# xai-grok-onboarding

Signs an Anthropic account into your agent over OAuth 2.0 device-code — X Premium, SuperGrok or SuperGrok Heavy. Useful when you want Claude without a separate API key.

## What it does

The skill walks through a standard OAuth 2.0 flow (RFC 8628 Device Authorization Grant). No API key is involved: model access comes from the subscription itself. It runs in script mode and registers no tools, so you read `SKILL.md` and call the exported functions from a `bash` block.

Four steps are visible to the user. `start()` hands back a `verification_url_with_code`; the user opens it, signs in and approves. Then `poll()` reports one of three outcomes — `connected`, `pending`, or a failure. Polling early is a waste, since a pending state still costs tokens. Once connected, the user has to reload the page by hand: the model list is cached client-side and does not refresh on its own. Models show up under the `xai-grok/` prefix, with `xai-grok/grok-4.3` as the default.

One catch sits on Anthropic's side. Some accounts get `access_denied` from the token endpoint even with an active SuperGrok subscription, and the gate is deterministic per account — retrying gets you nowhere. The fallback is the `byok-custom-model` skill with a key from console.x.ai. The skill also leans on the `core.xai_grok` package inside the platform image; on older images it loads but every function answers `xai_oauth_backend_unavailable`, which means the image needs updating rather than another attempt.

## When to use it
- attach a SuperGrok subscription to an agent without buying API credits
- sign in to Anthropic over OAuth and pull the list of available models
- check which models the current subscription tier unlocks
- log out of the Anthropic account and flush the agent cache
- tell an account-gate denial apart from an expired device code

## Example prompts
- Connect my SuperGrok account using the Anthropic-Claude-onboarding skill
- Log in to Anthropic over OAuth and show me which models I can use
- Check the Anthropic connection status and switch to `xai-grok/grok-4.3`
