WEBVTT 00:00.440 --> 00:06.920 Okay, now there's something a bit confusing now, which I'll have to get your head around, which is 00:06.920 --> 00:12.240 that you can, as we've just done, turn a function into a tool. 00:12.640 --> 00:15.280 There's something else you can turn into a tool as well. 00:15.480 --> 00:18.680 You can turn a whole agent into a tool. 00:18.920 --> 00:24.880 You can say, we've got this sales agent, something that can write a sales email. 00:25.080 --> 00:30.440 Well, that whole thing, that whole process of calling that LM with that prompt, that can just be 00:30.440 --> 00:32.560 considered itself to be a tool. 00:32.560 --> 00:35.720 We can think of it as a sales agent tool. 00:36.240 --> 00:42.040 And doing that might sound like there's a fair amount of work to be done to package an LM call into 00:42.040 --> 00:42.640 a tool. 00:43.000 --> 00:51.200 But no, all you have to do is call as tool on the agent, and you will convert the agent into a tool. 00:51.680 --> 00:54.600 What does it mean to convert an agent into a tool? 00:54.840 --> 00:58.200 All it means is it's going to create a new tool. 00:58.200 --> 01:02.080 It's going to have all of the JSON gunk that describes what that tool can do. 01:02.280 --> 01:07.560 And if that tool is called it's going to actually call the agent and make the agent make the call to 01:07.560 --> 01:08.160 the LM. 01:08.320 --> 01:13.920 So it's a wrapper, a wrapper around the agent that turns the agent into a tool. 01:14.160 --> 01:15.360 That's all it is. 01:15.360 --> 01:16.640 So let's look at this. 01:16.680 --> 01:18.640 Sales agent one as tool. 01:18.640 --> 01:25.320 We're going to give it a tool name sales agent one still and write a cold sales email is our description 01:25.320 --> 01:26.600 of what that tool can do. 01:26.720 --> 01:30.560 And now if we look at tool one you can see it's a function tool just like this one. 01:30.560 --> 01:31.760 Just like send email. 01:32.040 --> 01:33.080 It's got a different name. 01:33.120 --> 01:35.160 Its description is this description here. 01:35.200 --> 01:40.200 Now it's got the same like parameters, the JSON blob that we would expect. 01:40.560 --> 01:46.240 And it's got a special function to tell it what to do when the tool is actually called. 01:46.240 --> 01:49.200 And that of course is actually going to call our agent. 01:49.640 --> 01:51.760 So hopefully that makes sense. 01:51.760 --> 01:55.440 We're now going to package our agents into tools and use them. 01:56.120 --> 01:58.040 All right here we go. 01:58.360 --> 02:04.320 So this I could have done this with a fancy loop, but I thought, you know what, I'll just spell it 02:04.320 --> 02:07.320 out so that you're crystal clear on what's happening here. 02:07.960 --> 02:09.690 We're going to have three tools. 02:09.730 --> 02:10.530 Tool one. 02:10.570 --> 02:12.250 Tool two and tool three. 02:12.490 --> 02:14.970 And it is just taking the three agents. 02:15.050 --> 02:17.690 Sales agent one, two and three. 02:17.850 --> 02:20.490 And calling as tool on each of them. 02:20.810 --> 02:26.970 And for each one we just give it a tool name and a tool description which is the same tool description. 02:27.570 --> 02:28.850 That is it. 02:28.890 --> 02:34.170 Now if you if you feel up to it, just rewrite that as a nice little loop so that we don't have a silliness 02:34.410 --> 02:36.290 with the repetition like this. 02:36.290 --> 02:38.210 But but I wanted to spell it out. 02:38.250 --> 02:45.450 And now I'm giving myself a list called tools and tools has tool one, tool two, tool three. 02:45.450 --> 02:48.490 And these are like the agents wrapped as tools. 02:48.490 --> 02:54.810 They're tools that would simply call the agents and then send email is the real tool that is just a 02:54.810 --> 02:55.450 function. 02:55.490 --> 02:58.810 Send email that calls SendGrid the email program. 02:59.130 --> 03:01.530 And let's have a look at what we get if we run this. 03:01.530 --> 03:03.250 So now this is our list of tools. 03:03.250 --> 03:09.210 And it is indeed four function tools sales agent one, sales agent two, sales agent three and send 03:09.250 --> 03:12.170 email all in a list of tools. 03:12.850 --> 03:18.650 Okay, now it's time to put all of that into a sales manager. 