Usage statistics panel for DeepSeek Harness (DSH) Web GUI — silent background collection, per-model analytics, cost estimation and a daily-limit guard.

Features

Silent collection — hooks session events, folds every assistant message's token usage into daily buckets per provider × model; survives restarts, backfills from session logs on first run
Matches the harness's own accounting — usage is read from assistant/message (data.usage), from the last usage chunk embedded in an assistant/message / assistant/attempt stream, and from legacy assistant/chunk events; llm/retry-started closes the replacement slot so a retried attempt adds up instead of overwriting the failed one (same rule as dsh-token-meter)
Reads every session-log generation — canonical session.v<N>.jsonl.zstd (format v4, what DSH 0.2.x writes) as well as legacy session.jsonl.zstd, uncompressed .jsonl, and picks the highest generation per session directory
Dashboard in Settings → Usage: six stat cards (tokens, sessions, requests, active days, current streak, top model), a GitHub-style activity heatmap (continuous year view, weekday/month labels, hover detail card per day), a multi-series line/area trend chart (input / output / cache hit / cache write / cost, dual axes, 7d/30d switch) and a model-usage donut
Cost estimation — configurable per-model prices (input / output / cache read / cache write per 1M tokens); built-in DeepSeek list prices; models without a price are excluded from cost instead of guessed
Daily-limit guard — optional daily token / cost caps; warn mode shows a global banner, block mode aborts over-limit LLM requests before they hit the network
Bilingual (zh/en), follows the DSH theme tokens (--dsw-alias-*), ships its own icons so host icon renames cannot blank the panel, zero external runtime dependencies

Install

Desktop app (profile name desktop) — use the CLI bundled with the app:

dsh plugin --profile desktop add <path-or-package-or-github-url>

If dsh is not on your PATH (the desktop installer does not add it by default), call the bundled launcher instead — or turn the command line on from the app's own settings:

"<install dir>\resources\runtime\cli\bin\dsh.cmd" plugin --profile desktop add <spec>

Fully quit DeepSeek Harness Desktop, then start it again (the host half of a plugin only loads at boot), and open Settings → 使用统计 / Usage. The CLI forwards everything after add to pnpm, so an absolute local path, an npm name or a GitHub URL all work; the bundle layer (dsh.profile.bundles) is updated automatically. Installing from a GitHub URL builds the client bundle through the prepare script, which pnpm may hold back until you approve it under allowBuilds — the npm package needs no building.

Web profile (dsh web):

dsh plugin --profile web add dsh-usage-guard   # npm
dsh plugin --profile web add <github-url>      # or from GitHub

Restart dsh web, then open Settings → 使用统计.

Upgrading

Statistics live in $DSH_HOME/usage-stats.json. Everything in it except your prices and guard settings is derived from the session logs, and upgrading to 0.1.1 rebuilds that derived data once on first start (the day buckets it replaces were missing roughly 7/8 of the real usage — the old watermarks had already passed the end of each log, so nothing could be recovered incrementally). Expect the totals to jump to the real figures after that first start; usage belonging to session logs you have since deleted is gone for good.

Compatibility

DSH	Session log	Notes
0.2.x (desktop 0.2.0-rc.2 verified)	`session.v4.jsonl.zstd`	current target; icons come from the plugin itself because `IconXxx16` was renamed to `IconXxxOutlineRegular/Medium`
0.1.x	`session.jsonl.zstd`	host half unchanged; client panel works while `Button` / `Input` still exist

Develop

pnpm install
pnpm build          # tsdown + wrap-client → dist/client.js (host loads host/, browser loads dist/)
pnpm test           # vitest: host fold/log/route/store/guard + client rendering
pnpm verify:bundle  # loads dist/client.js the way the browser does and checks registrations
pnpm verify:parity  # replays your real session logs and diffs the fold against a transcription of dsh-token-meter's projection
pnpm check          # test + build + verify:bundle

pnpm test also replays real session logs: client/render.smoke.test.tsx renders the charts from ~/.dsh/usage-stats.json.

