SpaceXAI Open-Sources Grok Build: The Rust Agent Harness, TUI, and Tool Layer Behind Its Coding CLI

SpaceXAI has open-sourced Grok Build, a terminal-based AI coding agent that understands codebases, edits files, and executes shell commands, under the Apache 2.0 license. The release includes the agent harness, TUI, CLI shell, and developer tooling, and allows for local-first operation with local inference. The source code is now available on GitHub, enabling users to compile and customize the agent for their needs.
