Why 4: after you approve or rewrite its plan, it edits files, runs shell commands and delegates to subagents, and can run headless in scripts; it does not act unprompted.
What it does. Grok Build is a command-line agent that drafts a plan you can approve or rewrite, then edits files and runs shell commands, delegating parts of larger jobs to subagents that run at the same time. It can also run headless inside scripts and works with existing AGENTS.md files, hooks and MCP servers. After a privacy row in July 2026 its source code was published on GitHub under the Apache 2.0 licence.
Where it falls short. It launched as an early beta and its data handling was found wanting within two months. The model and harness are less proven than the established coding agents.

Incidents
- 2026-07-13 Researchers reported that Grok Build had uploaded entire Git repositories, which could include credentials and history, to xAI-linked cloud storage, far more than its tasks needed; the uploads were later switched off by a server-side flag. Source
