离谱的是——昨天 xAI 开源了 Grok Build，大家都在刷屏。但五天前，同一个 xai-org 账号悄悄发布了另一件东西：一个官方的 Claude Code 插件。

零公告。零推文。连作者都没提过。

7 个星标。1 个 fork。

这个插件做了这几个命令，让 Claude Code 可以直接调用 Grok Build CLI：

1. 审查代码（/grok-build:review）

2.批评设计决策（/grok-build:critique）

3.委派调查任务（/grok-build:delegate）

4.导入 Claude 会话到 Grok（/grok-build:import）

它本质上是在竞争对手的终端上，为自己建了一座桥。

这不是“多模型策略”的宣传稿，是 xAI 的工程师直接写出来的代码。

建议直接收藏，在 xAI 注意到之前装好试试。

Grok Build ↔ Claude Code Bridge

Bridge Grok Build into Claude Code for review, critique, delegation, and session import.

This repository is a Claude Code marketplace plugin that shells out to the real grok CLI. Run status, results, and stop are owned by the plugin (PID + log files). There is no app-server broker.

Requirements

• Node.js >= 18.18
• Grok Build CLI (grok) on PATH, or set GROK_BINARY
• A logged-in Grok CLI session (grok models succeeds)

Local install

From this repository root (path must be absolute):

# Resolve an absolute path to this clone, then add it as a local marketplace
claude plugin marketplace add "$(pwd)"
# example: claude plugin marketplace add /absolute/path/to/grok-build-plugin-cc

# Install the plugin from that marketplace
claude plugin install grok-build@xai-grok-build

Or, when Claude Code is already open, use /plugin and add the local marketplace path, then install grok-build@xai-grok-build.

Check readiness

/grok-build:check

Ready means: Node is available, grok is available, and soft auth via grok models succeeds.

Commands

/grok-build:check

Probe Node + Grok CLI availability and authentication.

/grok-build:review

Read-only review of local git state:

/grok-build:review --wait
/grok-build:review --background --scope working-tree
/grok-build:review --base main
/grok-build:review --wait --model grok-build --effort high

Runs:

grok -p <prompt> --agent explore --permission-mode plan --sandbox read-only --cwd <ws> --output-format plain

Optional: pass --model / --effort (low|medium|high). If omitted, Grok chooses defaults.

/grok-build:critique

Same target selection as review, with a design/risk critique prompt and structured JSON output when possible:

/grok-build:critique --wait
/grok-build:critique --base main challenge whether this was the right caching and retry design
/grok-build:critique --wait --model grok-build --effort high focus on failure modes

Optional: same --model / --effort flags as review.

/grok-build:delegate

Delegate investigation or implementation to Grok via the grok-build:grok-delegate subagent:

/grok-build:delegate investigate the flaky test in auth
/grok-build:delegate --resume apply the top fix
/grok-build:delegate --model grok-build --effort high fix the race

Write policy layering:

• Direct node …/grok-bridge.mjs run "…" is therefore read-only unless --write is passed.
• --resume / --resume-last continues the last stored Grok session id via grok -r <id>.
• Prefer bridge --background for long work so runs record both bridgePid (Node worker) and agentPid (grok child).
• /grok-build:stop terminates both process trees when present (agent then bridge/worker).
• If you do not pass --model or --effort, Grok chooses its own defaults.

/grok-build:import

Import the current Claude transcript into Grok:

/grok-build:import
/grok-build:import --source ~/.claude/projects/.../session.jsonl

Uses grok import and prints a resume hint: grok -r <id>.

/grok-build:runs

List active and recent plugin-owned runs:

/grok-build:runs
/grok-build:runs <run-id> --wait

/grok-build:show

Show stored output for a finished run:

/grok-build:show
/grok-build:show <run-id>

/grok-build:stop

Stop an active run by terminating tracked process trees:

/grok-build:stop
/grok-build:stop <run-id>

Kills every distinct pid among agentPid (detached grok child) and bridgePid / legacy companionPid / legacy pid (bridge or run-worker). Terminal status is claimed under a locked CAS so a finishing worker cannot overwrite cancelled with completed.

Environment

State fallback when CLAUDE_PLUGIN_DATA is unset: $TMPDIR/grok-cc-runs.

Development

npm test

Tests use Node’s built-in test runner and a fake grok binary on PATH. Runtime code uses Node stdlib only.
