WEBVTT 1 00:00:00.120 --> 00:00:03.000 So we talked about the Planning Tool 2 00:00:03.000 --> 00:00:04.680 or To-Do List tool, 3 00:00:04.680 --> 00:00:07.680 and let's talk about another characteristic; 4 00:00:07.680 --> 00:00:11.550 and this is the Sub Agents capability. 5 00:00:11.550 --> 00:00:15.900 So Deep Agents employ the idea of Sub Agents, 6 00:00:15.900 --> 00:00:18.510 which are going to enable us have something 7 00:00:18.510 --> 00:00:22.110 which is called hierarchical delegation. 8 00:00:22.110 --> 00:00:25.200 And this means the Deep Agent itself 9 00:00:25.200 --> 00:00:29.850 can spawn and create new instances of itself, 10 00:00:29.850 --> 00:00:34.850 but those instances are going to be specialized Sub Agents 11 00:00:35.670 --> 00:00:37.950 for focused tasks. 12 00:00:37.950 --> 00:00:41.160 So each Sub Agent is going to be holding 13 00:00:41.160 --> 00:00:44.760 its different system prompt, its own description, 14 00:00:44.760 --> 00:00:47.760 its different set of tools it can use. 15 00:00:47.760 --> 00:00:51.060 And this is actually quite genius I have to say, 16 00:00:51.060 --> 00:00:54.300 because this is exactly like we have in real-life. 17 00:00:54.300 --> 00:00:57.210 Whenever we don't feel like doing something 18 00:00:57.210 --> 00:01:01.080 and we want to delegate a task to another, 19 00:01:01.080 --> 00:01:03.660 then we need to make sure that the other person, 20 00:01:03.660 --> 00:01:07.020 he has the correct skills and the correct tools 21 00:01:07.020 --> 00:01:08.370 to achieve that tasks. 22 00:01:08.370 --> 00:01:09.540 But not only that, 23 00:01:09.540 --> 00:01:13.260 we need to know how to explain to that person what to do. 24 00:01:13.260 --> 00:01:16.020 And let me give you an example from the real-world. 25 00:01:16.020 --> 00:01:20.040 So I personally am not a handyman, 26 00:01:20.040 --> 00:01:22.380 I have no craftsmanship, 27 00:01:22.380 --> 00:01:25.860 and I don't know how to drill a hole in the wall, 28 00:01:25.860 --> 00:01:27.960 and I'm really, really bad at this stuff. 29 00:01:27.960 --> 00:01:30.900 And I've had a really annoying issue in my house 30 00:01:30.900 --> 00:01:33.660 where I have this kind of hatch in the ceiling 31 00:01:33.660 --> 00:01:35.340 of my top floor, 32 00:01:35.340 --> 00:01:37.080 and every time it rains, 33 00:01:37.080 --> 00:01:41.940 then what happens is that the rain hits this hatch, 34 00:01:41.940 --> 00:01:45.660 and it's covered with fiberglass or some kind of material, 35 00:01:45.660 --> 00:01:48.240 and it makes a lot of noise. 36 00:01:48.240 --> 00:01:49.980 And when it's pouring raining, 37 00:01:49.980 --> 00:01:51.390 it's really, really noisy 38 00:01:51.390 --> 00:01:54.510 and it echoes through the entire house, 39 00:01:54.510 --> 00:01:56.670 so I really needed to handle this. 40 00:01:56.670 --> 00:02:00.000 And in order to fix it, I bought some synthetic grass 41 00:02:00.000 --> 00:02:02.310 to simply put over the fiberglass, 42 00:02:02.310 --> 00:02:04.170 so that when the rain drops, 43 00:02:04.170 --> 00:02:06.060 it's not going to hit the fiberglass, 44 00:02:06.060 --> 00:02:08.490 it's going to drop on the synthetic grass, 45 00:02:08.490 --> 00:02:11.160 and then it's going to be much less noise. 46 00:02:11.160 --> 00:02:12.450 And the ceiling is pretty high, 47 00:02:12.450 --> 00:02:14.520 and in order to get up to the roof, 48 00:02:14.520 --> 00:02:16.470 you need to have this kind of special ladder 49 00:02:16.470 --> 00:02:18.780 where it needs to open diagonally, 50 00:02:18.780 --> 00:02:20.670 and you can then climb to the roof 51 00:02:20.670 --> 00:02:24.540 and then assemble this piece of synthetic grass. 52 00:02:24.540 --> 00:02:27.600 Anyways, I don't have the skills even to do it. 53 00:02:27.600 --> 00:02:29.970 So what I did is call my father-in-law 54 00:02:29.970 --> 00:02:31.680 who is really good at this stuff. 55 00:02:31.680 --> 00:02:36.510 And he went in with his own tools, he has a box cutter, 56 00:02:36.510 --> 00:02:39.270 which he used to cut the synthetic grass 57 00:02:39.270 --> 00:02:40.950 into the right size, 58 00:02:40.950 --> 00:02:44.250 and he used his own ladder to climb to the ceiling 59 00:02:44.250 --> 00:02:45.900 and to do all of this. 60 00:02:45.900 --> 00:02:47.910 And I think the analogy of a Sub Agent 61 00:02:47.910 --> 00:02:49.260 is really appropriate here 62 00:02:49.260 --> 00:02:52.500 because I had a message that I wrote to him 63 00:02:52.500 --> 00:02:55.290 that I needed help with doing this task. 64 00:02:55.290 --> 00:02:59.220 I described the task, and then he came with his own tools, 65 00:02:59.220 --> 00:03:02.370 and his own "system prompt," which is his skills, 66 00:03:02.370 --> 00:03:04.020 and he knows how to do these things. 67 00:03:04.020 --> 00:03:05.520 He went and did it, 68 00:03:05.520 --> 00:03:07.020 I wasn't even there when he did it, 69 00:03:07.020 --> 00:03:08.520 because he had a key to the house. 