dsh-peak-light

A tiny peak/off-peak pricing indicator for DeepSeek Harness: a 6px dot to the right of the sidebar brand (deepseek HARNESS).

Hover the dot to see the current period, the countdown to the next switch, and the billing rule. Clicking the dot does not bubble to the brand button, so it never opens a new session by accident.

Pricing rule (effective 2026-09-10 12:00 Beijing time)

Source: DeepSeek API pricing (checked 2026-10-23). The older "00:30–08:30 nightly discount" rule is retired.

Install

dsh plugin --profile <profile> add dsh-peak-light

Or install it from the Plugins page / DSH Market. This is a Web-client plugin: the host half is empty, and the browser half occupies the sidebar.brand.name slot with priority: -1 (single slots render the lowest priority), re-renders the official BrandWordmark, and appends the dot after the HARNESS badge.

If the official wordmark component is missing or the slot registration fails, the plugin steps aside and leaves the official brand untouched.

Development

npm run build     # inline src/policy.js + src/ui.js into lib/client.js
npm test          # policy unit tests + bundle smoke tests
npm run dev:install   # copy into the local DSH desktop profile (not for end users)

• src/policy.js — peak windows, 2026 holiday calendar, countdown (pure functions).
• src/ui.js — React component and slot registration.
• scripts/build-client.mjs — builds the self-contained CJS bundle.

Dynamic DSH bundles must register through window.__ModuleLoader__ (double underscore). The _ModuleLoader__ identifier used by built-in bundles is a local alias in the bootstrap scope; using it in a third-party bundle throws ReferenceError and makes DSH fall back to safe mode.

Known limits

• The holiday calendar currently ships 2026 only (weekday public holidays). Other years fall back to Monday–Friday and say so in the tooltip.
• Slot names are those of DSH 0.2.1-rc.2; a future slot rename needs a matching update in src/ui.js.
• Status indicator only: no notifications, no network calls, no credentials.
