- **Security Features**: Path traversal protection, input sanitization
## Usage Examples
### Basic Validation
```python
from pacc.validators import ValidatorFactory
# Validate a hooks file
validator = ValidatorFactory.create_validator('hooks')
result = validator.validate('/path/to/hooks.json')
if result.is_valid:
print("Validation passed!")
else:
for error in result.errors:
print(f"Error: {error.message}")
```
### Interactive Selection
```python
from pacc.selection import SelectionWorkflow
# Create interactive selection workflow
workflow = SelectionWorkflow()
selected_files = workflow.run_interactive_selection('/path/to/extensions/')
```
### Directory Scanning
```python
from pacc.core.file_utils import DirectoryScanner, FileFilter
# Scan directory for extension files
scanner = DirectoryScanner()
file_filter = FileFilter().by_extensions(['.json', '.md', '.yaml'])
files = scanner.scan('/path/to/directory', file_filter)
```
