At a glance

Run a bounded-permission headless Grok Build task. An agent skill from aigorahub/elves.

  • The user types /grok
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Asks Grok Build to execute instructions

What it does

Grok is an agent skill from aigorahub/elves. Run a bounded-permission headless Grok Build task. Use when the user types /grok or asks Grok Build to execute instructions.

Its SKILL.md is about 770 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows. The repository describes itself as: Autonomous multi-batch development skill for Claude Code and Codex. They work while you sleep. The licence is MIT.

When your agent uses it

  • The user types /grok
  • Asks Grok Build to execute instructions

Example prompts

  • “/grok”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit fba17a3. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Grok loads about 766 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 401 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~766

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
