Ask a side question with /btw in Grok Build

/btw asks a side question without interrupting the main turn. Official: Modes and Commands.

Run it

1. Open a Grok Build session (grok in the project, or resume with grok -c).
2. While a turn is running or you want a quick aside, type /btw plus your question and send.
3. Read the side answer. The main agent turn continues on its own track.

Example:

/btw what does this error code mean in the logs

When to use it

Use /btw for a short clarification, a definition, or a check that should not cancel or replace the job already in flight. For a full new job, queue a normal prompt (Ctrl+; / /queue) or wait for the turn to finish. For a recurring check, use /loop — see Run background tasks and loops in Grok Build.

Pitfalls

• Treating /btw as a second full agent with its own file edits — it is a side question on the current session.
• Cancelling the main turn when you only needed a quick aside.
