DeepSeek Harness(dsh) for VS Code

English · 简体中文

A Cursor-like AI coding experience inside VS Code — powered by your own DeepSeek Harness (DSH) agent.

Embeds the full DSH web UI in the VS Code auxiliary sidebar: every window automatically starts and owns a local dsh web service (cwd = current workspace), so your modules, skills, MCP servers, credentials and sessions all just work. On top of that it adds the IDE integration layer:

• Chat in the sidebar: Ctrl+Alt+B opens it; copy/paste/context menu, file jumps and theme following are all native
• Context attachment: right-click a file / selection / folder / Problems to append a compact link to the DSH draft — source text is never pasted, nothing is ever auto-sent
• DSH Changes review: workspace edits pushed by DSH land in a dedicated tree with diff / accept / undo; every write needs explicit approval (on by default)
• @dsh chat participant: type @dsh in the native VS Code chat to talk to your local DSH session with streaming replies — zero Copilot quota (on by default)
• Advanced, opt-in: Ctrl+K / Ctrl+I inline edit, model routing into the VS Code LM picker, MCP consumption, terminal / UI bridges, FIM tab completion — every capability behind an explicit consent switch

⚠️ Compatibility

Item	Requirement
VS Code	≥ 1.106, desktop only; remote / virtual / untrusted workspaces not supported
DSH CLI	npm i -g @deepseek-ai/dsh, ≥ 0.1.0-rc.7 recommended (older runtimes auto-retry degraded, some features limited)
Node.js	auto-detected; set dsh.local.nodePath for non-standard locations

📦 Install

• Marketplace (recommended): search DeepSeek Harness (publisher Xizhi1024) in the Extensions view, or code --install-extension Xizhi1024.dsh-vs-sidebar
• VSIX: download from Releases → Extensions: Install from VSIX...

🚀 Usage

1. Press Ctrl+Alt+B — the extension starts (or reuses) the local dsh web and loads the UI
2. Select code → right-click Add to DSH Thread; the draft receives a compact file:line link, press Enter to send
3. Type @dsh + your question in the VS Code chat — replies stream from your local DSH session
4. Let DSH propose an edit through the bridge: it lands in the DSH Changes view for diff / accept / undo — nothing is written without approval

Common commands (palette, DSH: prefix): New / Switch Session · Open Session History · Restart / Stop Server · Open in Browser · New DSH Instance (Ctrl+Alt+N) · Diagnose · Restart Cleanly · Set DSH FIM API Key.
