DeepSeek-Reasonix

Why we included this project

Reasonix is a terminal-first coding agent that treats long sessions as the normal case. Everything from model providers to plugins is declared in a TOML config rather than hardcoded, and the whole thing ships as a single static Go binary. The design is built around DeepSeek's prefix cache: it keeps a stable environment summary and prunes stale tool output before compaction, which holds token costs down while you leave it running. Any OpenAI-compatible endpoint can be added as a config entry, and you can run two models together as executor and planner in separate cache-stable sessions. The same local engine powers a CLI/TUI, a desktop app, and a VS Code extension, with MCP servers and an extension protocol for adding tools and sidecars, and the docs are unusually thorough for teams that want the engineering details.
