Example of Claude Code Git Integration

A developer shared a bash script that integrates Claude Code with GitHub Issues, enabling automated local processing of issue commands. The script creates a branch, sets up a Node.js environment, and uses the GitHub CLI to comment on issues, demonstrating a practical workflow for AI-assisted development.
