Grok Build 1.0.31

1.0.30→1.0.31·September 13, 2026 at 3:37 PM UTC

Patch release 1.0.31: Cursor private-worker “any-repo” cloning, clearer subagent list controls, and richer reference-to-video framing, plus refreshed marketplace plugins.

Changelog

  • [new] Cursor private worker — any-repo door. When the leader registers as a Cursor private worker, a successful start can open a clone-pool door for git URLs outside worker_dirs. New config cursor_worker.any_repo (default true) registers that door so Cloud Agents can bring arbitrary repositories. cursor_worker.max_agents is now the concurrent claim cap per door.
  • [new] Subagent list filtering. In the tasks pane (Ctrl+G), press h to toggle hide-completed / show-all. With the dock enabled and focused, h does the same; Left / Right collapse and expand a section header.
  • [changed] reference_to_video. You can pin exact first/last frames and up to four mid-clip keyframes (snapped to a 1/3-second grid), use up to 14 style/content reference images (was 7), and mix references with voices. Prompt image tags follow upload order when pinned frames are set.
  • [changed] Marketplace plugins refreshed (source revisions): figma, modern-web-guidance, netlify, pstack, stripe, vercel, and wix. Stripe’s stripe-best-practices and Vercel’s flags-sdk skill blurbs were updated.
  • [changed] Docs for subagents and the cursor_worker config reference match the above behavior.

Under the hood

  • Cursor worker support is split into door registration, clone/fetch, and git-credential handling so private workers can serve both fixed worker_dirs and on-demand clones.
  • New agent-host state and transport groundwork; pager/agent runtime wiring refined.
  • Worktree strategy plumbing updated.
  • Env/feature knobs: GROK_HOI added; scroll-cadence control is GROK_SCROLL_CADENCE_MSO (replacing GROK_SCROLL_CADENCE_MS).
  • Git-config auth helpers for clone-ready Cursor workers (auth.gitconfig.*).

Upgrade notes

  • If you rely on cursor_worker.max_agents, treat it as a per-door limit (worker-dirs door and any-repo door each have their own pool).
  • To disable cloning of repos not listed in worker_dirs, set cursor_worker.any_repo to false.
  • If you set scroll cadence via env, switch from GROK_SCROLL_CADENCE_MS to GROK_SCROLL_CADENCE_MSO.
