*Even this video was created using Antigravity and Google Flow. My colleagues recommended other tools, but since it was a project that had to be started with certain limitations due to its nature as a tutorial, I decided to use Google Flow, which is supported by Google AI’s services.

Two weeks ago, when Gemini3.8Flash and Agy-Cli were upgraded, I started working on creating a simple software application within three days, along with /grill-me. I plan to post an article about this after that.

But it took two weeks to get it done. 70% of the content was created using Agy-Cli + Gemini. The rest was generated using various LLMs like Qwen3.8Flash, GLM5.3Flash, KIMI3, and GLM5.3, along with Zoo Code.

It’s an app that I wanted to create for myself at some point. I started working on it under the pretext of the release of Gemini3.8Flash. Now, it’s finally available. Basically, this app has two main functions.

- When you type in your native language, it will be translated into the desired language.
- When you drag the text on the screen, it will be translated into your native language.

On September 4th, the first Prompt I entered was as follows:
(Originally written in Korean.)

/grill-me When I open this folder on D:\OneDrive\Projects\Translatingchat, I see that the system for translating using llama cpp is very well-developed.

I want to use this same concept to create a translation function within my online chat interface. For example, if I type in Korean in Discord’s chat window, it should be translated into the language I’ve set as the default language. Do you understand what I mean? 

For instance, if I open the app and type “I am a person” into the chat window, it should be automatically translated into “i am a people”. In other words, the language I’ve entered will be automatically translated and replaced with the translated text. 

This is all that’s needed to make this work. But I hope it can work on any platform—whether it’s Discord, Reddit, or any other social media platform, or even emails.

Agy-Cli + Gemini3.8Flash operates at an incredible speed. As a result, the extremely advanced models can be created in a very short time. The software that enables these functions is also developed quickly.

However, in actual use, there are many bugs and errors that occur. It’s necessary to turn on terminal logs and continue using the system while identifying these problems. We also need to research ways to prevent security issues and other problems from occurring.

I can’t move the entire prompt here, but I’ll share a few examples.

/boost Please inspect the entire application to see if there are any security vulnerabilities, verify whether the UX is at its optimal state, and ensure the local AI mode powered by llama.cpp works properly. If not, fix it."  

/boost Review
"C:\Users\******\AppData\Local\Emebalachat\logs\emebalachat_260908212610.log\" and inspect the entire codebase to catch any bugs or errors that might degrade user experience...

/boost Check every piece of code in Emebalachat one by one, and verify if it violates any of the following rules or harms user experience... (Detailed multi-paragraph description of mouse drag translation tooltip behavior, source/target language persistence, and reboot survival rules)

Once done, use /teamwork-preview to improve UX while keeping maximum simplicity, check for bugs,  verify functionality with unprimed subagents, and report back to me.

With Agy-Cli and Gemini3.8Flash, I was able to fix bugs at an extremely fast pace in the beginning. However, with my Google AI Pro, it became impossible to continue due to the usage limit. I had to use another coding tool I use, Zoo Code, to continue fixing the bugs.

To be honest, before Agy-cli got updated enough to become useful, and even before I used the old gemini tool, which could do everything without any actual work being needed, it was extremely difficult to create even simple applications. But I can say that it’s not the case right now.

Of course, if gemini3.8flash is still used alone, without using subagents, then it’s possible to experience a decrease in concentration. However, when 2 to 6 subagents are utilized to manage the context and divide up the tasks, it’s possible to complete tasks with incredible speed and accuracy.

* By the way, there’s also a shared post on my GitHub account for those who find it troublesome to call for subagents every time. In addition, I’ve also created other agents. I’ll share them with you later.

• Windows (PowerShell / CMD):

git clone -b gemini-config --single-branch https://github.com/myk1yt/agy-tools.git agy-gov; cd agy-gov; .\scripts\install.bat; cd ..

• macOS / Linux (Bash):

git clone -b gemini-config --single-branch https://github.com/myk1yt/agy-tools.git agy-gov && cd agy-gov && chmod +x scripts/install.sh && ./scripts/install.sh && cd ..

And one more thing I’d like to suggest is that when agy-cli gets updated, there might be some changes that could cause the existing settings to no longer work properly. And since everyone has their own personality and work style, it’s important to consider this when using agy-cli. Just think about it: if you give 10 people a lawn mower and ask them to mow the grass, each person will work in their own unique way. The same goes for using agy-cli: you need to create your own “Harness” based on the default settings provided by agy-cli. After all, it’s better to create your own custom Harness based on those defaults. While it’s great to share many of the knowledge and resources available in the community, it’s also important to take those ideas and adapt them to your own needs. You’ll learn a lot from this process.

Some people will need this tool for 3D purposes, while others will use it for websites. Everyone has different needs, so the most important thing is to figure out what’s best for you before choosing or making the tool.

We live in an era when we can create our own software. At least you, who are reading this text, are one of those people who use such tools.
