commit-message（提交消息）

Git Commit Message Generator

Generate concise, descriptive Git commit messages in English.

Process

1. Run git diff --cached directly (NOT git -C <path> diff --cached, NOT cd <path> && git diff --cached) to check for staged changes
2. If staged changes exist: generate commit message based on staged changes only
3. If no staged changes: run git diff directly (NOT git -C <path> diff, NOT cd <path> && git diff) and git status directly (NOT git -C <path> status, NOT cd <path> && git status) to view unstaged and untracked files
4. For untracked files, intelligently assess which need content review (code/config files) vs which can be inferred from filename (assets, dependencies)
5. Generate a single-line commit message

Output

Output ONLY the commit message — a single line, no explanation, no follow-up questions, no code block fencing.

Format

• Imperative mood, under 72 characters
• Focus on the 'what' and 'why' of the change, not the 'how'. Avoid generic messages like 'update code' or 'fix bug'.
• No type prefix (e.g., feat:, fix:) unless the user explicitly requests Conventional Commits format
