dsh-balance: Real-Time Sidebar Balance Dashboard for DeepSeek Harness

dsh-balance is a lightweight plugin designed for DeepSeek Harness to display the current model provider’s balance directly in the sidebar. It supports automatic provider switching, recognizes DeepSeek’s peak/valley billing with red/green dot indicators, has zero dependencies, and weighs approximately 11kB. The plugin automatically refreshes every 60 seconds or on manual action and includes graceful error handling. Once installed, it works out of the box without configuration, and API keys are securely parsed only on the host side, making it a practical tool for improving cost control in multi-model debugging workflows.
