dsh-plugin-offpeak-badge

DeepSeek API peak / off-peak billing badge for the DeepSeek Harness (DSH) Web GUI — as a plugin, in 中文 and English.

A pill in the top-left brand row tells you, at a glance, whether the DeepSeek API is charging you the off-peak rate (half price) or the peak rate right now. Hover it for the rule, today's day type and the exact moment of the next switch.

🐳 deepseek HARNESS  [Idle] / 〔空闲〕   ← green = off-peak (half price)
🐳 deepseek HARNESS  [Peak] / 〔高峰〕   ← amber = peak

Collapse the sidebar and the badge becomes a dot on the collapse button, so it stays visible in rail mode.

What it shows

Install

Requires a DSH installation (dsh --version) and Node ≥ 18. The package is a DSH bundle — it declares dsh.bundle.patch and ships a cordis.patch.yml — which is what makes the one-line install work:

# straight from GitHub (pnpm fetches the sources; this package needs no build step,
# so there is no install-script approval to grant)
dsh plugin --profile web add github:AK-blank/dsh-plugin-offpeak-badge

# …or from a local clone
git clone https://github.com/AK-blank/dsh-plugin-offpeak-badge.git
dsh plugin --profile web add ./dsh-plugin-offpeak-badge

The same thing from the GUI: Plugins → Add plugin, paste the repository URL — the dialog section below lists every accepted input.

dsh plugin installs the dependency and appends the bundle to the profile's dsh.profile.bundles; the running dsh web reloads the configuration live — no restart. If the badge does not show up, reload the browser page once.

git clone https://github.com/AK-blank/dsh-plugin-offpeak-badge.git
cd dsh-plugin-offpeak-badge
node install.mjs

Install from the GUI (no terminal)

Open Plugins in the sidebar, click Add plugin, paste a spec and press Install.

The dialog parses the spec exactly like dsh plugin add, so these all work:

Two things that trip people up:

• A bare owner/repo is rejected. The git shorthand needs its github: prefix, and the npm package-name rule forbids the uppercase owner, so the dialog reports an invalid spec before it tries anything. Write github:AK-blank/dsh-plugin-offpeak-badge or the full URL.
• The install-source (mirror) selector only affects npm installs, not GitHub ones.

If the plugin is already installed, adding the same spec reports already installed — remove it first.

Manage it from the same page

The plugin then appears under Installed, with a toggle for the bundle and one for the row it declares; Uninstall asks for confirmation and removes it. DSH does not auto-update plugins yet, so upgrading means uninstalling and installing the new version. The equivalent CLI verbs:

dsh plugin --profile web list                              # pnpm's view of profile packages
dsh plugin --profile web remove dsh-plugin-offpeak-badge

Uninstall

dsh plugin --profile web remove dsh-plugin-offpeak-badge   # bundle install
node install.mjs --uninstall [--purge]                    # script install

Why it is (or is not) listed in the GUI's Plugins page

That page is an inventory of packages: the profile's selected bundles, the profile's dependencies, and the optional bundles the DSH installation itself ships. dsh plugin add puts this plugin in all the right places, so it appears under Installed with an enable/disable toggle.

A row written by hand into the profile's cordis.patch.yml — what install.mjs does — is a real loader row (the badge works exactly the same), but it belongs to no package, so that inventory has nothing to list. To get the page entry after a script install, switch to the bundle install and drop the hand-written row:

dsh plugin --profile web add /path/to/dsh-plugin-offpeak-badge
# then delete the entry install.mjs appended to the profile's cordis.patch.yml

How the billing rule is decided

The plugin implements the footnote on DeepSeek's official pricing page, verbatim:

空闲时段价格为高峰时段价格的一半。北京时间周一至周五（不含中国法定节假日）9:00 - 12:00、14:00 - 18:00 为高峰时段；其余时段，包括周末及中国法定节假日全天均为空闲时段。

Off-peak rates are half of the peak rates. Peak hours are 01:00 - 04:00 and 06:00 - 10:00 UTC, Monday through Friday, excluding Chinese public holidays. All other hours are off-peak, including weekends and Chinese public holidays in full.

The two windows are identical (UTC + 8 h = Beijing); day classification is always the Beijing calendar day:

peak  ⇔  Beijing date is Mon–Fri  ∧  not a statutory holiday  ∧  time ∈ [09:00,12:00) ∪ [14:00,18:00)
idle  ⇔  every other instant

Two details people ask about:

• Adjusted ("调休") weekends. A weekend that holiday adjustment turns into a working day is still a weekend, and weekends are off-peak in full — so it stays off-peak all day. Chinese media summarised this as "调休上班的周末、中国法定节假日全天均按空闲时段计费"; that sentence is a news headline rather than official wording, but the conclusion is correct and needs no extra rule. The tooltip still names such a day, so the calendar never looks wrong.
• Holidays that fall on a weekday never enter peak hours ("excluding Chinese public holidays"). The plugin ships the statutory holiday list, so it knows the difference between a holiday Monday and an ordinary Monday.

