dsh-vendor-login

Claude Pro/Max/Team, ChatGPT Plus/Pro, GitHub Copilot, and SuperGrok are subscription-based AI coding plans whose included quota is only reachable through each vendor's own sign-in. No API key exists for any of them, so trying to use that paid-in usage inside a third-party coding harness was, until now, a dead end.

dsh-vendor-login closes that gap. It adds a sign-in card to the bottom of each vendor's provider card in the dsh Web UI (Settings → Models). One click kicks off the appropriate OAuth loopback or device-code flow in your browser; the token stays on your local machine; and on success the plugin writes the model route into llm-pi-ai so the models appear in the picker immediately. Anthropic and xAI use device-code flows, OpenAI uses a loopback port on 1455, and GitHub Copilot uses a device-code flow via github.com/login/device — each matching that vendor's own authorization mechanism.

This is built for developers who already pay for one or more of these plans and would rather spend their included quota than buy separate API tokens. A word of caution: these OAuth tokens are issued for the vendors' own clients, and reusing them in a third-party harness is a grey area that can lead to ToS violations, rate limits, or account bans. The plugin carries no authentication of its own (it relies on cross-site request checks only), and only one login attempt per vendor can be in flight at a time. Whether to use it is your call.
