DeepSeek Harness Plugin: Balance and Usage Monitoring

dsh-balance-and-cost is a client plugin for DeepSeek Harness that monitors account balance, model consumption, and official time-based pricing. Its core features include real-time balance queries, consumption statistics by model and session, pricing that distinguishes peak and off-peak periods, and support for exporting detailed CSV data and hovering to view three tiers of token details. Plugin data is persisted, and you need to restart DSH after installation to use it.
