Patch release 1.0.1: grok du for home-directory disk usage, clearer skill/built-in slash collisions, a redesigned /rewind, and marketplace updates including the new mongodb-atlas plugin.
Changelog
[new]grok du (alias grok disk-usage) reports what ~/.grok uses on disk: top-level directories largest-first, then each worktree with size, type, age, label, and path. Untracked worktrees are called out; --json emits the same report for scripts. Completions cover bash, zsh, fish, elvish, and PowerShell.
[new] Bundled skill-design-principles skill — concise guidance for writing and editing skills (single source of truth, no no-op sprawl, generalize carefully). The create-skill flow points authors at it when drafting a new skill body.
[new] Marketplace plugin mongodb-atlas (managed Atlas MCP server + skills for stream processing, connections, natural-language querying, query optimization, schema design, and search/AI). The existing mongodb plugin is scoped to self-managed deployments via your connection string.
[new]/rename --auto unpins a manual title and restores auto-titling on Build sessions (must be the only argument).
[changed]/rewind (alias /undo) rewinds conversation history to an earlier turn only; it no longer restores files on disk. Optional confirm-before-rewind (default on in /settings) offers Yes / Yes, and don't ask again / No.
[changed] When a skill reuses a built-in slash name (e.g. login), the built-in keeps the bare command and the skill stays available as a qualified name (/plugin:login, /local:compact, …). The menu badges both rows; grok inspect and skills --json surface collision metadata (collidesWith / invocableAs).
[changed]/delete stops any running turn, background tasks, and subagents before wiping session history.
[changed] Sandbox read_only / read_write path grants are literal directories (not globs); a trailing /** or /* is treated as the parent directory. Glob-like or whitespace-padded entries are skipped with a warning — put globs under deny.
[changed] Model-launched workflows: host concurrent child-agent cap defaults to 32 (was a fixed 16); still host-configurable. agent_budget behavior is unchanged.
[changed] Cancel-turn panel: “keep running” closes the panel and leaves the turn (and subagents) running; Enter / 1–4 still choose cancel-and-subagent options.
[changed]Notification hooks are documented as user-attention events (idle_prompt, permission_prompt, task_complete, …). Claude-style finish chimes should match idle_prompt; permission_prompt fires only when a permission UI is waiting.
[changed] Marketplace updates: stripe gains stripe-apps; vercel gains vercel-services; sentry adds sentry-fix-stack-traces and sentry-setup-releases, and drops sentry-feature-setup, sentry-sdk-upgrade, sentry-setup-ai-monitoring, and sentry-workflow. chrome-devtools, figma, mongodb, railway, stripe, sentry, and vercel pick up newer plugin revisions.
[changed]reference_to_video accepts optional preset voices (with <AUDIO_n> tags), makes images optional when voices are provided, widens duration (1–15s) and aspect-ratio choices, and tags image refs as <IMAGE_n> in the prompt.
[changed] Permission rule tool-name list no longer lists NotebookRead / NotebookEdit as aliases (use Read / Edit / Write as before for file tools).
[changed]grok mcp enable / disable no longer treat legacy managed grok_com_* names as known without a local entry; plugin and compat sources are unchanged.
[changed] Docs and monitoring: startup latency metrics (grok_code.startup.total, phase_duration, timeout) with auth_mode and phase breakdowns; session storage notes that history files dominate disk use (not rewind file copies).
Under the hood
GROK_EXIT_TIMEOUT_SECS — seconds after quit before a force-exit if teardown hangs (default 20; 0 disables; hard exit follows 5s later).
Additional concurrency-related knobs for workflows/subagents (GROK_WORKFLOW_MAX_CONCURRENT_AGENTS, GROK_MAX_CONCURRENT_SUBAGENTS, GROK_SUBAGENT_LIMIT_BEHAVIOR) and related workspace/env support.
Startup telemetry instrumentation and session storage/search/replay groundwork; sandbox path-allow handling tightened to match the literal-grant docs.
Bundled content refresh (public-2026-08-10-r1); model catalog surfaces grok-4.5.
Upgrade notes
/rewind no longer reverts files. Only conversation history is truncated; on-disk edits from dropped turns stay. Rely on git (or other VCS) if you need file-level undo. Confirm-before-rewind defaults on; turn it off from the rewind prompt or /settings.
After large worktree growth, run grok du, then reclaim with grok worktree gc --max-age <duration> --dry-run (and without --dry-run). GC only touches registry-tracked worktrees; remove untracked paths with grok worktree rm.
If you depended on Sentry skills sentry-feature-setup, sentry-sdk-upgrade, sentry-setup-ai-monitoring, or sentry-workflow, switch to the replacement Sentry skills in this release.
Prefer mongodb-atlas for signed-in Atlas resource management; keep mongodb for self-managed connection-string workflows.
