DeepSeek Harness usage statistics plugin: aggregates API usage by vendor (subscription / official API) × KPI, with a GitHub-style calendar heatmap and daily / monthly dashboards.

Distinct from dsh-usage-stats (which aggregates by workspace): this plugin uses the vendor (provider) as the primary dimension, auto-detecting message.source.provider and message.source.model from assistant/message events, and splits KPIs into tokens / cache hits / output / reasoning.

Features

Vendor dimension: auto-discovers every vendor used (e.g. huoshan, hebox, deepseek-official, tokenrhythm, opencode), with manual labels for subscription / official API and aliases (persisted to a KV unit under $DSH_HOME/storages).
KPI cards: total tokens (input / cache hit / output / reasoning breakdown), cache hit rate, model calls, turns, sessions, vendor count, with a multi-color token composition ratio bar.
53-week heatmap: GitHub-green style, intensity by daily model calls; click a vendor chip to filter; hover for per-vendor and per-token details.
Trend line chart: Token / Calls dual-axis trend, per-day by default and per-hour for "today" (hourly aggregation).
Vendor model drilldown: click a vendor row to expand its per-model consumption.
Daily detail: per-day tokens / cache / output / reasoning / hit rate / turns (last 30 days).
Monthly summary: all history aggregated by month.
Vendor KPI table: sorted by total tokens, with hit rate, model count, type badge; click a row to drill into models.
Time presets: today / 7d / 14d / 30d / 90d / all.
Cost estimation: set a per-million-token unit price per vendor to see an estimated fee column.
CSV export: export daily / monthly / vendor tables to CSV.
Health / performance cards: average TTFT (time to first token), generation speed (t/s), peak context size, request error rate, and total model / tool wall time, aggregated from DSH's sessionStats projection.
Range switching, animations, light/dark theme adaptation.

Data source

All data comes from DSH durable session logs: assistant/message events carry usage (token accounting) and message.source.{provider,model} (vendor/model provenance).
Token accounting (consistent with DSH): inputTokens = uncached input, cacheReadTokens = cached input, outputTokens = output, reasoningTokens = reasoning, cacheWriteTokens = cache write.
Cache hit rate = hits / (hits + uncached input) × 100%.
History is backfilled automatically on activation; data survives plugin uninstall / restart.

Install

This is a standard DSH community plugin package (declares dsh.bundle manifest + web client half).

From GitHub (recommended)

dsh plugin --profile web add "github:kirigayakazima/dsh-usage-vendor-stats"

Refresh the page after install — no manual config, no restart.

Manual registration (local development)

Place this directory anywhere and create a symlink pointing to it under $DSH_HOME/profiles/node_modules/ (use a junction on Windows):

New-Item -ItemType Junction -Path "$env:DSH_HOME\profiles\node_modules\dsh-usage-vendor-stats" -Target "<absolute path to this dir>"

Add a line to $DSH_HOME/profiles/web/cordis.patch.yml:
```
- insert:
    - id: usage-vendor-stats
      name: dsh-usage-vendor-stats
```
The user patch layer hot-reloads: save and refresh the page.

Usage

Open Settings (sidebar footer) and find the API Usage Stats page, or click the 📊 Usage Stats entry in the sidebar footer to open the fullscreen panel.
Heatmap color = daily call count; click a vendor chip or table row to filter / drill down.
In Vendor Management, set each vendor's alias and type (subscription / official API), and optionally a per-million-token unit price for cost estimation.

Architecture

Host half (lib/index.js): scans durable session logs and aggregates usage (assistant/message.usage + message.source), listens to session/event for live folding; serves data routes via the webServer service:
- GET /api/usage-vendor-stats — stats snapshot (vendors / models / daily / monthly / hourly / totals)
- POST /api/usage-vendor-stats/vendor — set vendor alias, type, and unit price
Client half (lib/client.js): window.__ModuleLoader__ factory-format browser bundle, registering the API Usage Stats settings page (settings.section slot), a sidebar footer entry (sidebar.footer.action), and a fullscreen panel (shell.overlay).

Development

Editing lib/index.js / lib/client.js takes effect after a page refresh (client bundle loads with the page); host-half changes require a DSH restart.
The plugin has no third-party runtime dependencies: the host half uses only Cordis services, the client half only React (provided by the module table).

