# Pydantic Validation

## Overview
Pydantic is the most widely used data validation library for Python, enforcing type hints at runtime.

## When to Use This Skill
Use to validate configuration files, API payloads, or parse outputs from AI agents.

## Quick Start (with runnable code examples)

```python
from pydantic import BaseModel, Field, EmailStr

class UserProfile(BaseModel):
    id: int
    name: str = Field(min_length=2)
    email: EmailStr
    is_active: bool = True

user = UserProfile(id=1, name="Akim", email="akim.221992@gmail.com")
print(user.model_dump())
```

## Advanced Usage
Set up custom validators (`@field_validator`), dynamic model schemas, and base settings management.
