Auto PR Review

## Overview

GitHub Copilot Code Review analyzes every pull request diff and posts inline comments focusing on bugs, security issues, and logic errors. It runs as a built-in GitHub feature — no custom GitHub Action required.

## How to Enable

1. Go to your repository or organization **Settings → Copilot → Code Review**
2. Enable **Copilot Code Review** for pull requests
3. Optionally configure a `copilot-review-config.yml` in `.github/` to customize review behavior

## How It Works

1. A PR is opened or updated
2. Copilot automatically analyzes the diff
3. Inline comments are posted as a review on relevant lines
4. A summary comment provides an overall assessment

## Requesting Review Manually

You can also request Copilot as a reviewer on any PR:

1. Open the PR → **Reviewers** → add **Copilot**
2. Or use GitHub CLI:

```bash
gh pr edit <number> --add-reviewer copilot
```

## Optional: Trigger Review via Workflow

To ensure Copilot review is always requested on new PRs automatically:

```yaml
name: Request Copilot Review
on:
  pull_request:
    types: [opened, synchronize]

jobs:
  request-review:
    runs-on: ubuntu-latest
    steps:
      - name: Add Copilot as reviewer
        env:
          GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        run: gh pr edit ${{ github.event.pull_request.number }} --add-reviewer copilot --repo ${{ github.repository }}
```

## Tips

- Copilot Code Review works best with clear PR descriptions and focused diffs
- It catches common bugs, security anti-patterns, and logic errors
- For high-risk changes, combine with human review — Copilot supplements but does not replace reviewers
