Mobile / small-tablet UI optimizer for the DeepSeek Harness Web GUI.

The stock Web shell is a three-column desktop layout. Under a phone-width viewport the sidebar rail, the 188 px settings nav, and the hover-only tool-row controls become cramped or unreachable. This plugin reshapes the shell below a max-width: 820px breakpoint without touching any upstream code — it is a pure client (browser) plugin: a <style> block plus a small React overlay.

Features

• Drawer sidebar — below 820 px the sidebar becomes a left drawer. There are two entries: on session pages an in-flow "expand sidebar" button is injected next to the official top-bar "Session log" button (no overlay, no obstruction); on pages without a conversation header (the home screen) a floating action button (FAB) in the top-right corner takes over. The two are mutually exclusive — once the top-bar button exists, the FAB yields. A backdrop (over the conversation only) and Esc close it, and it auto-closes on session switch.
• Full-screen settings sheet — the settings dialog (a 188 px nav rail + content on desktop) becomes a full-screen sheet with a top title + horizontally scrollable section tabs, an absolute close button, and safe-area insets.
• Settings entrance animation — mask fade + panel slide-up; gated by prefers-reduced-motion.
• Details panel as a bottom sheet — the tool-call details column (hidden on small screens by default) becomes a slide-up bottom sheet driven by the layout's data-details-collapsed state.
• Tool-row "Inspect" button — revealed (it is hover-only on desktop) and enlarged to a 32 px touch target on small screens.
• Safe areas & touch polish — env(safe-area-inset-*), 16 px input font, touch-action: manipulation, denser composer spacing.
• Upgrade-resistant selectors — targets stable attributes ([role="dialog"][aria-modal="true"]:has(>nav), [data-shell-overlay]) and CSS-module local-name suffixes ([class*="_options"]) instead of hashed class names, so it survives DSH frontend rebuilds.

Note on the right sidebar: 0.1.5 removed the details column and introduced the right sidebar. On phone widths this plugin docks that column ([data-rightbar-col]) as a bottom sheet, so the official right-sidebar toggle opens it over the chat instead of squeezing the conversation column. The settings and drawer features are fully usable now.

Compatibility

• Declared target: DSH 0.1.5-rc.2 (dshTarget in package.json); previously declared 0.1.3-alpha.2.
• 0.1.5 reworked the AppFrame: the details column is gone and the children are now sidebar / center / rightbar / overlay. Only the rightbar column carries a data attribute ([data-rightbar-col], with data-rightbar-collapsed / data-rightbar-fullscreen / data-rightbar-instant on the frame); the center column has none, so it is matched by its CSS-module suffix [class*="_centerCol"]. The previous positional selectors (*:nth-child(2) / *:nth-child(3)) and the data-details-collapsed flag no longer exist.
• ctx.layout.closeDetails() was removed upstream and its call was dropped; ctx.slots, ctx.layout.toggleSidebar, ctx.timeout, and ctx.effect were re-verified present in the installed 0.1.5-rc.2 runtime.
• Visual behavior still needs a phone-width E2E pass on this exact version.

Install

Pure ESM, no build step, no install scripts — nothing executes at install time.

dsh plugin --profile web add github:raomaiping-hash/dsh-client-ui-mobile
# pin a commit for reproducibility:
dsh plugin --profile web add github:raomaiping-hash/dsh-client-ui-mobile#<sha>

Then restart your DSH Web process and open the GUI on a phone-width viewport (or resize the browser ≤ 820 px).

Manual / tarball

dsh plugin --profile web add ./dsh-client-ui-mobile-0.1.0.tgz   # from pnpm pack

Uninstall

dsh plugin --profile web remove dsh-client-ui-mobile

Then restart DSH.

How it works

• The host half (index.js) is an empty apply() — it only exists so the loader mounts the package.
• The browser half (client.js) is loaded via package.json's dsh.client (exports["./client"]). It injects one <style> tag, registers a MobileChrome component into the shell.overlay slot (floating entry + backdrop), and a small card into settings.general.item (an "installed" notice).
• Everything is scoped to @media (max-width: 820px); the desktop layout is untouched.

Threat model & scope

• This is a UI-only plugin: no host routes, no file access, no network, no settings persistence. It reads ctx.layout (sidebar/details toggles) and ctx.slots; it writes only DOM nodes and a <style> tag, all torn down on stop/update.
• The restricted execution environment is not a security boundary; only install plugins from sources you trust. Pin a commit hash for reproducibility.

Develop

git clone https://github.com/raomaiping-hash/dsh-client-ui-mobile
cd dsh-client-ui-mobile
node --check client.js        # syntax
node tests/smoke.mjs          # packaging integrity

Because the plugin is plain JS served directly by the DSH client-module host, editing client.js in an installed profile and refreshing the page picks up the change via the client-HMR poll — no rebuild needed.
