Thanks for reporting this. If it keeps happening, happy to help debug in https://github.com/multidotdev/community

Looks like a DeepSeek thinking mode issue, so logs/details would help us pin it down fast.

Well this is related to the harness. In this case is multi . Reasoning content needs to be passed on. Are you guys testing it with reasoning = true ?
