xAI Login Instructions

Use xai_login_instructions when the user needs setup commands or auth-file paths.

Default OAuth login writes a shared xAI OIDC entry to ~/.grok/auth.json. This is a shared auth store, not a requirement to use a specific Grok CLI build.

For browser login:

codex-xai-oauth login

For OAuth device login:

codex-xai-oauth login --device

For API-key fallback:

export XAI_API_KEY=xai-...

Credential safety:

• Do not expose token material.
• Prefer ~/.grok/auth.json unless CODEX_XAI_OAUTH_AUTH_FILE is explicitly set.
• Treat ~/.config/codex-xai-oauth/auth.json as a legacy fallback.
• Mention XAI_API_KEY only as an environment variable name, never as a value.
