Focused task delegation
Give Grok a bounded investigation, review, comparison, public X research, or implementation-support task from a named workspace.
Route research, review, comparison, and implementation support to Grok Build while Codex owns scope, validation, and final decisions.

Use Grok as a dedicated delegation lane: send a well-scoped task, bring back evidence or a proposed change, then let Codex review and integrate the result. This wrapper is single-flight by design; when you coordinate multiple tracks, do it at the Codex workflow level rather than claiming Grok-internal parallelism.
Follow the getting-started guide, then read the delegation contract before authorizing a write task.
