Grok Delegate

When to Use

• You want to delegate a bounded coding task to a separate grok implementer (Grok Build) and then review its diff yourself.
• The user explicitly asked for delegation to this implementer.

You are the orchestrator. This skill lets you hand a bounded coding task to a separate

implementer — the Grok Build CLI (grok) — then review what it produced and land it yourself. You

write the brief and own the judgment; Grok does the typing under an explicit autonomy profile; you

verify and commit.

Nothing here is specific to one orchestrating agent. The loop needs only the ability to run a shell

command and read a file, so it works the same whether you are Claude Code, Cursor, OpenCode with a

selected model, or any comparable agent. (It is designed for Claude Code and Cursor; treat other

orchestrators as designed-for, not yet proven.)

When NOT to use this

• The task is small enough to just do inline — delegation overhead is not worth it.
• The grok CLI is not installed, not authenticated, or the account lacks Grok Build beta access.
• You want to write the code yourself, or you only need a review without an implementer run.

Prerequisites (check once)

1. grok version succeeds. If not, install on any platform with

npm i -g @xai-official/grok (or use the installer from xAI's official Grok CLI docs) and

authenticate (grok login, or grok login --device-auth on headless hosts, or set

XAI_API_KEY).

2. Confirm which grok is on PATH. command -v grok shows the active binary and grok version

its version — the relay records the version it ran into result.json, so a stale binary is visible

after the fact.

3. You are in (or will point --cd at) the target git repository.

The loop

Run these five steps per task. Steps 1, 4, and 5 are your judgment; 2 and 3 are mechanical.

1. Write the brief

Grok sees only the text you send — no orchestrator chat history, no shared context. Everything the

task needs goes in the brief: the goal, the current state, what to change, what to leave untouched,

the project's actual gate commands (discover them from the repo's CLAUDE.md/AGENTS.md/Makefile —

do not assume), and a report contract. Tell Grok it will not commit (you will). Keep one task per

brief. Full guidance and a template: [references/writing-the-brief.md](references/writing-the-brief.md).

2. Dispatch

This distribution contains documentation only; scripts/relay.mjs is absent. Obtain,

pin and review the upstream runtime separately before using these example commands.

Do not search the whole home directory for an arbitrary relay and assume it is trusted.

Verify the actual CLI version and supported permission flags before dispatch.

node "<skill-dir>/scripts/relay.mjs" --brief brief.txt --cd /path/to/repo
# read-only (review/diagnosis; best-effort — verify touchedFiles): add --read-only
# continue the previous Grok session:       add --resume-last  (send only the delta brief)
# hard time limit (watchdog):               add --timeout 2h  (default: off; implementation runs routinely need 1-2h)
# see all options:                          node .../relay.mjs --help

The helper defaults to a write-capable (workspace-write) autonomy profile — --always-approve plus

--sandbox workspace — and writes its artifacts to a temp dir, so the repo under review stays clean.

It never commits — see step 5. Mechanics, flags, and the result.json shape:

[references/dispatch-and-poll.md](references/dispatch-and-poll.md).

3. Wait for completion

The helper blocks until Grok finishes, so back it with whatever your orchestrator offers and resume

when it returns:

• Claude Code: run the Bash call with run_in_background: true; you are notified on completion.
• Plain shell / other agents: run it in the foreground for short tasks, or background it and poll

the result file — … & in bash/zsh (including Git Bash/WSL), or your shell's equivalent (Start-Job

in PowerShell, start /b in cmd). The run is done when result.json exists with a status. (A

pre-run usage error — bad args or an empty brief — instead exits with code 2 and a stderr message and

writes no result file, so check the exit code too. A missing grok binary exits 127 but *does* write

a result.json with status grok_unavailable.)

Do not trust progress trackers over reality: a run is finished when result.json is written and the

process has exited. Read the working tree, not a status line. The implementer's full report is

the finalMessage field in result.json (also printed in full on stdout between the report markers).

4. Review — do not trust the self-report

Grok's result.json includes its own summary and gate claims. Re-verify, don't accept:

• Re-run the project's gates yourself (the test/lint/build commands from step 1). Never take

"gates passed" on faith.

• Read the diff against the brief: did Grok do what was asked, nothing more (scope creep) and

nothing less? touchedFiles in the result is your starting point.

• Run the relevant guard skills on the diff if you have them installed (clean-code-guard,

test-guard, etc. from guard-skills) — this skill produces the work; those skills judge it.

• For schema/migration changes, round-trip them; for removals, grep for dangling references.

Full checklist: [references/review-and-land.md](references/review-and-land.md).

5. Land it

The orchestrator commits. Only after the gates pass and the diff holds:

• Commit the verified work yourself, with a clear message.
• If it needs changes, send a delta brief with --resume-last (don't restate the whole task) and

review again.

Autonomy model

Grok's default permission mode is ask, which blocks on approval prompts in a headless pipe. The

relay therefore always sets autonomy explicitly:

| Relay flag | What Grok gets | Use when |

| --- | --- | --- |

| *(default)* | --always-approve --sandbox workspace | Normal implementation — writes scoped to the working tree |

| --read-only | --sandbox read-only --permission-mode plan | Review / diagnosis — best-effort, not enforced (see caveat below) |

| --full-access | --always-approve --sandbox off | Explicit opt-in when the task needs unrestricted tools |

--always-approve alone would approve *all* tools (writes, shell, network) — closer to unrestricted

than to a workspace-scoped write. The effective filesystem/network boundary must be verified for the installed version; a workspace sandbox is not a universal host boundary. Reach for --full-access only when the human asks for it.

--read-only is best-effort, not a hard guarantee. The read-only sandbox restricts out-of-workspace

filesystem/network access, not grok's own edit tool, and headless plan mode is advisory — a run

verified here still wrote the working tree when told to. Use --read-only to *signal* review intent,

but always confirm touchedFiles afterward; treat the diff, not the flag, as the guarantee. The relay

automates a reporting tripwire: it compares parsed git porcelain and fingerprints the working-tree

identity and index entries of Git-visible paths that were already dirty. readOnlyViolation is true

when either signal proves a change, false when coverage is complete and detects none, and null when

coverage is incomplete. Ignored paths, submodule internals, perfect restores, and attribution of

concurrent changes remain outside it, so the diff

review stays the guarantee.

Authorization model

Delegation is something the human opts into. Once they have ("run this queue", "proceed"), committing

verified, gate-passing work is the agreed contract — that is the whole point. Two limits on that

mandate: surface, don't absorb (report Grok's design decisions, defensible-but-unasked turns, and

non-blocking nitpicks rather than silently keeping them) and stop for scope changes (if correct

completion needs going beyond the brief, ask — don't expand the mandate yourself). The full treatment

is in [references/review-and-land.md](references/review-and-land.md).