70 00:03:08.520 --> 00:03:12.450 And finally the result was I went and everything was fixed. 71 00:03:12.450 --> 00:03:13.890 And when it rains now, 72 00:03:13.890 --> 00:03:16.230 it doesn't echo through my entire home. 73 00:03:16.230 --> 00:03:19.170 And this is really similar to how Sub Agents work. 74 00:03:19.170 --> 00:03:21.450 Now, I want to add on top of that, 75 00:03:21.450 --> 00:03:25.350 that while he was working, I had no idea what's happening. 76 00:03:25.350 --> 00:03:30.000 So as far as context, he was working in context isolation. 77 00:03:30.000 --> 00:03:32.130 I didn't know what was happening, 78 00:03:32.130 --> 00:03:34.233 and I just got the final result. 79 00:03:35.250 --> 00:03:39.750 So let's go back to the discussion on Sub Agents. 80 00:03:39.750 --> 00:03:43.560 The Sub Agents, they're going to do isolated work, 81 00:03:43.560 --> 00:03:45.540 so this means they're going to run 82 00:03:45.540 --> 00:03:47.640 in their own context window 83 00:03:47.640 --> 00:03:51.450 without polluting the main agent's context window, 84 00:03:51.450 --> 00:03:53.940 and they're going to be specialized. 85 00:03:53.940 --> 00:03:57.810 So they can have their own system prompt, their own tools, 86 00:03:57.810 --> 00:04:01.200 which can differ from one Sub Agent to another. 87 00:04:01.200 --> 00:04:05.790 And this gives us the capability to scale our work 88 00:04:05.790 --> 00:04:08.040 and to actually get more quality work 89 00:04:08.040 --> 00:04:10.260 with specialized agents here. 90 00:04:10.260 --> 00:04:12.600 So those Sub Agents are going to execute 91 00:04:12.600 --> 00:04:14.490 on their own tool calling loops, 92 00:04:14.490 --> 00:04:16.980 their own react loops internally, 93 00:04:16.980 --> 00:04:20.580 and they're going to return back only the final response 94 00:04:20.580 --> 00:04:23.160 without those intermediate results. 95 00:04:23.160 --> 00:04:25.560 So this delegation pattern 96 00:04:25.560 --> 00:04:28.770 helps us achieve this context isolation. 97 00:04:28.770 --> 00:04:31.650 And preventing this specialized work 98 00:04:31.650 --> 00:04:34.320 from polluting the main agent's attention, 99 00:04:34.320 --> 00:04:37.350 it's going to enable parallel execution of tasks, 100 00:04:37.350 --> 00:04:40.410 and this is going to dramatically improve the quality 101 00:04:40.410 --> 00:04:43.020 and efficiency and the depth of the results 102 00:04:43.020 --> 00:04:44.790 we can get from our agent. 103 00:04:44.790 --> 00:04:49.080 And let's go back to an example, more techy with cloud code. 104 00:04:49.080 --> 00:04:50.940 And here you can see that cloud code 105 00:04:50.940 --> 00:04:54.840 has found an exploration agent, 106 00:04:54.840 --> 00:04:58.140 which is going to find us authentication patterns, 107 00:04:58.140 --> 00:05:00.180 and it's going to do some searching, 108 00:05:00.180 --> 00:05:03.870 and it's going to run while the main agent is running 109 00:05:03.870 --> 00:05:04.890 as well here. 110 00:05:04.890 --> 00:05:07.740 So the point here is that cloud code 111 00:05:07.740 --> 00:05:10.830 is implementing this kind of architecture as well, 112 00:05:10.830 --> 00:05:13.800 and he has this capability support for Sub Agents, 113 00:05:13.800 --> 00:05:16.500 which is super powerful and super useful. 114 00:05:16.500 --> 00:05:18.900 Now, a quick disclaimer over here. 115 00:05:18.900 --> 00:05:22.350 I know that by now I've been very theoretical, 116 00:05:22.350 --> 00:05:24.000 I've been waving my hands, 117 00:05:24.000 --> 00:05:26.820 and I've only been talking about concepts, 118 00:05:26.820 --> 00:05:28.680 not about implementation. 119 00:05:28.680 --> 00:05:29.760 So, don't worry, 120 00:05:29.760 --> 00:05:32.460 I promise you the implementation part will come, 121 00:05:32.460 --> 00:05:35.940 and we'll see exactly how we can go and implement 122 00:05:35.940 --> 00:05:38.550 all these kinds of beautiful magic here. 123 00:05:38.550 --> 00:05:41.670 But I just want to continue and review the concepts 124 00:05:41.670 --> 00:05:43.110 and the interface 125 00:05:43.110 --> 00:05:46.950 and how those capabilities of Deep Agents are looking 126 00:05:46.950 --> 00:05:49.680 in our day-to-day lives with the common tools 127 00:05:49.680 --> 00:05:50.910 that we use here. 128 00:05:50.910 --> 00:05:54.000 So the implementation part will come soon. 129 00:05:54.000 --> 00:05:55.440 And in the next video, 130 00:05:55.440 --> 00:05:59.160 I want to dive deeper into the context flow 131 00:05:59.160 --> 00:06:00.450 when using Sub Agents, 132 00:06:00.450 --> 00:06:03.540 and I want to show you how using Sub Agents 133 00:06:03.540 --> 00:06:07.260 is going to prevent us from bloating our context 134 00:06:07.260 --> 00:06:09.900 and achieve context isolation, 135 00:06:09.900 --> 00:06:12.063 and eventually better results.