DeepSeek Harness 用量统计插件：按厂商（订阅 / 官方 API）× KPI 聚合 API 使用量，带 GitHub 风格日历热力图、趋势折线图与日 / 月 / 小时统计看板。

区别于 dsh-usage-stats（按工作区统计）：本插件以**厂商（provider）**为第一维度，自动识别 assistant/message 事件里的 message.source.provider 与 message.source.model，拆分 token / 缓存命中 / 输出 / 推理等 KPI。

功能

厂商维度：自动发现所有使用过的厂商（如 huoshan、hebox、deepseek-official、tokenrhythm、opencode），可手动标记为「订阅 / 官方API」，设置别名（持久化到 $DSH_HOME/storages 的 KV 单元）
KPI 卡片：总花费 Token（输入 / 缓存命中 / 输出 / 推理分项）、缓存命中率、模型调用次数、回合数、会话数、厂商数量，附多色 Token 构成比例条
53 周热力图：GitHub 绿色风格，颜色深浅按当日模型调用次数；点击厂商筛选后仅统计该厂商；悬停查看按厂商明细与 Token 明细
趋势折线图：Token / 调用双轴趋势，默认按日；选「今天」时按小时展示（小时级聚合）
厂商模型钻取：点击厂商行展开该厂商的逐模型消耗
每日明细：近 30 天逐日 Token / 缓存 / 输出 / 推理 / 命中率 / 回合
每月汇总：全部历史按月聚合
厂商 KPI 表：按总 Token 排序，含命中率、模型数、类型标签；点击行钻取模型
时间预设：今天 / 7 天 / 14 天 / 30 天 / 90 天 / 全部
费用估算：为每个厂商设置每百万 token 单价，即可看到折算的预估费用列
CSV 导出：每日 / 每月 / 厂商表格均可导出 CSV
健康度/性能卡片：平均首字延迟（TTFT）、生成速度（t/s）、峰值 Context、请求错误率、模型/工具总耗时，聚合自 DSH 的 sessionStats 投影
时间范围切换、动画、亮暗主题自适应

数据说明

数据全部来自 DSH 持久化会话日志：assistant/message 事件携带 usage（Token 记账）与 message.source.{provider,model}（厂商/模型来源）
Token 统计口径（与 DSH 一致）：inputTokens 为未命中输入，cacheReadTokens 为缓存命中输入，outputTokens 为输出，reasoningTokens 为推理，cacheWriteTokens 为缓存写入
缓存命中率 = 命中 /（命中 + 未命中输入）× 100%
插件激活时自动回填全部历史会话；插件卸载 / 重启后数据不丢

安装

本插件是标准的 DSH 社区插件包（声明 dsh.bundle manifest + web client 半）。

从 GitHub 直接安装（推荐）

dsh plugin --profile web add "github:kirigayakazima/dsh-usage-vendor-stats"

安装后刷新页面即可，无需手动改配置、无需重启。

手动注册（本地开发）

把本目录放入任意位置，并在 $DSH_HOME/profiles/node_modules/ 下创建指向本目录的符号链接（Windows 用 junction）：
```
New-Item -ItemType Junction -Path "$env:DSH_HOME\profiles\node_modules\dsh-usage-vendor-stats" -Target "<本目录绝对路径>"
```
在 $DSH_HOME/profiles/web/cordis.patch.yml 添加一行：
```
- insert:
    - id: usage-vendor-stats
      name: dsh-usage-vendor-stats
```
用户 patch 层会被热重载：保存后刷新页面即可。

使用

打开设置（侧边栏底部）找到「API 用量统计」页，或点击侧边栏底部的「📊 用量统计」入口打开全屏面板
热力图颜色 = 当日调用次数；点击厂商 chip 或表格行可筛选 / 钻取
在「厂商管理」里给每个厂商设置别名与类型（订阅 / 官方API），可选设置每百万 token 单价用于费用估算

架构

Host 半（lib/index.js）：扫描持久化会话日志聚合用量（assistant/message.usage + message.source），监听 session/event 实时折叠；通过 webServer 服务注册数据路由：
- GET /api/usage-vendor-stats — 统计快照（厂商 / 模型 / 日 / 月 / 小时 / 汇总）
- POST /api/usage-vendor-stats/vendor — 设置厂商别名、类型与单价
Client 半（lib/client.js）：window.__ModuleLoader__ 工厂格式的浏览器 bundle，注册设置面板「API 用量统计」页（settings.section 槽位）、侧边栏底部入口（sidebar.footer.action）与全屏面板（shell.overlay）。
