dsh-daily-ledger: A Local Daily Check-in and Ledger for DeepSeek Harness

`dsh-daily-ledger` is a local ledger and check-in plugin for DeepSeek Harness (DSH). It runs fully offline and does not upload data. Core features include daily check-ins, token and cost statistics (with support for daily, model-level, and itemized breakdowns), and a Web floating window for viewing status and customizing the background. The plugin automatically listens to DSH events to record usage, and supports configuring price snapshots and custom time zones. Installation is simple: you can check in or query statistics through chat commands, providing users with a convenient tool for local cost tracking and habit management.