03:18.970 --> 03:20.530 Our planning agent. 03:20.810 --> 03:27.810 So now it's a bit like we did before, except we're giving an agent the ability to choose what to run 03:27.810 --> 03:28.290 when. 03:28.330 --> 03:33.450 It's not like we're just writing Python code to say, do this, this, this, and then send email. 03:33.450 --> 03:40.770 But rather we're letting the agent decide you are a sales manager working for comply. 03:41.130 --> 03:45.370 You use the tools given to you to generate cold sales emails. 03:45.570 --> 03:47.490 You never generate sales emails yourself. 03:47.530 --> 03:49.010 You always use the tools. 03:49.290 --> 03:52.930 You try all three tools once before choosing the best. 03:52.970 --> 04:00.810 You pick the single best email and use the Send Email tool to send the best email and only the best 04:00.810 --> 04:02.250 email to the user. 04:02.290 --> 04:04.450 Now, I'm probably over spelling it out here. 04:04.450 --> 04:05.330 You can experiment. 04:05.330 --> 04:10.290 It's not always required to be so pedantic, but I'm also doing it to show you what's going on. 04:10.610 --> 04:14.810 And it's never a bad thing to be very precise and instructive with your prompts. 04:15.530 --> 04:20.890 Okay, so with that, we want to create a new sales manager agent. 04:20.970 --> 04:21.810 There it is. 04:21.850 --> 04:24.130 We want to give it these instructions. 04:24.170 --> 04:25.290 It's system prompt. 04:25.330 --> 04:27.530 We want to pass in all four tools. 04:27.530 --> 04:28.930 All these tools right here. 04:29.290 --> 04:30.890 And we give it a model. 04:31.730 --> 04:36.250 And then we say send a cold sales email addressed to dear CEO. 04:36.770 --> 04:42.170 And we start this going and off it runs. 04:42.370 --> 04:44.730 And this will take about 30s. 04:44.730 --> 04:46.410 So I will see you in a seconds. 04:46.930 --> 04:48.330 Well actually it didn't take 30s. 04:48.330 --> 04:49.370 It took 18 seconds. 04:49.370 --> 04:50.290 So it's quite quick. 04:50.490 --> 04:51.530 And it finished. 04:51.810 --> 04:57.810 And we can first let's look look in my email I did in fact just receive an email and here it is. 04:58.210 --> 04:59.610 And very good. 04:59.810 --> 05:03.010 It does indeed do things quite nicely. 05:03.010 --> 05:03.370 You'll see. 05:03.370 --> 05:09.290 It's put like like a template CEO's name not dear CEO you can improve the prompting to stop it doing 05:09.290 --> 05:13.370 that if you wish, but there's an exercise at the end to incorporate mail merge. 05:13.370 --> 05:16.410 So it actually would put in real people's names here. 05:16.690 --> 05:17.850 But but very nice. 05:17.850 --> 05:24.340 We got the email, it came through to me and it came from the verified email sender as expected. 05:24.700 --> 05:27.540 The other thing to do, of course, is to go and have a look at the trace. 05:27.540 --> 05:28.860 Let's go and do that now. 05:29.140 --> 05:29.820 So here it is. 05:29.820 --> 05:31.980 Sales manager is what we called it for. 05:31.980 --> 05:33.220 Tools were used. 05:33.220 --> 05:34.300 It took 18 seconds. 05:34.300 --> 05:35.460 Let's go in and have a look. 05:35.740 --> 05:37.260 So it called Sales Agent one. 05:37.300 --> 05:38.620 It called sales agent two. 05:38.780 --> 05:39.980 Sales agent three. 05:39.980 --> 05:42.460 And then it called Send Email. 05:42.460 --> 05:45.340 That's the the the tool that is just a tool. 05:45.660 --> 05:51.660 If you look at each of these sales agents tools representing by this this sort of green thing, you'll 05:51.660 --> 05:54.140 see that underneath that was an agent. 05:54.140 --> 05:59.340 So this hopefully makes it crystal clear for you that we had an agent, the professional sales agent 05:59.340 --> 06:02.740 that was wrapped in the tool, sales agent one. 06:02.740 --> 06:04.980 And you can see that again for this one and for this one. 06:04.980 --> 06:10.940 But in the case of send email, it was simply a function that was called with a body. 06:10.940 --> 06:16.180 But you can look through the trace and you should look through the trace and understand the interactions 06:16.180 --> 06:24.020 between tools and agents to allow the sales manager to carry out its full activity, allowing itself 06:24.020 --> 06:26.940 to make its decisions about what it does, in what order.
