dsh-session-cost

After a long day of chatting with DeepSeek, it is hard to tell which sessions consumed the most tokens or cost the most money. dsh-session-cost solves exactly that: it reads the usage data reported by the model in session logs (the same source as the built-in token counter, not an estimate) and converts input, cache-hit, cache-write, and output tokens into CNY using a configurable price table.

Three entry points cover different workflows. On the agent side, the session_cost tool lets you ask in plain language how much one or several sessions cost, defaulting to the current conversation when no ID is given. On the user side, the /session-cost command and /session-cost-config price-table lookup are available at any time. In the UI, the sidebar session list renders the cumulative cost at the end of every row, so you can spot the most expensive conversation at a glance. The price table supports per-model overrides, making it easy to adapt to peak/off-peak rates or custom billing.

Ideal for developers who run DeepSeek Harness for iterative reasoning, batch experimentation, or long-running project conversations, especially when they need to track API spend per session, compare costs across dialogues, or report usage to a team. Pure JavaScript with no build step, ready to use right after install.