DeepSeek Harness（DSH）Web GUI 的用量统计面板——后台静默采集、按模型分析、费用估算、每日超限守卫。

功能

静默采集——挂钩会话事件，把每条助手消息的 token 用量折叠进天 × 提供商 × 模型桶；重启不丢，首次运行自动从会话日志回填
与宿主自己的口径一致——用量取自 assistant/message 的 data.usage、assistant/message / assistant/attempt 流里内嵌的最后一条 usage chunk，以及旧格式的 assistant/chunk 事件；llm/retry-started 会关闭替换槽，让重试的那次请求累加而不是覆盖掉失败的那次（与 dsh-token-meter 同一套规则）
认得每一代会话日志——规范的 session.v<N>.jsonl.zstd（格式 v4，DSH 0.2.x 的落盘名）、旧的 session.jsonl.zstd、未压缩的 .jsonl；同一会话目录取最高代次
仪表盘（设置 → 使用统计）：六张统计卡（tokens、会话数、请求数、活跃天数、连续天数、最常用模型）、GitHub 风格活跃热力图（连续年度视图、星期/月份标注、逐日悬浮详情卡）、多序列折线/面积趋势图（输入/输出/缓存命中/缓存创建/成本，双轴，7/30 天切换）、模型用量环形图
费用估算——按模型配置价格（每 1M tokens 的输入/输出/缓存读/缓存写）；内置 DeepSeek 刊例价；未配置价格的模型不计费而不是瞎猜
每日超限守卫——可选每日 token / 费用上限；warn 模式全局横幅提醒，block 模式在请求发出前直接拦截
中英双语，跟随 DSH 主题令牌（--dsw-alias-*）；图标自带（宿主改图标名不会把面板弄成白屏），零外部运行时依赖

安装

桌面端（profile 名为 desktop）——用应用自带的 CLI：

dsh plugin --profile desktop add <本地绝对路径 / npm 包名 / GitHub 地址>

dsh 默认不在 PATH 上（桌面安装包不会加），可以直接调应用自带的启动器，或在应用设置里打开命令行：

"<安装目录>\resources\runtime\cli\bin\dsh.cmd" plugin --profile desktop add <规格>

装完完全退出 DeepSeek Harness 桌面端再启动（插件的宿主半边只在启动时加载），然后打开 设置 → 使用统计。命令会把 add 之后的内容原样转给 pnpm，本地路径、npm 包名、GitHub 地址都可以；bundle 层（dsh.profile.bundles）会自动补上。从 GitHub 地址安装时，客户端产物由 prepare 脚本现场构建，pnpm 可能要求先在 allowBuilds 里授权；npm 包则无需构建。

web profile（dsh web）：

dsh plugin --profile web add dsh-usage-guard   # npm
dsh plugin --profile web add <github 地址>      # 或从 GitHub

重启 dsh web，打开 设置 → 使用统计。

升级说明

统计数据存在 $DSH_HOME/usage-stats.json。除了价格与守卫设置，里面的内容都由会话日志推导，升级到 0.1.1 后首次启动会整表重折一次：被替换掉的那些日桶大约只记了真实用量的 1/8（旧版本的水位已经推到了每个日志末尾，增量续跑永远补不回来，实测本机 ×8.07）。首次启动后总量会跳到真实值；日志已被删除的会话，其历史用量会随之消失（聚合桶追不回来源）。

兼容性

DSH	会话日志	说明
0.2.x（已核对桌面端 0.2.0-rc.2）	`session.v4.jsonl.zstd`	当前适配目标；图标由插件自带，因为宿主的 `IconXxx16` 已改名为 `IconXxxOutlineRegular/Medium`
0.1.x	`session.jsonl.zstd`	宿主半边不变；客户端面板在 `Button` / `Input` 仍存在时继续可用

开发

pnpm install
pnpm build          # tsdown + wrap-client → dist/client.js（宿主加载 host/，浏览器加载 dist/）
pnpm test           # vitest：宿主 fold/日志/路由/存储/迁移/守卫/入口装配 + 客户端渲染
pnpm verify:bundle  # 按浏览器的方式加载 dist/client.js 并校验注册行为
pnpm verify:parity  # 用本机真实会话日志与 dsh-token-meter 投影的逐行转写对拍
pnpm check          # test + build + verify:bundle

pnpm test 里还有真实数据的冒烟测试：client/render.smoke.test.tsx 会用 $DSH_HOME/usage-stats.json（缺省 ~/.dsh）渲染全部图表，本机没有该文件时退回合成数据。
