What's Wrong?

Issue:
The /context command briefly displays output then immediately disappears.
Previous chat messages remain visible.

Environment:

• Claude Code version: 2.1.12 (latest)
• OS: Windows 11 with WSL Ubuntu
• Node.js version: [run: node --version]

Steps to Reproduce:

1. Navigate to any project directory
2. Run /context
3. Output flashes briefly on screen
4. Output disappears completely
5. Previous messages remain visible

Expected: Output should remain visible
Actual: Output vanishes after brief flash

Duration: Started ~3-4 days ago

What Should Happen?

When running the /context command, the output should remain visible in the terminal/chat interface, displaying information about the current project context (files, directories, recent activity, etc.) similar to how other commands like /help display their output persistently.

Error Messages/Logs

No error messages are displayed. The command appears to execute successfully and generates output, but the output disappears from view immediately after rendering
  (within ~1 second). No errors in terminal, no crashes, session continues normally.

Steps to Reproduce

• /context 2>&1 | tee output.txt (command not capturable as it's internal CLI command)
• Checked ~/.claude/logs/ (no relevant error logs found)
