dsh-plugin-opencode-usage

When running an OpenCode Go subscription through DeepSeek Harness, the question that comes up most often is simple: how much quota is left? The official API returns only percentages and reset timestamps, and because different models carry different dollar quotas, converting to currency would introduce more confusion than clarity. dsh-plugin-opencode-usage turns that data into a glanceable floating panel tucked into the bottom-left corner of the chat window: one click reveals the rolling five-hour, weekly, and monthly usage—each showing used percent, remaining percent, and the upcoming reset time—refreshing itself every sixty seconds and dismissing cleanly with Esc or an outside click, all without interrupting the conversation in progress.

The panel deliberately registers in the shell overlay rather than the sidebar or input area, sidestepping conflicts with other plugins. A ResizeObserver keeps it pinned to the chat column through sidebar toggles, detail-panel changes, and window resizes, with automatic fallback if it would overflow the viewport. Security is handled by design: the API key is resolved only inside the Harness host process and never shipped to the browser—what the frontend sees is percentage data and nothing more.

If you are on a Web profile using an OpenCode Go subscription and want to keep an eye on how three time windows are filling up without ever leaving the chat interface, this plugin is that quiet little dot in the bottom-left corner. It does not support headless or CLI mode, and it performs no dollar-amount conversion. Its single job is to present the official percentages accurately, unobtrusively, and exactly where your gaze naturally lands.
