# Technical Specification - Sanitizers

**Version**: v1.0.0 | **Status**: Planned | **Last Updated**: February 2026

**Module**: `codomyrmex.validation.sanitizers`  
**Last Updated**: 2026-01-29

## 1. Purpose

Input sanitization and normalization utilities

## 2. Architecture

### 2.1 Components

```

├── __init__.py          # Module exports
├── README.md            # Documentation
├── AGENTS.md            # Agent guidelines
├── SPEC.md              # This file
├── PAI.md               # Personal AI context
└── core.py              # Core implementation
```

### 2.2 Dependencies

- Python 3.10+
- Parent module: `validation`

## 3. Interfaces

### 3.1 Public API

```python
# Primary exports from codomyrmex.validation.sanitizers
# Not yet implemented. __all__ is empty; no public API is exported.
```

### 3.2 Configuration

Environment variables:
- `CODOMYRMEX_*`: Configuration options

## 4. Implementation Notes

### 4.1 Design Decisions

1. **Lazy-import stub**: Module is declared with an empty `__all__` and a commented-out `from .core import *` to support future lazy loading without startup cost.

### 4.2 Limitations

- No sanitization functions are implemented yet

## 5. Testing

```bash
# Run tests for this module
uv run pytest src/codomyrmex/tests/unit/validation/sanitizers/
```

## 6. Future Considerations

- Implement HTML/SQL/shell input sanitizers
- Add normalization utilities (whitespace, unicode, path canonicalization)
