# Dual AI Code Review

Get a second AI opinion on Claude Code's work using another AI model. Independent verification before merging.

## When to Use

- After Claude Code finishes implementing a feature or fix
- Before merging a PR
- When you want a structured code review from a different model

## How It Works

1. Gathers the git diff of recent changes
2. Sends the diff to a second AI model for structured review
3. If a PR exists, optionally requests automated PR review
4. Presents findings for Claude Code to address

## Process

### Step 1: Determine the Diff Range

Ask the user what to review:
- **Uncommitted changes**: `git diff` + `git diff --staged`
- **Last N commits**: `git diff HEAD~N..HEAD`
- **Branch diff**: `git diff main..HEAD`
- **Specific PR**: `gh pr diff <number>`

### Step 2: Run Second Model Review

Send the diff to your second model with a structured review prompt:

For GitHub Copilot CLI:
```bash
git diff <range> | gh copilot explain "Review this code diff for: bugs, security issues, performance problems, code quality, and missing tests. Format as Critical/Important/Minor issues."
```

For other tools, adapt accordingly.

### Step 3: Request Automated PR Review (Optional)

If there's an open PR and you're using GitHub Copilot:
```bash
PR_NUM=$(gh pr view --json number -q .number 2>/dev/null)
if [ -n "$PR_NUM" ]; then
  gh pr edit "$PR_NUM" --add-reviewer Copilot
fi
```

### Step 4: Present Findings

Show the user:
1. The second model's review output
2. Whether automated PR review was requested
3. Ask if Claude Code should address any findings

### Step 5: Fix Issues (Optional)

If the user wants to address findings, work through them:
- Critical issues first
- Then Important
- Then Minor

## Supported Second Models

| Tool | Best For | Notes |
|------|----------|-------|
| GitHub Copilot CLI | Quick code explanations | Requires Copilot subscription |
| OpenAI API | Detailed code review | Requires API key |
| Local model (Ollama) | Privacy-sensitive code | Free, runs locally |

## Setup

1. Install your preferred second model CLI tool
2. Configure authentication
3. Adapt the review command in Step 2 to match your tool
