How to use SpaceXAI's Grok Build

SpaceXAI’s Grok Build is a terminal-based coding agent that uses the Grok 4.6 large language model to read, write, and run commands directly on your codebase, spawning sub-agents for parallel changes. After installing via PowerShell or a shell script, users log in with an X account, then invoke `grok` to explain code, install dependencies, or generate entire web apps from a single prompt. Access depends on the paid Grok plan, while free users face usage limits.
