dsh-conversation-cost

Running long multi-turn conversations in DeepSeek Harness raises a deceptively simple question: how much did this session actually cost? The usual answer was to pause your work, open the DeepSeek billing page, and dig through line-item charges. dsh-conversation-cost removes that friction entirely—a cost badge now sits right beside the conversation title in the web UI, and hovering over it unfolds a step-by-step breakdown by model, token type, and peak/off-peak window, all without leaving the page.

Under the hood the plugin keeps things precise yet lightweight. Every LLM step is folded into a per-step usage record (input, cache-hit, and output tokens), linked to the model that actually executed it, and priced against the official rate card split by peak and off-peak windows. The badge and the hover card both show the amount in CNY and USD, with the exchange rate and per-model prices fully configurable. There are zero runtime dependencies and no build step: the host side is pure ESM and the browser side uses a hand-written module factory, so it drops in and starts updating the badge the moment each step completes.

If you run heavy daily workloads through Harness, want to keep a running eye on your API spend, or share a team quota and need transparent per-session accounting, this lightweight badge is the simplest cost dashboard you can add to your workflow.
