dsh-sidebar-panel-fold

A tiny DeepSeek Harness Web UI plugin that adds a collapsible group header to the sidebar, so the global panel entries stop eating the whole column.

Collapse it and only one row is left:

▸ Menu entries

The fold state is remembered in localStorage, so it survives a reload.

Install

Option A — straight from GitHub (needs git on the machine)

Open the Harness Web UI → Plugins panel → install bundle and use

github:2646601154/dsh-sidebar-panel-fold

or from an agent session through the plugin-manager tool:

{ "action": "install_bundle", "target": "github:2646601154/dsh-sidebar-panel-fold" }

The bundle is enabled as soon as it installs. If the sidebar does not change immediately, reload the window (Ctrl+R / Cmd+R).

Option B — clone, then install the directory

git clone https://github.com/2646601154/dsh-sidebar-panel-fold.git

then point install bundle at the absolute path of the clone:

{ "action": "install_bundle", "target": "D:\\code\\dsh-sidebar-panel-fold" }

This is also what you want if you plan to edit the plugin — a directory install is linked, so changes take effect without reinstalling.

How it works (and why it is done this way)

sidebar.panellist is a plain list slot: each entry may only declare { id, order, label }, and the shipped sidebar renders every entry as a flat row inside nav[class*="panelList"]. There is no grouping API, and replacing the whole sidebar slot (shadows-shipped-ui) would throw away the session tree. So the plugin:

1. registers its own entry in sidebar.panellist with order: -1 and a localized label thunk — that is the header row;
2. marks its own glyph with data-dspf-header and paints a chevron from inside its slot component;
3. intercepts the click of that row in the document capture phase (preventDefault() + stopPropagation()), so the host's selectPanel(id) never runs — the plugin has no matching main panel, and that call would throw;
4. toggles data-dsh-panel-fold="1" on <html>; a component-scoped stylesheet hides every other panel row while it is set:

html[data-dsh-panel-fold="1"] nav[class*="panelList"] > button[class*="panelRow"]:not(:has([data-dspf-header])) {
  display: none !important;
}

Nothing else in the sidebar is touched: no DOM is written outside the component, no other plugin's entries are re-registered, and everything (attribute, listener, <style>) is removed when the plugin unloads.

Compatibility

The hide rule matches the shipped CSS-module class names by suffix (panelList, panelRow) because they carry a build hash. If a future Harness release renames them, folding silently stops working; the fix is the two suffixes at the top of client.js (PANEL_LIST_SELECTOR and the panelRow match). Issues and PRs welcome.

Written against @deepseek-ai/dsh-client-ui-sidebar as shipped in DeepSeek Harness 0.2.1-rc.2.

Layout

中文说明

在侧边栏面板列表最上方加一行「功能入口」标题行，点一下就把 插件 / 插件市场 / 自动化任务 / 上下文洞察 / SSH / MCP 连接器 整组收起，再点展开。折叠状态记在 localStorage，刷新后保持。

安装：在插件面板里用 github:2646601154/dsh-sidebar-panel-fold 直接装；或者把仓库克隆到本地后用 install_bundle 指向该目录（目录安装是软链，适合想改代码的人）。装完若侧栏没变化，按 Ctrl+R 刷新窗口。
