Grok Build /goal Mode Now Live: xAI Coding Agent Plans, Executes, and Self-Verifies Long Tasks Autonomously

• xAI announced /goal mode for Grok Build on June 22 and coverage expanded June 24: the new command puts Grok Build into a long-running autonomous execution loop that plans the full task, executes steps in sequence, and self-verifies results without requiring per-step user input.
• TechTimes confirmed the feature is live and positions Grok Build as a direct competitor to Claude Code's auto mode and Codex Remote for agentic workflows.

Editor’s read: /goal mode is the missing piece for Grok Build as a production agent. If you have been watching from the sidelines, run /goal on a contained, reversible task this week and compare it to your current Claude Code or Codex workflow.
