dsh-statusbar

A VSCode-style bottom status bar for DeepSeek Harness Web. Shows your conversation usage, host CPU/memory, and a live generation rate — every item configurable.

Features

• 24px bottom bar rendered via the shell.overlay seat; the app frame reserves bottom

space so the page content (sidebar settings, composer) is never covered.

• Built-in items (each individually configurable — see [Configuration](#configuration)):

- DSH brand (left) - ⧉ Tokens — estimated tokens of the current conversation (tokenMeter) - 7 轮 · 64 步 — session turns / steps (sessionStats) - LLM 14m12s · 工具调用 48.4s — accumulated LLM / tool wall time - 首 token 平均 1.3s · 129 tok/s — first-token average + decode throughput - 缓存命中 97% — prompt-side cache hit rate (tokenUsage) - 输入 7.4M tok · 输出 98.9K tok — billed input / output tokens - TPS 363 tok/s — live generation rate (liveTokenUsage; needs [dsh-live-stats])

- Host clock

• Hides the original stats line + TPS row under the composer input box (now redundant).
• Polls /dsh-statusbar/snapshot?session=<id> every 2 s.

Installation

Prerequisites: a DSH install with a web profile (e.g. the default web profile created by dsh web).

# from the GitHub repository
dsh plugin --profile web add https://github.com/Small-Miao/dsh-statusbar

# or via SSH (needs GitHub SSH access on this machine)
dsh plugin --profile web add git@github.com:Small-Miao/dsh-statusbar.git

# or from a local checkout (development)
dsh plugin --profile web add /path/to/dsh-statusbar

The command runs pnpm add in the profile, installs the bundle into ~/.dsh/profiles/web/node_modules, and appends the plugin to dsh.profile.bundles. Then restart DSH; the plugin mounts at startup and the bar appears after a page refresh.

> Manual install (no dsh plugin): pnpm --dir ~/.dsh/profiles/web add <path-or-url> > works too — the plugin is a standard dsh.bundle package.

Configuration

Settings → 状态栏: toggle each item's visibility, side (left / right), and order (number input, ascending = further left), plus a "全部重置" (reset all) button.

Config is stored host-side and persisted to dsh-statusbar-config.json next to the profile composition. HTTP: GET /dsh-statusbar/snapshot?session=<id> returns { items, catalog, config }; POST /dsh-statusbar/config accepts { id, patch } (patch = { visible?, align?, order? }, or null to clear) or { resetAll: true }.

Public API for other plugins

The host exposes a statusbar Cordis service. Other host plugins can add their own items — including live text and char progress bars:

export function apply(ctx) {
  const statusbar = ctx.get('statusbar')
  if (statusbar === undefined) return   // plugin not installed — degrade gracefully
  ctx.effect(() => statusbar.registerItem({
    id: 'my.item',          // required, unique
    order: 15,              // sort order, ascending (configurable by the user)
    align: 'right',         // 'left' | 'right'
    label: () => 'value',   // string or lazy thunk
    style: 'bar',           // 'text' (default) | 'bar'
    progress: () => 62,     // 0-100, number or lazy thunk (bar style)
    barChar: '|',           // optional, default '|'
    barTotal: 10,           // optional, default 10
    color: '#4fc1ff',       // optional label color
    tooltip: 'hint',        // optional hover text
  }))
  // also: statusbar.updateItem(id, patch) / statusbar.removeItem(id) / statusbar.list()
}

Registering a data source

For plugins that own a live value (their own metric, service readout, projection...), registerDataSource lets the status bar pull from a provide() callback on its own refresh cadence and render it as an item (text or char bar):

export function apply(ctx) {
  const statusbar = ctx.get('statusbar')
  if (statusbar === undefined) return
  ctx.effect(() => statusbar.registerDataSource({
    id: 'disk.usage',       // required, unique — also the config key
    order: 55,              // default position
    align: 'right',         // 'left' | 'right'
    style: 'bar',           // 'text' (default) | 'bar'
    barChar: '|',           // optional, default '|'
    barTotal: 10,           // optional, default 10
    refreshMs: 5000,        // optional, default 2000 — host re-calls provide() when stale
    tooltip: '磁盘用量',
    provide: async () => ({ // required — called by the host; return the latest value
      text: '磁盘 62%',
      progress: 62,         // 0-100, used when style is 'bar'
      color: '#4fc1ff',     // optional
      tooltip: 'updated hint', // optional, overrides the default tooltip
    }),
  }))
  // also: statusbar.removeDataSource(id)
}

Data sources appear in the bar and in Settings → 状态栏 exactly like built-in items (users can toggle/position them), and the host renders the last known value while a slow provide() is in flight.

Development

git clone https://github.com/Small-Miao/dsh-statusbar
dsh plugin --profile web add ./dsh-statusbar   # or symlink into the profile

• lib/index.js — host half: statusbar service, /dsh-statusbar/* HTTP routes,

node:os CPU/memory sampling, session projections (sessionStats / tokenUsage / liveTokenUsage) cached 4 s per session.

• lib/client.js — browser half (__ModuleLoader__ bundle): the bar in shell.overlay

and the settings section in settings.section.

Layout note

The reserved bottom space relies on the app frame's hashed class (.pI_x6G_frame in the current web build). If the web app is rebuilt with new CSS hashes, update that selector in lib/client.js.
