Overview

This was a vibe coding test using the Gemini CLI to create a Tic-Tac-Toe game in Svelte. The game is designed to be played against an AI opponent, or another local player, with the computer using a simple algorithm to make its moves.

I did not write any code in order to make this app work, neither did I run a single command in the terminal. This project was entirely created using the Gemini CLI, which generated all the necessary files and code based on the prompts provided.

[!NOTE] I did make two additional commits to deploy the project to GitHub Pages. I should have done this before the final commit, but I forgot to do so.

Gemini CLI Usage

After Creating the app using the prompts below, this was the CLI summary of the usage of the Gemini CLI:
