Version Control & Git Mastery

Transform your Git workflow with Claude Code’s intelligent version control capabilities. From writing perfect commit messages to handling complex merge conflicts, Claude acts as your Git expert, making version control conversational and error-free.

What Claude Can Do

Claude handles 90%+ of Git operations through natural language:

  • Understand changes: Analyze diffs and explain what changed
  • Write commits: Generate context-aware commit messages
  • Manage branches: Create, switch, merge, and clean up branches
  • Handle conflicts: Resolve merge conflicts intelligently
  • Search history: Find commits, blame lines, understand evolution
  • Create PRs: Generate comprehensive pull request descriptions

Start with understanding your current state:

Terminal window
> What files have I changed?
> Show me the diff for the authentication module
> What's the status of my repository?
> Have I modified any test files?

Claude will run git status, git diff, and other commands to give you a clear picture.

Terminal window
> Commit my changes with a descriptive message

Claude will:

  1. Check git status to see what’s changed
  2. Analyze the diff to understand the changes
  3. Generate a conventional commit message
  4. Ask for your approval before committing

Claude writes commit messages that follow best practices:

Claude's Commit Message Format

feat(auth): implement OAuth2 login flow
- Add Google OAuth provider configuration
- Create callback handler for OAuth responses
- Update user model to store OAuth tokens
- Add error handling for failed authentications
Closes #123
Terminal window
> Create a new feature branch for the payment integration
> Switch to the development branch
> Create a hotfix branch from main for the login bug

Claude understands branch naming conventions and will suggest appropriate names:

  • feature/payment-integration
  • hotfix/login-validation
  • bugfix/user-profile-error
  1. List and analyze branches

    Terminal window
    > Show me all branches and which ones can be deleted
    > Which branches have been merged already?
  2. Clean up branches

    Terminal window
    > Delete all branches that have been merged to main
    > Clean up old feature branches
  3. Compare branches

    Terminal window
    > What's the difference between main and develop?
    > Show me commits in this branch that aren't in main

When conflicts arise, Claude becomes invaluable:

Terminal window
> Help me resolve these merge conflicts
> The merge conflict in AuthService.ts is confusing, explain it
> Resolve conflicts favoring the feature branch changes

Claude's Conflict Resolution Process

  1. Analyzes both versions to understand the intent
  2. Explains the conflict in plain English
  3. Suggests resolution based on code logic
  4. Preserves important changes from both branches
  5. Maintains code consistency with project style
Terminal window
> Clean up the last 5 commits with interactive rebase
> Squash all the "WIP" commits into meaningful commits
> Reorder commits so database migrations come first

Claude will:

  • Guide you through the rebase process
  • Suggest which commits to squash
  • Help write better commit messages
  • Handle any conflicts that arise
Terminal window
> Cherry-pick the authentication fix from the develop branch
> Find the commit that introduced the bug in user.service.ts
> Show me who last modified the payment processing code
Terminal window
> Create a pull request for this feature branch

Claude will:

  1. Push the branch to remote
  2. Generate a comprehensive PR description
  3. Include all relevant changes
  4. Link related issues
  5. Add testing instructions

Claude generates PR descriptions like:

## Summary

Enable deeper GitHub integration:

Terminal window
> /install-github-app

This allows Claude to:

  • Automatically review PRs
  • Respond to PR comments
  • Create issues
  • Manage project boards
Terminal window
> Show me all open issues labeled 'bug'
> Create an issue for the performance problem we found
> Assign issue #789 to me and add it to the sprint

With the GitHub App installed, Claude can:

  • Review code changes
  • Suggest improvements
  • Find potential bugs
  • Check for security issues
  • Ensure style consistency
  1. Start new feature

    Terminal window
    > Create a feature branch for user notifications
  2. Develop iteratively

    Terminal window
    > Commit the notification model changes
    > Now commit the UI components
  3. Stay updated

    Terminal window
    > Sync my branch with the latest main
  4. Prepare for merge

    Terminal window
    > Clean up commits and create a PR
Terminal window
# Quick hotfix process
> We have a critical bug in production. Create a hotfix branch
> Fix the authentication timeout issue
> Commit and create an urgent PR
> After merge, update develop with the hotfix

For multiple simultaneous tasks:

Terminal window
> Set up a worktree for the payment feature
> Create another worktree for the urgent bugfix

Worktree Benefits

  • Work on multiple branches simultaneously
  • No need to stash changes
  • Separate Claude instances per worktree
  • Clean context switching
  • Shared Git history
Terminal window
# Create worktree
> git worktree add ../project-payments feature/payments
# List worktrees
> Show me all active worktrees
# Clean up
> Remove the completed feature worktree
Terminal window
> How has the authentication system evolved over time?
> Show me major changes to the API in the last month
> Who has been working on the payment module?
Terminal window
> When was OAuth support added?
> Find commits related to performance improvements
> What changed in version 2.1.0?

Git Excellence with Claude

Always review Claude’s commits before pushing

Keep CLAUDE.md updated with commit conventions
