Uh hello guys in this live stream I will
0:05
actually show you Gemini has released a
0:07
new update in the CLI version which is
0:10
called as
0:13
agents.
0:15
So inside the CLI mode they have
0:17
released this agent mode. It's called as
0:20
agent skills. If you directly type this
0:22
on Google the very first result which
0:24
comes. So this agent port directly lives
0:29
inside your terminal.
0:32
So it can actually do a lot of things
0:34
for you. You can also create custom
0:37
agents as well.
0:40
So first of all simply directly install
0:42
CLI Gemini CLI which is completely free
0:46
to install. I've already installed it.
0:49
So
0:51
now to activate this you simply type on
0:53
the terminal Gemini. And now the
0:55
terminal will directly open.
1:03
So from the terminal right here to
1:06
actually activate this mode you simply
1:09
type uh
1:13
so yeah this is
1:17
the agent skills mode right here.
1:23
So you just need to activate this
1:25
command which is slash
1:27
skills. So if you type this, this will
1:30
enable this list enable or disable
1:34
reload Gemini CLA agent skills mode. So
1:37
simply type in the terminal /kills to
1:40
activate this. So once you click enter,
1:44
you will see all these skills which are
1:47
available for you.
1:51
So first of all we have code review. So
1:53
if you want to do code review you can
1:55
use this agent cross review in it when
2:00
user ask to initialize a repo create
2:02
agents. You also have Microsoft foundry
2:06
pinaco plan out research.
2:10
These are some of the skills which are
2:13
there for you.
2:16
So you can simply type here init.
2:24
So it initializes the project and
2:27
creates a tailored gemini.mmarkdown
2:29
file. So as you s simply type this you
2:32
will see as it will now analyze the
2:36
project and create this gemini markdown
2:38
file for you.
2:41
So this is this agent mode which is
2:43
really insane. it make use of these
2:46
built-in agents. It you can see it is
2:48
reading on this project file all the
2:50
files and based upon the configuration
2:53
it will create a markdown file which
2:57
will be useful for the AI to understand
2:59
the actual project which is there. So it
3:02
created this Gemini markdown file as you
3:04
see that
3:11
it will read all the files and actually
3:14
think about the project.
3:19
So
3:21
based upon that it will create and
3:23
populate this gemini.mmarkdown file. So
3:27
this is one agent and similarly you have
3:30
different agents as well. You can even
3:32
create your custom agents as well by
3:37
enabling disabling everything.
3:48
So you grant the permission right here
3:50
for writing this file. So now it
3:52
successfully written this
3:54
gemini.mmarkdown file based upon the
3:56
project here. So it's kind of a react
3:59
application which converts your images
4:00
to PDF. So based upon that it created
4:03
this markdown file
4:06
based upon all the technologies which
4:08
are used the directory structure you
4:11
will see how to run this application. So
4:14
these markdown files are really helpful
4:17
for the AI to actually create
4:20
applications. So
4:23
you can run this skill on any project to
4:25
create a markdown file. So similarly if
4:29
you want to see more skills you simply
4:31
type slash
4:35
and similarly you have agents as well.
4:38
So you simply
4:41
these are different agents which are
4:43
there.
4:48
So if you want to analyze anything
4:52
in the codebase you simply run this
4:55
agent which is code base.
4:58
So you have code review agent which will
5:08
so similarly you have different agents
5:10
you have different skills you can
5:12
activate this by simply typing slash
5:15
skills. it will list out all the skills
5:19
which are already there and from these
5:21
skills you can actually initiate. So
5:24
let's suppose I want to review the code.
5:26
So I simply type here code review. So
5:30
now the skill will be activated and
5:34
if you ask anything you will say please
5:37
review this
5:39
project. So as soon as you do this now
5:42
the AI will start reviewing this
5:44
project.
6:09
So you can see it is generating this
6:11
full code review of this project.
6:19
So these this mode is really helpful.
6:21
Definitely check this out.
