Describe the enhancement you want to request

Ref: Anthropic rolled out /btw in Claude Code, their terminal-based AI coding assistant, letting developers type /btw plus a question—like explaining retry logic—for an instant overlay response. It draws from full conversation context without tools or history clutter, dismissible with a keypress, perfect for quick clarifications during long jobs. Thariq from the team demoed it refactoring code with exponential backoff, while engineer Erik Schluntz built it as a side project; developers praised its seamless multitasking and clean UX.

/btw is useful

[kjellknapen]

Opened a PR for it, don't know if it wil be picked up

[tobwen]

Just curious: Wouldn't it be better to make a plugin out of this? From my discussions on Discord, it became clear that the maintainers are committed to not including anything in the core that can also be solved with a plugin.

/btw is useful, codex has a similar feature "steer".

/btw is useful, codex has a similar feature "steer".

#17233 actually implements this into the app as a setting. There is the ability to set extra messages to be in "steer" rather than "queue" mode. not sure if this actually works yet or if it was just the setting setup.
