dsh-ui-cost-meter

When you drive long multi-turn sessions through DeepSeek Harness, token spend scatters across pagination, retries, cache hits and model switches. After the fact, reconciling how much a session cost and where the tokens went means digging through logs and squaring them against a bill. dsh-ui-cost-meter drops a persistent cost pill right beside the composer so the running total is always in view without leaving the GUI.

The number is folded from the harness own durable provider usage log via the session projection seam, so paging and compaction cannot alter it and a page reload does not reset it. Clicking the pill opens a breakdown panel styled identically to the shipped stats pills, itemising each priced route, every cache bucket, and the tokens left unpriced because no rate matched. A missing rate never silently zeroes out: the amount carries a trailing plus sign and the panel names exactly how many tokens were skipped.

All rates live on the plugin row, expressed per million tokens, keyed by route with an optional global fallback, and the currency symbol is whatever you type in. The host half registers the cost projection; the browser half renders a React portal into the existing composer stats row so the pill inherits the shell CSS variables, spacing and radius without editing cordis.patch.yml.

Built for developers and teams who hop between DeepSeek V4.1 Flash, V4 Pro and other routes and want a live, at-a-glance read on per-session spend. The figures are the harness token count times your configured rates, not a provider invoice, so the provider bill remains the source of truth.
