dsh-sidebar-panel-collapse
Adds a collapse toggle above the DSH sidebar panel list. One click hides the whole
panel block (MUV 表格 / 插件 / 插件市场 / 技能 / 归档会话 / 自动化任务 / 上下文洞察 /
记忆系统 / 更多) so the workspace list below it gets the vertical space.
Nothing else changes: the sidebar itself stays, the collapse state is remembered
per browser, and the workspace area simply grows from one row-height section up.
What it looks like
Expanded — the toggle sits right under 「新会话」, above 「MUV 表格」:
expanded
Collapsed — every panel entry row is gone and 工作区 fills the height:
collapsed
Install
dsh plugin --profile web add dsh-sidebar-panel-collapse
Or from a checkout of this repository:
dsh plugin --profile web add github:Sunday530/dsh-sidebar-panel-collapse
Restart DeepSeek Harness once after installing so the bundle row is composed into
the profile. In the plugin market card you can toggle it off/on at any time.
How it works
The browser half (lib/client.js) registers one client bundle:
- Injects a single
<style> element keyed dsh-sidebar-panel-collapse/toggle.css.
All hiding rules key on html[data-dsh-sidebar-panel-collapsed="1"], so the state
lives in one attribute on <html> and the rules are trivially reversible.
- Inserts a 20px-high chevron button as a sibling of the sidebar's panel
<nav>
(nav[class*="_panelList"]), directly under the new-session button. The shell's
React tree never removes it, because it is not part of that tree; a
MutationObserver re-attaches it if the sidebar is re-rendered.
- Marks any plugin entry button that skips the
sidebar.panellist slot and mounts
itself directly into the sidebar column (dshpc-extra), plus attribute-based rules
for the plugins that stamp a stable data attribute on their row
([data-dsh-muv-entry], [data-dsh-mnemon-entry], [data-dsh-vr-entry],
[data-dsh-ctx-entry]). Without this, "collapse" would only hide the slot-based
rows and leave the out-of-slot ones behind.
- Persists the choice in
localStorage under dsh-sidebar-panel-collapse:collapsed
(and migrates the older dsh-panel-collapse:collapsed key once).
The node half (lib/index.js) is intentionally a no-op cordis plugin — it exists only
so the package is a valid dsh.bundle row. It exports a named apply because cordis
rejects a module that has neither an apply export nor a callable default
(invalid plugin, expect function or object with an "apply" method, received object).
Notes
- Selectors match CSS-module class names by their stable suffix (
_panelList,
_newSession, _collapsed) rather than the hashed whole name, so a rebuild of the
shell does not break the plugin.
- The toggle is hidden while the sidebar is in its 56px rail (
_collapsed), because
the shell already hides the panel list there.
- The plugin never touches the shell's own collapsed state or width — it only hides
the panel-entry block.
- Tested against DSH release
0.2.1-rc.5.
