What's Wrong?

I learned recently that Claude Code has ctrl+g feature and decided to use it. I was happy to be writing a long prompt in my text editor of choice. And then my text editor returned a non-zero exit status for stupid reasons despite the final content being in the tmp file (99% sure), and Claude Code shown "editor returned non-zero code" and just threw my edit completely away. You might imagine, I was not amused.

What Should Happen?

Probably better approach is to check if the file content changed, and at least _ask_ if it should use the new content.
