dsh-peak-badge

A floating DeepSeek peak/off-peak pricing badge for the DeepSeek Harness (DSH) web GUI. It tells you at a glance whether DeepSeek tokens are currently billed at peak or off-peak rates — based on Beijing time, with zero configuration.

🟢 Off-peak hours — light green pill: 「优惠时段 · 半价」 (off-peak, half price) 🟠 Peak hours (09:00–12:00, 14:00–18:00 Beijing time) — light orange pill: 「高峰时段 · 单价×2」 (peak, 2× price)

Why

DeepSeek introduced peak/off-peak pricing (峰谷计费) on 2026-08-17: during the peak windows 09:00–12:00 and 14:00–18:00 (Beijing time), token prices are 2× the off-peak rate. This badge keeps that status visible at all times so you can decide whether to keep chatting or defer the expensive work.

Features

• Always current — refreshes every 30 s using Intl.DateTimeFormat('Asia/Shanghai') (no manual timezone setup).
• Draggable — move it anywhere; the position is remembered in localStorage and clamped to the viewport.
• Click for details — a card shows the current Beijing time, the peak/off-peak windows, and reference prices for DeepSeek V4-Flash / V4-Pro.
• Zero host risk — pure browser plugin; the host half is a no-op.
• Complements the text-rule reminder in AGENTS.md for agents working in basecamp-style repositories.

Install

dsh plugin --profile web add dsh-peak-badge

Restart dsh web, then hard-refresh the browser (Cmd+Shift+R on macOS / Ctrl+Shift+R elsewhere). The badge appears at the bottom-left by default — drag it wherever you like.

Usage

• See status: green = off-peak, orange = peak. The pill also shows the current Beijing time.
• Drag: press and hold, move, release. Position persists across refreshes.
• Details: click (without dragging) to open/close the info card.

Reference prices (effective 2026-08-17, CNY per million tokens)

Cache hits are billed at half the input price. Always check the official pricing page: https://api-docs.deepseek.com/quick_start/pricing

Structure

• lib/index.js — host half (no-op; browser-only plugin)
• lib/client.js — browser half: window.__ModuleLoader__.load() + shell.overlay slot
• cordis.patch.yml — bundle patch (inserts the peak-badge row)

Development

npm run check      # syntax-check host + client
dsh plugin --profile web add "link:$PWD"   # install from source

Uninstall

dsh plugin --profile web remove dsh-peak-badge
