dsh-claude-usage

Knowing how much Claude subscription quota you have left is the first question before kicking off a long coding session, yet the official CLI /usage command sends you back to a terminal while the DeepSeek Harness interface offers no built-in indicator. This plugin drops a plan-usage ring, carrying the Anthropic mark and matching the existing 28 px context-meter geometry, directly onto the right edge of the Settings row so quota visibility lives exactly where you already look.

Hover or keyboard-focus the ring to reveal a detailed quota panel: the 5-hour session window, the weekly window, model-scoped weekly limits, extra-usage state, and the current plan and rate-limit tier. Background polling runs on a five-minute cadence by default, a 250 ms debounced hover refresh keeps numbers current on demand, and the plugin honors Anthropic Retry-After cooldowns so it never out-races the provider rate limiter. A transient provider or network blip retains the last-good values rather than wiping the display.

On the security side, the plugin reads the local credentials file in strict read-only mode; the access token lives only inside the Host process for the duration of a single request. The web endpoint is loopback-bound, and every response passes through a normalizer that strips tokens, identifiers, emails, and unknown provider fields before anything reaches the browser. It is built for developers who use a Claude Code subscription daily within DeepSeek Harness and want at-a-glance quota and rate-limit visibility without ever leaving the workspace.
