- Duplicate code detection
- Function/file complexity analysis
- Naming convention check
- Type safety verification

### 2. Bug Detection
- Potential bug pattern detection
- Null/undefined handling check
- Error handling inspection
- Boundary condition verification

### 3. Security
- XSS/CSRF vulnerability check
- SQL Injection pattern detection
- Sensitive information exposure check
- Authentication/authorization logic review

### 4. Performance
- N+1 query pattern detection
- Unnecessary re-render check
- Memory leak pattern detection
- Optimization opportunity identification

## Review Output Format

```
## Code Review Report

### Summary

```

## Agent Integration

This Skill calls the `code-analyzer` Agent for in-depth code analysis.

| Agent | Role |
|-------|------|
| code-analyzer | Code quality, security, performance analysis |

## Usage Examples

```bash
# Review specific file
/code-review src/lib/auth.ts

# Review entire directory
/code-review src/features/user/

# PR review
/code-review pr 42

# Review current changes
/code-review staged
```

## Confidence-Based Filtering

code-analyzer Agent uses confidence-based filtering:

| Confidence | Display | Description |
|------------|---------|-------------|
| High (90%+) | Always shown | Definite issues |
| Medium (70-89%) | Selectively shown | Possible issues |
| Low (<70%) | Hidden | Uncertain suggestions |

## PDCA Integration

- **Phase**: Check (Quality verification)
- **Trigger**: Auto-suggested after implementation
- **Output**: docs/03-analysis/code-review-{date}.md
