tbckr/sgpt ? reverse-engineered prompt

Build me a terminal app that lets me talk to AI models from the command line.

I want it to feel like a handy shell helper, where I can ask normal questions, get quick answers, generate shell commands, and even ask for code snippets without leaving my terminal. It should support chatting back and forth, work nicely in interactive sessions, and let me pipe in text or files when that makes sense. It would be great if it can also handle image prompts for vision models, and let me choose between different providers like OpenAI, OpenRouter, and Gemini if available.

Please make the experience smooth for everyday use, with sensible defaults, easy setup for API keys, and commands that are simple to remember. If there are good docs or current API details to check online, go ahead and use them. Also include a way to customize prompts a bit, since I’d like to reuse the tool for different workflows.
