A developer used Claude Code in agent mode to build a web version of the Hitori puzzle game. Starting from a Linux C implementation, they set up a Django backend and JavaScript frontend, then prompted the AI to create the full client-server architecture. The developer simply watched the process unfold.

The next morning, the complete game was ready to play. The developer was stunned, having never opened an editor or IDE. They then tasked the AI with adding a login system and deploying the entire stack to a Kubernetes cluster, which also proceeded automatically without manual intervention.

This project marks a first for the developer: building and deploying a full application entirely from the command line. It demonstrates how AI agents can now handle complex, multi-step software development tasks. The finished game is publicly available for play online, showcasing a new frontier in developer productivity tools.
