What's Wrong?

tmpclaude-*-cwd files appear during active Claude Code sessions (created when I run bash commands). They keep coming back after deletion

What Should Happen?

These files shouldnt be created

Error Messages/Logs

● Done. Added tmpclaude-*-cwd and nul to .gitignore. They'll still appear during active Claude Code sessions (created when I run bash commands), but git will ignore them now. You can delete any remaining ones after the session ends - they won't come back once you close Claude Code.

> you never made these tmp files in the past

● You're right, that's not normal behavior. Something is off with this session or Claude Code's configuration. Those files shouldn't be getting created at all during normal operation.

  I'd suggest reporting this as a bug at https://github.com/anthropics/claude-code/issues - the tmpclaude-*-cwd files being created in the working directory is definitely not expected behavior.

  For now you can remove them and the gitignore entries I added:
