dsh for vscode / antigravity extension

[floatinghotpot]

Here is what i created: DSH 插件 for VS Code / Antigravity IDE
https://github.com/floatinghotpot/deepseek-harness-web-for-vscode.git

If DeepSeek official needs, I can donate this project for free.

Currently more than 1.4K download from Open VSX within 1 day from Antigravity IDE.

Unfortunately, not downloadable from VS Code, as it's removed by Microsoft from its VS Code marketplace for unknown reason.

If you want to install into VS Code, try download .vsix file from GitHub releases, then in vscode extension, install from VSIX:

Launch DeepSeek Harness and embed its full Web UI inside VS Code (and Antigravity, the VS Code fork) — so you can run DSH Agents and edit code in one window, sharing the same instance as your browser.

Features

• Stay in your editor — use DeepSeek Harness and write code in the same window, in VS Code or Antigravity; no more switching between the IDE and a browser tab to watch the Agent work.
• One of your Agent stack — VS Code / Antigravity let you install multiple coding-agent extensions, each powered by its own LLM (e.g. Claude Code, ChatGPT, …), and this extension is one of them: a DeepSeek Harness Agent that works side by side with the others. Run several Agents on the same task at the same time to cross-review answers and cover each model's blind spots.
• One-click start / stop — the extension manages a dsh web child process with an OS-assigned port. Entry points: activity-bar icon (sidebar launcher), status-bar button, or Command Palette.
• Embedded Web UI in an editor tab — the full DSH frontend (conversations, workspaces, settings, plugins, Goals, Workflows) renders as a regular editor tab, side by side with your files — it never overlaps the explorer tree.
• Works with the browser instance — uses your ~/.dsh by default, so sessions and settings are shared with the browser UI.
• Current folder as workspace — the DSH default project directory is the folder you have open.
• Workspace alignment — the DSH workspace anchor follows your IDE workspace: switching folders closes stale panels and starts cold, reloading the same workspace auto-restarts the server and restores the panel, and the embedded UI always shows the current folder (not the most recently active one).
• Session manager — the sidebar lists all active sessions with title and relative activity time, with inline rename and archive; an expandable Archived section keeps old sessions tidy; ＋New session opens a stacked panel bound to a fresh session, and multiple panels each hold their own conversation.
• Auto-start from the icon — clicking the activity-bar icon starts dsh for you when it is not running.
• dsh version check + easy upgrade — the launcher shows "Update available: x.y.z →" when a newer dsh exists; one click offers the right upgrade command for your install method (npx / npm global / nvm) prefilled into a terminal (24h check gate, offline-safe).
• Clipboard works — copy/paste in the embedded UI goes through a transport bridge (VS Code webviews block clipboard inside iframes; the bridge routes it via vscode.env.clipboard).
• Theme follows VS Code — the embedded UI follows your editor color theme (dark/light), live on switch (deepseekHarness.themeSync, default follow).
• Cross-platform — macOS, Linux and Windows, verified end-to-end by CI (unit tests + a real dsh spawn smoke test on all three).
• Multilingual UI — the extension chrome (launcher, overlay, status bar, commands) follows your VS Code language across 9 locales: English, 中文, 日本語, 한국어, Русский, Español, Português, Français, Deutsch.
• Security first — the server binds loopback only; the extension relays requests as plain Node requests, never weakening DSH's /api trust fence. (Note: the embedded page and its plugins are trusted — clipboard read/write is bridged to the system clipboard without a browser permission prompt, the same trust you grant the extension itself.)

Requirements

• DeepSeek Harness installed: npm i -g @deepseek-ai/dsh
• VS Code ≥ 1.90 (the extension also works in Antigravity via Open VSX)

Install

• VS Code: Visual Studio Marketplace → search DeepSeek Harness Web for VS Code
• Antigravity / Open VSX: Open VSX → same name

Usage

1. Click the DeepSeek Harness icon in the activity bar → dsh starts automatically (if not running) and the launcher sidebar shows the server status, version and URL.
2. The DSH UI opens in an editor tab once the server is ready (dsh web: http://127.0.0.1:<port>).
3. When the server is ready, the launcher offers Stop DeepSeek Harness and Open View (full-width buttons); click Update available: x.y.z → to upgrade dsh.

To make DSH use your project as its default workspace, open that folder in the window first (the launcher footer shows the active workspace).

Guys, have a try and enjoy !
