btw extension

This extension adds Claude Code-style /btw behavior to pi.

Behavior

• intercepts /btw <question> through the input pipeline instead of a normal extension command
• starts a separate model request immediately
• does not queue the question into the main agent loop
• does not interrupt the current task
• renders active requests and answers in a focused /btw panel while pi keeps working
• lets the user dismiss the panel with Esc/Enter, scroll long answers with ↑/↓, and clear displayed history with x
• stores hidden history as custom session entries (btw-history) without injecting answers into the visible transcript or main agent context

Why it is implemented this way

In pi, normal extension commands are checked before input expansion and are not the same as prompt templates or skills. To make /btw work while pi is already busy, this extension handles raw input that starts with /btw and launches its own background completion.

Extra shortcut

• Ctrl+Shift+B asks the current editor text as a side question
