Writing good commit messages in Git creates clear project history that helps team members understand changes and makes debugging and code reviews more efficient. As the creator of CoreUI, a widely used open-source UI library, I’ve written thousands of commit messages across multiple repositories and established clear messaging standards for enterprise development teams. From my expertise, the most effective approach is using imperative mood with descriptive subjects and optional body text for complex changes. This method provides clear change documentation and improves team collaboration through better communication.
