Included Skills1

grok-companionskills/grok-companion/SKILL.md

Use when the user explicitly asks Codex to collaborate with Grok, or when an active host policy has pre-authorized automatic collaborator selection and selects Grok for a bounded task. Supports second opinions, review, adversarial review, research, bounded delegation, session continuation, and job management. Not for generic code review or web research without either activation path, exact X/Twitter retrieval or search (use superx), another named AI collaborator, or requests for a sidebar terminal.
