dsh-avatar-top

English | 中文

Moves the left sidebar's account avatar (which is also the Settings launcher) out of the bottom strip, so the session list gains the space back. Placement, height and spacing are adjustable from a card on the Plugins page; inline brand row costs zero vertical space.

Tested against DeepSeek Harness 0.2.1-rc.2 (desktop, Windows).

What it does

DSH pins a footer at the bottom of the left sidebar: the account row (头像 + 账号名) sits next to sidebar.footer.action, where plugins such as dsh-cost-meter mount their own widgets.

This plugin moves only the account row:

• The footer becomes display: contents, so its two children join the sidebar's flex column; the account row is then reordered while _footerActions keeps its default order and stays pinned at the bottom. (Moving the whole footer would drag other plugins' widgets along — that was a real bug in 0.2.1.)
• Four placements: top, below the brand row, below New Session, or inline inside the brand row (Windows desktop; position: absolute at the free right end, zero vertical cost).
• Three heights: full 44px, compact 32px, avatar only 28px (hides the account name and shrinks the avatar to 20px).
• Spacing 0–24px, and an on/off switch that restores the stock layout without uninstalling.

Changes apply immediately — the browser half subscribes to the settings document and rewrites the stylesheet. Settings persist in the profile's cordis.patch.yml.

Install

dsh plugin add dsh-avatar-top

Restart DSH once after installing (the client bundle and package metadata are read at host start). Then open Plugins → dsh-avatar-top to configure it.

Git install works too, e.g. dsh plugin add git+https://github.com/<owner>/dsh-avatar-top.

Self-check: the plugin serves its current stylesheet at /dsh-avatar-top.css (public, read-only), so a wrong layout can be diagnosed without a session:

http://127.0.0.1:<dsh-port>/dsh-avatar-top.css

How it works

Injection channel

The Host contributes one structured style row through webserver/index-inject:

ctx.on('webserver/index-inject', (table) => {
  table.push({ kind: 'style', text: cssFor(readOptions(config)) })
})

Both shells render that row:

Shell	Where the page comes from	How the row arrives
Browser / dsh web	the SPA dist server answers the index over HTTP	renderIndex() renders the rows into the HTML
Desktop app	Electron serves dsh-web-frontend/dist/index.html itself over its dsh-app:// scheme	the Host's injection table is handed to the page over IPC after startup; the page-side interpreter appends style rows to <head>

ctx.webServer.tapIndex() would only cover the HTTP shell; the desktop window never calls it.

The desktop snapshot is taken at Host start, so the browser half also applies the stylesheet live (<style id="dsh-avatar-top-live">, appended after the boot row, so it wins) and the boot row only prevents a flash on first paint.

The rule

The sidebar is a flex column; placement is pure order, and selectors key off the stable CSS-module class-name suffixes (_root, _footArea, _settingsArea, _trigger, _label, _avatar, _logoRow, _newSession, _panelList) rather than the per-build hash prefix.

html:not([data-platform='darwin']) [class*='_root']:not([class*='_collapsed']) > [class*='_footArea'] {
  display: contents;
}
… > [class*='_footArea'] > [class*='_settingsArea'] {
  order: -1;
  margin-bottom: 4px;
}

• macOS keeps its traffic-light strip layout (:not([data-platform='darwin'])).
• Collapsed rails are left untouched (on Windows the footer is display:none there anyway).
• inlineBrand lifts the button out of the flow (top: 8px; right: 12px; z-index: 3) and forces the avatar-only shape. On non-Windows shells it falls back to top.

Settings plumbing

Config declares four volatile() fields (user settings, not deployment config), so the Host serves the avatar-top namespace (the loader row id). The browser half binds it through ctx.configForms.get('avatar-top'), writes through config.set() / config.unset() (which reach remote.settings.mutate), and registers its card into the plugins.bundle.config keyed slot under the package name.

Known limits

• Only the account row moves. Plugins that mount into sidebar.settings (instead of sidebar.footer.action) would ride along; no shipped plugin does that today.
• Layout depends on ui-sidebar's flex column. If upstream switches the footer to absolute positioning or moves it out of the column, the rules become no-ops (no errors, no misplacement).
• inlineBrand needs the Windows titlebar (html[data-windows-titlebar]), where the collapse toggle lives in the native titlebar. Elsewhere it falls back to the top placement.
• The diagnostics route is public and read-only; it returns this plugin's CSS text only.

Development

npm install      # @deepseek-ai/schemastery, for the tests' host-side import
node --check lib/index.js
node --check lib/client.js
npm test

The smoke test covers the schema defaults and rejections, volatile-ref and plain-value inputs, the full placement × height × spacing matrix, row de-duplication, the diagnostics route, a regression assertion that _footerActions is never reordered (so cost meters and friends stay at the bottom), and byte-equality of the two CSS generators across 120 option combinations.

lib/client.js is a hand-written bundle in the DSH client-module format (window.__ModuleLoader__.load); it has no build step.
