dsh-token-anxiety

English | 中文

The Token Anxiety widget tracks the cost of every task in your conversation in real time. It runs in the band under the chat composer and shows DeepSeek pricing status (peak/valley), per-task token usage and cost, and a one-click analysis of where tokens were spent. It is installed as a bundle with no additional dependencies.

Install (from any directory; the path is absolute):

# from npm (published package)
dsh plugin --profile web add dsh-token-anxiety

# or from a local checkout
dsh plugin --profile web add /path/to/dsh-token-anxiety

Then restart dsh web and refresh the page — done.

• Live pricing status — peak/valley windows for your timezone, plus local time
• Cost overview — current cost and the projected post-hike figure in red
• Per-task breakdown — a sortable table of every task with its total cost and token usage; hover any row for details
• Currency support — COP / USD / CNY by default, plus ~40 more with regional formatting (¥, €, £, ₩…) and live FX rates
• One-click explain — a short, streamed analysis of why a task cost what it did, written in your language
• Dark & light, English & Chinese — follows your harness theme and locale

It is packaged as an installable bundle for DeepSeek Harness (composed through your profile, so it survives restarts).

Requirements

• DeepSeek Harness with a web profile (dsh web) — the bundle is composed through the profile's dsh.profile.bundles list.
• Node.js 22+ (the harness's own runtime; the bundle itself adds zero dependencies — node builtins only).

Usage

• Hover or click the widget in the composer band to open the popup.

• Overview — headline cost in a big hero number (current, plus the projected post-hike figure in red when Projected is on), tasks / requests / tokens, and the pricing table: current vs projected rates per model, with the projected peak/valley values colored green when cheaper than the current rate and red when more expensive.

• Tasks — a sortable per-task table (# or share %). Each row shows its total cost; with Projected on, the cost column adds the projected peak/valley split on two rows. Hover a row for a details tooltip; click a bar to select the task and run Explain.

  

• Currency — pick any enabled currency (defaults COP / USD / CNY); open the chooser to see FX rates, add more (flags + search), or remove them.

• Explain — one small LLM call per task; the analysis streams in as it is generated and is written in the conversation's language (a tiny LLM call detects the ISO 639-1 code of the task's user prompt). The result is a compact ~60-100 word report in four labeled lines — Wanted: / Happened: / Avoid: / Next time: — rendered as rich text with bold accent labels.

Security

See SECURITY.md for the full review. Summary: the three HTTP routes are POST-only, cap request bodies, validate all input, and apply the same browser-trust fence as the harness /api prefix (loopback/trustedHosts Host, same-origin Origin, sec-fetch-site); the explain route has an anti-abuse throttle and hard timeouts so a stalled model can never wedge it; nothing is written to the session log; zero runtime dependencies.

How it works

• cordis.patch.yml inserts one plugin row (token-anxiety) into the profile.
• The node half (index.js) registers the tokenAnxiety session projection: a pure fold over the ROOT session log that accumulates per-turn token usage, cost, tool signals and waste flags. No network, no model calls.
• The same node half registers POST /token-anxiety/explain on the harness webserver (ctx.webServer): the widget's Explain button fetch()es it and the handler runs the LLM analysis. The response streams back as NDJSON ({"delta": …} lines) so the widget renders the answer as it is generated; a 60s host timeout aborts stalled LLM streams (the client aborts at 70s and shows a visible error). The language is detected with one tiny LLM call returning an ISO 639-1 code. Nothing is appended to the session log, so sessions stay loadable.
• POST /token-anxiety/pricing-sync (same trust fence) fetches the official DeepSeek pricing page, turns it into readable text, and sends it with a strict JSON schema to an LLM call — no layout scraping in code. The model returns CNY-per-1M prices (current, peak, valley), the Beijing peak windows and the effective date; the host validates, converts CNY→USD at a fixed 7.0 rate, and writes pricing.override.json next to the bundle with an explicit schema/currency/unit shape. A restart loads the override over the embedded defaults (the model list derives from the active pricing, so new models surface automatically), and the pricing-derived stateVersion discards stale projection caches.
• The browser half (lib/client.js) is a hand-written client bundle registered through window.__ModuleLoader__.load({ id, factory }) — no bundler, no minification. It reads the projection with useProjection('tokenAnxiety') and computes peak/valley status, local time and the hour strip in the browser from the projection's embedded pricing config.

