01What can it help you accomplish?
Run DeepSeek Harness coding sessions inside VS Code
A native sidebar workbench with streaming Markdown, thinking steps, tool calls, approvals, full session history with export/import, slash commands, and Harness-native capabilities (Todos, Skills, Goals, Plan mode, background jobs)
VS Code developers who want a first-class DeepSeek Harness workbench without installing or managing a Harness deployment
Discover, classify, and install DSH plugins without leaving the editor
A native plugin center that browses the `dsh-plugin` GitHub topic merged with Awesome DSH Plugin metadata, accepts npm/GitHub/local/tarball package specs, and installs via the official `dsh plugin --profile web add/remove` workflow
DeepSeek Harness users who want curated plugin discovery and managed installation inside VS Code
02How to install into DeepSeek Harness
Prerequisites
- A platform-specific VSIX from Releases — for example an Apple Silicon Mac requires the `darwin-arm64` package
- Nothing else: no upstream repository to clone, no Node/npm setup, and no local Harness deployment to manage
Installation steps
- 01
Download the VSIX matching your platform from the Releases page
- 02
Open the VS Code Extensions view (`Cmd/Ctrl+Shift+X`), select `...` → **Install from VSIX...** and choose the downloaded file
- 03
Reload the VS Code window when prompted
- 04
Select the **DeepSeek Harness** icon in the Activity Bar, open **Connection settings**, configure DeepSeek Official or add a relay source (or run `DeepSeek Harness: Set API Key`), then describe your task in the composer and send it

03DSH integration and capability boundaries
Native runtime — the extension bundles the official `@deepseek-ai/dsh` package, pnpm, and standalone Node 22.22.3, manages plugins via the official `dsh plugin --profile web add/remove` workflow, and needs no Harness install or start command
Native VS Code workbench
VS Code sidebar conversation UI with a composer→full DeepSeek Harness workbench; the Harness Gateway listens only on a random loopback port and the WebUI is neither served nor embedded
Complete session workflow
DSH ZIP / ChatGPT export ZIP / other agent transcripts; DSH mode switches→persistent history, create, switch, rename, fork, resume, archive/restore, export, and import sessions
changing the DSH mode opens a fresh session in the new mode and carries the previous context as a hidden digest attached to your next messageStreaming Markdown with stable rendering
streamed Markdown replies→headings, lists, tables, code blocks, copy controls, safe external links, and clickable workspace file references; streamed updates preserve disclosure state and scroll position
Harness-native capabilities and model controls
DeepSeek V4 Flash / Pro models, `off` / `low` / `high` / `max` reasoning effort, four official Agent Presets→reasoning, tool calls, approvals, structured questions, Todos, Skills, Goals, Plan mode, and background jobs
Native DSH plugin center
an npm package, `github:owner/repository`, a local path without shell metacharacters, or a tarball URL→a curated catalog read from the `dsh-plugin` GitHub topic merged with Awesome DSH Plugin metadata, category filters, installed-plugin inspection, and compatibility classification
Harness is stopped while pnpm changes that profile and is then restarted automaticallythird-party DSH plugins are trusted Extension Host dependencies and run outside the Agent sandbox
04Who is it for? When not to use it?
Good for
- VS Code developers who want a first-class DeepSeek Harness workbench without installing or managing a Harness deployment
- DeepSeek Harness users who want curated plugin discovery and managed installation inside VS Code
Not for
- One extension ID and one Marketplace product, but platform-specific VSIX files are required because the bundled Node, PTY, and sandbox packages contain native binaries. The hosted GitHub Actions matrix builds only `darwin-arm64`, `linux-arm64`, `linux-x64`, and `win32-x64`; other architectures need a self-hosted runner or local packaging.
- DeepSeek Harness is currently a Developer Preview, and this is a community-maintained `0.5.6` release pinning the official `@deepseek-ai/dsh@0.1.1-rc.2` package.
- Third-party DSH plugins are trusted Extension Host dependencies that run outside the Agent sandbox; review their source before installation. API keys stay in the extension's private Harness home and are never sent to the Webview or written to logs.

- Plugin client UI built for the upstream DSH browser application cannot be rendered generically by this native workbench and is marked **Official Web UI**; UI-only themes and layout extensions cannot affect the native workbench and their install button is disabled.

06Frequently asked questions
Do I need to install DeepSeek Harness separately?
No. The extension bundles the official `dsh` runtime, pnpm, and standalone Node 22.22.3 in each platform VSIX, and the README states that no Harness install or start command is required. You only install the VSIX.
How do I install the extension?
Download the VSIX matching your platform from the Releases page, open the VS Code Extensions view (`Cmd/Ctrl+Shift+X`), select `...` → **Install from VSIX...**, choose the file, and reload the window when prompted. For example, an Apple Silicon Mac requires the `darwin-arm64` package.
How do I connect a model source?
Select the **DeepSeek Harness** icon in the Activity Bar, open **Connection settings**, and configure DeepSeek Official or add a relay source. You can also run `DeepSeek Harness: Set API Key` for the official source.
How does the built-in DSH plugin center work?
Open the **⊞ Plugins** button in the workbench header to browse repositories read from the `dsh-plugin` GitHub topic, merged with Awesome DSH Plugin metadata. The **Installed** tab accepts one package spec — an npm package, `github:owner/repository`, a local path, or a tarball URL — installed via the official `dsh plugin --profile web add/remove` workflow.
Are third-party DSH plugins safe to install?
The README warns that third-party DSH plugins are trusted Extension Host dependencies that run outside the Agent sandbox, and instructs you to review their source before installation. GitHub-only entries without curated metadata are marked **Compatibility unknown** until their installed manifest can be inspected.
