Tip suggests /btw command which does not exist

Description

Claude Code shows the following tip in the UI:

Tip: Use /btw to ask a quick side question without interrupting Claude's current work

When typing /btw, the response is:

Unknown skill: btw

The /btw command does not exist as a skill or built-in command, but the tip suggests it does.

Steps to reproduce

1. Open Claude Code
2. Wait for the tip to appear (or cycle through tips)
3. See the tip about /btw
4. Type /btw followed by a message
5. Get "Unknown skill: btw" error

Expected behavior

Either:

• The /btw command should work as described in the tip
• Or the tip should be removed if the feature does not exist

Environment

• Claude Code (latest version as of 2026-03-11)
• Ubuntu 24.04
