Grok Build Is Now Open Source: What Developers Can Learn from Its Coding-Agent Architecture

Short summary

SpaceXAI has open-sourced Grok Build, a terminal-based coding agent written in Rust, exposing the full agent loop, tool dispatch system, terminal UI, and extension architecture. The repository serves as a reference for how context assembly, model response parsing, and tool execution work in production coding agents. Developers can compile it locally and configure it for local inference.

• •Grok Build's full Rust source is now public on GitHub including agent loop, tools, and TUI
• •Architecture supports skills, plugins, hooks, MCP servers, and subagents
• •Valuable as a reference for building internal developer agents even without switching tools