Calendar coverage

For a year whose notice is not published yet (2027 at the time of writing) the rule degrades to "Monday–Friday are peak-eligible" and the tooltip says "the 2027 holiday notice is not published yet; Monday to Friday is assumed" instead of pretending to know. Adding a year means appending one entry to CALENDAR in lib/client.js; the self-test then checks its day count, duplicate-free dates, that make-up days fall on a weekend, and that an official source URL is recorded.

Language

The plugin ships both dictionaries in one registration call (ctx.locale.register(NS, { zh, en })), which is what the DSH locale service requires, and every seat is registered with that namespace so the framework re-renders on a language switch:

• the pill follows the GUI language: 空闲/高峰 in Chinese, Idle/Peak in English;
• the tooltip, the countdown wording, weekday names and the screen-reader announcement are translated too;
• the rule line quotes the official English wording on the English page and the official Chinese wording on the Chinese one;
• node selftest.mjs fails if the two dictionaries ever drift: it asserts identical key sets, identical {placeholder} sets per key, no blank values, and renders the tooltip in both languages.

Verify

node selftest.mjs          # 89 offline assertions, no network, no browser
node selftest.mjs --now    # …and print the current verdict in both languages

The self-test loads lib/client.js the same way the browser module table does (stub window.__ModuleLoader__, stub require), then covers the module contract, all ten window boundaries of a working day, weekends and make-up work weekends, eight statutory holidays that fall on weekdays, the calendar-uncovered degradation, the next-switch computation (same day, across a weekend, across a holiday), calendar integrity, timezone independence (the verdict is identical under TZ=UTC and TZ=America/New_York), both dictionaries, and the registration contract through a stub context.

How it plugs into DSH

This is a dual-face Cordis plugin, exactly like the official @deepseek-ai/dsh-client-ui-* packages:

lib/client.js deliberately avoids a build step: it is the same pre-bundled CJS-factory form the official client plugins ship in, so the repository can be read, diffed and published as-is. It requires only platform seed words (react, @deepseek-ai/dsh-client-ui-primitives) plus the slots and locale services.

Design notes

• Why the brand seat is taken at priority: -1. sidebar.brand.name is a single slot: same-priority registrations throw, and only the lowest-priority registration renders. The official brand plugin sits at 0, so a lower priority is the only way to add anything next to the wordmark. This plugin re-renders the official BrandWordmark itself, so the branding is unchanged — only the pill is new.
• Why the wordmark is 22 px tall instead of 24. At the default 280 px sidebar the brand row is a fixed budget (24 icon + 8 + wordmark + 6 + pill ≤ 216 px). Trimming the wordmark by 2 px is what lets a two-character pill fit without clipping. Below a 250 px row the pill degrades to a dot automatically (measured with a ResizeObserver).
• Why the rail dot lives in shell.overlay instead of sidebar.toggle.badge: that single slot is held by the official settings plugin's DesktopUpdateBadge, which also reports a dropped/reconnecting host connection. Taking the slot would swallow those signals, so the dot is drawn additively into the overlay layer, positioned from the collapse button's viewport rectangle.
• Click-through is blocked. The whole brand row is the "new session" button; the badge stops click / mousedown / pointerdown, so clicking it never starts a session.
• corner-shape: round is set explicitly on the dots: DSH's global design language renders border-radius as a superellipse (squircle), which would turn a dot into a rounded square.

Compatibility

• Built and verified against DSH 0.2.0-rc.2 (client plugin API dsh.client + __ModuleLoader__, slot registry, locale registry) — recorded in dsh.compatibility.dshReleases.
• Official packages are declared as peerDependencies with prerelease-carrying ranges (>=0.2.0-rc.1 <1.0.0-0), so -rc harness builds resolve instead of being silently excluded. Nothing is imported from them at runtime except the shell-provided seed @deepseek-ai/dsh-client-ui-primitives.
• No runtime dependencies, no build step, no network calls: the badge is computed locally from the clock and the bundled calendar. The git install therefore needs no pnpm allowBuilds approval.

Community

• Topics on this repo: dsh-plugin dsh dsh-plugins deepseek-harness deepseek-harness-plugin cordis cordis-plugin i18n. DSH's own README asks plugin authors to add the dsh-plugin topic for discoverability, which is also how dsh-plugin-radar indexes plugins.
• Community catalogs this plugin is submitted to / listed in: awesome-dsh-plugin (the source behind awesome-dsh-plugin.com and dsh-market) — the ready-to-PR entry lives in contrib/AK-blank__dsh-plugin-offpeak-badge.yml. To submit it: fork the list, copy that file to data/plugins/AK-blank__dsh-plugin-offpeak-badge.yml and open a PR — the list's CI requires the repository to be at least one day old, and the dsh-plugin topic (which this repo already carries) is what makes dsh-plugin-radar pick it up automatically in the meantime.
