Preflight Checklist

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

What's Wrong?

When network connectivity is briefly interrupted during a Claude Code session, the CLI becomes completely unresponsive. No keyboard input (Ctrl+C, Escape, /clear, etc.) restores functionality. The only recovery method is to close the terminal entirely and restart with claude.

Impact:
High - Loses all conversation context and requires full restart. Particularly frustrating during long sessions or complex tasks.

What Should Happen?

Expected Behavior:

• The CLI should detect connection timeout/failure and surface an error message
• Keyboard interrupts (Ctrl+C) should remain functional to cancel the hung request
• User should be able to retry or continue the session without full restart

Actual Behavior:

• CLI becomes completely frozen
• No user input is processed
• No timeout occurs (waited 5+ minutes)
• Process must be killed externally (pkill -f claude) or terminal closed

Error Messages/Logs

Steps to Reproduce

Steps to Reproduce:

1. Start a Claude Code session with claude
2. Begin a request (or have one in progress)
3. Experience a brief network interruption (WiFi dropout, VPN reconnect, ISP hiccup)
4. Observe that the CLI hangs indefinitely
5. Attempt Ctrl+C, Escape, or typing /clear - none work
6. Must close terminal and restart
