Dungeons & Desktops: Building a procedurally generated roguelike with GitHub Copilot CLI

SMRTR summary

What if your codebase could fight back? A GitHub developer did exactly that, turning his entire code repository into a playable roguelike dungeon, complete with enemies, fog of war, and permadeath.

The project, called GitHub Dungeons, generates a unique dungeon map from any repository using a technique called Binary Space Partitioning, seeded by the latest commit. Change the code, change the dungeon.

What makes this more than a weekend novelty is how it was built. The developer used GitHub Copilot CLI, particularly a command called /delegate, which hands tasks off to an AI coding agent running in the cloud. "Using Copilot is like having an army of NPCs available to do whatever I want them to do," he said.

The result is something oddly poetic: every bug you've ever squashed, every commit you've ever pushed, quietly shaping the labyrinth waiting for you in your terminal.
