Grok Build just got a major update with a ton of new features and improvements
Release Notes: v0.2.51
Breaking Changes:
• grok mcp add now accepts positional arguments (e.g. grok mcp add filesystem -- npx ...), supports --scope project, and adds -e/-H flags for env/headers.
Features:
• Mermaid flowcharts now render subgraph blocks as titled frames with correct internal and cross-boundary edges.
• Class diagrams in Mermaid now render as proper UML boxes with attributes, methods and inheritance arrows instead of raw source.
• Permission prompts now accept a double-click on an option to submit it, matching the existing Enter and number-key shortcuts.
• New /code-review slash command now ships with the CLI and is always available
Bug Fixes:
• Plan mode exit reminders no longer appear after the model has already started implementing the plan.
• Expanded thinking blocks in scrollback now remain expanded when the agent finishes them.
• grok update no longer downloads the same binary twice when multiple updaters or leader checks run concurrently.
• Background task IDs after /compact are now shown verbatim so the model can reference them correctly in later tool calls.
• Typing / while scrollback is focused now focuses the prompt and opens the slash-command dropdown.
