Window Stats

English | 中文

A DeepSeek Harness web plugin that shows every session's conversation progress and token usage at a glance.
All-windows overview · session analysis · cost estimation · token heatmap.
100% read-only and local — no outbound requests, no session writes.

What this plugin provides

Installing this bundle adds a cross-session observability surface to every session of the target dsh profile. It reads the official tokenUsage / sessionStats / contextPressure / contextBreakdown projections (plus a tokenHistory projection it registers itself), so no host service or new RPC is required beyond that one projection unit.

Surface	What it shows
窗口统计 view tab	One row per session: status, turns/steps, input/output tokens, cache-hit ratio, context occupancy, duration, cost, last activity — with sort / filter / group-by-workspace / model & currency selectors, and a right detail panel (token buckets, context composition, timing, heatmap).
会话分析 view tab	Time-range analysis (presets + custom) of the current session: token trend chart, tool-type duration distribution (donut + bars), and per-turn task summaries.
Sidebar footer summary	Always-visible running count, total tokens, and cost.
Right overview drawer	Collapsed by default; expands to a running-sessions + top-token-consumers + recent-activity panel with click-to-open.

Data source

Displayed	Source
turns / steps / wall times	sessionStats projection
input / output / cache tokens	tokenUsage projection
context occupancy / composition	contextPressure + contextBreakdown projections
per-day token history (heatmap)	tokenHistory projection (registered by this plugin)
status	SessionSummary.running / pendingInteraction / completed

Cost is estimated from DeepSeek's official pricing (V4-Flash / V4-Pro, cache-hit / cache-miss / output priced separately) with USD / CNY / EUR / GBP / JPY switching.

Install

Requires the dsh CLI (install DeepSeek Harness).

# from GitHub (recommended)
dsh plugin --profile web add github:wellorbetter/dsh-plugin-window-stats

# or from a local checkout
dsh plugin --profile web add ./dsh-plugin-window-stats

Restart the profile (dsh web) after installing. The plugin is a bundle: it declares dsh.bundle.patch, so dsh plugin reconciles it into the profile's dsh.profile.bundles automatically. It ships pre-built JavaScript (lib/), so a GitHub install needs no build step or allowBuilds permission.

Use

After restarting dsh web:

• Sidebar — the footer shows running count + total tokens + cost at all times.
• 窗口统计 tab — open any session and click the tab to see every session's progress, tokens, and cost; click a row for a rich breakdown; use the toolbar to sort / filter / group / switch model & currency.
• 会话分析 tab — analyze the current session over a time range, by tool type, with a token trend chart and task summaries.
• Right drawer — click the edge handle to expand the running / top-tokens / recent overview, click any row to open it.

Development

pnpm install
