Git Commit Message Guidelines: Why Write a Clear Commit Message?

Have you ever encountered vague Git commit messages like "modified" or "fixed a bug", making it difficult to review the details of changes? Clear commit messages can solve this problem. They serve as a "diary" for code changes, needing to explain "what was done" and "why it was done". There are four key benefits to writing standardized commit messages: quick recall (understand changes even after half a year), team collaboration (members quickly locate feature changes), automated tool support (generate version logs, automatically upgrade version numbers), and rapid bug localization (use `git bisect` to quickly narrow down issues during production problems). Start with simplicity for standardization: at minimum, include a "type + description". Common types include `fix` (bug fixes) and `feat` (new features). For advanced usage, consider the Conventional Commits specification, with the format `<type>[optional scope]: <description>`, which can include a body and footer. Beginners can start with "type + description" and use tools like `cz-cli` for assistance. Spend 10 seconds clarifying the core content before each commit, and consistency will improve code management efficiency.
