deepseek-harness-zh-cn

English | 简体中文

A Chinese-first plugin that makes DeepSeek Harness reason (reasoning) and answer in Simplified Chinese by default.

Overview

This project offers two ways (choose one; the first is recommended) to turn your DSH's reasoning and output into Simplified Chinese, so Chinese-speaking users can read the trajectory and processing directly without translation overhead:

• Method 1 (recommended, simplest): copy AGENTS.md.example to ~/.dsh/AGENTS.md.
• Method 2 (plugin): install this package from npm and mount it in the profile.

Tip: this plugin's "Chinese-first" rules can also be achieved with the keep-reminder plugin — put the same rules into a project's .keep-reminder file, and customize the content freely (not limited to language).

Quick Start

Method 1: Copy AGENTS.md (recommended)

Copy AGENTS.md.example to the DSH home directory as AGENTS.md:

• Linux / macOS: ~/.dsh/AGENTS.md
• Windows: C:\Users\<you>\.dsh\AGENTS.md

# Linux / macOS
cp AGENTS.md.example ~/.dsh/AGENTS.md

On Windows, copy the file manually. Then restart dsh web (or start a new session).

Method 2: Install the npm plugin

A. Official command (backs onto pnpm; install pnpm first):

npm i -g pnpm
dsh plugin --profile web add deepseek-harness-zh-cn

B. Install with npm directly into the profile directory:

cd ~/.dsh/profiles/web    # Windows: C:\Users\<you>\.dsh\profiles\web
npm install deepseek-harness-zh-cn --save

Note: this npm install runs inside the DSH profile directory, not this plugin's project directory.

Mount it in ~/.dsh/profiles/<name>/cordis.patch.yml:

- insert:
    - id: dsh-zh
      name: 'deepseek-harness-zh-cn'

Restart dsh web.

Scope and Limitations

• Affects both the model's final answer and its reasoning (thinking) channel.
• There is no harness or DeepSeek API switch that forces the reasoning language; on technical tasks the model's reasoning_content may still be English. A fully Chinese prompt maximizes the probability but does not guarantee it.

How It Works

• Method 1: ~/.dsh/AGENTS.md is injected by dsh-agent-instructions as a <system-reminder> user message — guidance-level, lower priority than the system prompt and direct user instructions.
• Method 2: the plugin listens to the agent/pre-step waterfall and appends a <system-reminder> user message to the request batch at the first step of each turn, reinforcing the Chinese rule once per turn.

Development

Build

npm install
npm run build      # compiles src → lib/index.js

Mount locally

During development you can mount the compiled output directly via a file:// URL, with no package install. Edit ~/.dsh/profiles/<name>/cordis.patch.yml:

- insert:
    - id: dsh-zh
      name: 'file:///D:/ui-workspace/deepseek-harness-zh-cn/lib/index.js'

Adjust the URL to your checkout path.

Restart

npx @deepseek-ai/dsh web

Stop the running service first if it is already up.

Verify

# Windows
npx @deepseek-ai/dsh web --dump-config | findstr /C:"dsh-zh"

# Linux / macOS
npx @deepseek-ai/dsh web --dump-config | grep dsh-zh
