Reasonix

A config- and plugin-driven harness — a single static Go binary, tuned around DeepSeek's prefix cache so token costs stay low across long sessions.

Features:

• Config-driven. Providers, the agent, enabled tools, and plugins are all declared in reasonix.toml. No hardcoded models.
• Multi-model & composable. DeepSeek (flash/pro) and MiMo ship as presets; any OpenAI-compatible endpoint is a config entry, not new code. Optionally run two models together (executor + planner) in separate, cache-stable sessions.
• Plugin-driven. External tools run as subprocesses over stdio JSON-RPC (MCP-compatible). Built-in tools self-register at compile time.
• Zero-friction distribution. CGO_ENABLED=0 single binary; cross-compile to six targets with one command. The only dependency is a TOML parser.
