dsh-peak

A live peak/off-peak pricing indicator for the DeepSeek Harness, shipped as an installable dual-face bundle.

DeepSeek's API moved to peak/off-peak pricing on 2026-08-16 16:00 UTC: during peak windows the rate is 2× the off-peak rate, and the windows line up almost exactly with Chinese work hours. This plugin makes that visible:

• Composer pill (browser): a small always-visible control at the left of the input row — red "PEAK" during peak windows, green "OFF-PEAK" otherwise, with a live countdown to the next switch and a hover tooltip showing UTC + Beijing times.
• dsh_peak_status tool (host): the agent can call it before suggesting or running long/expensive work, so it can warn you when you're about to pay the peak rate.

Pricing windows

Window	UTC	Beijing
Peak 1	01:00–04:00	09:00–12:00
Peak 2	06:00–10:00	14:00–18:00
Off-peak	everything else	— (half of peak)

Requirements

• A DeepSeek Harness web profile (the pill mounts in the browser; the tool registers host-side)
• No runtime dependencies — the host half uses a raw ctx.tools.register definition and the client bundle's only external is react

Install

dsh plugin --profile web add dsh-peak            # once published to npm
dsh plugin --profile web add github:geokkjer/dsh-peak   # or straight from this repo

Or from a local checkout of this repo:

cd /path/to/dsh-peak
dsh plugin --profile web add .

dsh plugin runs pnpm add in the profile directory and registers the package as a bundle layer (dsh.bundle.patch → cordis.patch.yml). After the next dsh web restart, both halves activate: the host row registers dsh_peak_status, and the dsh.client declaration makes the browser roster serve /plugins/dsh-peak/client.js, mounting the pill in every session.

Usage

Ask the agent:

• "is it peak pricing right now?" → calls dsh_peak_status
• "run this long job off-peak" → the agent checks dsh_peak_status first and reports the window

The pill itself needs no interaction: it self-updates every 30s and flips color at each window boundary.

Development

The repo is deliberately build-free: index.js (host tool) and client.js (browser bundle in the module-loader format) are committed plain ESM, so pnpm add works with no prepare step.

npm test

Runs the smoke suite: host identity + tool registration, window classification at known instants (09:46 UTC → peak, next switch 10:00; 05:00 UTC → off-peak), and client bundle materialization against a stubbed module loader + React.
