DSH Better Sidebar: Full Workbench for DeepSeek Harness
A plugin that turns the DeepSeek Harness sidebar into a full workbench: file explorer, code editor, terminal, Git, browser, and side chat — all in one panel.
DSH Better Sidebar is an open-source plugin for DeepSeek Harness (DSH) that replaces the minimal default sidebar with a full development workbench. It adds a file explorer with a CodeMirror editor, an embedded multi-tab browser in a sandboxed iframe, a real terminal (xterm.js + node-pty) with reconnect replay, a Git panel with visual two-way diff and commit/revert controls, a Codex-style side chat thread that runs on the main session's full context, and a sub-agent task view with live output and kill controls. Layout is dual-pane — right sidebar plus bottom panel — with tabs draggable between panes or tearable into floating windows. The plugin exposes a `betterSidebar` API so any third-party plugin can register its own tabs; the ecosystem already has 28+ extensions. Released a month ago and already has 3 200+ stars.
Why a vibe-coder should care
If you work in DSH all day, you no longer need a separate terminal, file manager, or browser — everything lives in the sidebar without context switching.
How to install
Copy this and send it to your agent — Claude Code, Codex, any of them:
Install the dsh-better-sidebar plugin from https://github.com/omdsh-dev/DSH-better-sidebar — follow the README (three steps: `dsh plugin --profile web add dsh-better-sidebar@latest`, approve builds with `pnpm approve-builds --all`, hard-refresh browser), ask me if anything fails.
No extra compute required — installs as a plugin in DSH. Node.js 20+ and pnpm 10+ needed.
