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.
