dsh-opencode-go-meter: A DeepSeek Harness Plugin for Monitoring OpenCode Go Subscription Usage and Spending

willwhi/dsh-opencode-go-meter is a Web plugin for DeepSeek Harness (DSH), designed to address the pain point of frequently checking OpenCode Go subscription status and costs during development. The plugin integrates usage monitoring (5h/weekly/monthly) and spending directly into the conversation input area, with automatic fallback across dual data sources. It features credential security mechanisms, allowing read access only by Host processes and ensuring API key security. Installation requires dsh 0.1.0-rc.6 or later and a service restart; in use, click the button to view details, refresh manually, or update credentials.
