dsh-width-tiers

A client plugin for the DeepSeek Harness Web GUI that adds chat content width tiers with a floating picker button (bottom-right, above the composer): 标准 / 中等 / 宽 / 超宽 / 全宽 / 自定义 (standard / medium / wide / ultra / full / custom).

Why

The DSH Web app caps the message column — and every table inside it — at --dsh-chat-content-width (0.1.7 default clamp(680px, column × 0.64, 920px)), no matter how wide your window is, so wide tables always need horizontal scrolling.

This plugin sets the width per tier through 0.1.7's native width axis (--dsh-chat-user-width + the app's dsh.conversation.contentWidth preference), letting the app clamp every value to "column − 176px handle budget" — so the built-in drag handles keep working:

On narrow windows wider tiers are clamped to the available column, so nothing overflows under the sidebar.

The choice persists in localStorage and is restored on the next visit; the menu highlights the current tier, and the button's five level-bars show it at a glance (all lit for custom). Dragging one of 0.1.7's native edge handles switches the picker to the custom tier — the plugin stands aside for native drags.

Install

dsh plugin --profile web add dsh-width-tiers

The bundle patch then inserts the dsh-width-tiers loader entry itself — no manual cordis.patch.yml edits needed.

Restart dsh web (the plugin loads at boot) and hard-refresh the page (Ctrl+Shift+R). A round button with five bars appears at the bottom-right.

Installing from a local checkout: dsh plugin --profile web add file:/path/to/dsh-width-tiers. Local-development gotcha: file: dependencies are copied into the profile's node_modules (pnpm does not symlink them). After editing the plugin source, re-sync the copy (e.g. rsync -a --delete --exclude .git /path/to/dsh-width-tiers/ ~/.dsh/profiles/web/node_modules/dsh-width-tiers/) or re-install after removing it, then restart dsh web and hard-refresh.

Usage

• Click the round button → pick a tier; the current one is highlighted.
• full collapses the sidebar to the icon rail through the app's own toggle — it is never force-hidden or locked: click a rail icon any time to expand it, and it stays expanded.
• Non-standard tiers also close the details panel (re-closed automatically if reopened); standard leaves everything to the app.

Language

All picker copy (tier labels, button aria-label and title) follows the app's Settings → Language (中文 / English), through the app's own locale service. Switching the language re-renders the button and menu immediately; when no explicit language is chosen the app falls back to the browser's language, and Chinese is the last resort. No plugin-side setting needed.

How it works

• The element that defines --dsh-chat-content-width is located at runtime (the first element whose computed value is non-empty) and the tier is applied as an inline override — no hashed class names, so it survives bundle upgrades.
• Panels are driven through the layout service (ctx.layout), never by simulating clicks.
• The sidebar is only ever collapsed by the full tier; returning to standard restores it only if this plugin collapsed it.
• Dictionaries are registered with the app's locale service (ctx.locale.register / bind) and re-rendered through its change subscription, so the copy always matches the app's active language.

Limitations

• Content width cannot exceed the window: on a narrow window, wider tiers are capped by the available column. Use full (which also collapses the sidebar) for the maximum.
• Requires the DSH Web client plugin system (dsh ≥ 0.1.0-rc.x with a web profile).

Uninstall

dsh plugin --profile web remove dsh-width-tiers

then restart dsh web.
