What's Wrong?

When running /btw without arguments, the usage hint displays HTML entities instead of literal characters:

Usage: /btw <your question>

The < and > around "your question" are being HTML-encoded as < and >.

What Should Happen?

The usage message should display literal angle brackets:

Usage: /btw <your question>

Steps to Reproduce

1. Open Claude Code CLI
2. Type /btw and press Enter (without any arguments)
3. Observe the usage hint message shows < and > instead of < and >
