01What can it help you accomplish?
Turn the DeepSeek Harness web UI into a full IDE-style workbench: files, terminal, Git and subagents in a sidebar
Right sidebar + bottom panel dual workbench with 7 built-in tabs: file explorer + CodeMirror editor with inline image / Markdown / HTML / PDF preview, embedded browser, real terminal, Git panel, background tasks and a plugin directory
DeepSeek Harness (dsh web) users who want an IDE-grade sidebar UI without leaving the harness
Extend the DSH sidebar with custom tabs and file viewers from other plugins
New sidebar pages and file previewers registered through the `ctx.betterSidebar` service (`registerTab` / `registerFileViewer`), with the same API the built-in 7 tabs + 6 viewers use
DSH plugin developers building UI panels on top of a shared sidebar foundation
02How to install into DeepSeek Harness
Prerequisites
- DSH installed and running (`dsh web` works)
- Node.js ≥ 20 and pnpm ≥ 10
- DSH 0.1.0-rc.8 — this release pins all `@deepseek-ai/*` dependencies to `^0.1.0-rc.8`; rc.7 and earlier cannot resolve the dependencies
Installation steps
- 01
Run `dsh plugin --profile web add dsh-better-sidebar@latest`
$ dsh plugin --profile web add dsh-better-sidebar@latest
- 02
Hard-refresh the browser (Cmd/Ctrl+Shift+R) to load the sidebar — DSH hot-loads client changes, so no restart is needed unless the host half updates
Verify the integration
- Hard-refresh the browser (Cmd/Ctrl+Shift+R); the sidebar workbench appears in the DSH web UI
03DSH integration and capability boundaries
Native DSH web-profile plugin installed via the official `dsh plugin --profile web add` command, organized per the official DSH plugin spec (host/client dual-half, dual client bundles)
File workbench with inline preview
workspace files→lazy-loading directory tree + CodeMirror editor; inline preview for images, Markdown (Mermaid with strict safe rendering), HTML and PDF; drag-and-drop file/folder upload
saves go through atomic `fs.write`; uploads write files into the workspace (media/preview routes are limited to the session cwd)Real terminal (xterm.js + node-pty)
shell configuration (shell / shellArgs settable in the settings page or cordis.patch.yml)→real shell with disconnect-reconnect replay; optional `terminal_*` tools injected for the model
spawns real shell processes on the host; optionally exposes terminal tools to the modelService-first extension API (ctx.betterSidebar)
third-party DSH plugins injecting the `betterSidebar` service→custom sidebar tabs and file viewers registered via `registerTab` / `registerFileViewer`
Git panel + session-isolated dual workbench
the session's git repository and open tabs→real diff with VSCode-style diff tabs, history, right-click stage / commit / restore; layout, tabs and panels persisted per session
invokes the git CLI (stage/commit/restore) but never sets git identity
04Who is it for? When not to use it?
Good for
- DeepSeek Harness (dsh web) users who want an IDE-grade sidebar UI without leaving the harness
- DSH plugin developers building UI panels on top of a shared sidebar foundation
Not for
- The current release requires DSH 0.1.0-rc.8 — all `@deepseek-ai/*` peer/dev dependencies are pinned to `^0.1.0-rc.8`, and DSH rc.7 or earlier cannot resolve the dependencies (upgrade DSH first).
- The real terminal depends on node-pty prebuilt binaries; if your Node version has no prebuild (common on Windows), a compile toolchain such as VS Build Tools is required.
05Compatibility, maintenance and safety notes
- The current release requires DSH 0.1.0-rc.8 — all `@deepseek-ai/*` peer/dev dependencies are pinned to `^0.1.0-rc.8`, and DSH rc.7 or earlier cannot resolve the dependencies (upgrade DSH first).
- Git integration has no push/pull/fetch, there is no file watcher (manual refresh needed), and inline file-open buttons in tool output cannot be intercepted.
- The real terminal depends on node-pty prebuilt binaries; if your Node version has no prebuild (common on Windows), a compile toolchain such as VS Build Tools is required.

06Frequently asked questions
How do I install dsh-better-sidebar in DeepSeek Harness?
With DSH running (`dsh web`), execute `dsh plugin --profile web add dsh-better-sidebar@latest`, then hard-refresh the browser (Cmd/Ctrl+Shift+R) to see the sidebar. DSH hot-loads client changes, so no restart is needed unless the host half updates. Prerequisites: Node.js ≥ 20 and pnpm ≥ 10.
Is it a native DSH plugin or an MCP server?
It's a native DSH plugin organized per the official DSH plugin spec (no default export, dual client bundles) and installed into the web profile through the official `dsh plugin` CLI — not MCP. Runtime `@deepseek-ai/*` modules are provided by the web profile.
Which DSH version do I need?
The current release targets DSH 0.1.0-rc.8: all `@deepseek-ai/*` dependencies are pinned to `^0.1.0-rc.8`. DSH rc.7 or earlier cannot resolve the dependencies, so upgrade DSH first.
Can other plugins add sidebar pages?
Yes. Since v0.4.0 the plugin exposes a `ctx.betterSidebar` service; other plugins register sidebar tabs and file viewers via `registerTab` / `registerFileViewer`, using the same API as the built-in 7 tabs and 6 viewers.
What are the known limitations?
Git has no push/pull/fetch, and there is no file watcher (manual refresh). The real terminal depends on node-pty — on Windows, a build toolchain (VS Build Tools) may be needed if no prebuilt binary exists for your Node version.
