New command: /btw.

You can ask Claude a quick question while it’s mid-task — mid-generation, whenever. The answer pops up in an overlay and disappears when you dismiss it.

The key part: it doesn’t go into conversation history. No context bloat, no derailing the main task. It sees the full conversation but uses no tools, so it’s extremely lightweight — basically zero extra tokens.

One response only. No follow-ups. If you need a back-and-forth, use a normal prompt.

/btw what was the name of that config file again?
/btw explain the logic you're writing right now

I ask a lot of mid-task questions, so this fits my workflow really well. Before /btw, every small question added to the context and cost tokens on every future message. Now it’s just a quick peek and done.

It’s kind of the inverse of a subagent: /btw sees everything but can’t act. A subagent can act but starts with nothing.
