Preface¶

The dsh web profile of DSH is suitable for using DeepSeek V4 Flash/Pro for long-running tasks. Peak/off-peak API pricing results in different per-token rates during peak and off-peak hours, and sending during peak hours directly impacts costs. OffPeak is a DSH plugin: it provides peak/off-peak price reminders before you send, and allows you to schedule commands for execution during low-price periods.

What This Is¶

OffPeak is maintained by christophersmith2737-commits, with the npm package name dsh-offpeak, licensed under MIT. It is intended exclusively for the web profile (dsh web), addressing the choice between “sending immediately during peak hours” and “executing at a low price.”

Core Features¶

The plugin intervenes when all of the following conditions are met:

• The current model is DeepSeek V4 Flash / Pro.
• The current time falls within Beijing peak hours: 09:00–12:00 or 14:00–18:00.
• You press Enter or click Send in the composer.

After triggering:

• The message remains in the input box.
• A popup displays the peak/off-peak price card per million tokens for the current model.
• You can select Continue to send immediately.
• You can select Schedule for scheduled execution.
• You can select Don't remind me today, and no further popups will appear until the next Beijing midnight.
• The popup can be closed, and the draft is preserved.

Schedule provides a time wheel:

• Only off-peak hours are selectable: 0–8, 18–23.
• Past times are removed.
• Minutes range from 00–59.
• After 23:00, the wheel rolls over to the next day’s 0–8.
• When the scheduled time arrives, a local server submits the command to the original session, with no need for the browser to be open at that moment.

Other behaviors:

• Running commands are not interrupted by popups; reminders appear for the next command during peak hours.
• Enter during IME composition is not intercepted.
• Non-intercepted paths trigger a non-blocking server-side fallback reminder.
• Peak/off-peak determination uses Asia/Shanghai wall-clock time, regardless of the machine’s timezone.
• Prices are hardcoded; no network calls, no telemetry.

Installation and Activation¶

The web profile is required by default. Installation command:

dsh plugin --profile web add dsh-offpeak

For manual installation:

1. Copy the package to the shared plugin directory.
   - Windows: %USERPROFILE%\.dsh\profiles\node_modules\dsh-offpeak
   - macOS / Linux: ~/.dsh/profiles/node_modules/dsh-offpeak
2. Append to $DSH_HOME/profiles/web/cordis.patch.yml:

- insert:
    - id: offpeak
      name: 'dsh-offpeak'
      config:
        effectiveFrom: '2026-08-17'
        debug: false

3. Restart dsh web.

The plugin remains dormant until effectiveFrom (2026-08-17); to enable it early or for testing, change this date to the current date, for example 2026-08-31.

Typical Usage¶

1. Enter a command during peak hours with DeepSeek V4 Flash/Pro, then press Enter or click Send.
2. In the price card, choose Continue, Schedule, Don't remind me today, or close it.
3. If you select Schedule, use the time wheel to pick 0–8 or 18–23 hours and 00–59 minutes.
4. At the scheduled time, the local server submits the command to the original session.

Applicable Scenarios and Notes¶

Suitable for:

• DeepSeek users of dsh web.
• Those who frequently run longer tasks with DeepSeek V4 Flash/Pro.
• Those who want to avoid sending during peak hours but still retain the option to send immediately.

Notes:

• Only the composer’s own send gestures are intercepted; subagent/queued messages are not.
• All writes accept only same-origin POST requests.
• State and tasks are persisted in $DSH_HOME/profiles/<profile>/offpeak.json.
• The plugin runs with the current dsh process permissions; inspect the source and license before installation.
• This document describes only the listed behaviors and does not substitute for a source code review.

Links¶

OffPeak has a specific role: it reminds you of peak/off-peak prices before sending and provides a local scheduling path to execute during low-price periods.
