Overview

dsh-usage-plugin is a usage & cost tracker plugin in the DeepSeek Harness ecosystem (a DSH plugin shipped as a Host + Client two-in-one package). After installation, "Usage & Cost" and "Balance Query" tabs appear in the Web UI, right after "Conversation" and "Trace": Supports Windows / macOS / Linux: paths are handled per platform (node:path), and the folder picker / "reveal in file manager" use each OS's native mechanism (macOS: osascript / open; Linux: zenity / xdg-open). Balance query and export do not depend on Windows-only commands. Usage & Cost: records each model call's token usage and cache hits (input miss / cache hit / cache write / output / reasoning / finish reason), and computes cost using DeepSeek's peak/valley or base pricing (peak hours on weekdays are automatically priced by Beijing time 09:00–12:00 and 14:00–18:00; since 2026-08-23 weekends are billed entirely at the off-peak rate; since 2026-09-10 12:00 Beijing time the post-V4.1-Flash peak/valley prices apply — deepseek-flash off-peak cache hit 0.02 / input 1 / output 4 CNY, peak at twice that). Model names come from the actual request par
