dsh-claude-subscription

If you already hold a Claude Pro, Max, Team, or Enterprise subscription and want to call Claude models directly inside DeepSeek Harness, dsh-claude-subscription is built for exactly that. It authenticates through Anthropic's official OAuth browser flow — the same mechanism Claude Code uses — so no separate API key is required. Credentials stay in the local DSH credential service; they are never extracted, resold, or subject to extra billing.

Once you are logged in, the plugin continuously surfaces your subscription quota: the 5-hour window, the 7-day window, and the remaining percentage and reset time for Opus and Sonnet separately. All data is read locally from the Anthropic Usage API, and your access token never leaves the machine. When the token expires, a refresh token silently renews it with no manual step needed. You can optionally toggle a quota indicator on the right side of the chat input box, and if the subscription route is unavailable the plugin reports the error explicitly rather than silently falling back to another paid path.

The plugin currently targets DSH 0.1.2-alpha.5 and requires a valid Anthropic subscription account; any usage generated through it counts against your personal quota. It is ideal for DSH users who already subscribe to Claude and would rather not maintain a separate API key, especially those who want to switch models quickly and keep an eye on their subscription consumption in real time. Please review Anthropic's terms of service regarding third-party tool access.
