• Subagents

  SpaceXAI

  Independent child sessions with their own context; they return a summary to the parent. Built-in types: general-purpose, explore (read/list/search only), and plan (no shell, no edits). Add types under .grok/agents/ or ~/.grok/agents/. Personas are behavioral overlays via /personas.
