Maybe it would be good for you to add any benchmark or something that just will be doing it every version to compare if it works good or worse (SWE-bench Verified, SWE-bench Lite or SWE-bench Bash Only)

@rafek1241 thank you for the report. Do you have steps to consistently repro this that you can share?

add any benchmark or something

We do indeed run terminalbench and swebench on every change to the core agent loop. We also have an eval suite that we build out to cover product scenarios that don't end up getting tested by benchmarks. If you help us with a minimal repro, we can turn that into an eval.

@EvanBoyle
I cannot as I'm using that during my work. I'm happy to hear that you have some eval/benchmarks. It would be nice to see the test results also per your version. Maybe you can also prepare some debug logs when for an example something hang up/freeze or something, we could potentially in next copilot ssession ask for the "/dump" to get the metrics and logs for last sesion to be able to share such logs for you that would help you to reproduce the issue? What do you think?
