⭐ Like DSH Sidebar? Give it a Star on GitHub! It helps more people find the project.
Bring DeepSeek Harness into the same place you write code. dsh-vscode gives DSH a Claude Code/Codex-style right sidebar that already understands your project, active file, and selected code.
Ask DeepSeek to inspect, change, and verify code without switching between your editor, terminal, and a separate chat window.
👋 I built this because I wanted DSH right beside my editor. If that sounds useful to you too, give it a try! I'd love to hear how it fits into your workflow.

Official DSH inside VS Code. Sessions, streaming responses, tool calls, approvals, and follow-up questions run through the official DSH runtime.Project-aware editor context. The active file, selected code, and@file
or@folder
references travel with your prompt.Session controls where you need them. Switch Permission and Plan modes, choose Model and Reasoning Effort, or steer an active task.Native review and safe revert. Review changes in VS Code's Diff Editor, Keep or Revert edits, and stop DSH before it overwrites a file with unsaved changes.Extend DSH from the sidebar. Discover and manage Tools, Skills, MCP integrations, Memory, and Agent Hooks loaded by DSH.
Install the official DeepSeek Harness CLI:
npm install -g @deepseek-ai/dsh
Then choose the extension channel that fits you:
Open Extensions in VS Code, search for DSH Sidebar, and select Install. You can also install it from the VS Code Marketplace.
To try features already available on main
but not yet published to the Marketplace, build and install the latest VSIX:
git clone https://github.com/Lixxx1/dsh-vscode.git
cd dsh-vscode
pnpm install --frozen-lockfile
pnpm run package
In VS Code, run Extensions: Install from VSIX... from the Command Palette and select dsh-vscode.vsix
. Development builds move faster and may be less stable; pull the latest changes and rebuild the VSIX to update.
Requires VS Code 1.100 or newer and Node.js ^22.19
or >=24
.
Installing community runtime plugins also requires pnpm
on your PATH.
