WEBVTT 00:00:00.500 --> 00:00:04.160 So Agent mode is the default mode that's typically 00:00:04.200 --> 00:00:07.330 selected when you open a new chat, at least at the point of time where I'm 00:00:07.360 --> 00:00:11.340 recording this. And Agent mode is basically an enhanced version of the 00:00:11.380 --> 00:00:15.340 mode because in this mode, it'll not just analyze your code 00:00:15.380 --> 00:00:18.780 and answer questions, but instead, it will also 00:00:18.880 --> 00:00:22.720 actively edit your code. You can always revert those changes and 00:00:22.760 --> 00:00:26.720 you'll see in detail what was changed, but it will make 00:00:26.780 --> 00:00:30.700 changes. So if I open a new chat by clicking the 00:00:30.740 --> 00:00:34.580 plus here or using the shortcut, and I say analyze 00:00:34.620 --> 00:00:38.050 this demo.py file and identify 00:00:38.300 --> 00:00:42.050 potential improvements, despite my 00:00:42.200 --> 00:00:45.980 prompt, it will actually not just identify 00:00:46.080 --> 00:00:49.800 also try to implement them because that's implied if you're in Agent 00:00:49.880 --> 00:00:52.980 mode, that you wanna make changes to your code. 00:00:52.990 --> 00:00:56.040 And of course, I could have therefore also worded this 00:00:56.140 --> 00:00:58.610 about my intent and say, "Analyze this demo file, 00:00:58.640 --> 00:01:02.300 identify potential improvements, and 00:01:02.520 --> 00:01:05.459 implement those improvements." But that's technically not needed. 00:01:05.580 --> 00:01:08.840 You just still might wanna do this to be very sure that it will 00:01:08.960 --> 00:01:12.780 actually edit your code. You 00:01:12.840 --> 00:01:16.690 could also include more detailed instructions like, "Keep the 00:01:16.880 --> 00:01:20.360 overall code clean and simple and avoid 00:01:20.620 --> 00:01:24.300 unnecessary abstractions." Because depending on your 00:01:24.340 --> 00:01:28.140 project and the kind of change you're requesting, the AI might wander 00:01:28.220 --> 00:01:32.100 off and come up with unnecessary complex solutions, so 00:01:32.120 --> 00:01:35.720 adding extra instructions or constraints like this can make sense. 00:01:35.740 --> 00:01:38.580 But I'll get back to my cursor prompting guide a little bit later 00:01:38.640 --> 00:01:41.740 anyways. So for now, I'll just hit enter. 00:01:41.800 --> 00:01:45.100 Again, it'll find this file because it knows 00:01:45.140 --> 00:01:48.910 It analyzes this file, it reads it, it then thinks about it, 00:01:48.940 --> 00:01:52.900 and then it goes ahead, makes a plan, and will then also 00:01:52.980 --> 00:01:56.840 edit the code. So here we go. It's now editing demo.py as you 00:01:56.860 --> 00:02:00.680 can see here. And then once it's done, if I shrink 00:02:00.800 --> 00:02:03.720 that, well, it's not fully done yet. Now it's done. 00:02:03.760 --> 00:02:07.580 It gives me a summary here telling me what it did, so which 00:02:07.640 --> 00:02:10.460 improvements were implemented through which I can read. 00:02:10.650 --> 00:02:14.300 But as you see here in the code file, there's a lot of red and 00:02:14.380 --> 00:02:18.120 green here because it will actually show you what was 00:02:18.160 --> 00:02:21.900 removed, this code was removed, for example, and what was 00:02:22.000 --> 00:02:25.200 added. So in this case, it removed the old 00:02:25.240 --> 00:02:29.030 function and replaced it with a new one that has a 00:02:29.100 --> 00:02:32.780 comment here and that most importantly has error 00:02:32.920 --> 00:02:36.260 handling, handling file-related errors. 00:02:36.269 --> 00:02:39.340 And it added something like this to all these functions. 00:02:39.360 --> 00:02:43.240 It also added a main function then to give me a nice menu 00:02:43.300 --> 00:02:46.620 which allows me to choose which option I wanna go for, write, 00:02:46.660 --> 00:02:50.420 append, and edit the code for executing this main 00:02:50.500 --> 00:02:54.440 execute this file. And what you can do now in this mode 00:02:54.480 --> 00:02:58.260 go through these changes either by scrolling or by clicking 00:02:58.280 --> 00:03:02.000 these arrows here. That will get you to the right 00:03:02.040 --> 00:03:06.000 place. And then for each change, you can undo it or 00:03:06.240 --> 00:03:07.940 keep it, depending on what you wanna do. 00:03:08.020 --> 00:03:11.780 Or you can keep them all or undo them 00:03:11.800 --> 00:03:15.780 all. You can also make edits here. So if I want to add 00:03:15.820 --> 00:03:19.600 a third parameter here, like the mode, which by default should be 00:03:19.820 --> 00:03:21.740 W for write, for example, I can do that. 00:03:21.760 --> 00:03:25.460 You can edit this and if you would click keep now, your 00:03:25.560 --> 00:03:29.380 edit is also kept. So you can make edits 00:03:29.460 --> 00:03:33.360 to these suggested changes. You don't just have to either accept or 00:03:33.380 --> 00:03:36.230 reject them, you can tweak them as well. 00:03:36.280 --> 00:03:38.690 That's very important and that's something many people miss. 00:03:39.480 --> 00:03:43.080 Now here I'll get rid of the mode, therefore this brings me back into this 00:03:43.140 --> 00:03:46.520 mode, but I'll still keep this. Now this adjusted 00:03:46.680 --> 00:03:50.560 originally suggested version. But I don't wanna do this for all these 00:03:50.640 --> 00:03:54.440 blocks. I'm happy with the overall changes, 00:03:54.520 --> 00:03:58.200 here or also here. Keep 00:03:58.280 --> 00:04:02.120 all, undo all. The difference is that certain 00:04:02.180 --> 00:04:05.780 changes might affect multiple files. 00:04:05.840 --> 00:04:09.670 Here, it's all just in one file, but later we'll see examples 00:04:09.720 --> 00:04:13.380 with multiple files and then here you would be undoing or 00:04:13.440 --> 00:04:16.630 accepting for that one file in which you currently are. 00:04:16.660 --> 00:04:20.540 Whereas here on the right, you always undo or accept changes for 00:04:20.660 --> 00:04:23.980 all the files that were added. But here it's only one file, so it's the 00:04:24.040 --> 00:04:27.940 same. Therefore, I'll accept all the changes for all files 00:04:27.980 --> 00:04:31.780 clicking this button over here.
