become clear in one second. 05:07.630 --> 05:08.390 Okay. 05:08.430 --> 05:11.750 So then going to have our next task. 05:11.790 --> 05:18.550 And our second task is going to be a research trending companies task. 05:18.710 --> 05:23.310 The description is given a list of trending companies provide a detailed analysis of each company in 05:23.310 --> 05:24.030 a report. 05:24.390 --> 05:27.590 And the agent of course will be the financial researcher. 05:27.630 --> 05:29.510 The second agent that we made. 05:29.510 --> 05:32.950 So this this 1 to 1 correspondence between a task and an agent right now. 05:33.510 --> 05:36.230 And we're giving it we're telling it to have some context. 05:36.230 --> 05:39.950 And the context is the find trending companies task. 05:40.350 --> 05:43.790 And we're asking it to put it in an output as well. 05:44.750 --> 05:48.590 And you can see that already cursor is one step ahead. 05:48.590 --> 05:51.030 But we're going to ignore cursor. 05:51.230 --> 05:53.310 And I'm going to put it in myself. 05:53.550 --> 05:57.390 The pick best company task is the final task in the list. 05:57.390 --> 06:03.470 It's of course assigns to the stock picker agent, and it is to analyze research findings, pick the 06:03.470 --> 06:07.630 best company for investment, then send a push notification to the user. 06:07.630 --> 06:08.580 That's a new one. 06:08.580 --> 06:12.300 You can imagine that it's going to be the tool that we will add, a tool that we've used before. 06:12.300 --> 06:18.820 But the first time in crew and we'll, we'll ask for a one sentence rationale and then respond with 06:18.820 --> 06:23.140 a detailed report on why you chose this company and which companies were not selected. 06:23.540 --> 06:26.860 And then the agent I just said was a stock picker. 06:27.020 --> 06:31.660 And the context is of course, the research trending companies. 06:32.140 --> 06:33.540 So there we have it. 06:33.580 --> 06:35.500 We've now defined our tasks. 06:35.780 --> 06:41.940 And again, it's worth noticing how I've made these prompts very instructive, very crisp. 06:41.940 --> 06:45.420 I've used consistent language with things like trending companies. 06:45.660 --> 06:51.220 All of these, these are all small steps that help make sure you get coherent responses. 06:51.260 --> 06:54.540 Although as you'll see, it's not going to be perfectly coherent. 06:54.540 --> 06:55.980 But it definitely helps. 06:56.020 --> 06:58.180 And I've experimented with this a fair bit. 06:58.220 --> 07:03.740 And in previous versions, when I was iterating on this, I had inconsistent language between agents 07:03.740 --> 07:07.380 and tasks and definitely causes less stability. 07:07.420 --> 07:09.580 So I think that's a that's a pro tip for you.
