Grok Plan Review (gr-plan-review)

Reviews Claude-generated implementation plans using your gr CLI and a full compacted view of the codebase via Repomix. Supports both manual invocation and automatic hook triggers on plan file saves.

Usage

Manual Invocation

/gr-plan-review
/gr-plan-review .claude/plans/my-plan.md

If no plan path is provided, defaults to the most recent plan in .claude/plans/.

What Happens

1. Runs repomix using the project's .repomix-review.config.json (or .repomix.config.json as fallback)
2. Combines the packed context + plan content into a structured prompt
3. Sends the prompt to gr (your Grok CLI) for expert review
4. Saves the full review as <plan-name>-review.md alongside the plan
5. Displays a confirmation and summary in the chat

Requirements

• repomix - Must be installed and in $PATH. Install via: npm install -g repomix
• gr - Your Grok CLI must be installed and authenticated. Run gr auth login once.
• jq - Required for parsing hook JSON input

Per-Project Configuration

Step 1: Create Repomix Config

Create .repomix-review.config.json in your project root (customize customPatterns for your codebase):

{
  "output": {
    "style": "xml",
    "filePath": ".gr-packed.xml",
    "removeComments": true,
    "removeEmptyLines": true
  },
  "include": ["**/*"],
  "ignore": {
    "defaultPatterns": true,
    "customPatterns": [
      ".git/**",
      ".claude/**",
      "node_modules/**",
      "build/**",
      "dist/**",
      "target/**",
      "bin/**",
      "*.log",
      "coverage/**",
      "docs/**",
      "README.md",
      "LICENSE",
      "**/*_test.go",
      "**/*.test.*",
      "go.sum",
      "**/vendor/**",
      "**/*.min.*"
    ]
  },
  "compress": true
}

Step 2: (Optional) Create Review Instructions

Create .claude/plan-review-instructions.md for project-specific review guidelines:

You are reviewing Claude-generated implementation plans for a [project type].
Emphasize: [your priorities like security, error handling, testing, etc.]

Step 3: Enable Automatic Hook (Optional)

Add to your project's .claude/settings.json:

{
  "plansDirectory": "./.claude/plans",
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "Write|Edit",
        "hooks": [
          {
            "type": "command",
            "command": ".claude/hooks/process-plan-review.sh",
            "async": true,
            "timeout": 240
          }
        ]
      }
    ]
  }
}

Hook Behavior

The hook script (process-plan-review.sh) automatically triggers when you write or edit files matching *plan*.md. It:

• Only acts on Markdown files containing "plan" in the path
• Runs Repomix to compact the project context
• Sends to Grok via gr CLI
• Saves review to <plan>-review.md
• Returns a summary to Claude Code via async hook JSON

The hook works independently of the skill and can be used standalone.

Installation via skm

skm install gr-plan-review

After installation, the skill is available at /gr-plan-review.

Troubleshooting

• "gr: command not found" - Ensure gr is in your $PATH and authenticated
• "repomix: command not found" - Install via npm install -g repomix
• Hook not firing - Verify the hook path in .claude/settings.json and reload with /hooks
• Review too slow - Reduce customPatterns in your Repomix config to exclude more files

Files Included

• hooks/process-plan-review.sh - Hook script for automatic plan review
• templates/repomix-review.config.json - Per-project Repomix configuration template
• templates/plan-review-instructions.md - Per-project review instructions template
