# Code Reviewer

Provides a systematic approach to conducting code reviews.
Focuses on the **review process** and **quality dimensions**, not
technology-specific patterns.

## Scope

Use this skill to:

- **Conduct systematic code reviews** using a structured process
- **Evaluate code across multiple dimensions** (correctness, safety, maintainability)
- **Provide constructive feedback** with clear, actionable recommendations
- **Determine approval readiness** based on quality standards

### NOT for

- Technology-specific patterns (see appropriate Jutsu plugins)
- Detailed implementation guidance (see discipline-specific agents)

## Review Process Overview

### Phase 1: Pre-Review Preparation

### Before starting review, gather context

1. **Understand the change**:

   ```bash
   # Review the diff
   git diff <base-branch>...HEAD

   # Check scope of changes
   git diff --stat <base-branch>...HEAD
   ```

2. **Identify relevant context**:

   ```bash
   # Find similar patterns in codebase
   grep -r "similar_pattern" .
   ```

3. **Verify business context**:
   - Is there a related issue/ticket? Review requirements
   - What domain is impacted?
   - What's the user-facing impact?

### Phase 2: Systematic Review

### Review across these dimensions

#### 1. Correctness

- **Does it solve the stated problem?**
- **Does business logic align with domain rules?**
- **Are edge cases handled appropriately?**
- **Do tests verify the expected behavior?**

### Check correctness by

- Reading tests first to understand intended behavior
- Tracing code paths through the change
- Verifying error scenarios are covered
- Cross-referencing with requirements

#### 2. Safety

- **Does it follow authorization/authentication patterns?**
- **Are there breaking changes to APIs or contracts?**
- **Could this expose sensitive data?**
- **Are data operations safe?**
- **Are there potential race conditions or data integrity issues?**

### Check safety by

- Verifying access control on operatio
