An undocumented `/gboom` game is small, but it shows xAI treating the CLI as a sticky product surface where culture, habit, and tooling converge. [Grok Build](https://docs.x.ai/build/overview), xAI's terminal coding agent, contains an undocumented Doom-like mini-game that opens when a user types `/gboom` inside the interactive CLI, RuntimeWire confirmed in testing on July 10th. The command is a pure Easter egg. It is absent from the public Grok Build overview and settings pages reviewed by RuntimeWire, which document the CLI's core developer workflow: starting an interactive session with `grok` , running headlessly with `grok -p` , switching models with `/model ` , and configuring the terminal UI through `/settings` . xAI's own launch post also points users to `/feedback` for product comments, while focusing the product pitch on planning, code edits, clean diffs, plugins, hooks, skills, MCP servers, headless mode, and parallel subagents. ## Reader comments Conversation for this story loads after sign-in.
