Claude Code has deep git integration. You can use slash commands for structured git operations or just describe what you want in natural language.
Committing changes
The /commit command analyzes your staged changes and generates a commit message.
Stage your changes
Use git as normal to stage files:git add src/api/users.ts
git add src/api/auth.ts
Run /commit
Inside the Claude Code REPL:Claude analyzes the diff and proposes a commit message. Confirm or edit
Review the proposed message, edit if needed, then confirm to create the commit.
> Commit my changes with a message that explains I'm adding JWT refresh token support
Viewing diffs
The /diff command shows your current working tree or staged changes:
You can also ask Claude to explain a diff:
> Explain what changed in the last commit
> What does this diff do?
Branch management
Use /branch to create and switch branches:
> /branch feature/add-oauth
> /branch fix/login-timeout
> Create a new branch called feature/user-profiles
> Switch to the main branch
/pr_comments command fetches open review comments from your current GitHub PR:
Claude displays each comment with context and can help you address them:
> Address the PR comment about input validation in the user controller
Worktree isolation
For large refactors, Claude Code supports git worktrees to isolate changes:
> Enter worktree mode for my refactoring task
EnterWorktreeTool to create an isolated git worktree. Exit with ExitWorktreeTool when done.
For complex multi-file changes, stage interactively with git add -p before running /commit so Claude generates a focused, accurate message.
