DeepSeek Harness for VS Code

Use DeepSeek Harness as a coding assistant in the VS Code sidebar.

The goal is the same kind of workflow offered by Claude Code and Codex in VS Code: keep an assistant beside your editor while you work, with the current project, file, and selection already in context.

English | 简体中文

Features

• A Claude Code/Codex-style coding assistant powered by the official DeepSeek Harness runtime, always available in the VS Code right sidebar.
• Project and editor context built in: DeepSeek sees the current workspace, active file, and selected code. Use @file, @folder, or Add Selection to Chat for explicit context.
• Native code review: open file references and tool results in the editor, then inspect individual changes or all changed files with VS Code's Diff Editor.
• Safe collaboration with unsaved code: if DeepSeek is about to modify a dirty editor buffer, the task stops before overwriting it.
• A complete task loop inside VS Code, including streaming, tool calls, approvals, follow-up questions, project sessions, and official / commands.
• Queue follow-up messages while a task runs, edit or remove them, or steer the current task immediately with Cmd/Ctrl+Enter.
• Choose Model and Reasoning Effort separately from the composer.

Install

Install the official DeepSeek Harness CLI first:

npm install -g @deepseek-ai/dsh

Then build and install the extension:

git clone https://github.com/Lixxx1/dsh-vscode.git
cd dsh-vscode
corepack pnpm install --frozen-lockfile
corepack pnpm run check
corepack pnpm run package
code --install-extension dsh-vscode.vsix

Requires VS Code 1.100 or newer and Node.js ^22.19 or >=24.

Use

1. Open a trusted project folder in VS Code.
2. Select DeepSeek Harness in the right sidebar. If it is hidden, find it under Other Views.
3. Use the key button to configure DEEPSEEK_API_KEY.
4. Choose a project, conversation, Model, and Reasoning Effort, then start working. Type / for official DSH commands, or @ to add files and folders.
