esengine/DeepSeek-Reasonix — reverse-engineered prompt

Build me a terminal based AI coding assistant called Reasonix. I want it to run as a simple command line tool, talk to DeepSeek by default, and also let me plug in any OpenAI compatible model from a config file without changing code.

It should have a setup wizard that creates a local config, support API keys from environment variables, and let me choose models for normal work and optional planning. I want a chat mode for interactive coding help, plus a run mode where I can say things like implement the TODOs or add tests and it edits the project.

Please make it safe by asking before file changes in chat, respecting deny rules for risky commands, and keeping edits inside the current workspace. Include project memory generation, basic built in tools for reading, editing, and running commands, and a plugin system for external tools. Use Go, ship as a single binary, and make install easy through npm and Homebrew.
