dsh-token-usage

简体中文 | English

A dsh usage plugin that displays model token usage right in the Web UI. After installation, open Settings (the gear icon in the sidebar) and you'll find the Token Usage page — summary cards (with cost), a daily total-token line chart, a per-model breakdown, and per-model pricing dialogs, all filterable by date range and model, exactly as shown in the screenshot above.

Repo: https://github.com/LaoYueHanNi/dsh-token-usage

Features

• Live hook: every successful model request is appended to per-day JSONL files (request id, model, input / output / cache-read / cache-write tokens, time, session id).
• Web stats page: filters (date range + model + 1d/7d/30d shortcuts), summary cards, daily trend chart (hover a day for its total), per-model table.
• Cost figures & model pricing: per-request cost is computed live from per-model rates (¥ per million tokens) — a highlighted total-cost card, a cost column in the per-model table, and a warning strip for unpriced models (their cost counts as ¥0). Every priced model's name carries a small rates button that opens a dialog with that model's full price table: each row is one billing condition (default rates, context tiers like ≥ 512K, peak windows like 09:00-12:00, grouped under time rules' date windows), with the in/out/cache/write rates as aligned columns — mirroring exactly what the per-record resolver bills. Rates merge from two files: every startup mirrors the cloud model-price-table feed (the same source cc-switch-analyzer pulls) automatically, and pricing.json holds manual overrides.
• History backfill: the first startup syncs requests that happened before installation (idempotent).

Model pricing

Every record is priced individually: each one resolves through the analyzer's rule chain at its own timestamp — the covering time rule first (its context tiers, its peak slots), else the model root's tiers → peak slots → base rates. Tier matching approximates the context size by the request's input-side tokens (input + cacheRead + cacheWrite). A price update re-prices the whole history instantly, with no data rebuild. Rates come from two files merged on read — pricing.json entries always win (a manual entry replaces that model's cloud rules wholesale):

File	Source	Notes
pricing.ccsa.json	startup auto-fetch	Verbatim mirror of the cloud model-price-table feed (the analyzer's source); refreshed on every dsh restart, falling back to the previous mirror on failure
pricing.json	hand-edited	Overrides synced rates or adds missing models; manual tweaks survive re-syncs

Cloud feed shape (currency must be RMB; both modelId and every alias become matchable keys; timeRules / contextTiers / dailySlots all take part in billing):

{
  "version": 4,
  "updatedAt": 0,
  "currency": "RMB",
  "models": [
    { "modelId": "deepseek-chat", "inputCostPerMillion": 2, "outputCostPerMillion": 8,
      "cacheReadCostPerMillion": 0.5, "cacheCreationCostPerMillion": 1, "aliases": ["deepseek-v3"] }
  ]
}

Flat pricing.json shape (keys are model ids matching the recorded model exactly; inputPerMillion and outputPerMillion required, cacheReadPerMillion / cacheWritePerMillion optional and falling back to the input rate):

{
  "deepseek-chat": { "inputPerMillion": 2, "outputPerMillion": 8, "cacheReadPerMillion": 0.5 }
}

A broken file or invalid entries leave the affected models unpriced without breaking the stats page; save and refresh the page to apply changes. Default location: ~/.dsh/token-usage/ (wherever path points when configured).

Install

From GitHub (recommended)

dsh plugin --profile web add github:LaoYueHanNi/dsh-token-usage

The package declares dsh.bundle, so add wires the plugin into the profile's layer stack automatically — no config editing needed. The built lib/ ships in the repo (there is no prepare script), so git installs work out of the box without any build allowlist. The first startup runs one history backfill, afterwards it records in real time.

From a local directory (development)

dsh plugin --profile web add link:D:/plugins/dsh-token-usage

link: installs a symlink: rebuild the plugin and restart dsh web to apply changes.

Update

dsh plugin --profile web update dsh-token-usage

Remove

dsh plugin --profile web remove dsh-token-usage

The plugin is removed from the profile and stops loading. Data files under $DSH_HOME/token-usage/ are kept — delete them manually if you no longer need them.

Development

Build the plugin once:

npm install
npm run build && npm run build:client

No prepare script — by design. The compiled lib/ output is committed to the repo. pnpm ≥ 10 refuses to run build scripts of git-hosted dependencies unless they are allowlisted (ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED), so a prepare script would break the zero-config github: install for every user. Shipping prebuilt output instead keeps dsh plugin add github:LaoYueHanNi/dsh-token-usage working out of the box. After changing anything under src/, always rebuild and commit the updated lib/, or installs will get stale output:

npm run build && npm run build:client
git add lib/

Temporary mount — effective for this launch only, no profile changes. cordis.yml points at the built lib/index.js:

dsh web --patch <plugin-dir>/cordis.yml

This mode only mounts the host half (data recording keeps working); the stats page needs the client bundle resolved by package name, so for UI development use the link: install above instead: run npm run build && npm run build:client (or npx tsdown --watch in the plugin directory), restart dsh web, and the browser plugin hot-reloads automatically.
