# Code Review Router

Routes code reviews to the optimal CLI (Gemini or Codex) based on change characteristics.

## When NOT to Use This Skill

- For non-code reviews (documentation proofreading, prose editing)
- When reviewing external/third-party code you don't control
- For commit message generation (use a dedicated commit skill)
- When you need a specific reviewer (use that CLI directly)

## Step 0: Environment Check

Verify we're in a git repository:

```bash
git rev-parse --git-dir 2>/dev/null || echo "NOT_A_GIT_REPO"
```

**If not a git repo:** Stop and inform the user: "This directory is not a git repository. Initialize with `git init` or navigate to a repo."

## Step 1: Prerequisites Check

Verify both CLIs are available:

```bash
# Check for Gemini CLI
which gemini || echo "GEMINI_NOT_FOUND"

# Check for Codex CLI
which codex || echo "CODEX_NOT_FOUND"
```

**If neither CLI is found:** Stop and inform the user they need to install at least one:
- Gemini: Check Google's Gemini CLI installation docs
- Codex: Check OpenAI's Codex CLI installation docs

**If only one CLI is available:** Use that CLI (no routing needed).

**If both are available:** Proceed with routing analysis.