Install

From npm (published package)

The package is published to the public npm registry:

npm view dsh-token-anxiety          # verify: name, version 0.1.x, MIT

Install it into a harness profile (this adds it to the profile's package.json dependencies and its dsh.profile.bundles list):

dsh plugin --profile web add dsh-token-anxiety

Or install the package directly in any npm project:

npm install dsh-token-anxiety
# or pin the exact version:
npm install dsh-token-anxiety@0.1.0

Note: for dsh web to load the widget, the profile must depend on the package and list it in dsh.profile.bundles — dsh plugin --profile web add dsh-token-anxiety does both automatically.

From a local checkout

# from any directory; the path is absolute
dsh plugin --profile web add /path/to/dsh-token-anxiety

After either install

Restart the web server (dsh web / however you launch it). A restart is required because the bundle row and the client boot graph are composed at boot.

Update after editing

The bundle is pnpm-linked into the profile, so editing files here is enough for a HOST-half change; the client graph only picks up a changed bundle after a restart. After changing files, restart the web server. To remove:

dsh plugin --profile web remove dsh-token-anxiety

Configuration

Currencies

Defaults are COP / USD / CNY. Add or remove currencies from the chooser (any code in the ~40-currency catalog); the enabled list persists to pricing.override.json via POST /token-anxiety/currencies (a restart loads it). Rates are USD-base, refreshed by the pricing sync and cached for 24 h.

Pricing

Prices are embedded in PRICING (index.js) as the fallback and can be refreshed from the official DeepSeek pricing page:

curl -X POST http://127.0.0.1:3080/token-anxiety/pricing-sync -H "Content-Type: application/json" -d '{}'

The route fetches the page, asks a model to extract the current and peak/valley rates (CNY → USD at a fixed 7.0 rate; the Beijing peak windows and the effective date are parsed too) and writes pricing.override.json. FX rates (open.er-api.com, keyless) ride along, cached daily. A restart merges the override over the defaults; the pricing-derived stateVersion discards stale projection caches.

Language

When the harness locale is zh, the whole UI renders in Chinese and the currency defaults to CNY. It follows the harness locale.preference setting.

Known limitations

• Root-session tasks only. The projection fold is per-session and synchronous, so the subagent tree the old dynamic plugin aggregated on demand cannot be folded here. Subagent conversations do not appear in the widget. (The explain_task tool itself aggregates the full subagent tree, so its conversation context is complete.)
• Explain is a direct host route, not an agent turn. The widget's button fetch()es /token-anxiety/explain (registered by the host half on the harness webserver), and the host runs the analysis LLM call inline. The analysis lives in the widget's component state, so it does not survive a page reload and it is not part of the session log (deliberately: it never writes a custom session event, so sessions stay loadable). The explain_task tool is kept for conversational asks ("why did this cost so much?"). The route sits outside the harness /api prefix, so it applies the same browser-trust predicate itself (loopback or trustedHosts Host, same-origin Origin, sec-fetch-site); the deployment still binds loopback-only.
• Pricing is embedded and dated. The embedded PRICING is the fallback; refreshing it is a host-side action (POST /token-anxiety/pricing-sync, see Configuration) that writes pricing.override.json; a restart merges it over the defaults. Editing PRICING by hand still works; stateVersion derives from the active pricing, so any change discards persisted projection-cache rows.

pricing.override.json is runtime state (gitignored): it stores the synced pricing, FX rates and the enabled-currency list.
