Twigpine/openclaude ? reverse-engineered prompt

Build me a terminal first coding assistant that works with a bunch of different AI providers, both cloud and local, and feels easy to use from day one.

I want one CLI where I can set up a model provider, save profiles, start chatting, and then use it for real coding work like reading files, searching the codebase, running shell commands, using tools and agents, and talking to MCP servers. It should stream responses live in the terminal, and have simple slash commands for common things like provider setup, onboarding, and web search. Make it feel polished and friendly, with a small playful visual touch if that fits.

It should run on Node and also include a VS Code extension for quick launch integration and theme support. If you need to check the latest docs for any provider or API details, look them up online and make reasonable choices.
