dsh-cost-tracker · LLM Cost Tracking Plugin

   

English | 中文

A DeepSeek Harness Web (dsh --profile web) plugin that records daily LLM call costs and lets you inspect them per session, per model, and per day.


Features

• Automatically records usage for every model call: input (cache miss), cache hit, output, and reasoning tokens
• Estimates cost from a configurable pricing table (¥ / 1M tokens) with an optional peak-hour multiplier (default: Beijing time 9–12 and 14–18, 2×)
• Entry points:

- "¥ 花费统计" button at the sidebar footer (opens the dashboard) - "¥ 花费" button in the session header (shows that session's cost) - Per-session cost readout above the composer

• Dashboard tabs: Overview (today / 7 days / total), By Model, By Session, Recent Calls, Pricing
• Pricing can be edited in-app at any time; historical records are recalculated on save
• Zero token consumption: it only reads the usage data already returned by the model API and does local arithmetic — it never calls a model itself

Install

Option 1: npm (recommended)

dsh plugin --profile web add dsh-cost-tracker

Then restart dsh web and refresh the page — the "¥ 花费统计" entry appears at the bottom of the sidebar.

> If you use the npmmirror registry in China, note that newly published packages take a few minutes to hours to sync. If install reports 404, point pnpm at the official registry temporarily: > dsh plugin --profile web add dsh-cost-tracker --registry=https://registry.npmjs.org/

Option 2: install from GitHub

dsh plugin --profile web add github:lyfZhixing/dsh-cost-tracker

(No build step — nothing extra to configure.)

Option 3: local directory (development / internal sharing)

dsh plugin --profile web add /path/to/dsh-cost-tracker

Uninstall

dsh plugin --profile web remove dsh-cost-tracker

Uninstalling removes only the plugin; your local data file ~/.dsh/cost-tracker.json is kept.

Usage

1. Use any session as usual — every model reply is recorded automatically 2. Click "¥ 花费统计" at the sidebar footer to open the dashboard: - Overview: today / last-7-days / total cost, a 30-day daily bar chart, top models and sessions - By Model: calls, tokens, cost, and share for each model - By Session: cost and last-call time for each session - Recent Calls: the latest 200 call details - Pricing: edit peak hours, the default price, and per-model prices; one click adds any unpriced model that appears in your records 3. Close the panel with the ✕ button, clicking the backdrop, pressing Esc, or toggling the sidebar button

Pricing


• Unit: ¥ / 1M tokens; inputMiss = uncached input price, inputHit = cache-hit input price, output = output price
• Default prices (deepseek-v4-pro / deepseek-v4-flash) are estimates — adjust them in the Pricing tab to match your real billing
• The peak-hour multiplier applies to both input and output; timezone offset defaults to +8 (Beijing time)

Data & Privacy

• All data stays on your machine: ~/.dsh/cost-tracker.json (records, session titles, pricing table)
• No API keys or credentials: the plugin only reads usage data included in model responses and never calls any model API itself
• No network reporting; the page pulls stats from a local HTTP endpoint (/cost-tracker/data) every 4 seconds
• Cost calculation consumes zero extra tokens

FAQ

Q: No records / shows 0 after install? A: The plugin only records calls made after it is installed; past calls cannot be recovered. Also check the Pricing tab — unpriced models are flagged and fall back to the default price.

Q: The numbers don't match my bill? A: Default prices are estimates. Edit them in the Pricing tab (unit: ¥ / 1M tokens) to match your actual billing.

Q: Will uninstalling lose my data? A: No. The data file ~/.dsh/cost-tracker.json is independent; reinstalling the plugin restores it automatically.

Q: Install fails with 404 on the npmmirror registry? A: The mirror lags on new packages. Install with --registry=https://registry.npmjs.org/ temporarily, or retry later.

• lib/client.js is served live by the server (cache-control: no-cache) — edits take effect after a page refresh
• lib/index.js is host-side code — changes require restarting dsh web
• No TypeScript / no bundling / no external runtime dependencies; the client must be written in the window.__ModuleLoader__.load({ id, factory }) format

Changelog

• v1.0.1 (2026-08-17): added English README (README.en.md) and UI screenshots; documentation polish.
• v1.0.0 (2026-08-17): first public release. Automatically records usage per model call and estimates cost from a configurable pricing table; dashboard with Overview / By Model / By Session / Recent Calls / Pricing; peak-hour multiplier and custom pricing support.
