[BUG] Tool Calls immediately fail, misreporting as timeouts

What's Wrong?

Sometimes when Claude makes tool calls for long running bash commands with a timeout, the call is reporting back to Claude as a timeout

What Should Happen?

I don't expect a 5 minute timeout to be triggered in .5 seconds

Happens sometimes when there is an underlying error in the call and other times that's not the case

Error Messages/Logs

: Command timed out after 5m 0s

Steps to Reproduce

Not consistently reproducible unfortunately but I tend to see it on projects with an a compile step
