DeepSeek Harness for VS Code

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.

Features

• Work with the real DSH runtime. Sessions, streaming, tool calls, approvals, follow-up questions, and official / commands stay inside the VS Code sidebar.
• Extend DSH from VS Code. Search and install community Tools, Skills, MCP integrations, Memory, and Agent Hooks. Plugins are added to the official web profile and loaded by DSH after restart.
• Start with the right context. DeepSeek receives the current workspace, active file, and selected code. Add specific files or folders with @, or pin a selection with Add Selection to Chat.
• Control every session. Switch official Permission and Plan modes from the composer, then choose Model and Reasoning Effort independently.
• Review edits where you code. Changed files are grouped by turn with +/- line counts. Open them in VS Code's native Diff Editor, then Keep or safely Revert individual files or the full change set.
• Stay in control while DeepSeek works. Queue, edit, remove, or steer follow-up messages. If DeepSeek reaches a dirty editor buffer, the task stops before overwriting your unsaved work.

Install

npm install -g @deepseek-ai/dsh

Then open Extensions in VS Code, search for DSH Sidebar, and select Install. You can also install it from the VS Code Marketplace.
