Bug Description

I'm trying to programmatically create a VM, run xyz steps, programmatically install Claude Code CLI and finally run some prompts. I have got to the part of executing some prompts and Claude just hangs. When I run through the workflow locally (installing claude code, asking it to write e.g., the Fibonacci function in Python) it works perfectly fine, but it does not on my VM:

Debugger in my VM:

Debugger locally:

... (the rest of claude -p "" execution debugging)

Hence why I believe it is something to do with this shell snapshot (or the shell in general).

What is the problem here?

Steps to Reproduce

1. Install claude using npm programmatically
2. run claude -p "Any prompt"

Expected Behavior

Claude to output "Balance too low" or something along those lines

Actual Behavior

Hangs
