Grok Build is SpaceXAI's terminal-based AI coding agent. It runs as a full-screen TUI that understands your codebase, edits files, executes shell commands, searches the web, and manages long-running tasks — interactively, headlessly for scripting/CI, or embedded in editors via the Agent Client Protocol (ACP).

Learn more about Grok Build at x.ai/cli This repository contains the Rust source for the grok CLI/TUI and its agent runtime. It is synced periodically from the SpaceXAI monorepo.

Installing the released binary Prebuilt binaries are published for macOS, Linux, and Windows: curl -fsSL https://x.ai/cli/install.sh | bash # macOS / Linux / Git Bash irm https://x.ai/cli/install.ps1 | iex # Windows PowerShell grok --version See the changelog for the latest fixes, features, and improvements in each release. Building from source Requirements:

Rust — the toolchain is pinned by rust-toolchain.toml; rustup installs it automatically on first build. protoc — proto codegen resolves bin/protoc (a dotslash launcher) or falls back to a protoc on PATH / $PROTOC. macOS and Linux are supported build hosts; Windows builds are best-effort and not currently tested from this tree.

cargo run -p xai-grok-pager-bin # build + launch the TUI cargo build -p xai-grok-pager-bin --release # release binary: target/release/xai-grok-pager cargo check -p xai-grok-pager-bin # fast validation The binary artifact is named xai-grok-pager; official installs ship it as grok. On first launch it opens your browser to authenticate — see the authentication guide. Documentation Full online documentation is available at docs.x.ai/build/overview. The user guide ships with the pager crate: crates/codegen/xai-grok-pager/docs/user-guide/ — getting started, keyboard shortcuts, slash commands, configuration, theming, MCP servers, skills, plugins, hooks, headless mode, sandboxing, and more.

ImportantThe root Cargo.toml (workspace members, dependency versions, lints, profiles) is generated — treat it as read-only. Prefer editing per-crate Cargo.toml files.

Development cargo check -p <crate> # always target specific crates; full-workspace builds are slow cargo test -p xai-grok-config # per-crate tests cargo clippy -p <crate> # lint config: clippy.toml at the repo root cargo fmt --all # rustfmt.toml at the repo root Contributing
