Grok Build is xAI's open-source terminal coding agent in Rust. Install guide, real commands, ACP editor integration, costs, community reaction, and honest limits.

What Grok Build Actually Does

Grok Build is not a chat window with a code theme. It's an agent harness: a loop that plans, calls tools, reads results, and iterates until a task is done. The pieces that matter:

- Codebase-aware editing. It reads files, greps, lists directories, and applies patches — the standard read/search/edit toolchain, ported and refined (more on that below).

- Shell execution. It runs commands in your workspace with a checkpoint layer so you can review and roll back what the agent did.

Installing Grok Build

The released binary is the fast path. Prebuilt binaries exist for macOS, Linux, and Windows:

On first launch it opens your browser to authenticate against your xAI account — no manual API-key juggling for the default path.

> A note on curl | bash: piping an install script straight into a shell is convenient but runs remote code with your user's permissions. If that makes you uneasy (it should, at least a little), download the script first, read it, then run it. This is standard hygiene for any one-line installer, not a Grok-specific worry.

A Realistic First Session

Once installed and authenticated, the loop looks like every good agentic CLI:

That drops you into the fullscreen TUI. From there you describe a task in plain language:

> Add a --json flag to the export command that prints results as
