I demonstrate how it analyzes a Python file, identifies issues, and automatically applies fixes with just one click, transforming hours of manual work into a 30-second task. The tool scanned six files and found seven missing type hints, ultimately achieving a 100% healthy codebase. I encourage you to explore the GitHub repository for Tech-Debt Assertion and see how it can enhance your development process.
