a1113622001/dsh-session-stats-panel

A DeepSeek Harness (cordis) client plugin that shows a stats panel for the current session on the right side of the page:

Metric	Description
Average hit	Share of cache-hit input tokens (cacheReadTokens / billed input, accumulated across whole-round logs, 3-decimal precision)
Session cost	Accumulated cost estimated with DeepSeek official pricing (DeepSeek models only, see pricing below)
Remaining balance	DeepSeek account balance (read by the host route; the key stays server-side; refreshes every 2 minutes)
Runtime	Accumulated LLM + tool execution time
Requests	Number of closed model steps (steps, i.e. model request count)
Cumulative tokens	Input (miss) + cache-read + cache-write + output, shown with thousands separators (e.g. 3,251,237)

The panel registers in the framework's shell.overlay layer (a list slot — it stacks rather than replaces any existing UI), is pinned to the right edge of the page, and collapses to a small pill when you click the "–" in the title bar.

Data sources

• tokenUsage (token-meter projection) → cumulative tokens, average hit, cost;
• sessionStats (session-stats projection) → request count, runtime;
• The current model comes from the session models RPC (session.models, same source as the model picker — chat nodes carry no model field themselves);
• The remaining balance comes from the route /plugins/session-stats-panel/balance registered by this plugin's host half (the server resolves DEEPSEEK_API_KEY through the credentials service and calls the DeepSeek balance API; the key is never sent to the browser).

Pricing

Cost is estimated in the browser with a price table built into the plugin (CNY / million tokens, fetched from the DeepSeek official pricing page; cache writes are billed at the cache-hit price).

Official peak/off-peak pricing rules (peak windows are weekdays only, Beijing time 09:00–12:00 and 14:00–18:00; everything else — including all of Saturday and Sunday — is off-peak, priced at half the peak rate):

Model	Period	Cache-hit input	Cache-miss input	Output
deepseek-flash	off-peak	0.02	1	4
deepseek-flash	peak (weekday peak hours)	0.04	2	8
deepseek-v4-pro	off-peak	0.15	4.5	13.5
deepseek-v4-pro	peak (weekday peak hours)	0.30	9.0	27.0

CNY per million tokens; cache writes are billed at the cache-hit price.

deepseek-flash (DeepSeek-V4.1-Flash) and deepseek-v4-pro (DeepSeek-V4-Pro-0813) are the current official ids. The retired deepseek-v4-flash / deepseek-v4-flash-vision-exp ids are still callable — requests are served by DeepSeek-V4.1-Flash and billed at Flash prices — so they share the Flash row. Versioned ids (deepseek-v4-pro-0813, deepseek-v4-flash-0731) resolve to their family rather than the fallback, and any other deepseek-* model falls back to the Flash price.

The plugin auto-selects the price tier at "view time" (peak / off-peak; hover the cost row to see the tier). Session cost is an estimate: cumulative tokens cannot be sliced by time, so the whole amount is priced with whichever tier is active at view time.

Installation (web profile)

Via the bundle manifest (recommended)

dsh plugin add github:a1113622001/dsh-session-stats-panel

The plugin ships a cordis.patch.yml bundle patch, so the plugin add command installs it as an installable plugin that activates automatically (no manual loader row needed).

Manually from a local directory

1. Install the dependency (equivalent to dsh plugin --profile web add <this directory>):

   corepack pnpm --dir "$env:USERPROFILE\.dsh\profiles\web" add "C:\Users\baiyec\Desktop\Harness\plugins\dsh-session-stats-panel"
   

2. Append a loader row to $env:USERPROFILE\.dsh\profiles\web\cordis.patch.yml:

   - insert:
       - id: session-stats-panel
         name: 'dsh-session-stats-panel'
   

3. Restart the web service (dsh web). Afterwards, edits to lib/client.js are picked up by client-hot-reload (no browser refresh needed).

Project structure

• lib/index.js — host half (registers the /plugins/session-stats-panel/balance route that resolves DEEPSEEK_API_KEY server-side);
• lib/client.js — browser half (window.__ModuleLoader__ bundle format, registers the shell.overlay slot);
• lib/pricing.js — pure pricing/derivation/formatting logic, kept dependency-free so it can be unit-tested (mirrors the in-bundle constants in lib/client.js);
• cordis.patch.yml — bundle patch so dsh plugin add github:... installs and activates the plugin;
• package.json — declares dsh.client.platform: "web"; client-modules scans and serves /plugins/dsh-session-stats-panel/client.js.

Development

npm test        # run the pricing/derivation unit tests
node --check lib/*.js   # syntax-check every JS file
