Repository-Wide Code Simplification Initiative

[eapache-opslevel]

Code Complexity Reduction

This initiative successfully reduced code complexity across the repository by systematically applying best practices for code maintainability and readability.

Key Changes Implemented

Removed Dead Code: Eliminated unused imports (os, shutil, tempfile) from all Python files, reducing unnecessary dependencies and improving code clarity.

Reduced Function Length: Refactored four long functions (59-66 lines) by breaking them into smaller, focused units with single responsibilities. Functions like add_workflow(), process_repository(), and main() were split into multiple helper functions (3-4 each), making the codebase more maintainable.

Reduced Nesting Depth: Significantly reduced complexity in generate_summary_report() from a nesting depth of 6 to 2 by extracting nested logic into separate helper methods and using early returns. Applied guard clauses and early returns throughout validation functions.

Consolidated Duplicate Code: Created a shared test_utils.py module to eliminate duplicate run_command() implementations across test files, reducing code duplication and ensuring consistency.

Improved Code Organization: Extracted argument parsing into dedicated functions, standardized result dictionary creation, and added proper type hints for better code clarity and IDE support.

Impact

All functions now comply with best practices: no function exceeds 50 lines, nesting depth is kept at 3 or less, and there are no unused imports. The codebase is more maintainable, easier to test, and less prone to bugs. All existing integration and unit tests continue to pass, confirming that functionality remains intact while code quality has significantly improved.
