About DeepSeek Reasonix

Reasonix (also aliased as dsnix) is a DeepSeek-native AI coding agent for the terminal — a CLI that opens a coding session in the current directory and proposes SEARCH/REPLACE edits you approve before anything hits disk. The whole loop is engineered around prefix-cache stability: because Reasonix targets DeepSeek's byte-stable cache mechanic, long sessions stay cheap (a documented real-world day of 435M input tokens hit a 99.82% cache hit rate for ~$12 instead of ~$61 without the cache). Alongside coding, the CLI ships chat, one-shot run, doctor health-check, replay, diff, and MCP wiring subcommands, plus an optional QQ channel that lets you continue an existing session remotely. A native Tauri desktop client (prerelease) mirrors the same loop with multi-tab UI and live cost/cache/token meters. The legacy TypeScript line (0.x) is in maintenance mode; active development has moved to the Go rewrite on the main-v2 branch.

Key Features

DeepSeek-native prefix-cache loop: Every layer is tuned to DeepSeek's byte-stable prefix cache — cache stability is an invariant, not a feature toggle.
SEARCH/REPLACE code mode: The agent proposes edits and nothing lands on disk until you /apply, keeping human review at every step.
Full CLI surface: reasonix code, chat, run, doctor, replay, diff, events, stats, index, mcp, and prune subcommands.
Cross-shell support: Runs on macOS, Linux, Windows PowerShell, Git Bash, and Windows Terminal with Node ≥ 22.
QQ channel: Extend an existing chat/code/desktop session as a remote QQ channel — messages route in, assistant replies route back.
Desktop client (prerelease): Native Tauri app with multi-tab UI, files-read panel, and live cost/cache/token meters over the same loop as the CLI.
Two commands, one runtime: Install once via npm and both reasonix and the shorter dsnix alias resolve to the same CLI on your PATH.

Use Cases

Individual DeepSeek subscribers who want a terminal coding agent that keeps cache hit rates near 100% across a full working day.
Cost-sensitive developers running long agent sessions who need documented case studies (~80% savings vs no-cache) before committing to a workflow.
Engineers who prefer diff-first review — the SEARCH/REPLACE code mode keeps every proposed change reviewable before /apply.
Teams evaluating open-source DeepSeek tooling as an alternative to Anthropic- or OpenAI-native coding agents.
Remote workers on QQ who want to continue a laptop coding session from their phone via the QQ channel bridge.
Prerelease adopters willing to run the Tauri desktop client with cost/cache meters for a GUI over the same loop.
