# Pydantic Settings

## Overview
Pydantic Settings provides configuration management using Pydantic models, automatically parsing environment vars.

## When to Use This Skill
Use to load and enforce system configuration parameters strictly inside backend servers.

## Quick Start (with runnable code examples)

```python
from pydantic_settings import BaseSettings

class ServerSettings(BaseSettings):
    bot_token: str
    db_port: int = 5432
    
    class Config:
        env_file = ".env"

# Auto-loads from system variables or .env
settings = ServerSettings()
print("Port:", settings.db_port)
```

## Advanced Usage
Implement nested configuration schemas, validate settings values, and handle variable overrides during unit testing runs.
