• At each step,



compare two versions of the assistant's response, choose the better one, and write a brief explanation of your reasoning
• Work in your own environment, on your own schedule, with your own tools

Who You Are

• A developer with a software project you personally own, stored in a git repository
• Comfortable working in the terminal and with git-based workflows
