Feature Request: `/btw` — Interrupt & Ask Mid-Operation

What is /btw?

Both Claude CLI and QWEN CLI have a /btw feature. While the model is mid-operation (generating code, reviewing files, exploring a codebase), the user can type /btw to interrupt the model and ask a question about what it's cur$

The model then:

1. Pauses its current output
2. Answers the user's question
3. Resumes (or adjusts) what it was doing

Use Cases

• Model is writing a long refactor, user realizes a clarification is needed → /btw "wait, does this handle the edge case where X is null?"
• Model is exploring a codebase → /btw "also check the auth middleware"
• Model is reviewing code → /btw "what does that function actually do?"

Why Extensions Can't Add This

None of Command Code's user-extension mechanisms can implement /btw:

/btw requires changes to the core conversation event loop: listening for a special input during model output streaming, interrupting the stream, injecting context, and resuming. This is CLI-internal plumbing.

Request

Please add a /btw (or similar interrupt-and-ask) slash command that lets users pause the model mid-operation to ask clarifying questions.

Commencez par la boucle centrale d’événements de conversation et le chemin de streaming de la sortie du modèle décrits dans l’issue, puis suivez la manière dont l’entrée utilisateur est traitée pendant la génération. Déterminez le comportement requis pour l’interruption, l’injection de questions et la reprise ; le travail est considéré comme terminé lorsqu’un utilisateur peut invoquer /btw en cours d’opération, recevoir une réponse, puis reprendre ou ajuster la tâche d’origine.
