## Implementation Notes

### Development Environment Setup
- Ensure Google LLM provider is configured for testing
- Create test audio output directory
- Verify AudioGenerator utility is working correctly

### Code Quality Standards
- Follow existing TypeScript patterns in the codebase
- Use consistent error handling approaches
- Maintain compatibility with existing tool architecture
- Include comprehensive JSDoc comments

### Testing Strategy
- Unit tests should not require configured LLM providers (use mocks)
- Integration tests should gracefully handle missing LLM provider configuration
- Include both positive and negative test cases
- Test edge cases like very long text, invalid paths, etc.

### Security Considerations
- Validate all file paths to prevent directory traversal
- Sanitize text input to prevent injection attacks
- Ensure LLM provider configurations are handled securely
- Limit file output to project directories only

## Success Criteria

The implementation will be considered complete when:

1. **Functionality**: The AudioGenerationTool can successfully generate audio files from text using the Gemini API
2. **Integration**: The tool is properly integrated into the ToolManager and available in agent conversations
3. **Testing**: All unit and integration tests pass with good coverage
4. **Documentation**: The tool is properly documented with clear examples
5. **Security**: File operations are secure and contained within project boundaries
6. **Performance**: The tool performs efficiently without blocking other operations
7. **User Experience**: Error messages are clear and the tool is easy to use in agent conversations

## Future Enhancements (Out of Scope)
