This is the prompt that Claude Code adds when you use /btw

https://github.com/Piebald-AI/claude-code-system-prompts/blo...

I found that helpful for a question but the btw query seemed to go to a subagent that couldn't interrupt or direct the main one. So it really was just for informational questions, not "hey what if we did x instead of y?"

That's not a thing in Claude ... so no.
