DeepSeek-Reasonix Ships a Terminal Coding Agent as One Go Binary

A config- and plugin-driven harness distributed as a single CGO-disabled static binary, MIT-licensed, with providers and tools declared in a reasonix.toml rather than compiled in. Plugins run as subprocesses over JSON-RPC and are MCP-compatible; any OpenAI-compatible endpoint works as a backend. The specific engineering choice worth noting is that context management is tuned around DeepSeek’s prefix cache, which is what keeps token cost flat across long sessions rather than climbing with conversation length. Distribution covers npm, Homebrew, prebuilt binaries, desktop installers and a VS Code extension. It added roughly 920 stars in a day.
