## Introduction
Grok Build is an open-source coding agent harness developed by xAI (SpaceXAI). It provides a fullscreen, mouse-interactive terminal UI for running AI-powered coding workflows, with an extensible plugin system for custom tooling and integrations.

## What Grok Build Does
- Provides a fullscreen TUI for interactive agentic coding sessions
- Supports mouse interactions for navigating code, diffs, and file trees
- Offers an extensible architecture for adding custom tools and plugins
- Manages multi-file editing workflows with context-aware suggestions
- Integrates with multiple LLM providers for code generation and review

## Architecture Overview
Grok Build is written in Rust for performance and reliability. It uses a modular harness architecture where the core event loop manages terminal rendering, input handling, and agent orchestration. The plugin system allows extending capabilities without modifying the core binary.

## Self-Hosting & Configuration
- Install from source with `cargo install grok-build` or use prebuilt binaries
- Configure via `~/.config/grok-build/config.toml`
- Set your preferred LLM provider and API key in the config
- Customize keybindings and TUI themes
- Supports project-level config files for team settings

## Key Features
- Fullscreen terminal UI with mouse support
- Extensible plugin architecture for custom tools
- Multi-file editing with inline diffs
- Session persistence and replay
- Built in Rust for fast startup and low memory usage
