A DeepSeek-native AI coding agent for your terminal.
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 ships as a preset; 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.
- **Cache-aware context maintenance.** Startup injects a small stable environment
summary, stale tool output is snipped/pruned before summary compaction, and the
built-in tool schema contract is documented for regression review.
- **Zero-friction distribution.** `CGO_ENABLED=0` single binary; cross-compile
to six targets with one command. The only dependency is a TOML parser.
## Install
Choose the path that matches how you want to use Reasonix. The CLI/TUI,
desktop app, and VS Code extension all use the same local Reasonix engine.
### Path A: CLI / TUI
Install the native binary through npm on any supported platform, or use
Homebrew on macOS:
```sh
npm i -g reasonix # any OS; pulls the prebuilt native binary
brew install esengine/reasonix/reasonix # macOS
```
Prebuilt archives (`darwin|linux|windows × amd64|arm64`) and `SHA256SUMS` are on
every [GitHub release](https://github.com/esengine/DeepSeek-Reasonix/releases).
### Path B: Desktop app
Use the [official download page](https://reasonix.io/?download=desktop#start)
for the latest desktop build.
| Platform | Package | Architecture |
| --- | --- | --- |
| macOS | Universal `.dmg` or `.zip` | Apple Silicon / Intel |
| Windows | Installer `.exe` or portable `.zip` | x64 / ARM64 |
| Linux | `.deb` or `.tar.gz` | x64 |
Windows installers are code-signed through [SignPath.io](https://signpath.io/)
with a free certificate provided by the [SignPath Foundation](https://signpath.org/).
### Path C: VS Code extension
Complete Path A first. The extension does not bundle the CLI; it starts your
local `reasonix acp` backend and adds native chat, editor context, tool-call
approvals, model selection, and workspace sessions.
- **VS Code:** [install from Visual Studio Marketplace](https://marketplace.visualstudio.com/items?itemName=SivanLiu.reasonix-agent)
- **VSCodium / Eclipse Theia:** [install from Open VSX Registry](https://open-vsx.org/extension/SivanLiu/reasonix-agent)
- **Extension ID:** `SivanLiu.reasonix-agent` · [source and usage guide](https://github.com/SivanCola/reasonix-vscode)
### Path D: Build from source
```sh
git clone https://github.com/esengine/DeepSeek-Reasonix.git
cd DeepSeek-Reasonix
make build # -> bin/reasonix(.exe)
make cross # -> dist/ (darwin|linux|windows × amd64|arm64)
```
## Quick start
### CLI / TUI
These commands are for the CLI/TUI installed through Path A:
```sh
reasonix setup # configure a provider and model
reasonix # start an interactive session
reasonix run "implement the TODOs in main.go"
```
In an interactive session, run `/init` when you want Reasonix to create project
instructions.
### Desktop app
Download the installer for your platform from the
[official download page](https://reasonix.io/?download=desktop#start), install
and launch Reasonix, then configure a provider and model in the app. The CLI
commands above are not required for the desktop app.
For advanced CLI usage and configuration, see the **[CLI reference](./docs/CLI.md)**,
**[Guide](./docs/GUIDE.md)**, and
**[configuration paths](./docs/CONFIG_PATHS.md)**.

If Reasonix has been useful and you'd like to say thanks, you can. It stays a
coffee, not a contract — donations don't buy feature priority or change how
issues get triaged.
