hexsecteam/worm-gpt ? reverse-engineered prompt

Build me a clean terminal chat app that talks to OpenRouter models and feels nice to use in a plain command line window.

I want a simple menu where I can set my API key, choose a model, switch the interface language, and start chatting. It should remember my settings in a config file so I don’t have to enter them every time. The chat should support automatic language detection and work well for a few common languages like English, Indonesian, Spanish, Arabic, Thai, and Portuguese.

Make the interface look polished with colors, a banner, and a typing style response so it feels interactive instead of bare bones. Let me enter my own OpenRouter model ID if I want, but also include a sensible default. Keep it lightweight and easy to run from the terminal with clear prompts and good error handling. If you need to check current OpenRouter details or docs, look them up online first.
