1. Automated PR Review

1.1 PR Review Action

# .github/workflows/ai-review.yml

1.2 Review Comment Patterns

# AI Review Structure

## 📋 Summary

Brief description of what this PR does.

## ✅ What looks good

- Well-structured code
- Good test coverage
- Clear naming conventions

## ⚠️ Potential Issues

1. **Line 42**: Possible null pointer exception
   ```javascript
   // Current
   user.profile.name;
   // Suggested
   user?.profile?.name ?? "Unknown";
   ```

1. Line 78: Consider error handling

   // Add try-catch or .catch()
   

💡 Suggestions

• Consider extracting the validation logic into a separate function
• Add JSDoc comments for public methods

🔒 Security Notes

• No sensitive data exposure detected
• API key handling looks correct

### 1.3 Focused Reviews

```yaml
# Review only specific file types
- name: Filter code files
  run: |
    files=$(git diff --name-only origin/${{ github.base_ref }}...HEAD | \
            grep -E '\.(ts|tsx|js|jsx|py|go)$' || true)
    echo "code_files=$files" >> $GITHUB_OUTPUT

# Review with context
- name: AI Review with context
  run: |
    # Include relevant context files
    context=""
    for file in ${{ steps.changed.outputs.files }}; do
      if [[ -f "$file" ]]; then
        context+="=== $file ===\n$(cat $file)\n\n"
      fi
    done

    # Send to AI with full file context

        with:
          script: |
            const issue = context.payload.issue;

            // Call AI to analyze
            const analysis = await analyzeIssue(issue.title, issue.body);

            // Apply labels
            const labels = [];

            if (analysis.type === 'bug') {
              labels.push('bug');
              if (analysis.severity === 'high') labels.push('priorit
