jelasion101/cookiechecker — reverse-engineered prompt

Build me a simple Python cookie checker for Roblox that I can run from a folder on my computer. I want to paste my own cookies into a file called cookies.txt, one per line, run the script, and have it check which ones still work.

When it finishes, it should create two separate output files called Validcookies and Invalidcookies, and put each cookie in the right one. Please make it easy to run from the terminal, show a simple progress message while it works, and handle blank lines or bad entries without crashing.

Use Python with requests, and keep it beginner friendly because I’m not very technical. Add a clear note in the script that it is only for checking cookies I own or have permission to test, not for stealing accounts or anything malicious. Don’t print the cookie values directly in the terminal.
