For complex tasks, users start with "Plan Mode." This allows users to approve the plan before execution, comment on individual steps, or rewrite the plan entirely. Once changes are executed based on the approved plan, all modifications are displayed as clean diffs.
Additionally, AGENTS.md files, plugins, hooks, skills, and MCP servers within a repository continue to function as usual. When Grok Build is started within a repository, it immediately recognizes existing conventions.
For large-scale tasks, the agent delegates work to specialized sub-agents that run in parallel. It also supports deep worktree integration, enabling sub-agents to be launched in dedicated worktrees.
Furthermore, a headless mode (-p) is provided for running the agent within scripts or automation. It also features full ACP support for building custom bots or agent orchestration applications.
As this is an early beta, xAI stated that feedback to the team is the fastest way to achieve improvement. Users can send bugs, requests, and reactions directly to the team by typing /feedback within Grok Build.
