Git Workflow Guide

This skill provides guidance on Git branching strategies, branch naming conventions, and merge operations.

Quick Reference

Workflow Strategy Selection

Deployment Frequency	Recommended Strategy
Multiple times/day	Trunk-Based Development
Weekly to bi-weekly	GitHub Flow
Monthly or longer	GitFlow

Branch Naming Convention

<type>/<short-description>

Type	Usage	Example
feature/	New functionality	feature/oauth-login
fix/ or bugfix/	Bug fixes	fix/memory-leak
hotfix/	Urgent production fixes	hotfix/security-patch
refactor/	Code refactoring	refactor/extract-service
docs/	Documentation only	docs/api-reference
test/	Test additions	test/integration-tests
chore/	Maintenance tasks	chore/update-dependencies
release/	Release preparation	release/v1.2.0

Naming Rules

1. Use lowercase | 使用小寫
2. Use hyphens for spaces | 使用連字號分隔單詞
3. Be descriptive but concise | 具描述性但簡潔

Detailed Guidelines

• Git Workflow Strategies
• Branch Naming Reference

Pre-branch Checklist

Before creating a new branch:

1. Check for unmerged branches

   git branch --no-merged main
   

2. Sync latest code

   git checkout main
   git pull origin main
   

3. Verify tests pass

   npm test  # or your project's test command
   

4. Create branch with proper naming

   git checkout -b feature/description
   

Merge Strategy Quick Guide

Strategy	When to Use
Merge Commit (--no-ff)	Long-lived features, GitFlow releases
Squash Merge	Feature branches, clean history
Rebase + FF	Trunk-Based, short-lived branches

Examples

Creating a Feature Branch

# Good
git checkout -b feature/user-authentication
git checkout -b fix/null-pointer-in-payment
git checkout -b hotfix/critical-data-loss

# Bad
git checkout -b 123              # Not descriptive
git checkout -b Fix-Bug          # Not lowercase
git checkout -b myFeature        # No type prefix

Merge Workflow (GitHub Flow)

# 1. Create branch from main
git checkout main
git pull origin main
git checkout -b feature/user-profile

# 2. Make changes and commit
git add .
git commit -m "feat(profile): add avatar upload"
git push -u origin feature/user-profile

# 3. Create PR and merge via GitHub/GitLab UI

# 4. Delete branch after merge
git checkout main
git pull origin main
git branch -d feature/user-profile

Handling Merge Conflicts

# 1. Update your branch with main
git checkout feature/my-feature
git fetch origin
git merge origin/main

# 2. Resolve conflicts in files
# <<<<<<< HEAD
# Your changes
# =======
# Incoming changes
# >>>>>>> origin/main

# 3. Stage resolved files
git add resolved-file.js

# 4. Complete merge
git commit -m "chore: resolve merge conflicts with main"

# 5. Test and push
npm test
git push origin feature/my-feature

Configuration Detection

This skill supports project-specific workflow configuration.

Detection Order

1. Check CONTRIBUTING.md for "Git Workflow" or "Branching Strategy" section
2. If found, use the specified strategy (GitFlow / GitHub Flow / Trunk-Based)
3. If not found, default to GitHub Flow for simplicity

First-Time Setup

If no configuration found:

1. Ask the user: "This project hasn't configured a Git workflow strategy. Which would you prefer? (GitFlow / GitHub Flow / Trunk-Based)"
2. After selection, suggest documenting in CONTRIBUTING.md:

## Git Workflow

### Branching Strategy
This project uses **[chosen option]**.

### Branch Naming
Format: `<type>/<description>`
Example: `feature/oauth-login`, `fix/memory-leak`

### Merge Strategy
- Feature branches: **[Squash / Merge commit / Rebase]**
