Git Conventional Commits Skill

Professional git commit workflow that enforces best practices and conventions.

Features

• Conventional Commits Format: Categorize commits by type (feat, fix, docs, style, refactor, perf, test, build, ci, chore)
• Message Validation: Adheres to the 7 rules of great git commits:
  • Separate subject from body with a blank line
  • Limit the subject line to 50 characters
  • Capitalize the subject line
  • Do not end the subject line with a period
  • Use the imperative mood in the subject line
  • Wrap the body at 72 characters
  • Use the body to explain what and why vs. how
• Auto-Detection: Intelligently detects commit type based on file changes
• Preview & Confirmation: Shows formatted commit message before committing
• Multi-Language Support: English and Traditional Chinese (繁體中文)

Commit Types

Type	Description
feat	A new feature
fix	A bug fix
docs	Documentation only changes
style	Formatting, white-space, or semi-colon changes (no code meaning change)
refactor	A code change that neither fixes a bug nor adds a feature
perf	Code that improves performance
test	Adding missing tests or correcting existing ones
build	Changes to build-related components or dependencies
ci	Changes to the CI/CD setup
chore	Routine tasks or maintenance

When to Use

Reference this skill when you need to:

• Create a git commit with proper conventional format
• Ensure commit messages follow best practices
• Auto-detect the type of change being committed
• Preview and confirm commit messages before finalizing
• Support multiple commit message languages

Example Usage

# Invoke the skill when you have staged or unstaged changes
# The skill will:

# 1. Analyze git status and changes
#    - Shows what files are modified/added/deleted
#    - Automatically stages appropriate files

# 2. Auto-detect commit type based on changes
#    - feat: New features (new files, new APIs)
#    - fix: Bug fixes (fixes existing functionality)
#    - docs: Documentation changes only
#    - style: Formatting changes (no logic change)
#    - refactor: Code restructuring (no logic change)
#    - perf: Performance optimizations
#    - test: Test additions/fixes
#    - build: Build system/dependency changes
#    - ci: CI/CD configuration changes
#    - chore: Maintenance tasks

# 3. Generate commit message
#    - Subject line: "{type}: {description}" (max 50 chars)
#    - Body (optional): Explains what and why
#    - Follows all 7 rules of great commit messages

# 4. **DISPLAY PREVIEW** - Saves to session temporary directory
#    Location: ~/.copilot/session-state/{session_id}/commit_preview.txt
#    
#    Content (plain text, fully readable):
#    ════════════════════════════════════════════════════════════
#    feat: Add user authentication
#    
#    Implement JWT-based auth system with secure token handling
#    and automatic refresh logic. Prevents users from being logged
#    out unexpectedly during long sessions.
#    
#    ────────────────────────────────────────────────────────────
#    Files: 3 changed | +145 insertions | -8 deletions
#    ════════════════════════════════════════════════════════════
#    
#    Benefits of using session temp directory:
#    - Does NOT pollute your project directory
#    - Will NOT be tracked by git
#    - Automatically cleaned up when session ends

# 5. **REQUEST USER CONFIRMATION**
#    - User is asked: "Please review the commit message in
#      ~/.copilot/session-state/{session_id}/commit_preview.txt
#      Do you want to proceed?"
#    - Mandatory: User must explicitly approve
#    - Options: ✅ Yes, confirm and commit | ❌ No, cancel commit

# 6. **EXECUTE COMMIT** (Only if confirmed)
#    If user approves:
#    git commit -m "feat: Add user authentication" \
#               -m "Implement JWT-based auth system..."
#    
#    If user declines:
#    Commit cancelled by user. (No changes made)

Important: Preview & Confirmation

This skill ALWAYS shows a preview and waits for explicit user confirmation before committing.

This prevents accidental commits and ensures quality control. The preview step is mandatory and cannot be skipped.

Preview File Location: ~/.copilot/session-state/{session_id}/commit_preview.txt

• Automatically cleaned up when session ends
• Not tracked by git
• Easy to find in your session folder

Configuration

• Default Language: English
• Commit Body: Optional (automatically included when explaining "why" for complex changes)
• Message Validation: All messages validated against 7 rules before committing
• Preview Storage: Session temporary directory (not project directory)
