Bug: /context command output appears temporarily then vanishes without trace (v2.1.9 regression)

Summary

In Claude Code v2.1.9, the /context command output behaves strangely: it appears in a temporary full-screen view, then completely vanishes after a few seconds, leaving no trace in the conversation. This is a regression from v2.1.7 where the output was permanently appended to the chat history.

Steps to Reproduce

1. Start a Claude Code session (v2.1.9)
2. Have some conversation with Claude
3. Run /context command
4. Observe the behavior

What Happens (Bug)

| Step | Behavior |
|------|----------|
| 1 | Run /context |
| 2 | Brief pause (few seconds) |
| 3 | Output appears, taking over entire screen |
| 4 | After a few more seconds, output vanishes |
| 5 | Previous chat history returns, but /context output is gone |

The /context output acts like a temporary "flash" that disappears, as if the command was never run.

Expected Behavior (v2.1.7)

The /context output should be permanently appended below the chat history, visible when scrolling, and accessible to Claude in the conversation context.

Impact

• Users cannot review context information after the brief display
• Claude cannot see/reference the /context output (it's not in conversation history)
• The command becomes essentially useless for sharing context info with Claude

Environment

• Claude Code version: 2.1.9
• Platform: WSL2 (Linux)
• Terminal: Windows Terminal
