dsh-token-cost

dsh-token-cost

A DSH plugin that shows per-project LLM token usage and converts tokens to RMB cost, split into:

• 输入（未命中） — uncached input tokens
• 命中 — cache-hit input tokens (cacheReadTokens)
• 输出 — output tokens

Costs are calculated from the model's standard price table (CNY per 1M tokens). Unknown models are listed with their token counts but no cost, so you can add/override prices without touching code.

Features

• Reads local DSH session logs (~/.dsh/sessions or $DSH_HOME/sessions).
• Aggregates by project (the session cwd) and by model.
• Adds a 💰 button to the DSH web sidebar footer; the panel shows project totals and expandable model-level breakdown.
• Zero runtime npm dependencies: uses Node's built-in node:zlib Zstandard decoder.
• Loopback-only HTTP API (/dsh-token-cost/*).

Install

Install the subdirectory dsh-token-cost, not the parent dsh plugin folder. The parent folder has no package.json, so installing it produces no sidebar button.

Use the absolute path (the path contains a space, so quote it):

dsh plugin --profile web add "file:/Users/dg/Documents/dsh plugin/dsh-token-cost"

Or, from inside this directory:

cd /Users/dg/Documents/dsh plugin/dsh-token-cost
dsh plugin --profile web add "file:$PWD"

If you previously installed the wrong folder, remove it first:

dsh plugin --profile web remove "dsh plugin"
dsh plugin --profile web add "file:/Users/dg/Documents/dsh plugin/dsh-token-cost"

Then restart dsh web and refresh the browser. A 💰 button appears at the bottom of the sidebar.

You can also use the included installer script:

./scripts/install.sh

How it works

The host plugin scans every session.jsonl.zstd / session.jsonl under the DSH sessions directory. It replays:

• session.cwd → project
• request/header → current model
• assistant/chunk { type: 'usage' } and assistant/message.usage → input / cache-hit / output tokens

The same (turn, step) usage sample is de-duplicated (a later assistant/message replaces the earlier usage chunk), matching DSH's own token-meter accounting.

Price table

Built-in DeepSeek official RMB prices (元 / 1M tokens):

You can override prices in the profile's cordis.patch.yml (a patch row replaces the whole config, so include every price you want to keep):

- id: token-cost
  config:
    prices:
      deepseek-chat:
        input: 2
        hit: 0.5
        output: 8
      deepseek-reasoner:
        input: 4
        hit: 1
        output: 16
      deepseek-v4-flash:
        input: 2
        hit: 0.5
        output: 8
      deepseek-v4-pro:
        input: 4
        hit: 1
        output: 16
