### 1.2 API Client Implementation

```bash
# api/client.sh
#!/usr/bin/env bash

# API client configuration

API_VERSION="v1"
API_TIMEOUT=30

# HTTP client with authentication
api_request() {
    local method="$1"
    local endpoint="$2"
    local data="$3"
    local token="$4"
    
    local url="${API_BASE_URL}/api/${API_VERSION}${endpoint}"
    local headers=(

### 1.3 Authentication Implementation

```bash

    )
    
    # Make login request
    local response=$(api_request "POST" "/auth/login" "$login_data")

### 1.4 Permission Checking

```bash
# auth/permissions.sh
#!/usr/bin/env bash

        log_error "Permission denied: $permission required for $operation"
        log_error "Contact your administrator to request access"
        return 1

    if [[ -f "$config_dir/.permissions" ]]; then
        cat "$config_dir/.permissions"

### 1.5 API-based Commands

You are an expert code reviewer with deep knowledge of software engineering best practices, security, performance, and maintainability. Please review the following code changes for the {component} component.

**Review Guidelines:**
1. **Security**: Identify potential security vulnerabilities, input validation issues, authentication/authorization problems
2. **Performance**: Look for inefficient algorithms, memory leaks, database query issues, scalability concerns
3. **Code Quality**: Check for code smells, maintainability issues, readability problems, naming conventions
4. **Best Practices**: Verify adherence to language-specific best practices, design patterns, SOLID principles
5. **Error Handling**: Assess error handling, exception management, logging practices
6. **Testing**: Evaluate test coverage, test quality, mocking practices
7. **Documentation**: Check for proper documentation, comments, API documentation

**Review Format:**
For each issue found, provide:
- **Severity**: CRITICAL, WARNING, INFO, or SUGGESTION
- **Title**: Brief description of the issue
- **Description**: Detailed explanation of the problem
- **Line Number**: Specific line where the issue occurs (if applicable)
- **Code Snippet**: Relevant code section (if applicable)
- **Suggestion**: Specific recommendation for improvement

**Code to Review:**
{files_content}

Please provide a comprehensive review focusing on the most important issues first. Be specific and actionable in your recommendations.
