Hi @ashvin2005

Thank You for your contribution

The submitted files contain hundreds of lines of code with multiple functions, which makes them difficult to understand even with documentation.

Please organize and submit code snippets for specific use cases under dedicated folders (e.g., Catalog Client Script, Business Rule, etc.) along with a clear README file explaining the use case and the purpose of each script.

The current code is not ideal for code snippet submissions and make it harder to reuse the code effectively.
