dsh-billing-tui

Once a DeepSeek Harness conversation is running, your API spend stays a black box: you have no idea how much a single turn cost, whether the session is in the full-price peak window or the 50%-discount off-peak window, or how much cached-token hits saved you. dsh-billing-tui listens to every input, output, cache-hit, and reasoning token in real time, bills strictly against DeepSeek official peak/off-peak pricing, and pins a live readout (Cost: ¥1.2340 [Peak]) on the TUI status line so spend is always visible.

Type /billing in the chat stream and a persistent whale-ASCII register receipt is printed: per-model subtotals for input (cache hit / miss), output, and a grand total, all formatted with dot leaders that survive terminal spacing quirks. Repeating the command without new usage does not stack duplicate receipts, and child sessions forked from a model switch inherit the parent snapshot so costs never reset to zero. The plugin also exposes two Agent tools, show_billing and check_pricing_period, letting automation pipelines query spend and the current pricing window on their own.

Developers who work daily in the DSH terminal or Web UI with deepseek-v4-flash or deepseek-v4-pro get zero-config transparency out of the box. The plugin recognises only DeepSeek official models; Claude, GPT, local models, and unknown identifiers all return null and are never billed, eliminating any risk of misattributing a third-party price.
