[BUG]

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

When running the /context command, the context panel appears on the right side of the terminal instead of displaying properly (centered/full-width). The panel then automatically dismisses itself after briefly appearing, without any user input to close it.

This behavior occurs consistently across all terminal emulators tested.

What Should Happen?

The /context panel should remain visible on screen with the chat input box beneath it, allowing the user to continue chatting while viewing context information.

Error Messages/Logs

No error messages. This is a visual/UI issue - the panel renders in the wrong position and auto-dismisses without any errors being displayed.

Steps to Reproduce

1. Open Claude Code in any terminal
2. Run /context
3. Observe the panel appears on the right side of the terminal
4. Panel auto-dismisses within 1-2 seconds without user interaction
