What it adds to DSH
Shows the current peak/off-peak tier, countdown to the next tier, session token details, and estimated API cost beside the chat input.
Mechanism evidence ↗Before you choose it
dsh-tidewatch adds a floating card beside the DeepSeek Harness chat input. It identifies the current pricing tier, counts down to the next phase, and can expand to show Beijing-time windows, token usage, per-model cost details, and CNY/USD display selection.
Best for
DeepSeek Harness users who want a compact, in-session view of time-based pricing and token spending.
Common tasks
- Check whether the current time falls in a peak or off-peak pricing window.
- See a running estimated cost and token breakdown for the current chat session.
- Expand the card to compare model-level spending or switch between CNY and USD.
Permissions and data
The supplied documentation describes processing model-call usage events into a session cost projection and retaining the selected display currency.
Permissions- Uses the DeepSeek Harness web client surface.
- Reads model-call usage information available to the Harness session.
- Calculates and stores a session cost ledger in USD for display.
- Remembers the user's selected CNY or USD display preference.
- No additional credentials are declared in the supplied evidence.
Limitations
- Costs depend on bundled pricing constants and are not a live official pricing feed.
- The CNY display uses a fixed 6.67 exchange rate.
- Pricing updates require manual changes to both calculation and display constants.
- Peak/off-peak determination uses UTC while the schedule is displayed in Beijing time.
What DSHub checked
- The immutable source commit and bundle structure were verified.
- The manifest declares a web client, a costUsage projection, Node.js >=20, and DeepSeek Harness >=0.1.0-rc.5.
- The source documents a floating peak/off-peak cost card and session token details.
What DSHub did not check
- Installation was not executed.
- Runtime behavior, cost accuracy, and compatibility with a specific Harness installation were not independently verified.
- The npm registry distribution was not found.

DeepSeek 峰谷时刻悬浮徽章：一张悬浮在输入框旁的潮汐卡，告诉你此刻是峰期还是谷期、距下一阶段还有多久、本次会话花了多少钱。
- 状态点：峰期橙红 / 谷期蓝绿，一眼可辨
- 折叠态：
● 峰期 距谷期 03:33 · ¥0.12 - 展开态（点击展开）：官方峰谷时段表（北京时间）、当前档位价格、本次会话 Token 明细、汇率设置
- 计费：官方峰谷两档价格（美元口径），按每次调用实际发生时刻的档位计价，缓存命中/未命中分开
- 币种：默认人民币显示（固定汇率 6.67，与官方人民币标价一致），展开面板可一键切换美元（4 位小数）
- 跟随 GUI 亮/暗主题（
--dsw-*变量）
峰谷时段（官方依据）
DeepSeek 官方自 2026-08-17 起实施峰谷分时定价：
| 时段（UTC） | 北京时间 | 档位 |
|---|---|---|
| 01:00 – 04:00 | 09:00 – 12:00 | 峰 |
| 04:00 – 06:00 | 12:00 – 14:00 | 谷 |
| 06:00 – 10:00 | 14:00 – 18:00 | 峰 |
| 10:00 – 次日 01:00 | 18:00 – 次日 09:00 | 谷 |
谷期价格为峰期的一半。徽章按 UTC 窗口判定当前档位（官方口径），时段表展示按北京时间。
周末规则（2026-08-23 起）：周六/周日（UTC 自然日）全天按谷期计价，无峰谷切换；下一阶段切换点为下周一首次进入峰时。
计费口径
- 价格单位：美元 / 1M tokens（官方定价页口径），成本 = 输入未命中 × cacheMiss + 输出 × output + (缓存读 + 缓存写) × cacheHit；其中「输出」已含推理 token
- 峰谷时代之前（2026-08-16 16:00 UTC）的调用按当时的基础价计费（历史正确性）
- 每次调用的费用按事件发生时刻的档位计算，跨峰谷切换不漂移
- 账本金额以美元存储，显示时按固定汇率 6.67 换算人民币（默认）或直接显示美元
安装
需求：Node.js ≥ 20 + DeepSeek Harness（带
dsh plugin命令的版本）。
# npm 包安装（发布后可用）
dsh plugin --profile web add dsh-tidewatch
# 或本地目录（开发调试）
dsh plugin --profile web add link:./dsh-tidewatch
安装后重启 dsh web 生效。
使用
- 徽章悬浮在输入框右侧、与输入框垂直居中对齐；窄窗口放不下时自动移到输入框上方，不遮挡输入框与官方统计栏
- 点击徽章展开/收起详情面板：时段表、当前档位价格、Token 明细、币种切换（¥ / $）
- 点击「本次会话费用」行可展开分模型花费明细（各模型的 token 与花费分别列出，合计 = 分模型之和）
- 币种选择即时生效并记住；人民币 2 位小数，美元 4 位小数
