[BUG] Claude Code v2.1.79 auto-interrupts every tool use without user input

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?

Claude Code repeatedly auto-interrupts all tool uses (Search, Read, Bash) with "Interrupted · What should Claude do instead?" without any user input. The session never completes any task.

Steps to reproduce:

1. Run claude in any project directory
2. Ask Claude to analyze code (e.g. trace a bug through multiple files)
3. Claude starts tool use (Search, Read, etc.) and immediately self-interrupts
4. This repeats in a loop until "Worked for Xs" and the prompt returns empty

Environment:

• Version: 2.1.79
• OS: macOS (darwin)
• Node: v18.20.8
• Tried both VS Code integrated terminal and external Terminal.app
• Reinstalling did not fix it

Expected: Claude completes tool use and returns analysis
Actual: Every tool use is interrupted automatically with no user action

What Should Happen?

Claude should complete all tool uses (Search, Read, Bash) and return a full analysis without interrupting itself.
