Commit Message Standards

This skill ensures consistent, meaningful commit messages following conventional commits.

Quick Reference

Basic Format

<type>(<scope>): <subject>

<body>

<footer>

Commit Types

English	中文	When to Use
`feat`	`新增`	New feature
`fix`	`修正`	Bug fix
`refactor`	`重構`	Code refactoring (no functional change)
`docs`	`文件`	Documentation only
`style`	`樣式`	Formatting (no code logic change)
`test`	`測試`	Adding or updating tests
`perf`	`效能`	Performance improvement
`build`	`建置`	Build system or dependencies
`ci`	`整合`	CI/CD pipeline changes
`chore`	`維護`	Maintenance tasks
`revert`	`回退`	Revert previous commit
`security`	`安全`	Security vulnerability fix

Subject Line Rules

Length: ≤72 characters (50 ideal)
Tense: Imperative mood ("Add feature" not "Added feature")
Capitalization: First letter capitalized
No period: Don't end with a period

Detailed Guidelines

For complete standards, see:

Examples

✅ Good Examples (English)

feat(auth): Add OAuth2 Google login support
fix(api): Resolve memory leak in user session cache
refactor(database): Extract query builder to separate class
docs(readme): Update installation instructions for Node 20

✅ Good Examples (中文)

新增(認證): 實作 OAuth2 Google 登入支援
修正(API): 解決使用者 session 快取記憶體洩漏
重構(資料庫): 提取查詢建構器為獨立類別

✅ Good Example (Bilingual)

feat(auth): Add OAuth2 Google login support. 新增 OAuth2 Google 登入支援。

Implement Google OAuth2 authentication flow for user login.

實作 Google OAuth2 認證流程供使用者登入。

Closes #123

❌ Bad Examples

fixed bug                    # Too vague, no scope
feat(auth): added google login  # Past tense
Update stuff.                # Period, vague
WIP                          # Not descriptive

Body Guidelines

Use the body to explain WHY the change was made:

fix(api): Resolve race condition in concurrent user updates

Why this occurred:
- Two simultaneous PUT requests could overwrite each other
- No optimistic locking implemented

What this fix does:
- Add version field to User model
- Return 409 Conflict if version mismatch

Fixes #789

Breaking Changes

Always document breaking changes in footer:

feat(api): Change user endpoint response format

BREAKING CHANGE: User API response format changed

Migration guide:
1. Update API clients to remove .data wrapper
2. Use created_at instead of createdAt

Configuration Detection

This skill supports project-specific language configuration.

Detection Order

Check CONTRIBUTING.md for "Commit Message Language" section
If found, use the specified option (English / Traditional Chinese / Bilingual)
If not found, default to English for maximum tool compatibility

First-Time Setup

If no configuration found and context is unclear:

Ask the user: "This project hasn't configured commit message language preference. Which option would you like to use? (English / 中文 / Bilingual)"
After user selection, suggest documenting in CONTRIBUTING.md:

## Commit Message Language

This project uses **[chosen option]** commit types.
<!-- Options: English | Traditional Chinese | Bilingual -->

Configuration Example

In project's CONTRIBUTING.md:

## Commit Message Language

This project uses **English** commit types.

### Allowed Types
feat, fix, refactor, docs, style, test, perf, build, ci, chore, revert, security
