I removed a few fields for privacy, but I went to lunch, left claude-code open, and as you'll see it's triggering stop hook s every like 15-20 minutes. I have a python script logging the above on each stop hook call, and I send a notification which is why I noticed it.

Steps to Reproduce

1. Launch claude code and do something
2. Don't do anything for an hour
3. See hooks firing continuously, at least the STOP hook possibly others

Expected Behavior

Hooks only fire at the given event.
