✅ **Production-Ready**: Used in django-wallet-utils  

## 💡 Example Use Case

```python
from django_hooks import HookContext, HookType, register_hook, HookRejectionError

# 1. Define context
@dataclass(frozen=True)
class CronjobHookContext(HookContext):
    job_id: str
    schedule: str
    user_id: int

# 2. Create hook
def check_permission(context):
    if not user_can_schedule(context.user_id):
        raise HookRejectionError('PERMISSION_DENIED', 'Access denied')
    return True

# 3. Register hook
register_hook('permission', HookType.PRE, check_permission, priority=10)

# 4. Use in service
manager = HookManager()
try:
    manager.execute_pre_hooks(context)
    result = schedule_job(...)
except HookRejectionError as e:
    return {'error': e.error_code, 'message': e.message}
```
