In this lesson, we begin building "Vibe", a CLI application that will generate git commit messages using LLMs. We start by setting up the foundational project structure, including creating a new Go module, initializing a Git repository, and linking it to GitHub using the GitHub CLI. The core of the lesson focuses on integrating Cobra CLI, a popular framework for building command-line applications in Go, and creating our first subcommand called "commit". By the end of this lesson, you'll have a fully initialized Go project with version control configured and a basic CLI structure in place using Cobra. We establish the groundwork for the commit command that will eventually capture staged git changes and send them to an LLM for intelligent commit message generation. This sets us up perfectly for the next lesson, where we'll implement the functionality to obtain staged changes from Git.
