Consider making validation system a separate package

[itsmattius]

The validation system in TagGen AI could be extracted into a separate reusable package for better modularity and reusability across different projects.

Current State

• Validation system is tightly coupled with TagGen AI
• Limited reusability across different projects
• Validation logic mixed with business logic

Benefits of Separation

• Reusable across multiple AI projects
• Better maintainability and testing
• Independent versioning and updates
• Cleaner separation of concerns
• Easier to contribute and collaborate

Proposed Structure

• Create a new package: taggen-validation
• Extract validation classes and utilities
• Maintain backward compatibility
• Add comprehensive documentation
• Include example usage

Technical Details

• File: src/validation/__init__.py:1
• Current validation system includes:
  • Request validation
  • File validation
  • Examples validation
• Need to identify reusable components

Acceptance Criteria

• Analyze current validation system
• Identify reusable components
• Design package structure
• Create new package repository
• Migrate validation logic
• Update TagGen AI to use new package
• Add comprehensive documentation
• Create migration guide
