What's Wrong?

Claude told me to report this after we've spent hours together trying to figure it out. I'm using the TUI on linux with a gnome terminal and ZSH shell, but I don't think the shell matters.

After a LOT of troubleshooting, I figured out that whenever Claude Code has a task, fetch is a perfect example, Claude just kept fetching example.com to test, and the white dot changes colors, to green in this case, the terminal no longer works properly. Enter gives a newline but does not send any input and backspace prints "^?" on the screen.

I've tried VT100, xterm, xterm-color256, etc. and it doesn't matter. I also made sure a permission prompt wasn't required. Simply starting claude code, resuming the session, tell Claude to fetch, and that's the last of me ever talking to Claude until I restart the program. I've gotten used to hitting ctrl-c after everything I type and resuming, but it's super annoying. Claude put all kinds of hooks in, etc, you name it, but finally told me to report this.

What Should Happen?

The terminal should still be functional.

Steps to Reproduce

Start Claude code.
Tell Claude code to fetch something, or anything that makes the dot beside whatever Claude is doing change colors.
In this case there will be a white dot to the left of "Fetch". Then the dot will turn green when completed.

That's it. Can no longer talk to Claude.
