│   ├── __init__.py
│   ├── aws.py
│   ├── files.py
│   └── config.py
├── utils/         # Utilities
│   ├── __init__.py
│   ├── logging.py
│   └── helpers.py
└── exceptions.py  # Custom exceptions
```

## 🧪 **Testing Improvements**

### Current State ✅

#### 2. Enhanced Test Structure (Optional)

```
tests/
├── unit/
│   ├── test_aws.py
│   ├── test_files.py
│   └── test_config.py
├── integration/
│   └── test_cli_integration.py
├── fixtures/
│   └── conftest.py
└── test_utils.py
```

#### 3. Test Coverage Reporting

The current setup supports coverage reporting via the Makefile:

```bash
make test-coverage  # Runs tests with coverage reporting
```

## 🔧 **Code Quality Improvements**

### Current State ✅

- ✅ **Code formatting**: Ruff configured for formatting and linting
- ✅ **Pre-commit hooks**: Automated code quality checks on commit
- ✅ **Type hints**: Partial implementation with ty configuration
- ✅ **Error handling**: Basic error handling with try/catch blocks

    # Implementation
```

#### 2. Enhanced Error Handling

Consider adding custom exception classes:

```python
class MediaMgmtError(Exception):
    """Base exception for media management operations."""
    pass

class ConfigError(MediaMgmtError):
    """Configuration-related errors."""
    pass

class AWSConnectionError(MediaMgmtError):
    """AWS connection errors."""
    pass
```

#### 3. Comprehensive Docstrings

Enhance existing docstrings with more detail:

```python
def upload_file(self, file_name: str) -> bool:
    """
    Upload a file to S3.

    Args:
        file_name: Path to the file to upload

    Returns:
        True if upload successful, False otherwise

    Raises:
        AWSConnectionError: If connection to AWS fails
        FileNotFoundError: If file doesn't exist
    """
```

    - Uses `uv` for dependency management
    - Automated testing on pull requests

- **Pre-publish workflow** (`.github/workflows/pre-publish.yml`):
    - Builds and publishes to TestPyPI
    - Runs on main branch pushes

- **Publish workflow** (`.github/workflows/publish.yml`):
    - Publishes to PyPI
    - Automated release process

- ✅ **Input validation**: Basic validation in CLI commands
- ✅ **AWS integration**: Secure AWS credential handling through boto3

### Current Configuration Setup

#### 1. Configuration Management

Current `Config` class in `mgmt/config.py`:

- Environment variable based configuration
- Secure storage in `~/.config/mgmt/config`
- Support for AWS bucket, object prefix, and local directory settings

#### 2. Security Features

- AWS credentials handled through standard boto3 credential chain
- Configuration files stored in user's home directory
- No hardcoded secrets in code

### Areas for Enhancement

#### 1. Enhanced Configuration Validation

Consider using Pydantic for more robust validation:

```python
from pydantic import BaseSettings, Field

class Settings(BaseSettings):
    bucket: str = Field(..., description="S3 bucket name")
    prefix: str = Field(default="", description="S3 object prefix")
    local_dir: str = Field(..., description="Local media directory")

    class Config:
        env_file = ".env"
        env_prefix = "MGMT_"
```

#### 2. Input Validation

Add more comprehensive input validation:

```python
from pydantic import validator

@validator('bucket')
def validate_bucket(cls, v):
    if not v or not v.strip():
        raise ValueError('Bucket name cannot be empty')
    return v.strip()
```

## 📊 **Monitoring & Logging**

### Current State ✅

- ✅ **Logging implementation**: Custom `Log` class with structured logging
- ✅ **Debug capabilities**: Configurable debug levels
- ✅ **File and method tracking**: Automatic file and method name logging
- ✅ **Multiple log levels**: Debug, info, warning, error levels supported

### Current Logging Setup

#### 1. Custom Logging Class

Current `Log` class in `mgmt/log.py`:

- Configurable debug levels
- Automatic file and method name tracking
- Multiple log levels (debug, info, warning, error)
- Stream handler with formatted output

#### 2. Usage Throughout Codebase

- Used in `FileManager` for operation logging
- Used in `Config` for configuration logging
- Integrated with AWS operations

### Areas for Enhancement

#### 1. Structured Logging

Consider upgrading to structured logging:

```python
import structlog

logger = structlog.get_logger()

def upload_file(self, file_name: str) -> bool:
    logger.info("Starting file upload", file_name=file_name)
    try:
        # upload logic
        logger.info("File upload successful", file_name=file_name)
        return True
    except Exception as e:
        logger.error("File upload failed", file_name=file_name, error=str(e))
        return False
```
