dsh-ui-billing

When you juggle multiple conversations in the DeepSeek Harness Web GUI, two numbers tend to stay out of sight: how much this session costs and what balance is left on the account. dsh-ui-billing pins a compact billing panel to the sidebar foot so both figures are one glance away — no page switch, no API docs.

The session-cost side folds every assistant and message usage record through the billing session projection against a built-in V4 CNY price table (including Beijing weekday peak windows). Switching conversations swaps the number instantly; paging and compaction never alter it. Models without a price entry are annotated as (+N tokens unpriced) rather than silently treated as free. The balance side reads the provider account over the /billing connection channel, auto-refreshes every 60 seconds while mounted, and offers an on-demand refresh button. When the sidebar collapses, the widget shrinks to a single ¥ glyph whose tooltip carries both lines and whose click triggers a balance refresh. The whole plugin is display-only: it produces no model-visible input, writes nothing to the session log, and emits no new RPC calls. Credentials never enter the browser bundle.

If you run multiple conversations in the Harness Web GUI daily and want token spend at a glance, or you manage a DeepSeek account balance, this plugin installs cleanly into the web profile with no source edits to the harness checkout.
