📦 Installation

1. Install DeepSeek Harness (DSH)

First check whether DSH is already installed:

dsh --version

If the command prints a version number, DSH is ready — go to the next step. If the command is not found, install it by OS:

macOS

Install Node.js 20 or later, then install DSH:

brew install node
npm install -g @deepseek-ai/dsh

Windows

Install Node.js LTS in PowerShell:

winget install OpenJS.NodeJS.LTS

Reopen PowerShell after installation, then install DSH:

npm install -g @deepseek-ai/dsh

Run dsh --version again to confirm DSH works.
