Command reference ยท Antigravity CLI
/btw
Asks a side question in the background without interrupting the main conversation.
/btw <question> belongs to the Utilities category of Antigravity CLI slash commands. The command sends a side question to a separate, ephemeral single-response agent that knows the context of the current conversation but works separately from the main thread. Meanwhile, the main conversation continues undisturbed, with the side question not affecting its context or token usage.
The command was originally introduced to allow brief side questions without interrupting the conversation thread; since then it has been revised multiple times, among other things to stream answers, make the agent's thinking process visible, and preserve the answer across conversation switches.
Distinction: /btw produces a standalone, one-time answer outside the main thread. For questions meant to influence the further course of the main task or feed into its context, the command is unsuitable - such questions belong directly in the main prompt.
โ WHEN TO USE IT?
Ask a brief additional question without interrupting the main task
/btw what does this function in utils.py do?
Ask a follow-up question and then switch to a different conversation without losing the answer
/btw where in the docs is the caching behavior described?
โ WHEN NOT TO?
The question is actually part of the main task
/btw runs as a standalone one-time answer separate from the main thread - unsuitable for questions meant to influence the further course of the main task.
Better: ask the question directly in the main prompt
A multi-step dialogue with follow-up questions and iterations is wanted
/btw starts an ephemeral single-response agent for exactly one answer, not for an ongoing dialogue.
Better: use a regular conversation, e.g. branch off from the current state via /fork
