Grok Build Shortcut

This is the Elves-managed Claude Code alias for /grok <instructions>.

Load the installed elves skill's Provider shortcut protocols and references/provider-shortcuts.md. Resolve scripts/run_grok.sh from the active Elves skill root, keep the target repository as the working directory, validate the instructions and CLI, and run it. Preserve the runner's headless non-bypass permission posture and its high reasoning default; do not invent a model id or turn this shortcut into an Elves main-driver route. The runner builds argv from the flags the installed Grok Build CLI advertises: an absent safety flag (isolated --cwd, inner --sandbox strict, headless --single, --output-format, explicit reasoning effort) fails closed, while a quality flag the installed version dropped is simply not passed. Auto-update is disabled through the isolated [cli] auto_update config key rather than a removed flag. Reasoning effort defaults to high; ELVES_GROK_EFFORT selects low, medium, high, or xhigh, and ELVES_GROK_MODEL pins a model only when the authenticated live catalog lists it. The runner reports the CLI version, effort, model, the authentication route the CLI itself names, and any omitted flags. On a host that cannot nest sandboxes (macOS Seatbelt refuses a second profile inside Elves' required outer sandbox-exec boundary), the runner fails closed with grok_inner_sandbox_unavailable before it builds a snapshot, rather than launching with the inner profile silently missing. Elves does not drop the inner profile to make a launch succeed, and the outer boundary is not optional; use a Linux host with the bwrap backend or select another review route. The Linux boundary omits procfs and has no /proc view; it does not receive Fugu's synthetic Codex /proc/self/exe link.

Read-only review snapshots omit oversized binary media instead of failing the whole review. Video, audio, presentation, archive, image, font, and 3D binaries above the per-file limit are left out and listed in the context manifest with path, byte size, and reason; the 16 MiB per-file limit is not raised. Source, prose instructions, executable agent configuration, and --include paths still fail closed and ask for a derived text, image, or transcript artifact.

Grok is an optional review route, like Fugu. On any non-zero exit the runner prints one directive line naming the reason (quota, authentication, catalog, runner, timeout, or provider). Select another available independent reviewer instead of stopping, record requested route, actual route, and fallback reason, and do not claim a review ran when it did not: python3 "$ELVES_SKILL_ROOT/scripts/cobbler_agents.py" review-route --host claude-code --requested grok --unavailable grok=<reason> --json.
