dsh-show-me-how-much: DeepSeek Harness Cost and Token Statistics Plugin

`dsh-show-me-how-much` is a local statistics plugin for DeepSeek Harness (DSH), designed to address the issues of delayed and unintuitive platform billing. It offers real-time cost display, detailed statistics panels, model identification, and data persistence. The plugin calculates costs based on the official DeepSeek V4 pricing table and is open source under the MIT license. Developers can install it via the command line and restart the service to use it. It is primarily used to estimate conversation costs and token consumption, although its estimates may differ from actual bills.
